Which versions of pyphetools are malicious?

The following PyPI versions of pyphetools are flagged malicious: 0.9.120. Treat any of these as compromised.

How do I remediate pyphetools if I installed it?

Remove pyphetools from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is pyphetools part of a known attack campaign?

Yes — pyphetools is associated with the 2026-06-compr-woodpecker campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect pyphetools in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking pyphetools and packages like it before any post-install script runs.

What this malware does

The package pyphetools version 0.9.120 contains a malicious .pth file (pyphetools-setup.pth) that executes a Bun-based credential stealer on every Python startup via CPython's site.py exec() mechanism. The payload downloads the Bun runtime from the official GitHub release page, then runs an obfuscated JavaScript stealer that exfiltrates environment variables, .env files, SSH keys, and cloud credentials to an attacker-controlled GitHub repository. This is part of the Hades/Miasma campaign (also called Shai-Hulud), attributed to the TeamPCP threat actor.

Novel finding: gpsea/_index.js (same campaign) embeds CBRN-level dangerous-content text to trigger AI safety refusals in LLM-based security scanners, causing them to skip the file entirely.

Versions 0.9.120 were compromised.

Compromised packages start an obfuscated infostealer. The infostealer is a heavily obfuscated JavaScript code executed using Bun runtime on Python startup. It collectes all kinds of sensitive data, including API keys, credentials to package repositories, cryptocurrency assets, password manager data. Infostealer actively queries online services to collect additional secrets as well as attempts to gain persistence and spread further by publishing infected packages using collected credentials. Data are exfiltrated likely using Github. The code seems to threaten to wipe the user's data if it detects invalid GitHub tokens. Cleanup should be done with caution.

It seems to be related to the recent Mini Shai Hulud campaign.

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