The SERPENTINE#CLOUD campaign leverages Cloudflare Tunnels and Python-based loaders to deliver memory-injected payloads through a chain of shortcut files and obfuscated scripts. The attack begins with malicious .lnk files disguised as documents, fetching remote code from Cloudflare subdomains. The infection chain involves batch, VBScript, and Python stages, ultimately deploying shellcode that loads a Donut-packed PE payload. The campaign focuses on Western targets, using Cloudflare for payload hosting and anonymity. It demonstrates evolving tactics, shifting from simple .url files to sophisticated .lnk payloads. The final stage involves a RAT payload, giving attackers full control over infected hosts.

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.
