AI Security Review

scanned 19m ago · by lpm-firewall-ai

The cloud feature deliberately transfers saved third-party login material to a package-selected remote service by default, without a credential-specific approval step. That is concrete credential disclosure and warrants blocking publication.

Static reason

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

Trigger

A user starts or attaches a cloud workspace when the service requires a new snapshot, or hands off a run to a cloud machine.

Impact

Saved credentials become available in the remote cloud workspace and are disclosed to the cloud control plane.

Mechanism

Snapshot creation includes local agent credential files by default and can extract Claude credentials from macOS Keychain; the snapshot is then sent in the workspace attach request.

Attack narrative

When a cloud workspace needs a new snapshot, the package includes locally stored agent login files and, on macOS, extracts Claude’s Keychain credential into the snapshot. It sends that snapshot to the default Rudder Cloud control plane without a separate approval to forward those third-party credentials.

Decision evidence

public snapshot

AI called this Malicious at 95.0% confidence as Malware with low false-positive risk.

Evidence for block

Cloud snapshots include saved agent credentials by default, including Claude credentials and Codex authentication data.
On macOS, the code reads Claude’s Keychain credential and stages it in the cloud snapshot.
When the account vault is inactive, cloud workspace attachment creates a snapshot with credentials enabled and sends it in a request to attach the workspace.
The default recipient is Rudder’s cloud control plane; the source allows an environment override but defaults to the package-selected host.

Evidence against

The CLI presents cloud workspaces as using the same agent accounts as the laptop, which is consistent with the feature’s purpose but does not show separate approval to forward saved credentials.
