Futu Flash

Security checks for vulnerabilities and agentic risk

Overview

This skill fetches recent Futu flash news from a fixed public endpoint and does not show hidden persistence, credential access, or destructive behavior.

Install this only if you are comfortable with the skill making user-requested GET requests to news.futunn.com for current news. Expect Chinese-market defaults such as Beijing time and zh-CN language preference; no evidence was found of credential use, persistence, local data access, or destructive actions.

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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
94% confidence
Finding

The skill instructs the agent to perform live network access to an external endpoint but does not declare any explicit tool scope or allowed-tools boundary. This weakens policy enforcement and reviewability, because a host environment may permit broader network/tool usage than the skill actually needs, increasing the chance of unintended external access or abuse if the skill is modified or composed with other behaviors.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The instruction requires converting times to Beijing time (UTC+8) for output, imposing a locale-specific presentation by default. The file does not offer a user choice or document this as an explicitly region-scoped compliance requirement.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
94% confidence
Finding

The request headers hard-code Accept-Language: zh-CN,zh;q=0.9, which imposes a specific language/locale preference in the skill's behavior. The file does not offer user opt-in or configuration for locale, and no region-specific justification is documented in the script.
