Security audit

WhoisFreaks

Security checks for vulnerabilities and agentic risk

Overview

The skill mostly matches its WhoisFreaks lookup purpose, but its setup instructions can lead an agent to run an unverified remote installer script.

Review this before installing if you are not comfortable with an agent running a remote installer. Prefer installing the oo CLI yourself from a trusted, verified source, then use the skill only for the listed WhoisFreaks actions and confirm any future write or destructive action payloads.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

External Script Fetching

Confidence

Finding

The skill instructs users to install software via curl ... | bash, which executes a remote script without verification, pinning, or integrity checks. If the distribution endpoint, DNS, TLS trust chain, or hosting account is compromised, arbitrary code could run on the user's machine with the user's privileges.
