Threats Tagged 'usb worm'

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...

In mid-2025, China-aligned threat actor Hive0154 deployed new malware variants, including an updated Toneshell backdoor and a novel USB worm called SnakeDisk. Toneshell9 evades detection and supports C2 communication through local proxies. SnakeDisk only executes on devices in Thailand, propagating via USB drives and dropping the Yokai backdoor. The malware shows code overlaps with previous Tonedisk variants. Hive0154 continues to refine its large malware arsenal, targeting organizations worldwide with frequent development cycles. The group uses multiple custom loaders, backdoors, and USB worm families, showcasing advanced capabilities. Defenders should monitor for suspicious network activity, USB drives with hidden components, and implement recommended security measures to mitigate risks from this evolving threat.
