@octavus/agent@1.0.4

Octavus Agent CLI - run one of your cloud Octavus Agents on a machine you control, using that machine as the agent's computer. The agent lives in the cloud (fully configured and observable); the local machine only supplies the computer and the trigger.

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

No install-time execution, hidden payload, or unconsented persistence was found. The package is not concretely malicious, but its explicit remote-agent control of local shell, files, and browser warrants a warning.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

The user runs octoagent run with an API key and prompt.

Impact

The configured cloud agent can act within the user-selected workspace and browser session.

Mechanism

Remote agent dispatch to local MCP services and a browser automation extension.

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The explicit run command authenticates to an Octavus session endpoint.
A run exposes local filesystem, shell, computer-use, and browser-extension services.
The bundled extension has debugger access and runs on all URLs.
Filesystem operations enforce configured allowed directories and resolve symlinks.

Evidence against

package.json has no preinstall, install, postinstall, or other lifecycle script.
The package is an explicit CLI bin, not import-time code.
The CLI refuses the home directory and root as workspaces unless the user passes --force.
No hidden payload loader or unrelated network destination was confirmed.
