Reported Jun 11, 2026 · Updated Jun 12, 2026

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 `import pylogx`, the package spawns a background thread that sleeps 5-20 seconds, force-installs sensitive third-party packages (cryptography, pycryptodomex, secretstorage, opencv-python, pillow, psutil) via pip, then fetches a base64-encoded blob from http://69.164.245.166/payload.txt over plaintext HTTP and passes the decoded bytes to `exec()` with a synthetic `__name__ = "__payload__"`. The destination is a bare IP with no TLS, no pinning, and no signature verification, so any code the operator of that host serves runs in the importing process. The pre-installed dependency set (secretstorage + cryptography) is consistent with a follow-on credential / keyring harvester. The package is also distributed under the name `pylogxo` while installing the import name `pylogx` — a near-edit of legitimate logging library names — and ships placeholder metadata (empty README, `https://github.com/example/pylogx`, `support@pylogx.example`) and references submodules (`formatter`, `handlers`) that do not exist in the tarball, so the module will ImportError only after the dropper thread has already fired. There is no legitimate reason for a logging utility to fetch and execute remote code at import time.

During import, the package downloads and executes remote code being an infostealer.
