Malicious package

plp-contractPyPI

plp-contract is a confirmed malicious PyPI package (MAL-2026-13711) that steals credentials and exfiltrates sensitive data (malicious versions 2.0.0, 2.0.1, 2.0.2). Do not install it — remove it immediately and rotate any exposed credentials.

Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall plp-contract

What this malware does

This package intentionally depends on a malicious package.

This campaign exfiltrates sensitive environment variables, SSH keys, dotenv files and other credentials. The malicious code is hidden in a dependency package (e.g. neutrl-core) in a function disguised as telemetry, and requires activates once the attacker-controlled endpoint delivers the command. While the user can provide their blockchain endpoints, the code makes sure the malicious endpoint is always included in the configuration. In analyzed versions, the dependent packages did not use the malicious code but were clearly prepared for the supply chain attack. The related GitHub account faked the activity by publishing repositories with backdated commits (the account was created after any of the commits).

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

Reasons (based on the campaign):

  • files-exfiltration

  • exfiltration-env-variables

  • exfiltration-ssh-keys

  • crypto-related

  • action-hidden-in-lib-usage

  • The malicious code is intentionally included in a dependency of the package

  • exfiltration-crypto

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

  • exfiltration-credentials

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 plp-contract (3 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging plp-contract across your stack and pipelines.

  2. If you installed it — respond

    plp-contract 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 plp-contract 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 plp-contract 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. plp-contract on PyPI has been identified as a malicious package (versions 2.0.0, 2.0.1, 2.0.2 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
