Threats Tagged 'trojanized repositories'

Cybercriminals are exploiting the recent Claude Code leak incident by using it as a social engineering tactic to deliver malware through GitHub repositories. The attackers have created trojanized versions of the leaked Claude source code, distributing malicious payloads including Vidar stealer version 18.7 and GhostSocks trojan. The campaign demonstrates rapid opportunistic exploitation of high-profile security incidents, with compromised repositories serving as delivery mechanisms. Organizations are advised to implement Zero Trust architecture to mitigate risks from shadow AI instances and trojanized Claude agents. Multiple GitHub repositories have been identified hosting the malicious code, with command and control infrastructure established across multiple IP addresses and domains.

Banana Squad, a threat actor first identified in 2023, has launched a new campaign targeting GitHub repositories. The group has created over 60 trojanized repositories masquerading as hacking tools written in Python. These malicious repositories contain hundreds of trojanized Python files that utilize encoding and encryption techniques to hide backdoor code. The campaign primarily uses the domain dieserbenni[.]ru, with a new domain 1312services[.]ru detected recently. The trojanized repositories exploit GitHub's UI feature where long lines of code don't wrap, allowing attackers to hide malicious code off-screen. This sophisticated technique makes visual detection challenging, highlighting the increasing stealth of supply chain attacks on open-source platforms.
