Security checks for vulnerabilities and agentic risk

Overview

This skill is a public-web company news briefing helper with no executable code, persistence, credential handling, or hidden behavior found.

Install only if you want a Chinese-first briefing workflow that uses public web search/reading across DXC, company, customer, industry, tender, and competitor sources. Review generated business opportunities before acting, since the reference file notes some content may be AI-generated.

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

Findings (2)

Natural-Language Policy Violations

Medium
Confidence
92% confidence
Finding
The entire document is presented in Chinese, including headings, guidance, and usage instructions, with no indication that language selection is optional or that the content is intended only for a Chinese-speaking or region-specific audience. Under the policy, forcing a specific language without user opt-in is a natural-language locale violation.

Natural-Language Policy Violations

Low
Confidence
90% confidence
Finding
The natural-language instruction "用户触发场景（中文为主，英文兼容）" indicates a default language policy that prioritizes Chinese rather than offering an explicit user choice. Under the policy-violation rule, forcing or preferring a specific language without opt-in can be considered a locale/language constraint.
