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

MAL-2026-1142
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall wisecloudcyberark

What this malware does

During import, only in specific environments, a module containing code disguised as telemetry is imported. This code then exfiltrates sensitive environment variables and cloud tokens to a hardcoded location, as well as starts a job listening for commands to execute. Likely dependency confusion attempts

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

Reasons (based on the campaign):

  • exfiltration-generic

  • exfiltration-env-variables

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

  • dependency-confusion

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 wisecloudcyberark (version 1.4.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging wisecloudcyberark across your stack and pipelines.

  2. If you installed it — respond

    wisecloudcyberark 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 wisecloudcyberark 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 wisecloudcyberark 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

Detect & block this

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