The ransomware operation known as Alphv - aka BlackCat - appears to be a reboot of the DarkSide group, which rebranded as BlackMatter following serious encryption and victim-selection mistakes. Amid reports that Alphv has disrupted 17 oil terminals in Western Europe, how long until the next rebrand?
A large-scale cyberattack has disrupted operations at oil terminals in Belgium, Germany and the Netherlands with ransomware affecting fuel distribution, oil storage and transport around the world, including Oiltanking in Germany, SEA-Invest in Belgium and Evos in the Netherlands.
Researchers report that because of increased use of multifactor authentication, attackers are developing phishing kits that steal tokens and bypass this trusted layer of security, enabling them to "man in the middle" a browser session and steal credentials and session cookies in real time.
Eset says it has patched a high-severity privilege escalation bug affecting its clients who use Windows-based systems. The company has released software updates for all affected versions of its product, as well as a workaround, and says no exploits have been reported.
Some of the biggest cybercrime-focused darknet markets selling stolen payment card data, passwords, malware and more have retired in the past year, with administrators oftentimes boasting it's because they've gotten rich. As they exit, other players remain ready to grab their market share, experts say.
Four ISMG editors discuss important cybersecurity issues, including misconceptions around Zero Trust implementation, lessons learned from the crippling NotPetya malware attack of 2017 that nearly sank logistics giant Maersk and how a Russian cyberwar in Ukraine could move beyond its borders.
The latest edition of the ISMG Security Report features an analysis of how Russia's escalation in Ukraine is raising cyber defense alarms. It also describes how a Dark Overlord collaborator received a three-year prison sentence and shares tips for Zero Trust implementation.
U.S. DHS Secretary Alejandro Mayorkas confirmed on Thursday that the department is establishing a Cyber Safety Review Board, as directed by President Joe Biden's sweeping cybersecurity executive order signed in May 2021. The board aims to mirror the work of the National Transportation Safety Board.
The Wormhole network, a token bridge that allows users to trade multiple cryptocurrencies without a centralized exchange, has been exploited for 120,000 wETH tokens ($321 million). The company says it has issued a fix for the flaw and is working to "get the network back up as soon as possible."
The security world continues its fight against potential widespread exploitation of the critical remote code execution vulnerability - tracked as CVE-2021-44229 - in Apache's Log4j software library, versions 2.0-beta9 to 2.14.1, known as "Log4Shell" and "Logjam." This is a digest of ISMG's updates.
The Log4j vulnerability exists in unpatched versions of Ubiquiti's UniFi Network applications, and is being actively targeted by attackers via a customized exploit, researchers at security firm Morphisec warn. While updates are available, systems remain at risk until patched.
Russia's threat to Ukraine is reshaping notions of what it means to employ cyber operations as part of a conflict. If Russian military forces do invade, experts warn that cyberattacks meant to support military operations and disrupt critical infrastructure may not be restricted to Ukrainian targets.
In just a month, the BlackCat cybercrime group has carried out high-impact ransomware attacks on international organizations and risen to seventh place in Unit 42's ranking of global ransomware groups. A key factor, researchers say: the use of the Rust language for coding its malware.
