Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall textwrap-toolkit

What this malware does

During installation, obfuscated code exfiltrates cryptocurrency wallet data to a hardcoded location and places a backdoor through a new authorized SSH key. Information about the placed backdoor is sent back to the attacker, and sshd configuration is adjusted to ensure the successful remote connection.

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

Campaign: 2026-05-ninja-core-utils

Reasons (based on the campaign):

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

  • obfuscation

  • crypto-related

  • exfiltration-crypto

  • backdoor

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 textwrap-toolkit (version 1.2.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging textwrap-toolkit across your stack and pipelines.

  2. If you installed it — respond

    textwrap-toolkit 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 textwrap-toolkit 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 textwrap-toolkit 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
