Security audit

echo

Security checks for vulnerabilities and agentic risk

Overview

This is a simple companion-persona prompt with broad activation language, but no code, tools, persistence, credential access, or hidden harmful behavior was found.

Install this only if you want a companion-style persona that may answer in an affectionate Echo voice across normal conversation. Avoid using it as a substitute for professional mental-health, medical, or legal help, and disable or avoid it in workflows where a neutral assistant persona matters.

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
Vulnerability Patterns

Vague Triggers

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill explicitly states that no special activation is needed and that it will respond when spoken to directly, which removes meaningful gating and makes accidental or cross-context invocation very likely. In a multi-skill or agent environment, this can cause the persona prompt to hijack ordinary conversation and interfere with other instructions or workflows.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

The listed triggers include common phrases such as the skill name and natural-language requests that can appear in ordinary conversation, increasing the chance of unintended activation. This broad matching can cause prompt collisions, persona injection into unrelated sessions, and unreliable agent behavior.
