Agent Phone SMS

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Anima phone/SMS setup guide with expected external API use and no hidden code or persistence.

Install only if you intend to use Anima for agent phone/SMS/voice. Be aware it can create an external identity, handle API keys, and lead to a paid Starter plan before phone provisioning; keep keys in approved secret storage and review any SMS or voice use for consent, privacy, and compliance.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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
