What this malware does

Packages that seem to be created by a legit bug bounty hunter. Designed to look like created by different organisations, they contain a couple of data exfiltration (including all env variables) and potential remote code execution (though the URL seems not to serve any code).

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

Campaign: 2025-05-sl4x01

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.

  • exfiltration-env-variables

  • impersonation

The OpenSSF Package Analysis project identified 'document-inference' @ 0.0.2 (pypi) as malicious.

It is considered malicious because:

  • The package executes one or more commands associated with malicious behavior.

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 document-inference (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging document-inference across your stack and pipelines.

  2. If you installed it — respond

    document-inference 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 document-inference 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 document-inference 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. document-inference on PyPI has been identified as a malicious package (versions 0.0.0, 0.0.1, 0.0.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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