Reason CLI native binary for linux-x64

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The manifest has no install lifecycle hook, and the inspected credential handover is presented as an optional CLI connection feature. The 102 MB native executable has only bounded embedded-source analysis, leaving material behavior unresolved; manual review is appropriate.

Static reason

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

Trigger

Running the packaged CLI may activate code in the native executable; the inspected token handover is activated by a persistent connection with local login handover enabled.

Impact

The inspected login handover is described as allowing local logins to serve Sessions, but the native executable's remaining behavior cannot be resolved from the available analysis.

Mechanism

The inspected bundle reads local provider login tokens and supplies them to a subscription client. The available native analysis does not establish whether all embedded code is reachable or whether other behavior exists.

Decision evidence

public snapshot

AI called this Manual Review at 91.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json identifies this as the Linux x64 Reason CLI binary package.
The CLI reads locally stored provider login tokens and passes them to a local subscription client when local login handover is enabled.
Persistent connection settings default local login handover to enabled, and the CLI describes those logins as serving its Sessions; users can turn the feature off.
The bundle lists Reason Machines production and staging API endpoints for its service configuration.
The inspected native analysis covers bounded embedded source windows and says they do not establish loader reachability or rule out other native behavior.

Evidence against

The manifest contains no lifecycle scripts, and the inspected token handover is presented as a CLI feature with a disable option; these facts do not resolve all behavior in the native executable.
