⚠ Under review

Reason CLI native binary for linux-arm64

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The JavaScript skill setup is an explicit user command, and the manifest shows no lifecycle hook. The 90 MB native executable was only partially analyzed, so its behavior cannot be resolved from the inspected evidence.

Static reason

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

Trigger

Unknown from the available static analysis.

Impact

No attack impact can be confirmed or excluded for the unresolved executable.

Mechanism

The available analysis contains bounded embedded source samples and does not establish the executable's full behavior.

AI rationale

Evidence

bin/reason.lpm-inspection-A3lF0E/0-61b49a1f49c1.txt

Decision evidence

public snapshot

AI called this Manual Review at 94.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as a Linux ARM64 native CLI package.
The source analysis identifies bin/reason as a 90 MB ELF executable, but covers only bounded embedded source windows and says those windows cannot establish its full behavior.
The inspected trace code installs a project skill through an explicit install-skill command.

Evidence against

The inspected manifest contains no lifecycle hook.
The observed skill installation is exposed as a user-invoked trace subcommand.
