Black Arrow Cyber Threat Briefing 10 June 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

• Business Email Compromise (BEC) Attacks Have Risen 53% Year-Over-Year

Armorblox released a report which highlights the use of language-based attacks that bypass existing email security controls. The report uncovers how the continued increase in remote working has made critical business workflows even more vulnerable to new forms of email-based attacks, often resulting in financial fraud or credential theft.

Language-based attacks have become the new normal for business email compromise (BEC) with 74% of these attacks using language as the main attack vector.

Security teams spend a massive amount of time configuring rules and exceptions in their email security solutions to block impersonation emails – both for executives and other employees. Despite all of that manual work and rule writing, 70% of impersonation emails evaded email security controls.

• Ransomware Attacks Setting New Records

Zscaler released the findings of its annual ThreatLabz Ransomware Report, which revealed an 80 percent increase in ransomware attacks year-over-year.

In 2022, the most prevalent ransomware trends include double-extortion, supply chain attacks, ransomware-as-a-service, ransomware rebranding, and geo-political incited ransomware attacks. The report details which industries are being targeted the most by cyber criminals, explains the damage caused by double-extortion and supply chain attacks, and catalogues the most active ransomware groups operating today.

Modern ransomware attacks require a single successful asset compromise to gain initial entry, move laterally, and breach the entire environment, making legacy VPN and flat networks extremely vulnerable. Attackers are finding success exploiting weaknesses across businesses’ supply chains as well as critical vulnerabilities like Log4Shell, PrintNightmare, and others. And with ransomware-as-a-service available on the darkweb, more and more criminals are turning to ransomware, realising that the odds of receiving a big payday are high.

The tactics and scope of ransomware attacks have been steadily evolving, but the end goal continues to be a disruption of the target organisation and theft of sensitive information for the purposes of ransom. The size of the ransom often depends on the number of systems infected and the value of the data stolen: the higher the stakes, the higher the payment. In 2019, many ransomware groups updated their tactics to include data exfiltration, commonly referred to as a ‘double extortion’ ransomware.

• Hackers Are Now Hiding Inside Networks for Longer. That's Not a Good Sign

Cyber criminals are spending more time inside networks before they're discovered, and that's allowing them to do more damage.

The amount of time cyber criminal intruders are spending inside victims' networks is increasing, providing them with the ability to carry out higher complexity campaigns and more damaging cyber attacks.

According to analysis by cyber security researchers at Sophos, who examined incidents targeting organisations around the world and across a wide range of industry sectors, the median dwell time that cyber criminals spend inside compromised networks is now 15 days, up from 11 days the previous year.

Dwell time is the amount of time hackers are inside the network before they're discovered or before they leave – and being able to spend an increased amount of time inside a compromised network undetected means they're able to more carefully conduct malicious activity, such as monitoring users, stealing data or laying the foundations for a malware or ransomware attack.

• Paying Ransomware Paints Bigger Bullseye on Target’s Back

Ransomware attackers often strike targets twice, regardless of whether the ransom was paid.

Paying ransomware attackers doesn’t pay off and often paints a bigger target on a victim’s back. Eighty percent of ransomware victims that paid their attackers were hit a second time by the malware scourge.

New ransomware numbers come from a Cybereason’s April ransomware survey of 1,456 cyber security professionals. According to the gated report (registration required), victims that were successfully extorted were not only targeted a second time, but frequently data encrypted by criminals later became unusable during the decryption process because of corruption issues.

The fact that ransomware gangs strike so quickly a second and third time isn’t surprising, because they will try to profit in any possible way so why not hit the same company, demand a higher ransom, and get paid again?

• Organisations Fix Only 1 in 10 Vulnerabilities Monthly

New research from SecurityScorecard features a couple of eye-popping “only” findings: Only 10 percent of vulnerabilities are remediated each month, and only 60 percent of companies have improved their security profile despite a 15-fold increase in the number of cyber incidents in the last three years.

That’s not good. The research, which sought to measure how long it took the 1.6 million organisations assessed to remediate vulnerabilities in the three-year period from 2019 to 2022, also found the following:

·       53% had at least one exposed vulnerability to the internet, while 22% of organisations amassed more than 1,000 vulnerabilities each, confirming more progress is required to protect organisations’ critical assets.

·       The financial sector is among the slowest remediation rates (median to fix 50% = 426 days), while utilities ranked among the fastest (median = 270 days).

·       Despite a 15-fold increase in exploitation activity for vulnerabilities with published exploit code, there was little evidence that organisations in the financial sector fixed exploited flaws faster.

·       The IT sector (62.6%) and public sector (61.6%) had the highest prevalence of open vulnerabilities.

·       The financial sector (48.6%) exhibited the lowest proportion of open vulnerabilities; however, there is less than a 10% difference between this and other sectors in terms of industries with the most open vulnerabilities.

·       It typically takes organisations 12 months to remediate half of the vulnerabilities in their internet-facing infrastructure.

·       When firms have fewer than 10 open vulnerabilities, it can take about a month to close just half of them, but when the list grows into the hundreds, it takes up to a year to reach the halfway point.

• Cyber Attack Surface "Spiralling Out of Control"

Global organisations are still beset with cyber visibility and control challenges, with two-fifths (43%) admitting their digital attack surface is out of control as a result, according to new Trend Micro research.

The security vendor polled over 6200 IT and business decision-makers to compile its new study, ‘Mapping the digital attack surface: Why global organisations are struggling to manage cyber risk’.

It revealed that nearly three-quarters (73%) are concerned about the increasing size of their attack surface. Over a third (37%) said it is “constantly evolving and messy,” and just half (51%) thought they were able to fully define its extent.

These visibility challenges are greatest in cloud environments, although problems persist across the board. The report highlights complex supply chains, tool bloat and home working-driven shadow IT as additional contributory factors.

On average, respondents estimated having just 62% visibility of their attack surface.

• Phishing Hits All-Time High in Q1 2022

The first quarter of 2022 saw phishing attacks hit a record high, topping one million for the first time, according to data from the Anti Phishing Working Group (APWG).

The industry, law enforcement and government coalition’s new Phishing Activity Trends Report also revealed that March was the worst month on record for phishing, with 384,291 attacks detected.

The financial sector was the worst hit, accounting for 24% of all detected attacks, although webmail and SaaS providers were also popular targets.

Attacks spoofing retailers dropped 17% from the previous quarter to 15% following the busy holiday shopping season, while those against social media services rose significantly, from nearly 9% percent of all attacks to 13% over the same period.

• Ransomware's ROI Retreat Will Drive More BEC Attacks

Law enforcement crackdowns, tighter cryptocurrency regulations, and ransomware-as-a-service (RaaS) operator shutdowns are driving down the return on investment for ransomware operations across the globe.

A presentation at the RSA Conference last week laid out analysis of the ransomware threat landscape, predicting that there will be a pivot from ransomware toward renewed interest in basic business email compromise (BEC) attacks in the next 6 to 12 months.

Ransomware attacks grab headlines and have been supercharged by a few prolific RaaS operators, but crackdowns on just one group can make an enormous dent.

Ransomware is a centralised ecosystem with small numbers of operators responsible for the majority of attacks.

The recent disappearance of Pysa, left just two groups, Conti and Lockbit, with more than 50% of the share of the total ransomware attacks in the first half of 2022. BEC groups, on the other hand, are diffuse and scattered, making them much harder to eradicate.

Although they're not as quick to make the headlines, BEC attacks have cost business more than $43 billion since 2016, according to the FBI, and make up $1 out of every $3 lost to cyber attacks, far outpacing ransomware losses.

Ransomware has had a moment over the past couple of years, in part because once threat actors were able to abandon arcane wire transfers to collect ransoms and rely on cryptocurrency, caps on transactions were lifted and it became simple to collect much larger amounts. But new crypto regulations are chilling the ability of these cyber criminals to rely on its infrastructure to do business, adding "friction" to the transactions.

BEC attacks, by comparison, rely on social engineering to corrupt a business's financial supply chain to get employees to willingly part with the cash, making them exponentially harder to track and stop.

• The Real Cost of Cyber Attacks: What Organisations Should Be Prepared For

With each passing year, hackers and cyber criminals of all kinds are becoming more sophisticated, malicious, and greedy conducting brazen and often destructive cyber-attacks that can severely disrupt a company’s business operations. And this is a big problem, because, first and foremost, customers rely on a company’s ability to deliver services or products in a timely manner. Cyber attacks not only can affect customers’ data, but they can impact service delivery.

Data breaches and costs associated with them have been on the rise for the past few years, but, according to a 2021 report, the average cost per breach increased from $3.86 million in 2020 to $4.24 million in 2021. The report also identified four categories contributing most global data breach costs – Lost business cost (38%), Detection and escalation (29%), Post breach response (27%), and Notification (6%).

Ransomware attacks cost an average of $4.62 million (the cost of a ransom is not included), and destructive wiper-style attacks cost an average of $4.69 million, the report said.

For a business, a data breach is not just a loss of data, it can also have a long-lasting impact on operations and undermine customers’ trust in the company. In fact, a survey revealed that 87% of consumers are willing to take their business elsewhere if they don’t trust a company is handling their data responsibly. Therefore, the reputational damage might be detrimental to a business’ ability to attract new customers.

• Why Smishing and Vishing Attempts Surged In 2021

In The Human Factor Report 2022, security vendor Proofpoint found that SMS phishing (smishing) attacks more than doubled year-on-year in 2021. The report is based on their analysis of over 2.6 billion email messages, 49 billion URLs, 1.9 billion attachments, 28 million cloud accounts and 1.7 billion mobile messages.

The study details the most common attack surfaces and methods including categories of risk, vulnerabilities, attacks, Russian Aligned APT’s, and Privilege as a vector.

Key Findings:

• Managers and executives make up only 10% of users, but almost 50% of the most severe attack risk

• Attackers attempt to initiate more than 100,000 telephone-oriented attacks every day.

• Malicious URLS are 3-4x more common than malicious attachments.

• Smishing attempts more than doubled in the US over the year, while in the UK over 50% of lures are themed around delivery notification.

• More than 20 million messages attempted to deliver malware linked to eventual ransomware attack

• Data loss prevention alerts have stabilised as businesses adopt permanent hybrid work models.

• 80% of businesses are attacked by a compromised supplier account in any given month.

• 35% of cloud tenants that received a suspicious login also saw suspicious post-access activity.

• Know Your Enemy! Learn How Cyber Crime Adversaries Get In…

Cyber security vendor Sophos dug into the incident reports of 144 real-life cyber attacks investigated by its Rapid Response team during 2021.

What they found might not surprise you, but it’s vital information nevertheless, because it’s what really happened, not merely what might have.

Notably:

• Unpatched vulnerabilities were the entry point for close to 50% of the attackers.

• Attackers stuck around for more than a month on average when ransomware wasn’t their primary goal.

• Attackers were known to have stolen data in about 40% of incidents. (Not all data thefts can be proved, of course, given that there isn’t a gaping hole where your copy of the data used to be, so the true number could be much higher.)

• RDP was abused to circumnavigate the network by more than 80% of attackers once they’d broken in.

Intriguingly, if perhaps unsurprisingly, the smaller the organisation, the longer the crooks had generally been in the network before anyone noticed and decided it was time to kick them out.

In businesses with 250 staff and below, the crooks stuck around (in the jargon, this is known by the quaintly archaic automotive metaphor of dwell time) for more than seven weeks on average.

This compared with an average dwell time of just under three weeks for organisations with more than 3000 employees.

As you can imagine, however, ransomware criminals typically stayed hidden for much shorter periods (just under two weeks, instead of just over a month), not least because ransomware attacks are inherently self-limiting.

After all, once ransomware crooks have scrambled all your data, they’re out of hiding and straight into their in-your-face blackmail phase.

• Small Businesses Struggle with an Increase in Cyber Attacks

Part of the problem: They don’t believe they are targets, so they don’t make security a priority. Cyber attacks are becoming more common for small businesses, and many aren’t prepared to deal with an attack.

As small businesses have accelerated their adoption of new technologies for remote work, communication, production and sales during the pandemic, their expanded computer networks have created new vulnerabilities to phishing and ransomware attacks. But many small businesses still don’t expect to be targeted by hackers, so preparing for a cyber attack is well down their list of priorities.

Black Arrow Cyber Threat Briefing 22 April 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

• Why Ransomware Attacks Prefer Small Business Targets Rather Than Rich Enterprises

Enterprise businesses with 25,000 employees+ are less likely to get hit by a ransomware attack than smaller businesses — even though big companies typically can afford to pay higher ransoms, the 2022 CyberEdge Cyberthreat Defense Report concluded.

What explains hackers taking aim at small businesses more frequently than enterprise giants?  The answer: Damaging a critical infrastructure facility or similar disruptions are certain to catch the eye of federal law enforcement, or national governments — something that no hacker wants, CyberEdge said. Smaller to medium-sized firms, as it turns out, get hit more frequently by ransomware attacks, on average at roughly 70 percent, the report said.

Overall, some 71 percent of organisations have been bitten by ransomware in 2022, up a point and a half from last year and by 8.5 points in 2020. It’s companies of 10,000 to 24,999 employees that are the sweet spot for ransomware hackers, nearly 75 percent of which are victimised by cyber extortionists.

The extensive study, which surveyed 1,200 security decision makers and practitioners employed by companies of greater than 500 people in 17 countries across 19 industries, is geared to helping gauge their internal practices and investments against those of their counterparts in other parts of the world.

• Ransomware Plagues Finance Sector as Cyber Attacks Get More Complex

Cyber criminals have evolved from hacking wire transfers to targeting market data, as ransomware continues to hit financial firms, says a new VMware report. Here's what to do about it.

Ransomware plagues financial institutions as they face increasingly complex threats over previous years owing to the changing behaviour of cyber criminal cartels, according to VMware's latest Modern Bank Heists report.

This has happened as the cyber crime cartels have evolved beyond wire transfer frauds to target market strategies, take over brokerage accounts, and island-hop into banks, according to the report.

For the report, VMware surveyed 130 financial sector CISOs and security leaders from across different regions including North America, Europe, Asia Pacific, Central and South America, and Africa.

Report findings were consistent with observations by other security experts. "The Secret Service, in its investigative capacity to protect the nation's financial payment systems and financial infrastructure, has seen an evolution and increase in complex cyber-enabled fraud," says Jeremy Sheridan, former assistant director at the US Secret Service. "The persistent, inadequate security of systems connected to the internet provides opportunity and methodology."

• 76% of Organisations Worldwide Expect to Suffer a Cyber Attack This Year

Ransomware, phishing/social engineering, denial of service (DoS) attacks, and the business fallout of a data breach rank as the top concerns of global organisations, a new study shows.

The newly published Cyber Risk Index, a study by Trend Micro and the Ponemon Institute, shows that more than three-quarters of global organisations expect to suffer a cyber attack in the next 12 months — 25% of which say an attack is "very likely."

More than 80% of the 3,400 CISO and IT professionals and managers surveyed say their organisations were hit with one or more successful cyber attacks in the past 12 months, and 35% suffered seven or more attacks, according to the report, which covers the second half of 2021.

• Most Email Security Approaches Fail to Block Common Threats

A full 89 percent of organisations experienced one or more successful email breaches during the previous 12 months, translating into big-time costs.

On overwhelming number of security teams believe their email security systems to be ineffective against the most serious inbound threats, including ransomware.

That’s according to a survey of business customers using Microsoft 365 for email commissioned by Cyren and conducted by Osterman Research, which examined concerns with phishing, business email compromise (BEC), and ransomware threats, attacks that became costly incidents, and preparedness to deal with attacks and incidents.

“Security team managers are most concerned that current email security solutions do not block serious inbound threats (particularly ransomware), which requires time for response and remediation by the security team before dangerous threats are triggered by users,” according to the report, released Wednesday.

Less than half of those surveyed said that their organisations can block delivery of email threats. And, correspondingly, less than half of organisations rank their currently deployed email security solutions as effective.

https://threatpost.com/email-security-fail-block-threats/179370/

• Financial Leaders Grappling with More Aggressive and Sophisticated Attack Methods

VMware released a report which takes the pulse of the financial industry’s top CISOs and security leaders on the changing behaviour of cyber criminal cartels and the defensive shift of the financial sector.

The report found that financial institutions are facing increased destructive attacks and falling victim to ransomware more than in years past, as sophisticated cyber crime cartels evolve beyond wire transfer fraud to now target market strategies, take over brokerage accounts and island hop into banks.

In the Modern Bank Heists report, 63% of financial institutions admitted experiencing an increase in destructive attacks, with cyber criminals leveraging this method as a means to burn evidence as part of a counter incident response.

Additionally, 74% experienced at least one ransomware attack over the past year, with 63% paying the ransom. When asked about the nation-state actors behind these attacks, the majority of financial instructions stated that Russia posed the greatest concern, as geopolitical tension continues to escalate in cyberspace.

• Hackers Sneak Malware into Resumes Sent to Corporate Hiring Managers

A new set of phishing attacks delivering the ‘more_eggs’ malware has been observed striking corporate hiring managers with bogus resumes as an infection vector, a year after potential candidates looking for work on LinkedIn were lured with weaponised job offers.

"This year the more_eggs operation has flipped the social engineering script, targeting hiring managers with fake resumes instead of targeting jobseekers with fake job offers," eSentire's research and reporting lead, Keegan Keplinger, said in a statement.

The Canadian cyber security company said it identified and disrupted four separate security incidents, three of which occurred at the end of March. Targeted entities include a US-based aerospace company, an accounting business located in the UK, a law firm, and a staffing agency, both based out of Canada.

The malware, suspected to be the handiwork of a threat actor called Golden Chickens (aka Venom Spider), is a stealthy, modular backdoor suite capable of stealing valuable information and conducting lateral movement across the compromised network.

"More_eggs achieves execution by passing malicious code to legitimate windows processes and letting those windows processes do the work for them," Keplinger said. The goal is to leverage the resumes as a decoy to launch the malware and sidestep detection.

• West Warns of Russian Cyber Attacks as Concerns Rise Over Putin’s Nuclear Rhetoric

Cyber crime groups have publicly pledged support for Russia, western officials worry about Putin’s reliance on nuclear threats and the battle for Mariupol in Ukraine grinds on.

The US and four of its closest allies have warned that “evolving intelligence” shows that Russia is contemplating cyber attacks on countries backing Ukraine, as the Kremlin’s frustration grows at its failure to make military gains.

Vladimir Putin used the launch on Wednesday of a powerful new Sarmat intercontinental ballistic missile (ICBM), capable of carrying ten or more warheads, to make nuclear threats against western countries.

The Sarmat has long been in development and test flights were initially due to start in 2017. The Pentagon confirmed that the US had been given notice of the test and was not alarmed. Western officials are more concerned by the increasing emphasis Moscow puts on its nuclear arsenal as its conventional forces have faltered in Ukraine.

The Ukrainian army continued to put up resistance in the besieged and devastated city of Mariupol, but Putin’s Chechen ally, Ramzan Kadyrov, predicted that the last stand of the port’s defenders at the Azovstal steel works would fall on Thursday.

The Kremlin has made repeated threats against the many countries that have been supplying Ukraine’s army with modern weapons, and members of the “Five Eyes” intelligence sharing network – the US, Britain, Canada, Australia and New Zealand – predicted Moscow could also work with cyber crime groups to launch attacks on governments, institutions and businesses.

• Criminals Adopting New Methods To Bypass Improved Defences, Says Zscaler

The number of phishing attacks worldwide jumped 29 percent last year as threat actors countered stronger enterprise defences with newer methods, according to researchers with Zscaler's ThreatLabz research team.

Cyber criminals have adapted to multi-factor authentication (MFA), employee security awareness training, and security controls by broadening who and where they will attack.

While the United States remained the country with the most phishing attempts, others are seeing faster growth in the number of incidents – exploiting new vectors like SMS and lowering the barrier of entry for launching attacks through pre-built tools made available on the market.

"Phishing attacks continue to remain one of the most prevalent attack vectors, often serving as a starting point for more advanced next stage attacks that may result in a large-scale breach," Deepen Desai, CISO and vice president of security research and operations at Zscaler, told The Register.

• Cyber Criminals Are ‘Drinking the Tears’ of Ukrainians

In biology, when an insect drinks the tears of a large creature, it is called lachryphagy. And in cyberspace, malicious actors are likewise “drinking tears” by exploiting humanitarian concerns about the war in Ukraine for profit. Different forms of deception include tricking people into donating to bogus charities, clicking on Ukraine-themed malicious links and attachments, and even impersonating officials to extort payment for rescuing loved ones.

It is an unfortunate reality that cyber opportunists are engaging in lachryphagy to exploit humanitarian concerns about the war for profit or data collection. To date, one of the largest cryptocurrency scams involving fraudulent Ukrainian relief payments totalled $50 million in March, the Wall Street Journal reports.

Immediately following Russia’s invasion of Ukraine, cybersecurity companies warned the public that criminals were preying on Ukrainian relief fundraising efforts with cryptocurrency scams. Bitdefender Labs reports that cyber criminals have impersonated Ukrainian government entities and charitable organisations such as UNICEF, and the Australian humanitarian agency, Act for Peace. “Some [scammers] are even pretending to be Wladimir Klitschko, whose brother Vitali is mayor of Ukraine’s capital, Kyiv,” according to the BBC.

• Hackers For Hire Attempt to Destroy Hedge Fund Manager's Reputation

Hackers bombarded a British hedge fund manager with 3,000 emails and fake news stories about his mortgage in an effort to destroy his reputation after being hired by a corporate rival.

Criminals even sought to gain personal information about Matthew Earl by pretending to be his sister in a three-year campaign when he raised concerns over the controversial German payments company Wirecard.

Mr Earl, a former City analyst who runs the hedge fund ShadowFall, said he was targeted by a group called Dark Basin.

This group has been linked to Aviram Azari, who this week pleaded guilty in New York to a conspiracy to target journalists and critics of Wirecard using phishing emails.

Mr Earl said the hacking attempts started in 2016 after ShadowFall, nicknamed the “dark destroyer” in the City, criticised the financial performance of Wirecard. The German company was later mired in a series of accounting scandals and went bust.

He said: “I was being sent very targeted emails, which were crafted with personal information about my interests, friends and family’s details. They were very specific.”

Mr Earl received news stories that appeared to be from media outlets such as Reuters and Bloomberg. Another email appeared to be sent by his sister, sharing family photographs, he added.

• New Threat Groups and Malware Families Emerging

Mandiant announced the findings of an annual report that provides timely data and insights based on frontline investigations and remediations of high-impact cyber attacks worldwide. The 2022 report––which tracks investigation metrics between October 1, 2020 and December 31, 2021—reveals over 1,100 new threat groups and 733 new malware families.

The report also notes a realignment and retooling of China cyber espionage operations to align with the implementation of China’s 14th Five-Year Plan in 2021. The report warns that the national-level priorities included in the plan “signal an upcoming increase in China-nexus actors conducting intrusion attempts against intellectual property or other strategically important economic concerns, as well as defence industry products and other dual-use technologies over the next few years.”

Economic Warfare: Attacks on Critical Infrastructure Part of Geopolitical Conflict

We’ve known for years that since at least March of 2016, Russian government threat actors have been targeting multiple U.S. critical infrastructure sectors including the energy, nuclear, commercial facilities, water, aviation, and critical manufacturing sectors. The Department of Homeland Security (DHS), the Federal Bureau of Investigations (FBI), and other agencies have acknowledged this for quite some time in many of their technical alerts and statements.

In the intervening years, with the acceleration of digital transformation, cyber criminals and nation-state actors have increasingly set their sights on these sectors. The convergence of physical and digital assets brings competitive advantage but also inevitable risks. Attacks against hospitals, oil pipelines, food supply chains, and other critical infrastructure, have brought into sharp focus the vulnerability of cyber-physical systems (CPS) and the impact on lives and livelihoods when they are disrupted. Now, overwhelming signs indicate critical infrastructure companies are in the bullseye of geopolitical conflict.

Black Arrow Cyber Threat Briefing 18 March 2022

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.

Top Cyber Stories of the Last Week

Guernsey Cyber Security Warning for Islanders and Businesses

There has been a rise in cyber-attacks since the war in Ukraine began, according to the States of Guernsey and a cyber-security firm.

The States said: "We have seen a noticeable increase in the number of phishing emails since the war began."

The Channel Islands see more than 10 million cyber attacks every month, according to research by Guernsey firm Black Arrow Cyber Consulting.

It encouraged vigilance, as the islands are not immune to these attacks.

A States spokesman said: "The whole community needs to remain vigilant against such emails, which are designed to appear to be from reputable sources in order to dupe people into providing personal information or access to their device via the clicking of a link."

Bruce McDougall, from Black Arrow Cyber Consulting, said: "Criminals don't let a good opportunity go to waste. So they're conducting scams encouraging people to make false payments in the belief they're collecting for charities."

CISOs Face 'Perfect Storm' Of Ransomware and State-Supported Cyber Crime

As some nations turn a blind eye, defence becomes life-or-death matter

With ransomware gangs raiding network after network, and nation states consciously turning a blind eye to it, today's chief information security officers are caught in a "perfect storm," says Cybereason CSO Sam Curry.

"There's this marriage right now of financially motivated cyber crime that can have a critical infrastructure and economic impact," Curry said during a CISO roundtable hosted by his endpoint security shop. "And there are some nation states that do what we call state-ignored sanctioning," he continued, using Russia-based REvil and Conti ransomware groups as examples of criminal operations that benefit from their home governments looking the other way. 

"You get the umbrella of sovereignty, and you get the free license to be a privateer in essence," Curry said. "It's not just an economic threat. It's not just a geopolitical threat. It's a perfect storm."

It's probably not a huge surprise to anyone that destructive cyber attacks keep CISOs awake at night. But as chief information security officers across industries — in addition to Curry, the four others on the roundtable spanned retail, biopharmaceuticals, electronics manufacturing, and a cruise line — have watched threats evolve and criminal gangs mature, it becomes a battle to see who can innovate faster; the attackers or the defenders.

Four Key Risks Exacerbated by Russia’s Invasion of Ukraine

Russia’s invasion of Ukraine has altered the emerging risk landscape, and it requires enterprise risk management (ERM) leaders to reassess previously established organisational risk profiles in at least four key areas, according to Gartner.

“Russia’s invasion of Ukraine has increased the velocity of many risks we have tracked on a quarterly basis in our Emerging Risks survey,” said Matt Shinkman, VP with the Gartner Risk and Audit Practice.

“As ERM leaders reassess their organisational risk models, they must also ensure a high frequency of communication with the C-Suite as to the critical changes that require attention now.”

There are four major areas of risk that ERM leaders should continually monitor and examine their mitigation strategies as part of a broader aligned assurance approach as the war continues: Talent Risk, Cyber Security Risk, Financial Risk and Supply Chain Risk

These Four Types of Ransomware Make Up Nearly Three-Quarters of Reported Incidents

Any ransomware is a cyber security issue, but some strains are having more of an impact than others.

Ransomware causes problems no matter what brand it is, but some forms are noticeably more prolific than others, with four strains of the malware accounting for a combined total of almost 70% of all attacks.

According to analysis by cyber security company Intel 471, the most prevalent ransomware threat towards the end of 2021 was LockBit 2.0, which accounted for 29.7% of all reported incidents. Recent victims of LockBit have included Accenture and the French Ministry of Justice. 

Almost one in five reported incidents involved Conti ransomware, famous for several incidents over the past year, including an attack against the Irish Healthcare Executive. The group recently had chat logs leaked, providing insights into how a ransomware gang works. PYSA and Hive account for one in 10 reported ransomware attacks each.

"The most prevalent ransomware strain in the fourth quarter of 2021 was LockBit 2.0, which was responsible for 29.7% of all reported incidents, followed by Conti at 19%, PYSA at 10.5% and Hive at 10.1%," said the researchers.

Critical Infrastructure Threat as Ransomware Groups Target 'Enemies of Russia'

The cyber crime underground has fractured into pro-Ukraine and pro-Russia camps, with the latter increasingly focused on critical national infrastructure (CNI) targets in the West, according to a new report from Accenture.

The consulting giant’s Accenture Cyber Threat Intelligence (ACTI) arm warned that the ideological schism could spell mounting risk for Western organisations as pro-Kremlin criminal groups adopt quasi-hacktivist tactics to choose their next victims.

Organisations in the government, media, finance, insurance, utilities and resources sectors should be braced for more attacks, said ACTI.

Cyber Insurance War Exclusions Loom Amid Ukraine Crisis

An expanding threat landscape is testing the limits of cyber insurance coverage.

The industry experienced a rapid maturation over the past three years as enterprises required a broader umbrella of insurance coverage to combat increasing cyber risks. While demands and premiums continue to rise, one recent area of contention involves war and hostile acts, an exclusion that's becoming harder to categorize.

A judgment in December, coupled with the Russian invasion last month that posed potential cyber retaliations to Ukraine allies, highlighted shortcomings in insurance policies when it comes to cyber conflicts.

Zelenskyy Deepfake Crude, But Still Might Be a Harbinger of Dangers Ahead

Several deepfake video experts called a doctored video of Ukrainian President Volodymyr Zelenskyy that went viral this week before social media platforms removed it a poorly executed example of the form, but nonetheless damaging.

Elements of the Zelenskyy deepfake — which purported to show him calling for surrender — made it easy to debunk, they said. But that won’t always be the case.

Cyber Crooks’ Political In-Fighting Threatens the West

They’re choosing sides in the Russia-Ukraine war, beckoning previously shunned ransomware groups and thereby reinvigorating those groups’ once-diminished power.

A rift has formed in the cyber crime underground: one that could strengthen, rather than cripple, the cyber-onslaught of ransomware.

According to a report, ever since the outbreak of war in Ukraine, “previously coexisting, financially motivated threat actors divided along ideological factions.”

“Pro-Ukrainian actors are refusing to sell, buy, or collaborate with Russian-aligned actors, and are increasingly attempting to target Russian entities in support of Ukraine,” wrote researchers from Accenture’s Cyber Threat Intelligence (ACTI). “However, pro-Russian actors are increasingly aligning with hacktivist-like activity targeting ‘enemies of Russia,’ especially Western entities due to their claims of Western warmongering.”

What might otherwise seem like a good thing – bad guys fighting bad guys – may in fact pose an increased threat to the West.

Cloud-Based Email Threats Surge 50% in 2021

There was a 50% year-on-year surge in cloud-based email threats in 2021, but a drop in ransomware and business email compromise (BEC) detections as attacks became more targeted, according to Trend Micro.

The security vendor’s 2021 roundup report, Navigating New Frontiers, was compiled from data collected by customer-installed products and cloud-based threat intelligence.

It revealed that Trend Micro blocked 25.7 million email threats targeting Google Workspace and Microsoft 365 users last year, versus 16.7 million in 2020.

The number of phishing attempts almost doubled during the period, as threat actors continued to target home workers. Of these, 38% were focused on stealing credentials, the report claimed.

https://www.infosecurity-magazine.com/news/cloudbased-email-threats-surge-2021/

Millions of New Mobile Malware Strains Blitzed Enterprise in 2021

Researchers uncovered more than two million new mobile malware samples in the wild last year, Zimperium said in a new report.

Those threats spanned some 10 million mobile devices in at least 214 countries, the Dallas, Texas-based solution provider said in its newly released 2022 Global Mobile Threat Report. Indeed, mobile malware proved in 2021 to be the most prevalent security threat to enterprises, encountered by nearly 25 percent mobile endpoints among Zimperium’s customers worldwide. The 2.3 million new mobile strains Zimperium’s researchers located amount to nearly 36,000 new strains of malware weekly and roughly 5,000 each day.

UK Criminal Defence Lawyer Hadn't Patched When Ransomware Hit

Criminal defence law firm Tuckers Solicitors is facing a fine from the UK's data watchdog for failing to properly secure data that included information on case proceedings which was scooped up in a ransomware attack in 2020.

The London-based business was handed a £98,000 penalty notice by the Information Commissioner's Office under Article 83 of the EU's General Data Protection Regulation 2018.

The breach was first noted by Tuckers on August 23 2020 when part of its IT system became unavailable. On closer inspection, resident techies found a note from the attackers confirming they had compromised part of the infrastructure. The Microsoft Exchange server was out of action and two days' worth of emails were lost, as detailed by the company blog at the time.

https://www.theregister.com/2022/03/15/brit_solicitor_fined_for_failing/

Russian Ransomware Gang Retool Custom Hacking Tools of Other APT Groups

A Russian-speaking ransomware outfit likely targeted an unnamed entity in the gambling and gaming sector in Europe and Central America by repurposing custom tools developed by other APT groups like Iran's MuddyWater, new research has found.

The unusual attack chain involved the abuse of stolen credentials to gain unauthorized access to the victim network, ultimately leading to the deployment of Cobalt Strike payloads on compromised assets, said Felipe Duarte and Ido Naor, researchers at Israeli incident response firm Security Joes, in a report published last week.

Although the infection was contained at this stage, the researchers characterized the compromise as a case of a suspected ransomware attack.

The intrusion is said to have taken place in February 2022, with the attackers making use of post-exploitation tools such as ADFind, NetScan, SoftPerfect, and LaZagne. Also employed is an AccountRestore executable to brute-force administrator credentials and a forked version of a reverse tunneling tool called Ligolo.

The Massive Impact of Vulnerabilities in Critical Infrastructure

Recent cyber events have shown how extremely vulnerable critical infrastructure is. What are the biggest security concerns?

In any world conflict, one of the primary threats posed is cyber actors disabling or destroying the core infrastructure of the adversary. Based on the global reaction to the current world conflict, countries fear reprisals. The worry is that there will be collateral damage to the critical infrastructure of other countries not directly involved in the current conflict.

Today, services such as healthcare systems, power grids, transportation and other critical industries are increasingly integrating their operational technology with traditional IT systems in order to modernize their infrastructure, and this has opened up a new wave of cyber attacks. Though businesses are ramping up their security initiatives and investments to defend and protect, their efforts have largely been siloed, reactive, and lack business context. Lack of visibility of risk across the estate is a huge problem for this sector.

Top Cyber Stories of the Last Week

Cyber Criminals Shifting Focus: IT Sector Most Targeted In 2021

Darktrace reported that the IT and communications sector was globally the most targeted industry by cybercriminals in 2021.

Darktrace’s data is developed by ‘early indicator analysis’ that looks at the breadcrumbs of potential cyber-attacks at several stages before they are attributed to any particular actor and before they escalate into a full-blown crisis. Findings show that its artificial intelligence autonomously interrupted an average of 150,000 threats per week against the sector in 2021.

The IT and communications sector includes telecommunications providers, software developers, and managed security service providers, amongst others. There was also a growing trend of hackers targeting backup servers in an attempt to deliberately disable or corrupt backup files by deleting a single index file that would render all backups inaccessible. Attackers could then launch ransomware attacks against the clients of the backup vendor, preventing recovery and forcing payment.

In 2020, the most attacked industry was the financial and insurance sector, showing that cyber-criminals have shifted their focus over the last 12 months.

Over the last 12 months, it is clear that attackers are relentlessly trying to access the networks of trusted suppliers in the IT and communications sector. Quite simply, it is a better return on investment than, for example, going after one company in the financial services sector. SolarWinds and Kaseya are just two well-known and recent examples of this. Sadly, there is likely to be more in the near term.

The findings of this research mark one year since the compromise of US software company SolarWinds rattled the security industry. This landmark supply-chain attack made thousands of organisations vulnerable to infiltration by inserting malicious code into the Orion system. Over the last 12 months, there has been a continued spate of attacks against the IT and communications sector, including the high-profile attacks on Kaseya and Gitlab.

New Ransomware Variants Flourish Amid Law Enforcement Actions

Ransomware groups continue to evolve their tactics and techniques to deploy file-encrypting malware on compromised systems, notwithstanding law enforcement's disruptive actions against the cyber crime gangs to prevent them from victimizing additional companies.

"Be it due to law enforcement, infighting amongst groups or people abandoning variants altogether, the RaaS [ransomware-as-a-service] groups dominating the ecosystem at this point in time are completely different than just a few months ago," Intel 471 researchers said in a report published this month. "Yet, even with the shift in the variants, ransomware incidents as a whole are still on the rise."

Sweeping law enforcement operations undertaken by government agencies in recent months have brought about rapid shifts in the RaaS landscape and turned the tables on ransomware syndicates like Avaddon, BlackMatter, Cl0p, DarkSide, Egregor, and REvil, forcing the actors to slow down or shut down their businesses altogether.

93% of Tested Networks Vulnerable to Breach, Pen Testers Find

Data from dozens of penetration tests and security assessments suggest nearly every organisation can be infiltrated by cyber attackers.

The vast majority of businesses can be compromised within a month by a motivated attacker using common techniques, such as compromising credential, exploiting known vulnerabilities in software and Web applications, or taking advantage of configuration flaws, according to an analysis of security assessments by Positive Technologies.

In 93% of cases, an external attacker could breach a target company's network and gain access to local devices and systems, the company's security service professionals found. In 71% of cases, the attacker could affect the businesses in a way deemed "unacceptable." For example, every bank tested by the security firm could be attacked in a way that disrupted business processes and reduced the quality of their service.

Dridex Malware Trolls Employees With Fake Job Termination Emails

A new Dridex malware phishing campaign is using fake employee termination emails as a lure to open a malicious Excel document, which then trolls the victim with a season's greeting message.

Dridex is a banking malware spread through malicious emails that was initially developed to steal online banking credentials. Over time, the developers evolved the malware to use different modules that provide additional malicious behaviour, such as installing other malware payloads, providing remote access to threat actors, or spreading to other devices on the network.

This malware was created by a hacking group known as Evil Corp, which is behind various ransomware operations, such as BitPaymer, DoppelPaymer, WastedLocker variants, and Grief. Due to this, Dridex infections are known to lead to ransomware attacks on compromised networks.

More Than 35,000 Java Packages Impacted By Log4j Flaw, Google Warns

The Google Open Source Team scanned the Maven Central Java package repository and found that 35,863 packages (8% of the total) were using versions of the Apache Log4j library vulnerable to Log4Shell exploit and to the CVE-2021-45046 RCE.

“More than 35,000 Java packages, amounting to over 8% of the Maven Central repository (the most significant Java package repository), have been impacted by the recently disclosed log4j vulnerabilities (1, 2), with widespread fallout across the software industry.” reads the report published by Google. “As far as ecosystem impact goes, 8% is enormous.”

The Google experts used the Open Source Insights, a project used to determine open source dependencies, to assess all versions of all artifacts in the Maven Central Repository.

The experts pointed out that the direct dependencies account for around 7,000 of the affected packages. Most of the affected artifacts are related to indirect dependencies.

Since the vulnerability was disclosed, 13% of all vulnerable packages have been fixed (4,620).

Log4j Flaw: Attackers Are 'Actively Scanning Networks' Warns New Guidance, Joint Advisory from Cyber Agencies in US, Australia, Canada, New Zealand and the United Kingdom

A new informational Log4J advisory has been issued by cybersecurity leaders from the US, Australia, Canada, New Zealand and the United Kingdom. The guide includes technical details, mitigations and resources to address known vulnerabilities in the Apache Log4j software library.

The project is a joint effort by the US' Cybersecurity and Infrastructure Security Agency (CISA), FBI and NSA, as well as the Australian Cyber Security Centre (ACSC), Canadian Centre for Cyber Security (CCCS), Computer Emergency Response Team New Zealand (CERT NZ), New Zealand National Cyber Secure Centre (NZ NCSC), and the United Kingdom's National Cyber Security Centre (NCSC-UK).

The organisations said they issued the advisory in response to "active, worldwide exploitation by numerous threat actors, including malicious cyber threat actors." Numerous groups from North Korea, Iran, Turkey and China have been seen exploiting the vulnerability alongside a slate of ransomware groups and cybercriminal organisations.

Conti Ransomware Gang Has Full Log4Shell Attack Chain

The Conti gang was the first professional-grade, sophisticated ransomware group to weaponise Log4j2, now with a full attack chain.

The Conti ransomware gang, which last week became the first professional crimeware outfit to adopt and weaponize the Log4Shell vulnerability, has now built up a holistic attack chain.

The sophisticated Russia-based Conti group – which Palo Alto Networks has called “one of the most ruthless” of dozens of ransomware groups currently known to be active – was in the right place at the right time with the right tools when Log4Shell hit the scene 10 days ago, security firm Advanced Intelligence (AdvIntel) said in a report shared with Threatpost on Thursday.

As of Monday the attack chain has taken the following form, AdvIntel’s Yelisey Boguslavskiy told Threatpost: Emotet -> Cobalt Strike -> Human Exploitation -> (no ADMIN$ share) -> Kerberoast -> vCenter ESXi with log4shell scan for vCenter.

Second Ransomware Family Exploiting Log4j Spotted In US, Europe

This was quickly followed by a second ransomware group when researchers found a second family of ransomware has been growing in usage for attack attempts that exploit the critical vulnerability in Apache Log4j, including in the US and Europe.

A number of researchers, including at cybersecurity giant Sophos, have now said they’ve observed the attempted deployment of a ransomware family known as TellYouThePass. Researchers have described TellYouThePass as an older and largely inactive ransomware family — which has been revived following the discovery of the vulnerability in the widely used Log4j logging software.

Threat actors steal $80 million per month with fake giveaways, surveys

Scammers are estimated to have made $80 million per month by impersonating popular brands asking people to participate in fake surveys or giveaways.

Researchers warn of this new trend in global fraud schemes involving targeted links to make investigation and take-down increasingly challenging.

According to current estimates, these massive campaigns resulted in an estimated $80,000,000 per month, stolen from 10 million people in 91 countries.

The scam themes are the typical and "trustworthy" fake surveys and giveaways from popular brands with the holiday season making targets more susceptible to fraudulent gift offerings.

According to a report by Group-IB, there are currently 60 known scam networks that use targeted links in their campaigns, impersonating 121 brands in false giveaways.

Each network uses an average of 70 different Internet domain names as part of their campaigns, but some find great success with fewer domains, which indicates that quality beats quantity when it comes to scams.

Microsoft Teams might have a few serious security issues

Security researchers have discovered four separate vulnerabilities in Microsoft Teams that could be exploited by an attacker to spoof link previews, leak IP addresses and even access the software giant's internal services.

These discoveries were made by researchers at Positive Security who “stumbled upon” them while looking for a way to bypass the Same-Origin Policy (SOP) in Teams and Electron according to a new blog post. For those unfamiliar, SOP is a security mechanism found in browsers that helps stop websites from attacking one another.

During their investigation into the matter, the researchers found that they could bypass the SOP in Teams by abusing the link preview feature in Microsoft's video conferencing software by allowing the client to generate a link preview for the target page and then using either summary text or optical character recognition (OCR) on the preview image to extract information.

The Future of Work Has Changed, and Your Security Mindset Needs to Follow

VPNs have become a vulnerability that puts organisations at risk of cyber attacks.

When businesses first sent employees to work from home in March 2020 — thinking it'd only be for two weeks — they turned to quick fixes that would enable remote work for large numbers of people as quickly as possible. While these solutions solved the short-term challenge of allowing distributed workforces to connect to a company's network from anywhere, they're now becoming a security vulnerability that is putting organisations at risk of growing cyberattacks.

Now that almost two years have passed and work has fundamentally shifted, with fully or hybrid remote environments here to stay, business and security leaders need solutions that better fit their unique and increasingly complex needs. In fact, a new survey from Menlo Security has found that 75% of organisations are re-evaluating their security strategies for remote employees, exemplifying that accommodating remote work is a top priority for the majority of business leaders.

To successfully manage the risks that distributed workforces entail, leaders must shift their mindset away from the hub-and-spoke approach of providing connectivity to the entire network, instead segmenting access by each individual private application, wherever it is deployed, as threats of cyberattacks loom across all industries. As organisations grapple with the added security challenges that remote and hybrid work environments bring, adopting a zero-trust approach will be critical for end-to-end network and endpoint protection.
