Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple delivery acknowledgement helper with no code, persistence, credential access, or hidden behavior.

This appears safe to install for routine delivery acknowledgement tasks. Users should still invoke it only when they intend to set acknowledgement guidance or create an acknowledgement receipt, since the top-level trigger could be worded more narrowly.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Vague Triggers

Medium
Confidence
94% confidence
Finding
The instruction 'Use this skill for routine delivery acknowledgement work' is a broad natural-language trigger that does not clearly delimit when the skill should or should not activate. The file does not provide exclusion conditions or negative examples, which increases the risk of unintended invocation for loosely related delivery tasks.
