MAL-2026-4199

ts-logger-pack is a malicious npm package that depends on terminal-logger-utils and triggers the malicious behavior in that package when installed or imported.

The terminal-logger-utils payload executes a postinstall hook that opens utils.cjs, an obfuscated malware dropper. The dropper downloads and runs a platform-specific second-stage binary from Hugging Face. The second-stage payload provides keylogger, infostealer, and RAT behavior, steals sensitive local data including Telegram Desktop sessions, browser login databases, crypto wallets, SSH keys, cloud configurations, environment variables, and keyword-matched files, and connects to a remote server for full machine control.
