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

Businesses Suffered 50% More Cyber Attack Attempts per Week in 2021

Cyberattack attempts reached an all-time high in the fourth quarter of 2021, jumping to 925 a week per organisation, partly due to attempts stemming from the Log4j vulnerability, according to new data.

Check Point Research on Monday reported that it found 50% more attack attempts per week on corporate networks globally in calendar year 2021 compared with 2020.

The researchers define a cyberattack attempt as a single isolated cyber occurrence that could be at any point in the attack chain — scanning/exploiting vulnerabilities, sending phishing emails, malicious website access, malicious file downloads (from Web/email), second-stage downloads, and command-and-control communications.

Cyber Attacks Against MSPs Jump 67%

Cyber attacks spiked by 50 percent in 2021 as compared to 2020, aided by millions of attacks in December by hackers attempting to exploit the Log4J vulnerability, according to a Check Point Software Technologies research report.

In terming 2021 a “record breaking year,” the security provider pointed to a worldwide peak of 925 cyber attacks per organisation weekly and an October 2021 measure that showed a 40 percent increase in cyberattacks, with one out of every 61 entities hit by ransomware each week. The number of cyberattacks on managed service providers (MSPs) and internet service providers (ISPs) rose by nearly 70 percent year over year.

SMEs Still An Easy Target For Cyber Criminals

Cyber crime continues to be a major concern, with 51% of SMEs experiencing a cyber security breach, a Markel Direct survey reveals.

In this survey that polled 1000 respondents, Markel Direct explored the issue of cybercrime and its impact on the self-employed and SMEs. The survey found the most common cybersecurity attacks were malware/virus related (24%) followed by a data breach (16%) and phishing attack (15%), with 68% reporting the cost of their breach was up to £5,000.

This comes after the latest Quarterly Fraud and Cyber Crime Report revealed that Britons lost over £1 billion in the first six months of 2021, due to the considerable increase in fraudulent activity.

World Economic Forum: Cyber Security Failures an Increasing Global Threat

Cybersecurity was once again identified as a major short and medium-term threat to the world in this year’s World Economic Forum’s (WEF’s) The Global Risk Report. The analysis was based on insights from nearly 1000 global experts and leaders who responded to the WEF’s Global Risks Perception Survey (GRPS).

Perhaps unsurprisingly, environmental issues like climate action failure and extreme weather ranked highest on the risks facing the world over the short (0-2 years), medium (2-5 years) and long-term (5-10 years). In addition, a number of challenges exacerbated by the pandemic, such as livelihood crises, infectious diseases and mental health deterioration, also scored highly. Overall, this added up to a pessimistic assessment, with 84.2% of respondents stating they were either “worried” or “concerned” about the global outlook.

Digital challenges, such as “cyber security failures,” were also viewed as a significant and growing problem to the world. Nearly one in five (19.5%) respondents believe cybersecurity failures will be a critical threat to the world in just the next 0-2 years, and 14.6% said it would be in 2-5 years

Russia Arrests REvil Ransomware Gang Responsible for High-Profile Cyber Attacks

In an unprecedented move, Russia's Federal Security Service (FSB), the country's principal security agency, on Friday disclosed that it arrested several members belonging to the notorious REvil ransomware gang and neutralized its operations.

The surprise takedown, which it said was carried out at the request of the US authorities, saw the law enforcement agency conduct raids at 25 addresses in the cities of Moscow, St. Petersburg, Moscow, Leningrad and Lipetsk regions that belonged to 14 suspected members of the organised cyber crime syndicate.

"In order to implement the criminal plan, these persons developed malicious software, organised the theft of funds from the bank accounts of foreign citizens and their cashing, including through the purchase of expensive goods on the Internet," the FSB said in a statement.

In addition, the FSB seized over 426 million rubles, including in cryptocurrency, $600,000, €500,000, as well as computer equipment, crypto wallets used to commit crimes, and 20 luxury cars that were purchased with money obtained by illicit means.

North Korea Hackers Stole $400m Of Cryptocurrency In 2021, Report Says

North Korean hackers stole almost $400m (£291m) worth of digital assets in at least seven attacks on cryptocurrency platforms last year, a report claims.

Blockchain analysis company Chainalysis said it was one of most successful years on record for cyber-criminals in the closed east Asian state.

The attacks mainly targeted investment firms and centralised exchanges.

North Korea has routinely denied being involved in hack attacks attributed to them.

"From 2020 to 2021, the number of North Korean-linked hacks jumped from four to seven, and the value extracted from these hacks grew by 40%," Chainalysis said in a report.

No Lights, No Heat, No Money - That's Life In Ukraine During Cyber Warfare

Hackers who defaced and interrupted access to numerous Ukrainian government websites on Friday could be setting the stage for more serious cyberattacks that would disrupt the lives of ordinary Ukrainians, experts said.

"As tensions grow, we can expect more aggressive cyber activity in Ukraine and potentially elsewhere," said John Hultquist, an intelligence analyst at US cyber security company Mandiant, possibly including "destructive attacks that target critical infrastructure."

"Organisations need to begin preparing," Hultquist added.

Intrusions by hackers on hospitals, power utility companies, and the financial system were until recently rare. But organised cyber criminals, many of them living in Russia, have gone after institutions aggressively in the past two years with ransomware, freezing data and computerized equipment needed to care for hospital patients.

In some cases, those extortion attacks have led to patient deaths, according to litigation, media reports and medical professionals.

Ukrainian Police Arrest Five Members Of Ransomware Affiliate

Ukrainian police announced the arrest of five members of a ransomware affiliate on Thursday, noting that the group was behind attacks on more than 50 companies across Europe and the US.

In a statement, both the Ukrainian Security Service and Ukrainian Cyber Police said the group made at least $1 million through their attacks on the companies.

US and UK law enforcement officials worked with Ukrainian officials on the operation.

Officials said the leader of the group was a 36-year-old who worked with his wife and three other people out of Kyiv. The five are facing a variety of charges in Ukraine related to money laundering, hacking, and selling malware.

One of the people charged is wanted by law enforcement agencies in UK after "using a virus to obtain bank card details of the customers of British banks," according to the police statement.

The bank card details were used to buy things online that were then resold.

Fingers Point To Lazarus, Cobalt, Fin7 As Key Hacking Groups Attacking Finance Industry

The Lazarus, Cobalt, and FIN7 hacking groups have been labeled as the most prevalent threat actors striking financial organisations today.

According to "Follow the Money," a new report (.PDF) published on the financial sector by Outpost24's Blueliv on Thursday, members of these groups are the major culprits of theft and fraud in the industry today.

The financial sector has always been, and possibly always will be, a key target for cybercriminal groups. Organisations in this area are often custodians of sensitive personally identifiable information (PII) belonging to customers and clients, financial accounts, and cash.

They also often underpin the economy: if a payment processor or bank's systems go down due to malware, this can cause irreparable harm not only to the victim company in question, but this can also have severe financial and operational consequences for customers.

Ransomware, Supply Chain, And Deepfakes: The Top Threats The Finance Industry Needs To Prepare For

The finance industry is constantly targeted by numerous threat actors, and they are always innovating and trying new techniques (such as deepfakes) to outsmart security teams and breach an organisation’s network.

In addition to that, there is currently a huge demand for data and new tools on the dark web. In fact, users are selling access to point-of-sale (PoS) terminals and login details to the websites of financial services organisations all the time.

How can financial organisations protect themselves from existing threats and combat new ones at the same time?

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

Microsoft Sees Rampant Log4j Exploit Attempts, Testing

Microsoft says it’s only going to get worse: It’s seen state-sponsored and cyber-criminal attackers probing systems for the Log4Shell flaw through the end of December.

No surprise here: The holidays bought no Log4Shell relief.

Threat actors vigorously launched exploit attempts and testing during the last weeks of December, Microsoft said on Monday, in the latest update to its landing page and guidance around the flaws in Apache’s Log4j logging library.

“We have observed many existing attackers adding exploits of these vulnerabilities in their existing malware kits and tactics, from coin miners to hands-on-keyboard attacks,” according to Microsoft.

https://threatpost.com/microsoft-rampant-log4j-exploits-testing/177358/

Warning: Log4j Still Lurks Where Dependency Analysis Can’t Find It

The best programming practice to include a third-party library in source code is to use the import command. It is the easiest way to do it, and it is also the way that most dependency analysis programs work to determine if a vulnerable library is in play. But any time code is included without calling it as an external package, traditional dependency analysis might not be enough to find it — including when Java coders use a common trick to resolve conflicting dependencies during the design process.

A new study by jFrog found that 400 packages on repository Maven Central used Log4j code without calling it as an external package. Around a third of that came from fat jars — jar files that include all external dependencies to make a more efficient product. The remainder came from directly inserting Log4j code into the source code, including shading, a work-around used when two or more dependencies call different versions of the same library in a way that might conflict.

While 400 may not seem like a lot for Maven Central, where Google found 17,000 packages implementing the vulnerable Log4j library, some of the 400 packages unearthed by JFrog are widely used.

Hackers Sending Malware-Filled USB Sticks to Companies Disguised as Presents

The "malicious USB stick" trick is old but apparently it's still wildly popular with the crooks.

Word to the wise: If a stranger ever offers you a random USB stick as a gift, best not to take it.

On Thursday, the FBI warned that a hacker group has been using the US mail to send malware-laden USB drives to companies in the defence, transportation and insurance industries. The criminals’ hope is that employees will be gullible enough to stick them into their computers, thus creating the opportunity for ransomware attacks or the deployment of other malicious software, The Record reports.

The hacker group behind this bad behaviour—a group called FIN7—has gone to great lengths to make their parcels appear innocuous. In some cases, packages were dressed up as if they were sent by the US Department of Health and Human Services, with notes explaining that the drives contained important information about COVID-19 guidelines. In other cases, they were delivered as if they had been sent via Amazon, along with a “decorative gift box containing a fraudulent thank you letter, counterfeit gift card, and a USB,” according to the FBI warning.

Patch Systems Vulnerable To Critical Log4j Flaws, UK And US Officials Warn

One of the highest-severity vulnerabilities in years, Log4Shell remains under attack.

Criminals are actively exploiting the high-severity Log4Shell vulnerability on servers running VMware Horizon in an attempt to install malware that allows them to gain full control of affected systems, the UK’s publicly funded healthcare system is warning.

CVE-2021-44228 is one of the most severe vulnerabilities to come to light in the past few years. It resides in Log4J, a system-logging code library used in thousands if not millions of third-party applications and websites. That means there is a huge base of vulnerable systems. Additionally, the vulnerability is extremely easy to exploit and allows attackers to install Web shells, which provide a command window for executing highly privileged commands on hacked servers.

The remote-code execution flaw in Log4J came to light in December after exploit code was released before a patch was available. Malicious hackers quickly began actively exploiting CVE-2021-44228 to compromise sensitive systems.

‘Elephant Beetle’ Lurks For Months In Networks

The group blends into an environment before loading up trivial, thickly stacked, fraudulent financial transactions too tiny to be noticed but adding up to millions of dollars.

Researchers have identified a threat group that’s been quietly siphoning off millions of dollars from financial- and commerce-sector companies, spending months patiently studying their targets’ financial systems and slipping in fraudulent transactions amongst regular activity.

The Sygnia Incident Response team has been tracking the group, which it named Elephant Beetle, aka TG2003, for two years.

In a Wednesday report, the researchers called Elephant Beetle’s attack relentless, as the group has hidden “in plain sight” without the need to develop exploits.

Sonicwall: Y2k22 Bug Hits Email Security, Firewall Products

SonicWall has confirmed today that some of its Email Security and firewall products have been hit by the Y2K22 bug, causing message log updates and junk box failures starting with January 1st, 2022.

The company says that email users and administrators will no longer be able to access the junk box or un-junk newly received emails on affected systems.

They will also no longer be able to trace incoming/outgoing emails using the message logs because they're no longer updated.

On January 2nd, SonicWall deployed updates to North American and European instances of Hosted Email Security, the company's cloud email security service.

It also released fixes for its on-premises Email Security Appliance (ES 10.0.15) and customers using firewalls with the Anti-Spam Junk Store functionality toggled on (Junk Store 7.6.9).

Hackers Use Video Player To Steal Credit Cards From Over 100 Sites

Hackers used a cloud video hosting service to perform a supply chain attack on over one hundred real estate sites that injected malicious scripts to steal information inputted in website forms.

These scripts are known as skimmers or formjackers and are commonly injected into hacked websites to steal sensitive information entered into forms. Skimmers are commonly used on checkout pages for online stores to steal payment information.

In a new supply chain attack discovered by Palo Alto Networks Unit42, threat actors abused a cloud video hosting feature to inject skimmer code into a video player. When a website embeds that player, it embeds the malicious script, causing the site to become infected.

Cyber World Is Starting 2022 In Crisis Mode With The Log4j Bug

The cyber security world is starting off 2022 in crisis mode.

The newest culprit is the log4j software bug, which cyber security and Infrastructure Security Agency (CISA) Director Jen Easterly called “the most serious vulnerability I have seen in my decades-long career.” It forced many cyber security pros to work through the holidays to protect computer systems at Big Tech firms, large and small companies and government agencies.

But crises like log4j have become the norm rather than the exception during the past few years.

Last year kicked off with the SolarWinds hack — a Russian government operation that compromised reams of sensitive information from U.S. government agencies and corporations.

Digital threats of all sorts are growing far faster than the capability to defend against them. If past is prologue, 2022 is likely to be a year of big hacks, big threats and plenty more crises.

“We’re always in crisis is the long and short of it,” Jake Williams, a former National Security Agency (NSA) cyber operator and founder of the firm Rendition Infosec, told me. “Anyone looking for calm rather than the storm in cyber is in the wrong field.”

Everything You Need To Know About Ransomware Attacks and Gangs In 2022

Ransomware is a lucrative business for criminals. It is paying off, and it is working.

According to a recent Trend Micro report, a staggering 84% of US organisations experienced either a phishing or ransomware attack in the last year. The average ransomware payment was over $500,000.

Bad actors want to keep cashing in. So they’re going as far as creating ransomware kits as a service (Ransomware as a Service) to be sold on the dark web and even setting up fake companies to recruit potential employees.

Many ransomware gangs function like real companies — with marketing teams, websites, software development, user documentation, support forums and media relations.

If the “companies” run by ransomware gangs can operate with minimal expenses and mind-blowing revenues, what’s stopping them from growing in number and size?

Why the Log4j Vulnerability Makes Endpoint Visibility and Zero Trust Security More Important Than Ever

The Apache Log4j vulnerability is one of the most serious vulnerabilities in recent years—putting millions of devices at risk.

IT organisations worldwide are still reeling from the discovery of a major security vulnerability in Apache Log4j, an open-source logging utility embedded in countless internal and commercial applications.

By submitting a carefully constructed variable string to log4j, attackers can take control of any application that includes log4j. Suddenly, cyber criminals around the world have a blueprint for launching attacks on everything from retail store kiosks to mission-critical applications in hospitals.

If security teams overlook even one instance of log4j in their software, they give attackers an opportunity to issue system commands at will. Attackers can use those commands to install ransomware, exfiltrate data, shut down operations — the list goes on.

How should enterprises respond to this pervasive threat?
