Blockchain Developer

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward API description for generating blockchain career roadmaps, with expected user-provided profile data sent to a disclosed external endpoint.

Before installing, treat any submitted assessment as data sent to ToolWeb/api.mkkpro.com infrastructure. Avoid sending unnecessary personal identifiers or sensitive employment details unless you are comfortable with that service handling them.

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
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill includes example payloads with session identifiers, optional user identifiers, timestamps, and detailed assessment/profile data, but it does not clearly disclose that this information is sent to a third-party external API. In a career-guidance context, users may reasonably provide personally identifying or sensitive professional profile information, creating a privacy and consent risk if transmission happens without explicit notice and data-minimization guidance.

External Transmission

Medium
Category
Data Exfiltration
Confidence
84% confidence
Finding

The skill references an external API endpoint, which confirms data leaves the local environment and is sent to a third-party service. By itself external transmission is expected for an API skill, but here it becomes security-relevant because the transmitted content includes session/user identifiers and assessment data, and the skill does not provide sufficient trust, privacy, or handling assurances for that remote service.
