Written By Black Arrow Admin

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

  • Ransomware Attacks Surged to New Highs in 2021

Ransomware attacks are getting more frequent, more successful and more expensive.

Sixty-six percent of the organisations surveyed by Sophos for its annual State of Ransomware report admitted that they were hit with a ransomware attack last year, up from 37% in 2020. And 65 percent of those attacks were successful in encrypting their victims' data, up from 54 percent the year before.

On top of that, the average ransom paid by organisations for their most significant ransomware attack grew by nearly five times, to just over $800,000, while the number of organisations that paid ransoms of $1 million or more tripled to 11%, the UK-based cybersecurity company said. For its annual report, Sophos surveyed 5,600 organisations from 31 countries. A total of 965 of those polled shared details of their ransomware attacks.

The numbers aren't a huge surprise after a year of epic ransomware attacks that shut down everything from a major oil pipeline to one of the largest meat processors in the US. While both Colonial Pipeline and JBS US Holdings paid millions in ransom, the attacks paused their operations long enough to spark panic buying and drive prices up for consumers.

  • NCSC and Allies Publish Advisory on The Most Commonly Exploited Vulnerabilities In 2021

The UK and international partners have published an advisory for public and private sector organisations on the 15 most commonly exploited vulnerabilities in 2021.

The National Cyber Security Centre (NCSC), a part of GCHQ, has jointly published an advisory with agencies in the US, Australia, Canada and New Zealand, showing that malicious cyber actors aggressively targeted newly disclosed critical software vulnerabilities across the public and private sectors worldwide.

Threat actors often geared their efforts towards targeting internet-facing systems, such as email and virtual private network (VPN) servers.

It also indicates that, to a lesser extent, actors continue to exploit publicly known – and often dated – vulnerabilities, some of which were routinely exploited in 2020 or earlier.

The advisory directs organisations to follow specific mitigation advice to protect against exploitation, which includes applying timely patches, using a centralised patch management system and replacing any software no longer supported by the vendor.

  •  Network Attacks Increased to a 3-Year High

WatchGuard Technologies’ Internet Security Report for Q4 2021 revealed all threats were up, whether they’re network attacks or malware.

When the pandemic started, their research team saw a big drop in malware being detected by network security devices. In this period, tech based jobs moved to remote work, which meant a lot of users were no longer browsing the internet and encountering bad things through the network security control at the office. That’s probably why network detection for malware dropped quite a bit at the beginning of the pandemic.

Meanwhile, network attacks continued to rise even through the pandemic, since the servers still lived at the offices and the cloud, and network security still protected those.

The big takeaway in Q4 2021 is that malware rose significantly, returning to normal levels. The reason might be the holiday season, but it’s most probably the fact that, at the end of last year, a lot of tech-based offices started reopening and offering employees to come back in, and thus there’s a bigger chance for network security controls to catch malware.

  • World War Three Is Far More Likely Than Anyone Is Prepared to Admit

A Telegraph article looks at the Russia-Ukraine conflict and considers risks posed by new weapons and how the West’s failure to understand our enemies are raising the chances of a horrific conflict.

The fact is the world is becoming more, rather than less, dangerous: there are plenty of other wannabe Putins, and they are better equipped to sow death and destruction. Not only traditional and nuclear threats but bioterrorism is a growing worry and a major cyber attack or assault on transatlantic cables could be so devastating to an internet-based economy as to be seen as a declaration of war.

  • The Ransomware Crisis Deepens, While Data Recovery Stalls

Higher probabilities of attack, soaring ransoms, and less chance of getting data back — the ransomware plague gets worse, and cyber insurance fails to be a panacea.

When it comes to ransomware, more companies are seeing attacks and have had data encrypted, according to research out this week. And even though more companies are backing up or paying ransom demands, less data was recovered in 2021 compared with the previous year.

For instance, in its "State of Ransomware 2022" report, cybersecurity firm Sophos found that 66% of surveyed companies had encountered ransomware in 2021, with two-thirds of those firms — or 43% overall — suffering from an actual attack that encrypted data. In its previous report covering 2020, the frequency of successful attacks was much smaller, with about 20% overall resulting in encryption.

The deteriorating cyberthreat landscape is largely due to the evolution of ransomware groups and their techniques, says Sean Gallagher, senior threat researcher with Sophos.

"Over the past couple of years, there has been a massive transition from ransomware to ransomware-as-a-service," he says. "There are very well-established [groups] that are doing these attacks, and as a result, the number of attacks companies are seeing has gone up."

Ransomware continues to plague companies with business-disrupting attacks and defy efforts by cybersecurity experts to rein in the operators behind the criminals’ campaigns. Not only did the portion of companies affected by ransomware more than double last year, but the mean ransomware payment more than quadrupled to $812,000, according to the Sophos report.

  • Ransoms Only Make Up 15% of Ransomware Costs

New research suggests that paying ransoms is only the tip of the cost iceberg when it comes to ransomware attacks.

Researchers at Check Point have revealed that the collateral damage of ransomware attacks make up costs roughly seven times higher than the ransom demanded by threat actors.

The costs include financial implications caused by incident response efforts, system restoration, legal fees, monitoring costs and the overall impact of business disruption.

Ransomware attacks are an increasingly popular attack method, typically involving stealing data from the victim, encrypting data and forcing them to pay for decryption and avoiding a data leak.

Check Point said in the report:

“Most other losses, including response and restoration costs, legal fees, monitoring costs, etc., are applied whether the extortion demand was paid or not. The year 2020 showed that the average total cost of a ransomware attack was more than seven times higher than the average ransom paid.”

  • Defending Your Business Against Russian Cyber Warfare

We are likely to see Russian state sponsored attacks escalate as the West continues to increase sanctions and support Ukraine.

The eyes of the world are focused on the war in Ukraine. As expected, Russia has targeted Ukraine with cyber attacks first, and much of the West is wondering when Russia will also retaliate against countries supporting Ukraine. Most agree that some attacks are already in progress, and the attacks against western entities are sure to escalate as the war continues and more sanctions are put in place. 

The first wave of companies targeted by the Russian state, and threat actors it supports, will be those that suspend Russian operations or take direct action to support Ukraine. Information operations and subversion against these companies will likely ensue. In the event of Russian cyberwarfare, reviewing the industries, styles, and objectives of their attacks can help organisations to prepare and implement more robust defences. These defences include actions both inside and outside an enterprise's perimeter.

  • 5-Year Vulnerability Trends Are Both Surprising and Sadly Predictable

What 5,800+ pentests show us: Companies have been struggling with the same known and preventable security bugs year over year. Bandwidth stands at the heart of the problem.

Cyber crime can cause major disruption when it comes to the sustainability and long-term success of companies. Teams want to have robust security but often struggle to meet that objective. It's crucial for security professionals to leverage insights into emerging trends in cybersecurity to pinpoint which vulnerabilities put organisations at the greatest risk, and Cobalt's "State of Pentesting" reports explore how to achieve efficiency to strengthen security.

The "State of Pentesting 2022" surveyed 602 cybersecurity and software development professionals and analysed data from 2,380 pentests conducted over the course of 2021 to pull key insights that are relevant to security and development teams when it comes to fixing vulnerabilities.

As a result of the data collected, the top five most common vulnerability categories outlined in this year's "State of Pentesting" report include:

·       Server Security Misconfigurations

·       Cross-Site Scripting (XSS)

·       Broken Access Control

·       Sensitive Data Exposure

·       Authentication and Sessions

Surprisingly — yet predictably — these vulnerability categories have stayed at the top of the list for at least the last five years in a row. They're also recognisable to those who are familiar with OWASP Top 10 list for Web Application Security Risks.

The majority of these findings are connected to missing configurations, outdated software, and a lack of access management controls — all common and easily preventable security flaws. So, what's holding companies back from preventing well-known security flaws? Why does this come as a surprise?

  • Cisco Talos Observes 'Novel Increase' in APT Activity in Q1

Advanced persistent threat actors have been busy over the past few months, according to Cisco Talos.

The security vendor released its Quarterly Trends report, which examined incident response trends from engagements in the first quarter of 2022. While ransomware remained the top threat, as it has for the past two years now, Cisco observed a new trend of increased APT activity. The Cisco Talos Incident Response (CTIR) team attributed some of the increase to groups like Iranian state-sponsored Muddywater and China-based Mustang Panda.

One suspected Chinese APT, dubbed "Deep Panda," was connected to exploitation of the Log4j flaw that was discovered last year in the widely used Java logging tool. Log4j exploitation was the second most common threat for Q1 behind ransomware, indicating the bug is a growing threat despite a patch being available.

  • Deepfakes Set to Be Used in Organised Crime

New research from Europol suggests that deepfakes will be used extensively in organised crime operations.

Europol has warned of a projected rise in the use of deepfake technology by organised crime organisations.

Deepfakes involve the use of artificial intelligence to create realistic audio and audio-visual content “that convincingly shows people saying or doing things they never did, or create personas that never existed in the first place.”

Law enforcement and the challenge of deepfakes is the first published analysis of the Europol Innovation Lab’s Observatory function, warning that law enforcement agencies must rapidly improve skills and technologies utilised by officers in order to keep up with criminal deepfake use.

The analysis report highlighted how deepfakes are used primarily in disinformation, non-consensual pornography and document fraud campaigns, which will grow more realistic in years to come.

  • Smart Contract Developers Not Really Focused on Security. Who Knew?

"Smart contracts," which consist of self-executing code on a blockchain, are not nearly as smart as the label suggests.

They are at least as error-prone as any other software, where historically the error rate has been about one bug per hundred lines of code.

And they may be shoddier still due to disinterest in security among smart contract developers, and perhaps inadequate technical resources.

Multi-million dollar losses attributed to smart contract bugs – around $31m stolen from MonoX via smart contract exploit and ~$34m locked into a contract forever due to bad increment math, to name a few – illustrate the consequences.

  • Tractor-Trailer Brake Controllers Vulnerable to Remote Hacker Attacks

We’ve been predicting this for a while now and the move to more and more connected systems, autonomous and semi-autonomous vehicles, how long until someone is subject to threats to disconnect a vehicle’s brakes as they are driving along a motorway? Who wouldn’t pay the ransom demand in that scenario?

A report this week is related to articulated lorries but this is something that will be affecting all vehicles unless safeguards are put in place.

Researchers have analysed the cyber security of heavy vehicles and discovered that the brake controllers found on many tractor-trailers in North America are susceptible to remote hacker attacks.

The research was conducted by the US National Motor Freight Traffic Association (NMFTA), which is a non-profit organisation that represents roughly 500 motor freight carriers, in collaboration with Assured Information Security, Inc.

NMFTA has been analysing the cyber security of heavy vehicles since 2015 and it has periodically disclosed its findings. The latest report from the organisation came in early March, when the US Cybersecurity and Infrastructure Security Agency (CISA) also issued an advisory to describe two vulnerabilities affecting trailer brake controllers.

The flaws described in the CISA advisory are related to the power line communications (PLC) between tractors and trailers, specifically the PLC4TRUCKS technology, which uses a standard named J2497 for bidirectional communications between the tractor and trailer without adding new wires.
