@octavus/agent@1.0.15

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 1mo ago · by lpm-firewall-ai

The package is not malicious by the install-hook standard, but it provides a dangerous remote AI-agent capability with local command execution and remote communication. Warn so consumers can assess the intended trust boundary.

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

A user runs the octoagent CLI with an authenticated agent and prompt.

Impact

A compromised or overly privileged cloud agent could read, alter, or expose data available in its selected workspace and local environment.

Mechanism

Cloud-directed local agent tooling with shell command execution.

AI rationale

Evidence

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The user-invoked CLI provisions shell, filesystem, browser, and computer-control tools for a cloud agent.
Its code MCP accepts a command and sends it to a shell execution helper, so remote agent instructions can produce local command output.
The package connects runs to the Octavus platform and stores an API key locally.

Evidence against

package.json has no preinstall, install, postinstall, or other lifecycle script.
The privileged behavior is reached only by running the octoagent command; it is not install-time or import-time.
No source evidence shows covert credential harvesting, stealth persistence, or destructive automatic behavior.
