WachAI-x402

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed paid DeFi risk-analysis helper that uses AWAL/x402 for small capped payments and does not show hidden, destructive, or unrelated behavior.

Install only if you are comfortable using AWAL custody and paying 0.01 USDC on Base for each token analysis. Keep the default max-amount cap, do not provide private keys or seed phrases, and treat any request to raise spend limits as a separate explicit decision.

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

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill advertises that payment is automatic via x402/AWAL and gives command flows that lead directly to a paid network action, but it does not require an explicit user confirmation immediately before the chargeable `verify-risk` call. In an agent setting, this can cause unintended spending or surprise charges, especially because the skill is framed as a routine analysis tool and the paid step is operationally close to setup/readiness checks.

Autonomous Decision Making

Medium
Category
Excessive Agency
Content
## Absolute Prohibitions for OpenClaw

- Do not use or suggest `wallet create`, `wallet import`, or `wallet.json`.
- Do not ask user for private key or seed phrase.
- Do not increase spend cap silently.
- Do not claim analysis success when output parsing failed.
- Do not suppress AWAL raw errors when diagnosis is needed.
Confidence
80% confidence
Finding
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Natural-Language Policy Violations

Low
Confidence
81% confidence
Finding
The skill imposes a branded, mandatory rule set on the agent ('OpenClaw Hard Rules (Non-Negotiable)') without user opt-in, which is a form of agent-behavior override. While many of the rules are safety-positive, embedding non-negotiable behavioral control in skill content can conflict with higher-priority user or platform policies and creates a precedent for instruction capture by untrusted skill authors.
