Cryptography

Security checks for vulnerabilities and agentic risk

Overview

This is a static Chinese-language cryptography reference with no executable install steps, hidden behavior, persistence, or data access.

Installers should treat this as a cryptography study/reference skill. The main practical limitation is that the content is primarily in Chinese, so users who prefer another language may need to ask the agent to translate or respond in their preferred language.

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

  • 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

Natural-Language Policy Violations

Medium
Confidence
88% confidence
Finding
The skill heading and content are written entirely in Chinese, with no indication that users may choose another language or locale. Under the stated policy, forcing a specific language without opt-in can be a natural-language policy violation unless the locale constraint is clearly documented and justified.
