Security checks for vulnerabilities and agentic risk

Overview

The skill is a banking helper that avoids transfers and credential automation, but it directs agents to process personal online-banking bill data while framing it as non-sensitive.

Review carefully before installing. Use this only for public PSBC product or announcement summaries, or for authenticated banking pages when you deliberately provide the page and want a minimal aggregated summary. Do not let it process full transaction details, account identifiers, session-bearing URLs, credentials, or anything you would not want retained in chat history or logs.

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
