The basek 0.1.0 crate on crates.io is a malicious Rust library functioning as a Windows keylogger. It captures keystrokes including alphanumeric, function, and special keys, and exfiltrates the data to a Telegram Bot API endpoint and a secondary web server. The malware establishes persistence by copying itself to a local appdata directory, creating a Run registry key, spawning a watchdog process to ensure continuous operation, and deleting its original binary. It employs timing delays and randomized polling to evade sandbox and behavioral detection. Although described as an educational cybersecurity project, its obfuscation and persistence mechanisms indicate malicious intent.
