Malicious package

rehttpsPyPI

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

MAL-2025-6575
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall rehttps

What this malware does

During installation, package attempts to download and starts an executable. The package itself is a clone of requests

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

Campaign: 2025-06-rehttps

Reasons (based on the campaign):

  • clones-real-package

  • The package overrides the install command in setup.py to execute malicious code during installation.

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 rehttps (2 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging rehttps across your stack and pipelines.

  2. If you installed it — respond

    rehttps 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 rehttps 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 rehttps 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. rehttps on PyPI has been identified as a malicious package (versions 2.32.3, 2.32.4 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

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