A suspected TeamPCP-linked supply chain attack compromised multiple SAP CAP and Cloud MTA npm packages by injecting malicious preinstall scripts. The attack leverages a downloaded Bun runtime to execute an obfuscated payload that harvests extensive credentials from developer machines and CI/CD pipelines, exfiltrating data via attacker-controlled GitHub repositories and establishing persistence through VSCode and Claude AI configurations.
Following an accidental source code leak of Anthropic's Claude Code via npm, threat actors rapidly deployed fake GitHub repositories to distribute a Rust-compiled dropper. This dropper, part of a broader rotating-lure campaign, deploys Vidar stealer and GhostSocks proxy while utilizing extensive anti-analysis checks and PowerShell to disable Windows Defender.
Following an accidental leak of Anthropic's Claude Code source material, threat actors rapidly deployed a social engineering campaign using fake GitHub repositories. The campaign distributes trojanized archives containing a Rust-compiled dropper that deploys Vidar stealer and GhostSocks proxy malware, specifically targeting developers seeking AI tools.
Elastic Security Labs identified a financially motivated operation dubbed REF1695 that distributes RATs and cryptominers via fake installer ISOs. The threat actor monetizes infections through Monero mining and CPA fraud, utilizing advanced evasion techniques like Themida packing, dynamic analysis tool detection, and a novel .NET implant named CNB Bot.
Storm-2561 is conducting a credential theft campaign leveraging SEO poisoning to distribute fake enterprise VPN clients. The attack utilizes digitally signed payloads and DLL side-loading to deploy the Hyrax infostealer, which harvests VPN credentials and configuration data before redirecting victims to legitimate software to evade detection.
