Phantombuster

Security checks across malware telemetry and agentic risk

Overview

This Phantombuster skill appears legitimate, but it lets an agent change and run automations through an authenticated account without clear approval safeguards.

Install only if you trust Membrane and intend to let an agent operate your Phantombuster account. Require explicit approval before script changes, agent launches or aborts, and raw proxy API calls; consider pinning the CLI version and revoke the Membrane connection when finished.

Finding
The skill documents both state-changing actions and raw proxied API requests without any guardrails around confirmation, scope validation, or destructive-operation warnings. In an agent setting, this can enable unintended launches, aborts, script changes, or direct API mutations if the model acts on ambiguous or adversarial prompts.
