@octavus/agent@1.0.10

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

The package is not install-time malware, but it deliberately provides high-impact remote-agent control of local shell, files, and browser state. The explicit command and credential gate reduce the likelihood of covert abuse, while the capability remains significant enough to warn.

Static reason

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

Trigger

A user runs octoagent with configured credentials and starts a cloud-agent session.

Impact

A compromised or malicious cloud-agent session could execute commands, alter workspace files, operate browser tabs, and send recordings.

Mechanism

Remote agent dispatch into local shell, filesystem, browser, and recording tools.

AI rationale

Evidence

dist/index.jsdist/filesystem-mcp.mjsdist/browser-extension-mcp.jsdist/browser-extension/assets/index.ts-Bis5r5UE.js

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The user-invoked CLI creates a filesystem server and a shell server rooted at the selected workspace.
The filesystem server can overwrite files within its allowed directories.
The CLI sends an authenticated request to create a remote cloud-agent session.
The bundled browser extension can evaluate arbitrary script in an attached browser tab and upload recordings to a provisioned endpoint.

Evidence against

package.json has no preinstall, install, postinstall, or other lifecycle script.
The capabilities activate through the octoagent command and require configured API credentials.
No self-dependency, hidden payload loader, or automatic install-time execution was found.
