DMM Ranking Lite

Security checks for vulnerabilities and agentic risk

Overview

This skill only guides an agent to collect public DMM/FANZA ranking entries and format them in Chinese with Japanese titles.

Install only if you are comfortable with an agent opening DMM/FANZA adult-content ranking pages and extracting public titles and cover URLs. The skill is oriented toward Chinese output by default, so ask for a different language if needed.

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

Natural-Language Policy Violations

Medium
Confidence
94% confidence
Finding
The skill text states '默认中文说明' and fixes `output_lang` to `zh-CN`, which imposes a specific language/locale preference in the instructions. The policy allows locale constraints only when the user is given a choice or the restriction is clearly justified, neither of which is present here.
