Fathom

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Fathom integration that uses Maton OAuth to access meeting data and includes strong approval and data-forwarding safeguards.

Before installing, understand that this skill can access sensitive Fathom meeting content and can create persistent webhooks or automations if you approve them. Use read-only actions where possible, confirm every destination URL and webhook scope carefully, and revoke/delete connections, functions, triggers, or webhooks when no longer needed.

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
