Apollo

Security checks for vulnerabilities and agentic risk

Overview

The skill is coherent for Apollo sales workflows, but it asks users to install and allowlist an unpinned third-party credential-handling plugin that can perform Apollo reads and writes.

Review the ClawLink plugin publisher, version, and permissions before installing. This skill should only be used if you are comfortable letting ClawLink store or proxy your Apollo API access and perform confirmed Apollo CRM writes through the installed plugin.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

Session Persistence

Medium
Category
Rogue Agent
Confidence
80% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
