Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall devtools-webhook-cicd-utils

What this malware does

During installation, package installs a script that listens for remote commands and executes them. The script is also added to autostart configuration and disguised as system application

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

Campaign: 2026-02-devtools-webhook-cicd-utils

Reasons (based on the campaign):

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

  • peristence-autorun

  • The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.

  • obfuscation

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 devtools-webhook-cicd-utils (4 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging devtools-webhook-cicd-utils across your stack and pipelines.

  2. If you installed it — respond

    devtools-webhook-cicd-utils 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 devtools-webhook-cicd-utils 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 devtools-webhook-cicd-utils 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.
