Malicious package

enhancerPyPI

Advisory published Updated

enhancer is a confirmed malicious PyPI package (MAL-2026-3691) that steals credentials and exfiltrates sensitive data (malicious version 0.2.3). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in enhancer (PyPI)

MAL-2026-3691
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall enhancer

What this malware does

The distribution is published as enhancer but installs modules under the top-level safety namespace (setup.py declares namespace_packages=['safety'] and find_namespace_packages(include=['safety.*']), shipping safety/_python/ and safety/tools/). The real safety package on PyPI (PyUp vulnerability scanner) owns that import path, so any installer code or transitive dependency doing import safety.tools will resolve into attacker-controlled modules. safety/tools/__init__.py actively harvests sensitive values from pyUltroid.configs.Var (API_ID, API_HASH, DETA_KEY, SESSION, VC_SESSION, REDIS_PASSWORD, HEROKU_API, BOT_TOKEN) into a module-level _get_sys dict, then blanks them on the Var object and walks os.environ clearing any variable whose name contains those tokens — destructive mutation of installer state, regardless of whether this specific version includes a network sink. Package metadata is hostile/placeholder (author None, url https://fuckoff.com, description Not For U, README # safety-pip), reinforcing intent to be mistaken for the legitimate safety tool. Three independent block signals: namespace hijack, import-time secret/env mutation, and deceptive metadata.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for enhancer (version 0.2.3).

  2. If you installed it — respond

    enhancer is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If enhancer was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. enhancer on PyPI has been identified as a malicious package (version 0.2.3 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks enhancer-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
