AssetFare Route

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed AssetFare routing guide for quotes and user-approved unsigned bridge actions, with clear safeguards against signing, submission, private-key handling, or automatic execution.

Before installing, understand that this skill can guide an agent through financial bridge-route quotes and unsigned action preparation. Use it only when you are comfortable sending route details and public wallet information to AssetFare, and independently verify every quote, fee, recipient, chain, amount, session token handling, and unsigned action before signing in your own wallet.

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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

the fresh fee-inclusive output before any separate execution selection.
4. Require caller approval before `assetfare_start_wallet_auth`, session creation, or action preparation.
5. The wallet owner signs only the exact non-transactional login message.
6. Keep the returned access token out of source, logs, issues, and transcripts.
7. Verify every `agent_must_verify` item before the caller signs an unsigned action.

After any delay or error, read the workflow state and current asset location. Never guess, silently rebuild, or resend a stale action.

External Transmission

Medium
Category
Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
