Security audit
BTC Radar x402
Security checks for vulnerabilities and agentic risk
Overview
This skill provides cryptocurrency data through openly disclosed USDC payments, without bundled executable code or instructions for persistent system access.
Calls spend real USDC, and advertised prices can change. Use a wallet or client with spending limits and check the amount, recipient, network, and asset before authorizing payment. Candidate signals are unverified, and a low risk score does not establish that a token is safe.
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
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- 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
