⚠ Under review

Reason CLI native binary for linux-x64

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The inspected credential handoff is presented as a Reason CLI feature, and no independent attack was verified. The package includes a large native executable whose bounded analysis cannot establish complete behavior, so manual review is warranted.

Static reason

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

Trigger

Unknown for the native executable; the inspected local-login handoff activates when the CLI connects a computer with that feature enabled.

Impact

No attack impact was established; additional native behavior cannot be ruled out from the available analysis.

Mechanism

The inspected JavaScript gathers local login data and calls the Reason client's local-subscription operation. The available native analysis cannot confirm how all embedded code is loaded or behaves.

AI rationale

Evidence

bin/ara.lpm-inspection-QB3rXd/0-2c782141f659.txt

Decision evidence

public snapshot

AI called this Manual Review at 82.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as the Linux x64 Reason CLI package.
Offline analysis identifies bin/ara as a 102 MB ELF executable and says bounded embedded source cannot establish its reachability or exclude other native behavior.
The inspected JavaScript defaults local-login support on unless configuration or an API key overrides it, then starts the handoff when enabled.
The handoff calls the client’s local-subscription operation; the CLI help discloses that current local login access tokens are used, with the feature on by default.

Evidence against

The inspected credential handoff is described as a Reason CLI feature and uses the Reason client operation; no independent malicious behavior was established.
