Top Cyber Stories of the Last Week

 84% Of Organisations Experienced Phishing Or Ransomware Attacks In The Last Year

A new report from Trend Micro has found that 84% of organisations have reported phishing or ransomware security incidents in the last 12 months.

The findings come from an Osterman Research study commissioned by Trend Micro that was compiled from interviews with cyber security professionals in midsize and large organisations nationwide. The research also found that half of organisations are not effective at countering phishing and ransomware threats.

https://www.itpro.co.uk/security/ransomware/360191/84-of-organizations-experienced-phishing-or-ransomware-attacks-in-last

Phishing continues to be one of the easiest paths for ransomware

Ransomware gangs are still using phishing as one of the main ways to attack an organisation, according to a new survey from Cloudian featuring the insights of 200 IT decision-makers who experienced a ransomware attack over the last two years.

More than half of all respondents have held anti-phishing training among employees, and 49% had perimeter defenses in place when they were attacked.

Nearly 25% of all survey respondents said their ransomware attacks started through phishing, and of those victims, 65% had conducted anti-phishing training sessions. For enterprises with fewer than 500 employees, 41% said their attacks started with phishing. About one-third of all victims said their public cloud was the entry point ransomware groups used to attack them.

Ransomware: Only Half Of Organisations Can Effectively Defend Against Attacks, Warns Report

Around half of firms don't have the technology to prevent or detect ransomware attacks, according to research by cybersecurity company Trend Micro. It suggests that many organisations don't have the cybersecurity capabilities required to prevent ransomware attacks, such as the ability to detect phishing emails, remote desktop protocol (RDP) compromise or other common techniques deployed by cyber attackers during ransomware campaigns. 

For example, the report warns that many organisations struggle with detecting the suspicious activity associated with ransomware and attacks that could provide early evidence that cyber criminals have compromised the network. That includes failing to identify unusual lateral movement across corporate networks, or being able to spot unauthorised users gaining access to corporate data.

https://www.zdnet.com/article/ransomware-only-half-of-organisations-can-effectively-defend-against-attacks-warns-report/

MI5 Chief Warns Public Of Cyber-Threat From Hostile States Such As China & Russia

Head of Britain's MI5, Ken McCallum, is urging the public to be as vigilant about threats from "hostile states" as from terrorism.

These include disruptive cyber-attacks, misinformation, espionage and interference in politics - and are usually linked to Russia and China.

McCallum is warning that "less visible threats... have the potential to affect us all," affecting UK jobs and public services and could even lead to a loss of life.

The head of the Security Service wants to challenge the idea that activity by so-called "hostile states", usually taken to mean primarily Russia and China, only affects governments or certain institutions.

Instead, he is to argue in an annual threat update, that the British public are not immune to the "tentacles" of covert action by other states.

In the speech at MI5's Thames House headquarters, Mr McCallum will warn the "consequences range from frustration and inconvenience, through loss of livelihood, potentially up to loss of life".

Almost All Organisations Have Suffered Insider Data Breaches

Egress’ Insider Data Breach Survey 2021 claims that 94 percent of organisations have experienced insider data breaches in the last year. Human error was the top cause of serious incidents, according to 84 percent of IT leaders surveyed.

However, IT leaders are more concerned about malicious insiders, with 28 percent indicating that intentionally malicious behaviour is their biggest fear. Despite causing the most incidents, human error came bottom of the list, with just over one-fifth (21 percent) saying that it’s their biggest concern.

Additionally, almost three-quarters (74 percent) of organisations have been breached because of employees breaking security rules, and 73 percent have been the victim of phishing attacks.

The survey, independently conducted by Arlington Research on behalf of Egress, surveyed 500 IT leaders and 3,000 employees in the US and UK across vertical sectors including financial services, healthcare and legal.

https://workplaceinsight.net/almost-all-organisations-have-suffered-insider-data-breaches/

Cyber Crime Costs Organisations Nearly $1.79 Million Per Minute

Cybercrime costs organisations an incredible $1.79m every minute, according to RiskIQ’s 2021 Evil Internet Minute Report.

The study, which analysed the volume of malicious activity on the internet, laid bare the scale and damage of cyber-attacks in the past year, finding that 648 cyber-threats occurred every minute.

The researchers calculated that the average cost of a breach is $7.2 per minute, while the overall predicted cybersecurity spend is $280,060 every minute.

E-commerce has been heavily hit by online payment fraud in the past year, with cyber-criminals taking advantage of the shift to online shopping during the COVID-19 pandemic. While the e-commerce industry saw a record $861.1bn in sales, it lost $38,052 to online payment fraud every minute.

https://www.infosecurity-magazine.com/news/cybercrime-costs-orgs-per-minute/

Phishing, Ransomware Driving Wave of Data Breaches

Data compromises have increased every month this year except May.

If that trend continues, or even if there is only an average of 141 new compromises per month for the next six months, the total will still exceed the previous high of 1,632 breaches set in 2017.

These were among the findings of the nonprofit organization Identity Theft Resource Center’s (ITRC) latest data breach analysis report, which revealed publicly reported U.S. data breaches are up 38% in the second quarter of 2021, for a total of 491 compromises, compared to Q1.

https://securityboulevard.com/2021/07/phishing-ransomware-driving-wave-of-data-breaches/

Top CVEs Trending with Cybercriminals

An analysis of criminal forums reveal what publicly known vulnerabilities attackers are most interested in.

Criminal small talk in underground forums offer critical clues about which known Common Vulnerabilities and Exposures (CVEs) threat actors are most focused on. This, in turn, offers defenders clues on what to watch out for.

An analysis of such chatter, by Cognyte, examined 15 cybercrime forums between Jan. 2020 and March 2021. In its report, researchers highlight what CVEs are the most frequently mentioned and try to determine where attackers might strike next.

“Our findings revealed that there is no 100 percent correlation between the two parameters, since the top five CVEs that received the highest number of posts are not exactly the ones that were mentioned on the highest number of Dark Web forums examined,” the report said. “However, it is still enough to understand which CVEs were popular among threat actors on the Dark Web during the time examined.”

Sonicwall Releases Urgent Notice About 'Imminent' Ransomware Targeting Firmware

Networking device maker SonicWall sent out an urgent notice to its customers about "an imminent ransomware campaign using stolen credentials" that is targeting Secure Mobile Access (SMA) 100 series and Secure Remote Access (SRA) products running unpatched and end-of-life 8.x firmware.

In addition to the notice posted to its website, SonicWall sent an email to anyone using SMA and SRA devices, urging some to disconnect their devices immediately. They worked with Mandiant and other security companies on the issue, according to the release.

Google Finds Zero-Day Security Flaws In All Your Favourite Browsers

Researchers at Google have shared insight into four zero-day security vulnerabilities in popular web browsers which were exploited in the wild earlier this year.

DIscovered by Google's Threat Analysis Group (TAG), the four vulnerabilities in Google Chrome, Internet Explorer, and WebKit, the browser engine used by Apple's Safari, were used as a part of three different campaigns.

Top Cyber Stories of the Last Week

Boards Still Aren't Taking Cyber Security Seriously, That Means Everyone Is At Risk

Cyber security still is not taken as seriously as it should be by boardroom executives – and that's leaving organisations open to cyber attacks, data breaches and ransomware, the new boss of the National Cyber Security Centre (NCSC) has warned. In her first speech since taking the helm of the UK cyber security agency, CEO Lindy Cameron said cyber security should be viewed with the same importance to CEOs as finance, legal or any other vital day-to-day part of the enterprise.

https://www.zdnet.com/article/boardrooms-still-arent-taking-cybersecurity-seriously-and-thats-putting-everyone-at-risk-from-attacks-warns-new-ncsc-boss/

Nearly 40% Of New Ransomware Families Use Both Data Encryption And Data Theft In Attacks

2020 saw an explosion of ransomware that also steals data, giving the attackers more leverage over their victims. If organisations first refuse to pay a ransom to decrypt their data, attackers threaten to leak the stolen information, increasing pressure on victims to pay. This evolution, referred to as Ransomware 2.0 in the report, was a significant development in 2020. Only one ransomware group was observed using this type of extortion in 2019. By the end of 2020, 15 different ransomware families had adopted this approach. Furthermore, nearly 40% of ransomware families discovered in 2020, as well as several older families, were known to also steal data from victims by the end of last year.

https://www.helpnetsecurity.com/2021/03/31/ransomware-families-data-encryption/

Ransomware: Why We Are Now Facing A Perfect Storm

Ransomware is becoming more successful than ever before because of a combination of factors that allow cyber criminals to easily gain access to corporate networks – and they are finding success because a significant number of organisations that fall victim to attacks are willing to pay the ransom. A report warns that the 'perfect storm' of conditions have come together and allowed ransomware attacks to run rampant against organisations around the world.

https://www.zdnet.com/article/ransomware-why-were-now-facing-a-perfect-storm/

Ransomware: Nearly A Fifth Of Victims Who Pay Off Extortionists Fail To Get Their Data Back

The poll found that close to half (46%) of UK ransomware victims paid the ransom to restore access to their data last year, yet an unfortunate 11% of victims who shelled out did not have their stolen data returned. Whether they paid or not, only 18% of 1,006 UK victims surveyed were able to restore all their encrypted or blocked files following an attack. Internationally the picture is still worse with more than half (56%) paying off extortionists and nearly one in five of whom (17%) failing to get their data back even after paying out.

https://portswigger.net/daily-swig/ransomware-nearly-a-fifth-of-victims-who-pay-off-extortionists-fail-to-get-their-data-back

Billions Of Records Have Been Hacked Already. Make Cyber Security A Priority Or Risk Disaster

More data records have been compromised in 2020 alone than in the past 15 years combined, in what is described as a mounting "data breach crisis" in the latest study from analysis. Over the past 12 months, 31 billion data records have been compromised. This is up 171% from the previous year and constitutes well over half of the 55 billion data records that have been compromised in total since 2005.

Ransomware Gang Urges Victims’ Customers To Demand A Ransom Payment

A ransomware operation known as 'Clop' is applying maximum pressure on victims by emailing their customers and asking them to demand a ransom payment to protect their privacy. A common tactic used by ransomware operations is to steal unencrypted data before encrypting a victim's network. This data is then used in a double-extortion tactic where they threaten to release the data if a ransom is not paid.

Employee Lockdown Stress May Spark Cyber Security Risk

Stressed-out employees in a remote-working world could be a major contributor to poor cybersecurity postures for companies, according to a survey. Among other findings, the survey found that younger employees as well as people caring for children or other family members reported more stress in their lives, as well riskier IT behaviours when compared to other demographics. For instance, 67 percent of employees under 30 said they use shadow IT (unsanctioned apps, services, and equipment) to help them to perform certain tasks more easily, compared to 27 percent of older workers.

https://threatpost.com/employee-lockdown-stress-cybersecurity-risk/165050/

Shadow IT Is Your Organisation's Next Remote-Working Nightmare

Shadow IT refers to the use of devices, systems and software outside of those permitted by an organisational IT department. According to new research by software company Forcepoint, more than a third (37%) of UK employees are now relying on shadow IT at home, increasing companies' exposure to cyber security risks.

The use of personal devices appears to be one of the biggest culprits: 48% of respondents admitted to using their own devices to access work documents and corporate networks while working from home. Meanwhile, 34% of employees reported using private email or file-sharing cloud services for work purposes – again against the advice of employers.

Top Cyber Stories of the Last Week

‘Really Messy’: Why The Hack of Microsoft’s Email System Is Getting Worse, With Attacks Doubling Every Two Hours

The cyber security community sprang into action after Microsoft first announced a series of vulnerabilities that let hackers break into the company's Exchange email and calendar programs. China has used it to spy on a wide range of industries in the United States ranging from medical research to law firms to defence contractors, the company said. China has denied responsibility. In the past 24 hours, the team has observed "exploitation attempts on organizations doubling every two to three hours." The countries feeling the brunt of attack attempts are Turkey, the United States, and Italy, accounting for 19%, 18%, and 10% of all tracked exploit attempts, respectively.

Cyber Criminals Are Increasingly Targeting Browser Zero Days

As more and more of our work is done within our browsers, cyber criminals have begun to leverage web browser exploits to compromise endpoint systems, according to new research from Menlo Security. At the same time, enterprises around the world were forced to make an almost overnight transition to remote work last year and this surge in employees working from home along with the shift to cloud computing have resulted in a greatly increased attack surface.

https://www.techradar.com/news/cybercriminals-are-increasingly-targeting-browser-zero-days

More Than 1m Small Businesses ‘At Risk Of Collapse’ Due To Cyber Threats

The research, commissioned by Vodafone, also showed that 16 per cent of firms would likely be forced to lay off staff in the event of a hack. As a result, the report called on ministers to beef up the country’s corporate cyber defences, warning that a failure to do so could hamper the post-pandemic economic recovery. It urged the government to expand a dedicated business cyber security within the National Cyber Security Centre (NCSC), which is part of GCHQ, and introduce a five per cent VAT cut on cybersecurity products for small companies.

Number Of Ransomware Attacks Grew By More Than 150%

By the end of 2020, the ransomware market, fueled by the pandemic turbulence, had turned into the biggest cyber crime money artery. Based on the analysis of more than 500 attacks observed during Group-IB’s own incident response engagements and cyber threat intelligence activity, researchers estimate that the number of ransomware attacks grew by more than 150% in 2020.

Top Cyber Stories of the Last Week

New Strain Of Ransomware Implements Self-Spreading Capabilities

French experts spotted a new Ryuk ransomware variant that implements self-spreading capabilities to infect other devices on victims’ local networks.

This new version has a new attribute that allows it to self replicate over the local network allowing the malware to propagate itself – machine to machine – within the Windows domain. Once launched, it will spread itself to every Windows machine it can reach.

https://securityaffairs.co/wordpress/115064/reports/ryuk-ransomware-self-spreading-capabilities.html

One In Four People Use Work Passwords For Consumer Websites

The report found that one in four consumers admit to using their work email or passwords to log in to consumer websites and applications such as food delivery apps, online shopping sites and even dating apps. The report found that consumers are neglecting to implement fundamental security safeguards across smart IoT devices at home, which could have serious security ramifications on both the individual and the enterprise amid increased and ongoing remote work spurred by the COVID-19 pandemic.

https://www.helpnetsecurity.com/2021/02/26/use-work-passwords-for-consumer-websites/

Massive Rise In Threats Across Expanding Attack Surfaces

New malware samples nearly doubled: New ransomware samples increased 106% year-over-year. Trojans increased 128%, with threat actors using trojans to exploit lower-severity vulnerabilities. Sophisticated, multi-staged attacks and malware-as-a-service have become the norm. Vulnerabilities hit a new high: 18,341 new vulnerabilities in 2020 have been reported. To stay ahead of attacks, security and risk leaders need sophisticated insights into which vulnerabilities are high-risk and remediation options for all assets, including non-patching options.

If you discover that a favourite vending-machine dispenses free chocolate when its buttons are pressed just so, what should you do? The virtuous option is to tell the manufacturer, so it can fix it. The temptation is to gorge.

Is Your Browser Extension A Botnet Backdoor?

A company that rents out access to more than 10 million Web browsers so that clients can hide their true Internet addresses has built its network by paying browser extension makers to quietly include its code in their creations. This story examines the lopsided economics of extension development, and why installing an extension can be such a risky proposition.

Cyber Attack Shuts Down Online Learning At 15 UK Schools

A threat actor was able to access the trust's central network infrastructure and while an investigation took place, all existing phone, email, and website communication had to be pulled. Students are still learning remotely in England. Schools are set to reopen on March 8, but in the meantime, only a small subset of children are attending school physically, such as the children of key workers.

First Fully Weaponized Spectre Exploit Discovered Online

A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered and targets Spectre, a major vulnerability that was disclosed in January 2018. According to its website, the Spectre bug is a hardware design flaw in the architectures of Intel, AMD, and ARM processors that allows code running inside bad apps to break the isolation between different applications at the CPU level and then steal sensitive data from other apps running on the same system.

Solarwinds Security Fiasco May Have Started With Simple Password Blunders

We still do not know just how bad the SolarWinds security breach is. We do know over a hundred US government agencies and companies were cracked. "The largest and most sophisticated attack the world has ever seen," with more than a thousand hackers behind it. It may have all started when an intern first set an important password to "'solarwinds123." Then, adding insult to injury, the intern shared the password on GitHub.

Black Arrow Cyber Threat Briefing 18 December 2020

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 Headlines of the Week

The great hack attack: SolarWinds breach exposes big gaps in cyber security

Until this week, SolarWinds was a little known IT software group from Texas. Its deserted lobby has a framed magazine article from a few years ago when it was on a list of America’s “Best Small Companies”.

Now the Austin-based company is at the heart of one of the biggest and most startling cyber hacks in recent history, with ramifications that extend into the fields of geopolitics, espionage and national security.

For nine months, sophisticated state-backed hackers have exploited a ubiquitous SolarWinds software product in order to spy on government and business networks around the world, including in the US, UK, Israel and Canada. Wielding innovative tools and tradecraft, the cyber spies lurked in email services, and posed as legitimate staffers to tap confidential information stored in the cloud.

The bombshell revelations have sent 18,000 exposed SolarWinds customers scrambling to assess whether outsiders did indeed enter their systems, what the damage was and how to fix it.

A wake-up for the world on cyber security

Imagine intruders break into your home and loiter undetected for months, spying on you and deciding which contents to steal. This in essence is the kind of access that hackers, assumed to be Russian, achieved in recent months at US government institutions including the Treasury and departments of commerce and homeland security, and potentially many US companies. If the fear in the Cold War was of occasional “moles” gaining access to secrets, this is akin to a small army of moles burrowing through computer systems. The impact is still being assessed, but it marks one of the biggest security breaches of the digital era.

US government, thousands of businesses now thought to have been affected by SolarWinds security attack

Thousands of businesses and several branches of the US government are now thought to have been affected by the attack on software firm SolarWinds.

The Austin-based company has fallen victim to a massive supply chain attack believed to be the work of state-sponsored hackers.

Along with the US treasury and commerce departments, the Department of Homeland Security is now thought to have been affected by the attack. In a statement to the SEC today, SolarWinds said it had notified 33,000 customers of its recent hack, but that only 18,000 of these used the affected version of its Orion platform.

White House activates cyber emergency response under Obama-era directive

In the wake of the SolarWinds breach, the National Security Council has activated an emergency cyber security process that is intended to help the government plan its response and recovery efforts, according to White House officials and other sources.

The move is a sign of just how seriously the Trump administration is taking the foreign espionage operation, former NSC officials told CyberScoop.

The action is rooted in a presidential directive issued during the Obama administration known as PPD-41, which establishes a Cyber Unified Coordination Group (UCG) that is intended to help the U.S. government coordinate multiple agencies’ responses to the significant hacking incident.

The UCG is generally led by the Department of Justice — through the FBI and the National Cyber Investigative Joint Task Force — as well as the Office of the Director of National Intelligence and the Department of Homeland Security.

Hackers targeted US nuclear weapons agency in massive cyber security breach, reports say

The National Nuclear Security Administration and Energy Department, which safeguard the US stockpile of nuclear weapons, have had their networks hacked as part of the widespread cyber espionage attack on a number of federal agencies.

Politico reports that officials have begun coordinating notifications about the security breach to the relevant congressional oversight bodies.

Suspicious activity was identified in the networks of the Federal Energy Regulatory Commission (FERC), Los Alamos and Sandia national laboratories in New Mexico and Washington, the Office of Secure Transportation, and the Richland Field Office of the Department of Energy.

Officials with direct knowledge of the matter said hackers have been able to do more damage to the network at FERC, according to the report.

Microsoft warns UK companies were targeted by SolarWinds hackers

Microsoft has warned that some of its UK customers have been exposed to the malware used in the Russia-linked SolarWinds hack that targeted US states and government agencies.

More than 40 of the tech giant's customers are thought to have used breached SolarWinds software, including clients in Britain, the US, Canada, Mexico, Belgium, Spain, Israel, and the UAE.

The company would not name the victims, but said they include government agencies, think tanks, non-governmental organisations and IT firms. Microsoft said four in five were in the US, with nearly half of them tech companies.

“This is not ‘espionage as usual,’ even in the digital age,” said Brad Smith, Microsoft's president. “Instead, it represents an act of recklessness that created a serious technological vulnerability for the United States and the world.”

The attackers, believed to be working for the Russian government, got into computer networks by installing a vulnerability in Orion software from SolarWinds.

Society at Increasingly High Risk of Cyber Attacks

Cyber attacks are becoming easier to conduct while conversely security is getting increasingly difficult, according to Kevin Curran, senior IEEE member and professor of cyber security, Ulster University, during a virtual media roundtable.

“Any company you can think of has had a data breach,” he commented. “Whenever a data breach happens it weakens our credentials because our passwords are often reused on different websites.”

He observed that the art of hacking doesn’t necessarily require a significant amount of technical expertise anymore, and bad actors can receive substantial help from numerous and readily accessible tools online. “You don’t have to spend seven years in college to learn how to hack, you just have to know about these sites and what terms to use,” noted Curran.

A number of legitimate online mechanisms that can help damaging attacks to be launched by hackers were highlighted by Curran in his presentation. These include Google Dorks, which are “search strings which point to website vulnerabilities.” This means vulnerable accounts can be identified simply via Google searches.

Three million users installed 28 malicious Chrome or Edge extensions

More than three million internet users are believed to have installed 15 Chrome, and 13 Edge extensions that contain malicious code, security firm Avast said today.

The 28 extensions contained code that could perform several malicious operations, including:

-redirect user traffic to ads

-redirect user traffic to phishing sites

-collect personal data, such as birth dates, email addresses, and active devices

-collect browsing history

-download further malware onto a user's device

But despite the presence of code to power all the above malicious features, Avast researchers said they believe the primary objective of this campaign was to hijack user traffic for monetary gains.

Vaccines for sale on dark web as criminals target pandemic profits

Black market vendors were offering coronavirus vaccines for sale on hidden parts of the internet days after the first Covid-19 shot was approved this month, as criminals seek to profit from global demand for inoculations.

One such offer on the so-called dark web, traced by cyber security company Check Point Software, was priced at $250 with the seller promising “stealth” delivery in double-wrapped packaging. Shipping from the US via post or a leading courier company would cost $20, with an extra $5 securing overnight delivery.
