assulthimarsPyPI

Advisory published Updated

assulthimars is a confirmed malicious PyPI package (MAL-2024-11532) that steals credentials and exfiltrates sensitive data (malicious version 1.3.5). Do not install it — remove it immediately and rotate any exposed credentials.

MAL-2024-11532
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall assulthimars

What this malware does

In the invokehttp, the init.py contains obfuscated code attempting to download and run one of two executables. They are identified as malicious by VT and the tracks of Telegram URLs suggests attempting data exfiltration. The package itself looks like a copy of requests. In flophttp, using exactly the same obfuscation method, the infostealer is directly embeded into package code and exfiltrates data to a telegram channel.

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

Campaign: 2024-08-invokehttp

Reasons (based on the campaign):

  • infostealer

  • Downloads and executes a remote executable.

  • obfuscation

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for assulthimars (version 1.3.5).

  2. If you installed it — respond

    assulthimars 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 assulthimars 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. assulthimars on PyPI has been identified as a malicious package (version 1.3.5 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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