Malicious package

salmonnPyPI

Malicious code in salmonn (PyPI) Remove it immediately and rotate any exposed credentials.

MAL-2024-10458
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall salmonn

What this malware does

A campaign of probably pentest packages flooding PYPI. Installing the package or importing the module triggers reporting basic info like hostname, path and the username to the package author. There is no other purpose of the package.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: 2024-11-byted-dast

Reasons (based on the campaign):

  • The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

  • typosquatting

  • dependency-confusion

The OpenSSF Package Analysis project identified 'salmonn' @ 912.6 (pypi) as malicious.

It is considered malicious because:

  • The package communicates with a domain associated with malicious activity.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for salmonn (version 912.6). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging salmonn across your stack and pipelines.

  2. If you installed it — respond

    salmonn 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 salmonn was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks salmonn before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. salmonn on PyPI has been identified as a malicious package (version 912.6 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
