Malicious code in twrap-toolkit (PyPI)

MAL-2026-5841
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall twrap-toolkit

What this malware does

twrap_toolkit/init.py defines _get_payload() which issues a plaintext HTTP request to http://194.5.152.9:8080/hacks/textwrap-toolkit/textwrap_toolkit/__init__.py and passes the response body to exec() inside the package's only public API surface (format_block() and align_columns()). Any caller of the documented API executes attacker-controlled Python with no TLS, no pinning, and no integrity check, granting full remote code execution to the operator of 194.5.152.9. The package name and the attacker-controlled URL path both impersonate the legitimate 'textwrap-toolkit' utility, indicating a typosquat designed to lure installations into the dropper. Installing this package and invoking its advertised functions yields arbitrary code execution as the calling user.

During import, package downloads and executes an obfuscated script. The code then adds a new authorized SSH key and reports back the IP of the current environment. After that, the code also attempts to exfiltrate cryptocurrency wallet data

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for twrap-toolkit (version 1.0.0).

  2. If you installed it — respond

    twrap-toolkit 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 twrap-toolkit 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. twrap-toolkit on PyPI has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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