Security audit

seo-geo

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only SEO/GEO auditing skill whose website checks and optional SEO-tool integrations fit its stated purpose.

Installers should be comfortable with the skill fetching and analyzing the websites or search queries they ask it to audit, and with optional DataForSEO-style tools receiving those domains or queries if configured. No evidence suggests hidden execution, credential use, persistence, or destructive behavior.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
