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.

Top Cyber Stories of the Last Week

91% Of IT Teams Have Felt 'Forced' To Trade Security For Business Operations

A new survey suggests that most IT staff have felt pressured to ignore security concerns in favour of business operations. On Thursday, a new study report was released, which combines data from an online YouGov survey targeting office workers that adopted WFH and global research conducted with IT decision-makers. In total, 91% of those surveyed said that they have felt "pressured" to compromise security due to the need for business continuity during the COVID-19 pandemic. 76% of respondents said that security had taken a backseat, and furthermore, 83% believe that working from home has created a "ticking time bomb" for corporate security incidents. https://www.zdnet.com/article/91-of-it-teams-have-felt-forced-to-trade-security-for-business-operations/

Ransomware Attacks Increased Exponentially In 2021

The growing threat of ransomware has been highlighted by NCC Group's Research Intelligence and Fusion Team (RIFT) analysis. Between January-March 2021 and April-June 2021, the number of ransomware assaults studied by the team climbed by 288%, indicating that enterprises are still facing waves of digital extortion in the form of targeted ransomware. https://www.ehackingnews.com/2021/09/ransomware-attacks-increased.html

Phishing Attacks: One In Three Suspect Emails Reported By Employees Really Are Malicious

All the time spent ticking boxes in cyber security training sessions seems to be paying off after all: according to a new report, about a third of emails reported by employees really are malicious or highly suspect, demonstrating the effectiveness of the well-established maxim "Think before you click".  Researchers analysed over 200,000 emails that were flagged by employees from organisations across the globe in the first half of 2021 and found that 33% of the reports could be classified as phishing. https://www.zdnet.com/article/phishing-attacks-one-in-three-suspect-emails-reported-by-employees-really-are-malicious/

Hackers Shift From Malware To Credential Hijacking

Adversaries are relying less on malware to conduct attacks that are consequently more difficult to detect, according to an annual report conducted by researchers. “According to data from our customer base indexed by Threat Graph, 68% of detections from the last three months were not malware-based,” reads the report released Wednesday. “Attackers are increasingly attempting to accomplish their objectives without writing malware to the endpoint, using legitimate credentials and built-in tools (living off the land)—which are deliberate efforts to evade detection by traditional antivirus products.” https://www.nextgov.com/cybersecurity/2021/09/report-hackers-shift-malware-credential-hacking/185209/

Attacker Breakout Time Now Less Than 30 Minutes

The average time it takes threat actors to move from initial access to lateral movement has fallen by 67% over the past year, putting extra pressure on security operations (SecOps) teams, according to researchers. The findings come from researchers own investigations with customers across around 248,000 unique global endpoints. For incidents where this “breakout time” could be derived over the past year, it averaged just 1 hour 32 minutes. However, in over a third (36%) of intrusions, adversaries managed to move laterally to additional hosts in under 30 minutes. https://www.infosecurity-magazine.com/news/attacker-breakout-time-now-less/

Hackers Leak VPN Account Passwords From 87,000 Fortinet FortiGate Devices

Network security solutions provider Fortinet confirmed that a malicious actor had unauthorizedly disclosed VPN login names and passwords associated with 87,000 FortiGate SSL-VPN devices. "These credentials were obtained from systems that remained unpatched at the time of the actor's scan. While they may have since been patched, if the passwords were not reset, they remain vulnerable," the company said in a statement on Wednesday. https://thehackernews.com/2021/09/hackers-leak-vpn-account-passwords-from.html

53% Find It Difficult To Prevent An Insider Attack During Data Aggregation

Recent data from researchers found that 53% of companies find it impossible or very difficult to prevent an insider attack when data is being aggregated, a key indicator of intent of an attack. The vast majority of security threats follow a pattern or sequence of activity leading up to an attack, and insider threats are no exception. To fully understand any insider incident, visibility into the entire kill chain of an attack is imperative to preventing the exfiltration of critical data. https://venturebeat.com/2021/09/02/53-find-it-difficult-to-prevent-an-insider-attack-during-data-aggregation/

The Impact Of Ransomware On Cyber Insurance Driving The Need For Broader Cyber Security Knowledge

Not only have ransomware attacks spiked, the amount of ransom demanded has grown exponentially—to somewhere between $50 and $70 million dollars. Cyber Insurers can’t cover “whatever amount the hacker demands”—so major policies lost money. Insurers have responded by raising premiums, restricting coverage, or even getting out of the cyber-insurance game altogether in vulnerable markets. https://www.helpnetsecurity.com/2021/09/10/cyber-insurance-ransomware/

Hackers Exploit Camera Vulnerabilities To Spy On Parents

Various zero day vulnerabilities in home baby monitor could be compromised that lets threat actors hack into camera feed and put malicious codes like malware. The security issues were found in the IoT gadgets, made by China based developer Victure, that were found by researchers. In a security report, researchers revealed about the stack-based buffer flaw present in ONVIF server Victure PC420 component camera that allows hackers to plant remote codes on the victim device. When compromised, hacker can discover cameras (not owned by them) and command devices to broadcast camera feeds to third party and exploit the camera firmware. https://www.ehackingnews.com/2021/09/hackers-exploit-camera-vulnerabilities.html

39% Of All Internet Traffic Is From Bad Bots

Automated traffic takes up 64% of internet traffic – and whilst just 25% of automated traffic was made up by good bots, such as search engine crawlers and social network bots, 39% of all traffic was from bad bots, a Barracuda report reveals.

These bad bots include both basic web scrapers and attack scripts, as well as advanced persistent bots. These advanced bots try their best to evade standard defences and attempt to perform their malicious activities under the radar. The report revealed that the most common of these persistent bots were ones that went after e-commerce applications and login portals. https://www.helpnetsecurity.com/2021/09/07/bad-bots-internet-traffic/
