Between May and July 2026, researchers tracked the Latin America-focused threat actor Blind Eagle through multiple exposed staging servers, identifying significant toolkit evolution. Four key developments emerged: a third string-obfuscation scheme featuring JavaScript with custom AES S-box substitution, a RunPE loader using bare AutoIt3 interpreter staged via GitHub, a reusable 'Photo Studio' persistence mechanism shared across three distinct toolchains, and a materially upgraded AsyncRAT variant codenamed JC-46. This enhanced RAT incorporates Windows Notification Facility process injection, custom Base28 encoding, Hidden VNC banking-fraud capabilities with browser profile cloning, and a Chrome App-Bound Encryption v20 bypass. Despite operational security weaknesses including exposed directories and hardcoded credentials, the group demonstrates selective sophistication targeting banking operations across Spanish-speaking regions.
