Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed Chinese-language financial risk-reference skill with no executable code or persistence, but users should treat its banking and SBLC material as high-stakes informational guidance only.

Install only if you need Chinese-language reference material for promissory-note fraud review. Do not paste full ticket numbers, account data, SWIFT confirmations, customer names, authentication materials, or bank messages into the assistant unless they are approved and redacted. Treat the SBLC, tax, green-channel, and transaction-decision sections as non-binding background and verify any real transaction through your bank, counsel, and official regulators.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration

Natural-Language Policy Violations

Confidence
85% confidence
Finding

The skill name and description, along with the rest of the document, assume Chinese as the mandatory operating language. Under the policy for natural-language violations, forcing a specific language without user opt-in can exclude users and is not justified here as a region-specific constraint.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill claims to be a promissory-note fraud-prevention guide, but it expands into broader financing and project workflows such as gold-project funding and related instrument handling. This scope drift can cause users to rely on the skill for higher-risk financial structuring guidance outside its declared purpose, weakening guardrails and increasing the chance of unsafe or noncompliant decisions.

Context-Inappropriate Capability

Confidence
90% confidence
Finding

Including SBLC '回国机制', tax handling, and 'green channel' process guidance materially extends the skill into cross-border instrument movement and potentially sensitive regulatory workflows unrelated to basic promissory-note fraud prevention. Users could treat this as operational advice for moving financial instruments or navigating special approval paths without legal review, creating compliance, sanctions, or fraud-abuse risk.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill instructs users to perform bank/SWIFT verification and handle ticket numbers, bank confirmation messages, and related financial details, but it does not warn against sharing sensitive banking data in insecure channels or with the assistant. This can lead to unnecessary disclosure of confidential financial information, enabling privacy violations, social engineering, or downstream fraud.

Finding

The entire skill description and usage instructions are presented only in Chinese, with no indication that users may choose another language or that the skill is intentionally restricted to a Chinese-speaking or China-specific audience. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy concern.
