Reason CLI native binary for linux-arm64-musl

AI Security Review

scanned 5h ago · by lpm-firewall-ai

The manifest excerpt shows no lifecycle script, and the inspected JavaScript did not establish a concrete attack. The package’s main ELF executable remains materially unresolved because its bounded analysis cannot establish reachable behavior or rule out other native behavior, so manual review is appropriate.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Execution of bin/reason.

Impact

Unknown until the executable’s behavior is resolved.

Mechanism

The available analysis covers bounded embedded source windows and does not establish which code is reached or whether other native behavior exists.

AI rationale

Evidence

bin/reason.lpm-inspection-DG4D22/0-692cf6d90029.txt

Decision evidence

public snapshot

AI called this Manual Review at 84.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as a Linux ARM64 musl native CLI package and declares no lifecycle script in the inspected manifest excerpt.
The 83 MB ELF executable has only bounded embedded source analysis; the analysis says it cannot establish loader reachability or rule out other native behavior.

Evidence against

The inspected manifest excerpt shows no install-time lifecycle hook.
