Whoami Tool Check

• Outcome: Review
• Latest audit: Sep 16, 2026 · 8:14 AM UTC
• Version: 1.0.0

Overview

This skill looks non-destructive, but it advertises security audit features that the included tool does not actually implement.

Do not rely on this skill for access reviews or security audits unless the advertised checks are implemented and tested. As packaged, it is essentially a simple username printer with misleading audit documentation.

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration

Findings (8)

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence

Finding

The skill advertises identity, sudo, role, and capability auditing features that static analysis says are not actually implemented. This can mislead operators into trusting incomplete security checks, creating a false sense of assurance and potentially causing missed detections or unsafe decisions based on nonexistent validation.

Undeclared Tool Scope

Medium

• Category: MCP Least Privilege
• Confidence: 70% confidence

Finding

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

Sudo/Root Execution

Medium

• Category: Privilege Escalation
• Confidence: 70% confidence

Finding

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
