Advisory
MAL-2026-18205
Source
OpenSSF Malicious Packages via OSV
Summary
Malicious code in @tekmidian/pai (npm)
Details
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Independent LPM AI assessment
Manual ReviewIndependent AI assessment: manual_review. LPM AI review remains unresolved.
The scanner’s credential-redirection and reverse-shell claims are not demonstrated by the inspected excerpts, but the package’s agent integration and several flagged runtime paths remain unresolved. Manual review is appropriate because the available inspection does not support a reliable clean or malicious verdict.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Unresolved; the reviewed source does not establish an attack trigger.
Impact
No confirmed attack impact; further source inspection is needed to resolve the remaining paths.
Mechanism
The examined credential-related code shows a user prompt for an environment token and a child process that removes the Anthropic API key. The available excerpts do not resolve the flagged network, agent configuration, and runtime behavior.
AI rationale
The scanner’s credential-redirection and reverse-shell claims are not demonstrated by the inspected excerpts, but the package’s agent integration and several flagged runtime paths remain unresolved. Manual review is appropriate because the available inspection does not support a reliable clean or malicious verdict.

Independent scan evidence
public snapshotAI called this Manual Review at 62.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The manifest exposes CLI and daemon entry points and runs a build plus a worker command only in `prepublishOnly`.
- The inspected Todoist setup prompts before using an environment token and sends the selected token to a project-listing operation.
- The CLI contains a check that treats a non-default Anthropic base URL as a proxy for traffic that may pass outside Anthropic’s API.
- A child-process helper removes the Anthropic API key from its inherited environment.
- The package captures tool output locally, but this excerpt does not establish the full hook activation or data handling.
Evidence against
- The inspected source does not establish that the CLI redirects credentials to a publisher-selected gateway or that the flagged rendering code opens a reverse shell.
- The available excerpts do not resolve all agent integration targets, CLI behavior, or required runtime paths.

Affected versions and remediation
This report applies to @tekmidian/pai@1.0.9.
See all versions of @tekmidian/pai for other recorded verdicts.
- Avoid installing @tekmidian/pai@1.0.9. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
