Malicious `js-logger-pack` versions used an npm `postinstall` script to download cross-platform `MicrosoftSystem64` Node SEA implants from Hugging Face, giving the operator persistent access on Windows, macOS, and Linux. The implant connects to `195.201.194.107:8010`, logs keystrokes, monitors the clipboard, scans for files and secrets, supports arbitrary file operations and payload deployment, and can clear browser sessions to force reauthentication. JFrog found the current stage abuses private Hugging Face datasets as an exfiltration backend, allowing stolen archives to be stored outside the C2 server. The report also documents infrastructure and persona overlaps around `Lordplay`, `whisdev`, `snipmaxi`, and `jrodacooker.dev`, while cautioning that public evidence supports impersonation and infrastructure linkage rather than definitive real-world attribution.
