Ru Pack

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Russian-language informational skill pack with no executable code, persistence, external access, or hidden install behavior, though users should treat its legal, medical, and tax help as informational only.

Install only if you want a Russian-language helper for understanding documents and drafting plain-language responses. For medical results, contracts, complaints, and taxes, use it as a first-pass explanation aid and verify important decisions with a qualified doctor, lawyer, accountant, or official source.

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 (3)

Tp2

High

Category: MCP Tool Poisoning
Confidence: 90% confidence
Finding: Confusable Unicode characters (e.g., Cyrillic or Greek lookalikes of Latin letters) can make a malicious tool name appear identical to a trusted one.

Natural-Language Policy Violations

Medium

Confidence: 92% confidence
Finding: The description explicitly targets 'русскоязычных пользователей', and the skill name and examples are entirely Russian-language. Because the file presents a language-specific constraint without an explicit user choice or documented justification, it can violate language/locale policy expectations.

Vague Triggers

Medium

Confidence: 95% confidence
Finding: The package says it will 'itself determine the needed skill' from whatever the user writes, but it does not define clear routing boundaries, exclusions, or confirmation behavior. That can cause misclassification of user intent and accidental invocation of sensitive domains like medical, legal, or tax guidance from ambiguous input, increasing the chance of unsafe or inappropriate responses.
