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

Employees Think They’re Safe From Cyber Threats On Company Devices

A research launched by Menlo Security reveals increased cyber security risks posed to employees and organisations during the 2021 holiday shopping season.

The research – which surveyed 2,000 employed people in the United States and the United Kingdom – found that while employees are concerned about threats and are taking some measures to mitigate them, they often have false confidence in their security posture.

There are now more threats to corporate devices and networks than ever as hybrid work models blur the boundaries between work and home. More than half of respondents (56% US; 53% UK) reported performing non-work-related tasks – such as online shopping – on company devices.

Furthermore, the survey found that 65% of people in the US (63% UK) are doing more online holiday shopping in 2021 compared to previous years, and nearly half of respondents (48% US; 45% UK), reported shopping for gifts this holiday season on a work-issued device such as a laptop or mobile phone.

Workers are also noticing a rise in cyber threats this holiday season, with 58% of respondents in the US (48% UK) observing an increase in scams and fraudulent messages, exemplifying that threats are rampant worldwide. This is worrying many people, as the vast majority of respondents (80% US & UK) report being somewhat to very concerned about their personal data being stolen while online shopping.

However, despite workers’ recognition and concern of cyber threats, 60% of people (65% UK) still believe they’re secure from cyberthreats if they’re using a company device.

Internet Is Scrambling To Fix Log4shell, The Worst Hack In History

Massive data breaches have become so common that we’ve gotten numb to reports detailing another hack or 0-day exploit. That doesn’t reduce the risk of such events happening, as the cat-and-mouse game between security experts and hackers continues. As some vulnerabilities get fixed, others pop up requiring attention from product and service providers. The newest one has a name that will not mean anything to most people. They call the hack Log4Shell in security briefings, which doesn’t sound very scary. But the new 0-day attack is so significant that some people see it as the worst internet hack in history.

Malicious individuals are already exploiting the Log4Shell attack, which allows them to get into computer systems and servers without a password. Security experts have seen Log4Shell in action in Minecraft, the popular game that Microsoft owns. A few lines of text passed around in a chat might be enough to penetrate the defences of a target computer. The same ease of access would allow hackers to go after any computer out there using the Log4J open-sourced java-based logging utility.

Apache Log4j Flaw: A Fukushima Moment for the Cyber Security Industry

Organisations around the world will be dealing with the long-tail consequences of this vulnerability, known as Log4Shell, for years to come.

The discovery of a critical flaw in the Apache Log4j software is nothing short of a Fukushima moment for the cybersecurity industry.

Ten years ago, an earthquake and subsequent tidal wave triggered the meltdown of the Fukushima nuclear power plant that continues to plague the region today. Similarly, the early exploitation of Log4j, during which attackers will go after the low-hanging fruit exposed by the vulnerability, will evolve over time to take the form of more complex attacks on more sensitive systems that have less exposure to the internet. And, just as Fukushima brought to light significant issues with longstanding processes in place at the plant, so too does the Log4j vulnerability, known as Log4Shell, highlight two crucial practices of concern:

·       How organisations capture and protect their massive troves of log data; and

·       The use of open-source code libraries as the building blocks for major enterprise applications.

The paradox of Log4j: the more you log, the worse it gets

We’re discovering new apps every minute which use Log4j in one way or another. It affects not only the code you build, but also the third-party systems you have in place. Everything from the new printer you’ve bought for the office to the ticketing system you’ve just deployed is potentially affected by this flaw. Some affected systems may be on premises, others may be hosted in the cloud but no matter where they are, the flaw is likely to have an impact.

60% of UK Workers Have Been Victim of a Cyber-Attack, Yet Awareness Remains Low

There is a “dangerous” lack of awareness among UK workers towards cybersecurity, leaving businesses at risk of attacks, according to a new study by Armis. This is despite 60% of workers admitting they have fallen victim to a cyber-attack.

The nationwide survey of 2000 UK employees found that only around a quarter (27%) are aware of the associated cyber risks, while one in 10 (11%) don’t worry about them at all.

Even more worryingly, just one in five people said they paid for online security, putting businesses at high risk of attacks amid the shift to remote working during COVID-19.

The most prevalent types of attacks experienced by workers or their organisations were phishing (27%), data breaches (23%) and malware (20%).

The study also revealed growing concerns about the scale of the cyber-threats facing the UK. A large-scale cyber-attack was ranked as the fourth biggest future concern (21%) among the respondents, equal to the UK going to war. Two-fifths (40%) said they would like to see a minister for cyber security installed to ensure the issue is focused on more at a government level.

Russian-backed cyber-criminals were considered the biggest threat to the UK’s cybersecurity (20%) by the respondents, followed by financially motivated cyber-criminals (17%) and Chinese-backed cyber-criminals (16%).

Ransomware in 2022: We're All Screwed

Ransomware is now a primary threat for businesses, and with the past year or so considered the "golden era" for operators, cybersecurity experts believe this criminal enterprise will reach new heights in the future.

Kronos. Colonial Pipeline. JBS. Kaseya. These are only a handful of 2021's high-profile victims of threat groups including DarkSide, REvil, and BlackMatter.

According to Kela's analysis of dark web forum activity, the "perfect" prospective ransomware victim in the US will have a minimum annual revenue of $100 million and preferred access purchases include domain admin rights, as well as entry into Remote Desktop Protocol (RDP) and Virtual Private Network (VPN) services.

Over the past few years, we've seen ransomware operators evolve from disorganised splinter groups and individuals to highly sophisticated operations, with separate teams collaborating to target everything from SMBs to software supply chains.

Ransomware infection is no longer an end goal of a cyberattack. Instead, malware families in this arena -- including WannaCry, NotPetya, Ryuk, Cerber, and Cryptolocker -- can be one component of attacks designed to elicit a blackmail payment from a victim organisation.

Attacks on UK Firms Increase Five-Fold During Pandemic

Attacks on UK firms surged five-fold during the pandemic and now cost way more than the global average, according to Accenture.

The global consultancy polled 500 UK executives to compile its State of Cybersecurity Resilience 2021 study.

It found that large organisations experienced 885 attempted cyber-attacks in 2020 – up from 156 the previous year and more than triple the global average of 270.

They’re also more expensive than elsewhere. Accenture calculated that incidents and breaches cost over £1.3m a year – £350,000 more than the global average.

Over 80% of respondents said the cost of staying ahead of cyber-criminals is unsustainable, a fifth more than the previous year, and a quarter said they’ve been forced to increase cybersecurity budgets by 10% or more.

Worryingly, supply chain attacks accounted for 64% of breaches in the UK last year, up by a quarter (26%) from the previous year.

The Log4J Software Flaw Is ‘Christmas Come Early’ for Cyber Criminals

Researchers have just identified a security flaw in a software program called Log4J, widely used by a host of private, commercial and government entities to record details ranging from usernames and passwords to credit card transactions. Since the glitch was found last weekend, the cybersecurity community has been scrambling to protect applications, services, infrastructure and even Internet of Things devices from criminals—who are already taking advantage of the vulnerability.

“For cybercriminals this is Christmas come early, because the sky’s the limit,” says Theresa Payton, a former White House chief information officer and the CEO of Fortalice Solutions, a cybersecurity consulting company. “They’re really only limited by their imagination, their technical know-how and their own ability to exploit this flaw.” Payton spoke with Scientific American about what Log4J does, how criminals can use its newly discovered weakness, and what it will take to repair the problem.

Why Cloud Storage Isn't Immune to Ransomware

Ransomware is the flavour of the month for cybercriminals. The FBI reports that ransomware attacks rose 20% and losses almost tripled in 2020. And our increased use of the cloud may have played a part in that spike. A survey of CISOs conducted by IDC earlier this year found that 98% of their companies suffered at least one cloud data breach in the previous 18 months as opposed to 79% last year, and numbers got worse the more exposure they had to the cloud.

Organisations now use hundreds of cloud-based apps, which adds thousands of new identities logging in to their systems. This opens almost unlimited possibilities for hackers. Even if cloud vendors have their own identity and access management controls, vulnerabilities will emerge. In fact, recent research into cloud security found that over 70% of organisations had machines open to the public that were linked to identities whose permissions were vulnerable, under the right conditions, to being exploited to launch ransomware attacks.

A number of reasons could explain why security falls through the cracks of many cloud systems, and leaves them more vulnerable to ransomware attacks.

400 Banks’ Customers Targeted with Anubis Trojan

Customers of Chase, Wells Fargo, Bank of America and Capital One, along with nearly 400 other financial institutions, are being targeted by a malicious app disguised to look like the official account management platform for French telecom company Orange S.A.

Researchers say this is just the beginning.

Once downloaded, the malware – a variant of banking trojan Anubis – steals the user’s personal data to rip them off, researchers at Lookout warned in a new report. And it’s not just customers of big banks at risk, the researchers added: Virtual payment platforms and crypto wallets are also being targeted.

“As a banking trojan malware, Anubis’ goal is to collect significant data about the victim from their mobile device for financial gain,” the Lookout report said. “This is done by intercepting SMSs, keylogging, file exfiltration, screen monitoring, GPS data collection and abuse of the device’s accessibility services.”

Sites Hacked With Credit Card Stealers Undetected For Months

Threat actors are gearing up for the holidays with credit card skimming attacks remaining undetected for months as payment information is stolen from customers.

Magecart skimming is an attack that involves the injection of malicious JavaScript code on a target website, which runs when the visitor is at the checkout page.

The code can steal payment details such as credit card number, holder name, addresses, and CVV, and send them to the actor.

Threat actors may then use this information for purchasing goods online or sold to other actors on underground forums and dark web marketplaces known as "carding" sites.

Black Arrow Cyber Threat Briefing 30 July 2021: Many Workers Ignore Security Risks To Maximize Productivity; Financial Services Accounting For Nearly 40% Of All Phishing URLs; Half Of Organisations Are Ineffective At Countering Phishing And Ransomware Threats; 36% Of Organisations Suffered A Serious Cloud Security Data Leak Or A Breach In The Past Year; HP Finds 75% Of Threats Were Delivered By Email In First Six Months Of 2021

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

Many Workers Ignore Security Risks To Maximize Productivity

A large proportion of employees often take shortcuts to optimize productivity at work, despite understanding the security risks, new data suggests. According to a survey which polled 8,000 workers worldwide, almost four in five (79%) have engaged in one or more “risky activity” in the past twelve months. In a third of cases (35%), this involved saving passwords to their browser. A similar percentage admitted to using a single password across multiple online accounts, while 23% connected personal devices to corporate networks.

Financial Services Accounting For Nearly 40% Of All Phishing URLs

A report was released for H1 2021, which revealed that there has been a major jump in phishing attacks since the start of the year with a 281 percent spike in May and another 284 percent increase in June, for a total of 4.2 billion phishing emails detected for June alone. For this 6-month window researchers identified Crédit Agricole as the most impersonated brand, with 17,555 unique phishing URLs, followed by Facebook, with 17,338, and Microsoft, with 12,777.

Half Of Organisations Are Ineffective At Countering Phishing And Ransomware Threats

Half of organisations are not effective at countering phishing and ransomware threats. The findings come from a study compiled from interviews with 130 cyber security professionals in mid-sized and large organisations. “Phishing and ransomware were already critical enterprise security risks even before the pandemic hit and, as this report shows, the advent of mass remote working has increased the pressure of these threats,”. “Organisations need multi-layered defences in place to mitigate these risks.”

36% Of Organisations Suffered A Serious Cloud Security Data Leak Or A Breach In The Past Year

As cloud adoption accelerates and the scale of cloud environments grows, engineering and security teams say that risks—and the costs of addressing them—are increasing. The findings are part of the State of Cloud Security 2021 survey. The survey of 300 cloud pros (including cloud engineers; security engineers; DevOps; architects) found that 36% of organisations suffered a serious cloud security data leak or a breach in the past 12 months, and eight out of ten are worried that they’re vulnerable to a major data breach related to cloud misconfiguration. 64% say the problem will get worse or remain unchanged over the next year.

HP Finds 75% Of Threats Were Delivered By Email In First Six Months Of 2021

According to the latest HP Report, email is still the most popular way for malware and other threats to be delivered, with more than 75% of threats being sent through email messages.  The report -- covering the first half of 2021 -- is compiled based on customers who opt to share their threat alerts with the company. HP's researchers found that there has been a 65% rise in the use of hacking tools downloaded from underground forums and filesharing websites from H2 2020 to H1 2021. Some of the tools can solve CAPTCHA challenges using computer vision techniques.

Data Breach Costs Hit Record High Due To Pandemic

Data breaches have always proved costly for victimized organisations. But the coronavirus pandemic made a bad situation even worse. A report released Wednesday looks at how and why the average cost of dealing with a data breach has jumped to a new high. The average cost of a data breach among companies surveyed reached $4.24 million per incident, the highest in 17 years.

Top 30 Critical Security Vulnerabilities Most Exploited By Hackers

Intelligence agencies in Australia, the U.K., and the U.S. issued a joint advisory on Wednesday detailing the most exploited vulnerabilities in 2020 and 2021, once again demonstrating how threat actors can swiftly weaponize publicly disclosed flaws to their advantage. The top 30 vulnerabilities span a wide range of software, including remote work, virtual private networks (VPNs), and cloud-based technologies, that cover a broad spectrum of products from Microsoft, VMware, Pulse Secure, Fortinet, Accellion, Citrix, F5 Big IP, Atlassian, and Drupal.

Average Time To Fix High Severity Vulnerabilities Grows From 197 Days To 246 Days In 6 Months: Report

A recent report has found that the remediation rate for severe vulnerabilities is on the decline, while the average time to fix is on the rise. The report, which is compiled monthly, covers window of exposure, vulnerability by class and time to fix. The latest report found that the window of exposure for applications has increased over the last six months while the top-5 vulnerability classes by prevalence remain constant, which the researchers behind the report said was a "systematic failure to address these well-known vulnerabilities." According to researchers, the time to fix vulnerabilities has dropped 3 days, from 205 days to 202 days. The average time to fix is 202 days, the report found, representing an increase from 197 days at the beginning of the year. The average time to fix for high vulnerabilities grew from 194 days at the beginning of the year to 246 days at the end of June.

Why Remote Working Leaves Us Vulnerable To Cyber Attacks

An industry survey found 56% of senior IT technicians believe their employees have picked up bad cyber security habits while working from home. For Example. A cyber-crime group known as REvil took meticulous care when picking the timing for its most recent attack - US Independence Day, 4 July. They knew many IT specialists and cyber-security experts would be on leave, enjoying a long weekend off work. Before long, more than 1,000 companies in the US, and at least 17 other countries, were under attack from hackers. Many firms were forced into a costly downtime period as a result. Among those targeted during the incident was a well-known software provider, Kaseya. REvil used Kaseya as a conduit to spread its ransomware - a malware that can scramble and steal an organisation's computer data - through other corporate and cloud-based networks that use the software.

Stop Mitigating Cyber Security Threats And Start Preventing Them

The impacts of a successful cyber attack can be devastating. Through multiple forms of extortion, criminals can use stolen data and other business-critical assets, including sensitive financial and customer data to hold companies hostage with just one campaign. The average cost of a phishing attack last year was $832,500, with zero-day attacks costing around $1,238,000. Spending this amount of money to recover from a cyber attack could bring a company to its knees. Today’s cyber attacks present very real existential threats to businesses and C-level executives are beginning to fully realize the gravity of these threats. It is critical that organizations invest in solutions that are going to help stop these attackers before they enter their environments.
