Security audit

greyghound

Security checks for vulnerabilities and agentic risk

Overview

This skill fetches public greyhound racing information and optionally analyzes it locally, with no hidden persistence, credential use, or unrelated data sharing found.

Before installing, understand that the skill may browse public racing websites or APIs and may use local Python execution for scoring if available. The behavior is disclosed and aligned with the skill's purpose, but predictions should not be treated as reliable gambling advice.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

2. **Fetch data**: 
   - Use web_search or browse_page to get upcoming race cards from sites like gbgb.org.uk, sportinglife.com/greyhounds, or timeform.com/greyhounds.
   - Example: Browse "https://www.gbgb.org.uk/racing/todays-trials-meetings/" for today's races, or API like "https://api.gbgb.org.uk/api/results?page=1&date={today}&track={track}" for form.
   - Gather: Dog names, traps, recent form (e.g., 12131 = positions in last 5 races), best times, odds, trainer form.
