If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On first import, defi_tools/__init__.py decodes a base64-embedded ~486KB Linux ELF, writes it to ~/.config/.npm-cache/snapd-network, sets mode 0777, and installs a user crontab entry (0 */12 * * *) to re-execute it every 12 hours. The binary is disguised under a system-service-like name in a hidden.npm-cache directory that maps to no real npm or snapd path. The init code then recursively removes the package's own dist-info/egg-info and __pycache__ directories, erasing evidence while the dropped binary and cron entry persist.

The package embeds an executable stealing cryptocurrency wallets data. During import, code saves the executable under a name suggesting system utility and configures cron to run it periodically. The exfiltrated data is encrypted using embedded RSA code before uploading to file-sharing services or IPFS.
