Malicious package

Advisory published Updated

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.

MAL-2026-13711
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
pip uninstall plp-contract

What this malware does

No install-time, import-time, or runtime code paths were identified that read installer secrets, fetch or execute remote code, relay caller data to third-party destinations, or establish persistence. No lifecycle hooks with network I/O and no hardcoded exfiltration endpoints are present.

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.

Campaign: 2026-08-neutrl-core

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

    Search your lockfiles and build artifacts for plp-contract (3 malicious versions).

  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 installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

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.

Detect & block this

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