A Windows-based cryptocurrency clipper has been actively targeting users since February 2026, employing sophisticated techniques to steal digital assets. The malware propagates through malicious shortcut files on USB devices, creating a worm-like infection chain. Once deployed, it utilizes Windows Script Host and ActiveX to launch a bundled Tor proxy client, enabling anonymous communication with hidden-service command and control servers. The clipper performs high-frequency clipboard monitoring to intercept cryptocurrency wallet addresses, seed phrases, and private keys, replacing them with attacker-controlled alternatives. Additionally, it captures screenshots for context and maintains persistent access through scheduled tasks. The threat demonstrates advanced capabilities including remote code execution, making it more than a simple stealer by functioning as a lightweight backdoor. The malware employs multiple defense evasion techniques including multi-layer obfuscation, anti-analysis checks, and local S...

A sophisticated phishing campaign distributes a PureLogs variant through deceptive purchase order emails containing malicious JavaScript files. The attack chain employs obfuscated JavaScript that drops PowerShell scripts, which then use process hollowing techniques to inject .NET modules into legitimate Windows processes. The malware communicates with command-and-control infrastructure to download additional plugins. PureLogs collects extensive sensitive information including credentials from web browsers, cryptocurrency wallets, email clients, Discord, and various applications. It also captures screenshots, system information, and clipboard data. The collected data is compressed, encrypted with AES, and exfiltrated to remote servers. The campaign demonstrates advanced evasion techniques through fileless execution, multiple encryption layers, and abuse of trusted processes like MsBuild.exe, making detection challenging for traditional security solutions.
