Source: amazon-inspector (6720ca3891de59548dfdfc9b6af778b5bf97fb31c5188381c73e92c4ac2820e1)

The package's _Client class scans Chrome, Edge, and Brave browser profile LevelDB and Cache directories and the Discord Desktop app's Roaming/discord Local Storage/leveldb for strings matching the Discord token regexes [MN][A-Za-z0-9_-]{71} and mfa\.[...]{84}, decrypts protected values via DPAPI invoked through PowerShell, validates each candidate against the Discord API, and POSTs valid tokens along with the associated username, id, email, verified flag, and bot flag to a hardcoded Discord webhook at https://discord.com/api/webhooks/1547416857537945601/.... _DataFinder.find_all() additionally walks the caller-supplied workspace path recursively and matches the same token regex against file contents, sending matches to the same webhook. The webhook URL is a module-level constant assigned in _Client.__init__ with no API surface to override it, despite the README claiming the user configures the webhook. Package metadata uses placeholder values (author="Your Name", your.email@example.com, github.com/yourusername/pylever) and the README frames the tool as restoring accidentally removed tokens, contradicting the actual bulk-harvest and exfiltration behavior.

The package contains a stealer exfiltrating Discord tokens to a hardcoded location.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
