Between late July and mid-August 2026, multiple organizations were compromised by a sophisticated modular RAT disguised as a legitimate Exodus cryptocurrency wallet. Victims were tricked through fake PDFs or software updates delivered via JavaScript files that downloaded a tampered Windows Installer package. The installer deploys genuine Exodus wallet version 24.33.4 with three modified files that prevent the user interface from displaying while establishing persistent access. The payload includes six modules providing hidden VNC, SOCKS proxy, browser credential theft, file management, remote shell, and script execution capabilities. Communication occurs via Azure Table Storage as a dead drop mechanism, avoiding traditional command and control domains. The RAT maintains persistence through scheduled tasks executing hourly and includes mechanisms to bypass corporate proxy configurations.

A phishing campaign targets Indian organizations by impersonating the Indian Income Tax Department. Victims receive emails containing links to spoofed notice pages that download ZIP archives. These archives include a legitimately signed Overwolf executable and two hidden files: a malicious DLL and an encrypted binary. When executed, the signed binary side-loads the malicious DLL through DLL hijacking. The DLL is UPX-packed and modified with Astral-PE, and decrypts the binary file containing ValleyRAT. The payload uses modified RC4 encryption with a 115-byte key and deploys entirely in memory. Once active, ValleyRAT establishes persistence through scheduled tasks masquerading as OneDrive entries, marks dropped files as hidden and system files, and performs process hollowing into svchost.exe to evade detection before connecting to command and control infrastructure.
