Russia's invasion of Ukraine continues to have a major impact on energy prices, inflation, and cyberthreats, with the ransomware scene experiencing some of the biggest shifts, according to ESET. "The ongoing war in Ukraine has created a divide among ransomware operators, with some supporting and others opposing the aggression. Attackers have also been using increasingly destructive tactics, such as deploying wipers that mimic ransomware and encrypt the victim's data with no intention of providing a decryption key," explains Roman Kováč, Chief Research Officer at ESET. The digital threats trends. The war also affected brute-force attacks against exposed RDP services, but despite the decline of these attacks in 2022, password guessing remains the most favored network attack vector.
During a webinar called The Hacker Mindset, a Red Team Researcher shared how you can use some of these tools for your own detection and prevention of breaches. The hacker mindset can be characterized by three core values: a strong sense of curiosity, an adversarial attitude, and persistence.
As biometric face verification gains traction and becomes more widely adopted, threat actors are targeting all systems with sophisticated online attacks. To achieve both user friendliness and security, organizations need to evaluate their biometric solutions for resilience in the face of these complex attacks.
CVE-2021-21974 is a vulnerability affecting OpenSLP as used in VMware ESXi. The French government's Computer Emergency Response Team CERT-FR was the first to raise an alert on ransomware exploiting this vulnerability on Feb. 3, 2023, quickly followed by French hosting provider OVH. Attackers can exploit the vulnerability remotely and unauthenticated via port 427, which is a protocol that most VMware customers do not use.
At least 1,200 Redis database servers worldwide have been corralled into a botnet using an "Elusive and severe threat" dubbed HeadCrab since early September 2021. The findings come two months after the cloud security firm shed light on a Go-based malware codenamed Redigo that has been found compromising Redis servers.
The survey found somewhat muted faith in current safety measures, with the 51% saying they are only "Somewhat prepared," 39% feel "Very prepared," 6% feel they are not at all prepared in their overall cyber defense strategies, and 4% are unsure. The survey points to the need for ever-increasing vigilance via employee training and awareness, along with continued investment in system upgrades and staff.
Microsoft revealed today that its security teams are tracking over 100 threat actors deploying ransomware during attacks. In all, the company says it monitors over 50 unique ransomware families that were actively used until the end of last year.
Cybersecurity professionals can avoid drowning in the online data deluge by taking advantage of the host of technical, training and educational resources from the SANS Institute. Launched in 1989 as a cooperative for information security thought leadership, the organisation provides training, certifications, scholarship academies, degree programs, cyber ranges, and pretty much everything else you can think of to meet the needs of cyber professionals.
Currently, the value of generative AI, like ChatGPT and DALL-E, is lopsided in favor of threat actors. Threat actors using generative AI in their attack arsenal is an eventuality, and now we need to focus on how we will defend against this new threat.
Research conducted by Fujitsu suggests there is no need to panic about quantum computers being able to decode encrypted data - this is unlikely to happen in the near future, it claims. Fujitsu said it ran trials using its 39-qubit quantum simulator hardware to assess how difficult it would be for quantum computers to crack data encrypted with the RSA cipher, using a Shor's algorithm approach.
