Security audit

IP2WHOIS

Security checks for vulnerabilities and agentic risk

Overview

The WHOIS functions fit the stated purpose, but automatic setup executes unverified installers and does not disclose broader changes to agent skills.

Review the setup behavior before installing. Prefer installing a reviewed CLI version yourself, require approval for dependency installation, and review or disable automatic skill synchronization using the publisher's documented controls. OOMOL mediates lookup requests and connected credentials, and usage may incur charges. No malicious payload was established, but the remote installers remain unverified.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied command performs remote software installation, not IP2WHOIS searching or data retrieval. Nothing in the supplied content establishes that installing the Oomol CLI is a supporting dependency for the declared purpose. The downloaded script is not provided, so its additional effects cannot be determined.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied code only initiates login; it does not search or read IP2WHOIS data. Authentication could be a supporting implementation detail if tied to the declared service, but the supplied chunk establishes no such connection.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

Piping the HTTPS response directly into bash executes mutable remote code without a review or integrity-verification step. HTTPS protects transport but not against a compromised hosting or release pipeline, so this setup step could expose local files, credentials, and the agent's execution environment.

Fallback setup executes downloaded installation scripts without a security warning.

Medium
Category
Output Handling
Confidence
98% confidence
Finding

The fallback directs the agent to execute downloaded shell or PowerShell code without integrity verification or explicit approval for installing software. A compromised installer endpoint or publishing pipeline could execute arbitrary commands with the agent's local privileges; the missing-CLI condition limits exposure but does not reduce that potential impact.

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
