Top Cyber Stories of the Last Week

Guernsey Cyber Security Warning for Islanders and Businesses

There has been a rise in cyber-attacks since the war in Ukraine began, according to the States of Guernsey and a cyber-security firm.

The States said: "We have seen a noticeable increase in the number of phishing emails since the war began."

The Channel Islands see more than 10 million cyber attacks every month, according to research by Guernsey firm Black Arrow Cyber Consulting.

It encouraged vigilance, as the islands are not immune to these attacks.

A States spokesman said: "The whole community needs to remain vigilant against such emails, which are designed to appear to be from reputable sources in order to dupe people into providing personal information or access to their device via the clicking of a link."

Bruce McDougall, from Black Arrow Cyber Consulting, said: "Criminals don't let a good opportunity go to waste. So they're conducting scams encouraging people to make false payments in the belief they're collecting for charities."

CISOs Face 'Perfect Storm' Of Ransomware and State-Supported Cyber Crime

As some nations turn a blind eye, defence becomes life-or-death matter

With ransomware gangs raiding network after network, and nation states consciously turning a blind eye to it, today's chief information security officers are caught in a "perfect storm," says Cybereason CSO Sam Curry.

"There's this marriage right now of financially motivated cyber crime that can have a critical infrastructure and economic impact," Curry said during a CISO roundtable hosted by his endpoint security shop. "And there are some nation states that do what we call state-ignored sanctioning," he continued, using Russia-based REvil and Conti ransomware groups as examples of criminal operations that benefit from their home governments looking the other way. 

"You get the umbrella of sovereignty, and you get the free license to be a privateer in essence," Curry said. "It's not just an economic threat. It's not just a geopolitical threat. It's a perfect storm."

It's probably not a huge surprise to anyone that destructive cyber attacks keep CISOs awake at night. But as chief information security officers across industries — in addition to Curry, the four others on the roundtable spanned retail, biopharmaceuticals, electronics manufacturing, and a cruise line — have watched threats evolve and criminal gangs mature, it becomes a battle to see who can innovate faster; the attackers or the defenders.

Four Key Risks Exacerbated by Russia’s Invasion of Ukraine

Russia’s invasion of Ukraine has altered the emerging risk landscape, and it requires enterprise risk management (ERM) leaders to reassess previously established organisational risk profiles in at least four key areas, according to Gartner.

“Russia’s invasion of Ukraine has increased the velocity of many risks we have tracked on a quarterly basis in our Emerging Risks survey,” said Matt Shinkman, VP with the Gartner Risk and Audit Practice.

“As ERM leaders reassess their organisational risk models, they must also ensure a high frequency of communication with the C-Suite as to the critical changes that require attention now.”

There are four major areas of risk that ERM leaders should continually monitor and examine their mitigation strategies as part of a broader aligned assurance approach as the war continues: Talent Risk, Cyber Security Risk, Financial Risk and Supply Chain Risk

These Four Types of Ransomware Make Up Nearly Three-Quarters of Reported Incidents

Any ransomware is a cyber security issue, but some strains are having more of an impact than others.

Ransomware causes problems no matter what brand it is, but some forms are noticeably more prolific than others, with four strains of the malware accounting for a combined total of almost 70% of all attacks.

According to analysis by cyber security company Intel 471, the most prevalent ransomware threat towards the end of 2021 was LockBit 2.0, which accounted for 29.7% of all reported incidents. Recent victims of LockBit have included Accenture and the French Ministry of Justice. 

Almost one in five reported incidents involved Conti ransomware, famous for several incidents over the past year, including an attack against the Irish Healthcare Executive. The group recently had chat logs leaked, providing insights into how a ransomware gang works. PYSA and Hive account for one in 10 reported ransomware attacks each.

"The most prevalent ransomware strain in the fourth quarter of 2021 was LockBit 2.0, which was responsible for 29.7% of all reported incidents, followed by Conti at 19%, PYSA at 10.5% and Hive at 10.1%," said the researchers.

Critical Infrastructure Threat as Ransomware Groups Target 'Enemies of Russia'

The cyber crime underground has fractured into pro-Ukraine and pro-Russia camps, with the latter increasingly focused on critical national infrastructure (CNI) targets in the West, according to a new report from Accenture.

The consulting giant’s Accenture Cyber Threat Intelligence (ACTI) arm warned that the ideological schism could spell mounting risk for Western organisations as pro-Kremlin criminal groups adopt quasi-hacktivist tactics to choose their next victims.

Organisations in the government, media, finance, insurance, utilities and resources sectors should be braced for more attacks, said ACTI.

Cyber Insurance War Exclusions Loom Amid Ukraine Crisis

An expanding threat landscape is testing the limits of cyber insurance coverage.

The industry experienced a rapid maturation over the past three years as enterprises required a broader umbrella of insurance coverage to combat increasing cyber risks. While demands and premiums continue to rise, one recent area of contention involves war and hostile acts, an exclusion that's becoming harder to categorize.

A judgment in December, coupled with the Russian invasion last month that posed potential cyber retaliations to Ukraine allies, highlighted shortcomings in insurance policies when it comes to cyber conflicts.

Zelenskyy Deepfake Crude, But Still Might Be a Harbinger of Dangers Ahead

Several deepfake video experts called a doctored video of Ukrainian President Volodymyr Zelenskyy that went viral this week before social media platforms removed it a poorly executed example of the form, but nonetheless damaging.

Elements of the Zelenskyy deepfake — which purported to show him calling for surrender — made it easy to debunk, they said. But that won’t always be the case.

Cyber Crooks’ Political In-Fighting Threatens the West

They’re choosing sides in the Russia-Ukraine war, beckoning previously shunned ransomware groups and thereby reinvigorating those groups’ once-diminished power.

A rift has formed in the cyber crime underground: one that could strengthen, rather than cripple, the cyber-onslaught of ransomware.

According to a report, ever since the outbreak of war in Ukraine, “previously coexisting, financially motivated threat actors divided along ideological factions.”

“Pro-Ukrainian actors are refusing to sell, buy, or collaborate with Russian-aligned actors, and are increasingly attempting to target Russian entities in support of Ukraine,” wrote researchers from Accenture’s Cyber Threat Intelligence (ACTI). “However, pro-Russian actors are increasingly aligning with hacktivist-like activity targeting ‘enemies of Russia,’ especially Western entities due to their claims of Western warmongering.”

What might otherwise seem like a good thing – bad guys fighting bad guys – may in fact pose an increased threat to the West.

Cloud-Based Email Threats Surge 50% in 2021

There was a 50% year-on-year surge in cloud-based email threats in 2021, but a drop in ransomware and business email compromise (BEC) detections as attacks became more targeted, according to Trend Micro.

The security vendor’s 2021 roundup report, Navigating New Frontiers, was compiled from data collected by customer-installed products and cloud-based threat intelligence.

It revealed that Trend Micro blocked 25.7 million email threats targeting Google Workspace and Microsoft 365 users last year, versus 16.7 million in 2020.

The number of phishing attempts almost doubled during the period, as threat actors continued to target home workers. Of these, 38% were focused on stealing credentials, the report claimed.

Millions of New Mobile Malware Strains Blitzed Enterprise in 2021

Researchers uncovered more than two million new mobile malware samples in the wild last year, Zimperium said in a new report.

Those threats spanned some 10 million mobile devices in at least 214 countries, the Dallas, Texas-based solution provider said in its newly released 2022 Global Mobile Threat Report. Indeed, mobile malware proved in 2021 to be the most prevalent security threat to enterprises, encountered by nearly 25 percent mobile endpoints among Zimperium’s customers worldwide. The 2.3 million new mobile strains Zimperium’s researchers located amount to nearly 36,000 new strains of malware weekly and roughly 5,000 each day.

UK Criminal Defence Lawyer Hadn't Patched When Ransomware Hit

Criminal defence law firm Tuckers Solicitors is facing a fine from the UK's data watchdog for failing to properly secure data that included information on case proceedings which was scooped up in a ransomware attack in 2020.

The London-based business was handed a £98,000 penalty notice by the Information Commissioner's Office under Article 83 of the EU's General Data Protection Regulation 2018.

The breach was first noted by Tuckers on August 23 2020 when part of its IT system became unavailable. On closer inspection, resident techies found a note from the attackers confirming they had compromised part of the infrastructure. The Microsoft Exchange server was out of action and two days' worth of emails were lost, as detailed by the company blog at the time.

Russian Ransomware Gang Retool Custom Hacking Tools of Other APT Groups

A Russian-speaking ransomware outfit likely targeted an unnamed entity in the gambling and gaming sector in Europe and Central America by repurposing custom tools developed by other APT groups like Iran's MuddyWater, new research has found.

The unusual attack chain involved the abuse of stolen credentials to gain unauthorized access to the victim network, ultimately leading to the deployment of Cobalt Strike payloads on compromised assets, said Felipe Duarte and Ido Naor, researchers at Israeli incident response firm Security Joes, in a report published last week.

Although the infection was contained at this stage, the researchers characterized the compromise as a case of a suspected ransomware attack.

The intrusion is said to have taken place in February 2022, with the attackers making use of post-exploitation tools such as ADFind, NetScan, SoftPerfect, and LaZagne. Also employed is an AccountRestore executable to brute-force administrator credentials and a forked version of a reverse tunneling tool called Ligolo.

The Massive Impact of Vulnerabilities in Critical Infrastructure

Recent cyber events have shown how extremely vulnerable critical infrastructure is. What are the biggest security concerns?

In any world conflict, one of the primary threats posed is cyber actors disabling or destroying the core infrastructure of the adversary. Based on the global reaction to the current world conflict, countries fear reprisals. The worry is that there will be collateral damage to the critical infrastructure of other countries not directly involved in the current conflict.

Today, services such as healthcare systems, power grids, transportation and other critical industries are increasingly integrating their operational technology with traditional IT systems in order to modernize their infrastructure, and this has opened up a new wave of cyber attacks. Though businesses are ramping up their security initiatives and investments to defend and protect, their efforts have largely been siloed, reactive, and lack business context. Lack of visibility of risk across the estate is a huge problem for this sector.
