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

Clean

Independent AI assessment: clean. LPM AI assessed this version as clean; the assessments disagree.

The critical scanner hints resolve to ordinary content processing, while agent hooks store data locally and settings changes require confirmation. The package manifest has no consumer install hook, and the inspected sources show no concrete attack behavior.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Running the package's setup command and accepting its settings prompt enables the configured hooks.

Impact

The reviewed behavior can store agent content locally and add declared settings after confirmation; no attack impact was established.

Mechanism

Hooks save session and tool-output data under PAI paths; the reviewed sources did not establish remote transfer, unconsented agent configuration changes, or remote code execution.

AI rationale

Evidence

package.jsondist/cli/index.mjsdist/hooks/capture-all-events.mjsdist/hooks/capture-session-summary.mjsdist/hooks/capture-tool-output.mjsdist/hooks/handoff-link.mjsdist/hooks/initialize-session.mjsdist/hooks/route-agents-to-worker.mjsdist/hooks/whisper-reinject.mjsdist/hooks/whisper-rules.mjs

Independent scan evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json has no consumer install hook; its only lifecycle entry is prepublishOnly.
The Claude settings patch is an explicit setup step that asks before proceeding.
The inspected hooks write session, tool-output, link, ledger, debounce, and marker data to local PAI paths.
The flagged runtime excerpts show content formatting and ordinary process, configuration, and session support; they do not establish a reverse shell or downloaded code execution.
The required dependency sources show model, MCP, and database libraries; better-sqlite3 uses native prebuild or node-gyp setup.

Evidence against

Hooks capture agent session and tool-output content locally, and the prompted setup can add permissions to Claude settings.
