The pylever package on PyPI contains malicious code that harvests Discord authentication tokens from local browser and Discord app storage. It scans LevelDB and cache directories of Chrome, Edge, Brave browsers, and Discord's local storage for token patterns, decrypts protected tokens using DPAPI via PowerShell, validates them against the Discord API, and exfiltrates valid tokens and associated user information to a hardcoded Discord webhook URL. The package metadata and README mislead users by suggesting it restores accidentally removed tokens, while it actually performs bulk token harvesting and exfiltration.
