Submission + - Hackers Abuse Blockchain Smart Contracts to Spread Malware (WordPress) (thehackernews.com)
bleedingobvious writes: A financially motivated threat actor codenamed UNC5142 has been observed abusing blockchain smart contracts as a way to facilitate the distribution of information stealers, such as Atomic (AMOS), Lumma, Rhadamanthys (aka RADTHIEF), and Vidar, targeting both Windows and Apple macOS systems.
"UNC5142 is characterized by its use of compromised WordPress websites and 'EtherHiding,' a technique used to obscure malicious code or data by placing it on a public blockchain, such as the BNB Smart Chain," Google Threat Intelligence Group (GTIG) said in a report shared with The Hacker News.
As of June 2025, Google said it flagged about 14,000 web pages containing injected JavaScript that exhibit behavior associated with an UNC5142, indicating indiscriminate targeting of vulnerable WordPress sites. However, the tech giant noted that it has not spotted any UNC5142 activity since July 23, 2025, either signaling a pause or an operational pivot.
