AI Security Review

scanned 20d ago · by lpm-firewall-ai

Inspectable source is a first-party npm wrapper that fetches the matching GitHub release, verifies SHA256SUMS, and bootstraps a managed runtime inside the package tree. No credential theft, foreign agent-config writes, or unrelated network sink is present in the published JavaScript.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm install runs postinstall; user-invoked ccb, ask, autonew, or ctx-transfer also call the same installer before spawning the extracted binary.

Impact

No confirmed malicious impact in the published package source.

Mechanism

Package-aligned GitHub release download and local runtime bootstrap

AI rationale

Readable postinstall code downloads the same-version GitHub release for this CLI, checks SHA256SUMS, and bootstraps under .ccb-release with role install disabled. Scanner malware fingerprints are a noisy match to that downloader shape, not a concrete attack in this source.

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json has a postinstall that runs bin/ccb-npm-install.js, with no runtime dependencies and no self-dependency on another @seemseam/ccb release.
The installer downloads the matching-version archive and SHA256SUMS from the GitHub SeemSeam/claude_codex_bridge release (or operator CCB_NPM_RELEASE_BASE_URL), checks the digest, and extracts under the package .ccb-release directory.
