The hesk crate version 0.1.0 on crates.io contains malicious code that exfiltrates user data. It includes two asynchronous functions that traverse the user's home directory, archive wallet files, and upload them to a hardcoded Telegram Bot API endpoint. The code is camouflaged with numerous filler functions and uses dependencies enabling cross-platform keylogging and Windows persistence. The crate's description misleadingly claims it is an educational cybersecurity testing project, which contradicts its actual behavior.
