Epoch Time Converter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small local timestamp converter with no evidence of data theft, persistence, or unsafe system changes.

This appears safe to install for timestamp conversion. Be aware that short timezone phrases may invoke it more often than intended, so check that the requested conversion and timezone match what you meant.

A.I.G

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

Finding

The manifest description says the skill triggers on phrases like "to UTC" and "to Asia/Shanghai", which are common fragments that could appear in many conversations unrelated to epoch conversion. Because the trigger scope is not constrained by requiring an epoch/date conversion context or explicit exclusion examples, this risks unintended invocation.
