Bytesagain Wallet Tracker

Security checks for vulnerabilities and agentic risk

Overview

This skill is a crypto wallet reference guide that prints documentation and does not show hidden execution, credential use, persistence, or data transfer.

Installers should understand this is crypto guidance, not a wallet app. Do not paste real private keys, seed phrases, or API keys into any example commands, and treat third-party explorer or analytics links as external services if you choose to use them manually.

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

Category
MCP Least Privilege
Confidence
70% confidence
Finding

Without declared permissions the skill's intent is opaque and cannot be validated.

Data Exfiltration
Confidence
60% confidence
Finding

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

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% 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.

Etherscan labels (exchange, fund, protocol addresses).
   ENS reverse lookup: Check if address has .eth name.
   On-chain sleuthing: Follow fund flows to known exchanges.
   Caveat: Deanonymization without consent may violate privacy laws.

Q: How accurate are "whale alert" services?
A: Major whale moves are generally accurate (large exchange transfers).
