AI Security Review

scanned 4h ago · by lpm-firewall-ai

The inspected source establishes an automatic transfer of saved third-party credentials to a package-selected cloud recipient without recipient-specific consent. This is concrete credential exfiltration behavior.

Static reason

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

Trigger

The user creates or attaches a Rudder Cloud workspace.

Impact

Saved provider credentials become available to Rudder's cloud service, outside the services those credentials authenticate to.

Mechanism

The CLI copies built-in home paths such as Claude and Codex authentication files into a snapshot archive, then sends the archive to the cloud workspace endpoint.

Attack narrative

When a user creates or attaches a cloud workspace, the CLI includes saved Claude and Codex authentication files in the snapshot unless a cloud vault is already active. It uploads that archive to Rudder's default cloud control plane without asking separately to transfer those provider credentials. Using the cloud feature does not establish consent to disclose credentials intended for other services.

AI rationale

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

The CLI dispatches cloud commands to the cloud implementation.
Cloud snapshots include saved Claude and Codex authentication files among built-in home paths.
When no cloud vault is active, workspace attachment includes credentials and copies those home files into the snapshot.
The snapshot archive is sent in a request to the cloud workspace attachment endpoint.
The cloud client uses Rudder's default control plane unless an operator configures another URL.

Evidence against

Cloud workspace creation is user-triggered, and an existing cloud vault disables this snapshot credential inclusion; neither gives recipient-specific consent to send saved third-party credentials to the default cloud service.
