Description

Researchers have identified a new Windows-based cryptocurrency clipper malware active since February 2026 that combines clipboard hijacking, credential theft, and remote code execution capabilities. The malware is primarily distributed through malicious .LNK shortcut files propagated via USB drives. When executed, the shortcut launches a worm component that hides legitimate documents, creates deceptive shortcut files, and installs obfuscated JavaScript payloads. The malware relies heavily on Windows Script Host (WScript) and ActiveXObject functionality to execute commands, collect system information, and launch hidden processes. Instead of using traditional command-and-control infrastructure, it bundles a portable Tor client and routes all communications through a local SOCKS5 proxy on localhost:9050, concealing network activity. Once active, the malware monitors the clipboard every few hundred milliseconds for cryptocurrency wallet addresses, seed phrases, and private keys. Stolen addresses are replaced with attacker-controlled wallet addresses, allowing cryptocurrency theft during transactions. A notable feature of the malware is its ability to receive and execute attacker-supplied JavaScript code through an EVAL command, effectively transforming the clipper into a lightweight backdoor capable of remote code execution. The malware also captures screenshots, uploads sensitive information through Tor-based hidden services, and spreads to newly connected removable drives. Microsoft Defender detects the threat as Trojan:Win32/CryptoBandits.A. Disabling AutoRun, restricting script interpreters, and blocking .LNK execution from removable media can significantly reduce exposure.
