Top Cyber Stories of the Last Week

Cyber Insurance Firms Start Tapping Out As Ransomware Continues To Rise

In early May, global insurer AXA made a landmark policy decision: The company would stop reimbursing French companies for ransomware payments to cyber criminals. The decision, which reportedly came after French authorities questioned whether the practice had fuelled the current epidemic in ransomware attacks, may be just the beginning of a general retreat that will force companies to reconsider their attempts to outsource cyber-risk to insurance firms. Already, the massive damages from one damaging crypto worm, NotPetya, caused multiple lawsuits when insurers refused to pay out on cyber insurance claims.

Irish Health Service Faces Final Bill Of At Least €100M Following Cyber Attack

The cyber attack on IT systems in the health service will cost it at least €100 million, according to chief executive Paul Reid. This is at the lower end of estimates of the total cost, he indicated, and includes the cost of restoring the network, upgrading systems to Microsoft 365 and the disruption caused to patients. Appointments for about 7,000 patients a day are being cancelled, almost two weeks after a criminal gang hacked the HSE systems. Mr Reid said the HSE was keen to see an independent and objective assessment of the cyber attack.

Ransomware: Dramatic Increase In Attacks Is Causing Harm On A Significant Scale

A dramatic increase in the number of ransomware attacks and their severity is causing harm on a significant scale, the UK's National Crime Agency (NCA) has warned. The NCA's annual National Strategic Assessment (NSA) of Serious and Organised Crime details how the overall threat from cyber crime has increased during the past year, with more severe and high-profile attacks against victims. Ransomware attacks have grown in frequency and impact over the course of the last year, to such an extent that they rank alongside other major crimes "causing harm to our citizens and communities on a significant scale," warns the report.

Deepfakes Could Be The Next Big Security Threat To Businesses

An overwhelming majority of businesses say that manipulated online content and media such as deepfakes are a serious security risk to their organisation. Deepfakes have already been shown to pose a threat to people portrayed in the manipulated videos, and could have serious repercussions when the individual holds a position of importance, be it as a leader of a country, or a leader of an enterprise. Earlier in 2021, the FBI’s cyber division warned that deepfakes are a critical emerging threat that can be used in all manners of social engineering attacks including ones aimed at businesses.

Ransomware: Two-Thirds Of Organisations Say They'll Take Action To Boost Their Defences

The severe disruption caused by the Colonial Pipeline ransomware attack has alerted organisations to the need to bolster their defences against cyber attacks – and two-thirds are set to take actions required to prevent them becoming another ransomware victim following the incident. The ransomware attack against Colonial Pipeline – one of the largest pipeline operators in the United States, providing almost half of the East Coast's fuel – caused disruption to operations and led to gas shortages, demonstrating how cyber attacks can have physical consequences.

The 10 Most Dangerous Cyber Threat Actors

When hacking began many decades ago, it was mostly the work of enthusiasts fuelled by their passion for learning everything they could about computers and networks. Today, nation-state actors are developing increasingly sophisticated cyber espionage tools, while cyber criminals are cashing in millions of dollars targeting everything from Fortune 500 companies to hospitals. Cyber attacks have never been more complex, more profitable, and perhaps even more baffling. At times, drawing clear lines between different kinds of activities is a challenging task. Nation-states sometimes partner with each other for a common goal, and sometimes they even appear to be working in tandem with cyber criminal gangs.

Cyber Security Leaders Lacking Basic Cyber Hygiene

Constella Intelligence released the results of a survey that unlocks the behaviours and tendencies that characterize how vigilant organisations’ leaders are when it comes to reducing cyber vulnerability, allowing the industry to better understand how social media is leveraged as an attack vector and how leaders are responding to this challenge. The findings from the survey, which polled over 100 global cyber security leaders, senior-level to C-suite, across all major industries, including financial services, technology, healthcare, retail, and telecommunications, revealed that 57% have suffered an account takeover (ATO) attack in their personal lives—most frequently through email (52%), followed by LinkedIn (31%) and Facebook (26%).

Watch Out: Crypto Jacking Is On The Rise Again

During the last year, though, malicious crypto mining has seen a resurgence, with NTT’s 2021 Global Threat Intelligence Report, published this month, revealing that crypto miners have now overtaken spyware as the world’s most common malware. Crypto miners, says NTT, made up 41% of all detected malware in 2020, and were most widely found in Europe, the Middle East, Africa, and the Americas. The most common coinminer variant was XMRig, which infects a user’s computer to mine Monero, accounting for 82% of all mining activity. Others included Crypto miner and XMR-Stack.
