ISO17025审核技能

Security checks for vulnerabilities and agentic risk

Overview

This is a markdown-only ISO17025/CNAS audit assistant with disclosed, purpose-aligned behavior, though users should limit sensitive lab or customer data they provide.

Install only if you need Chinese CNAS/ISO17025 audit assistance. Provide excerpts or redacted copies where possible, and remove customer names, sample identifiers, signatures, contact details, equipment serial numbers, and other confidential records unless sharing them is authorized.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Confidence
93% confidence
Finding

触发条件仅依赖“内部审核、文件审核、审核清单、不符合项、审核报告”等宽泛关键词,可能在不适当上下文中自动激活技能,并引导用户上传体系文件、审核发现或内部记录。该技能处理的往往是实验室内部管理文档,误触发会扩大敏感信息暴露面,并增加错误适用的风险。

Confidence
91% confidence
Finding

技能明确要求用户提供实验室体系文件和审核发现,但未提示这些材料可能包含受控文件、客户信息、检测数据、设备资产信息、签名记录或内部缺陷信息。对于实验室审核场景,这类文档通常具有较高敏感性,缺少最基本的数据最小化、脱敏和授权提示,容易导致不必要的敏感信息泄露。

Whitespace Padding

Medium
Category
Prompt Injection
Confidence
80% confidence
Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
81% confidence
Finding

This markdown file is almost entirely presented in Chinese, with no statement that the language choice is optional or limited to a China-specific audience. Under the policy rule for natural-language content, forcing a specific language without user opt-in can be a locale-policy concern unless the constraint is explicitly documented and justified.
