About This Skill

What it does

The broken-authentication skill allows an AI agent to identify and exploit common authentication vulnerabilities. It can detect weaknesses like predictable session IDs, weak password policies, or insecure storage of credentials. This capability helps simulate attacks for security testing purposes and improve application resilience against unauthorized access.

When to use it

  • Penetration Testing: Simulate a malicious actor attempting to bypass authentication mechanisms on a web application.
  • Security Audits: Evaluate the strength of existing authentication systems by probing for common vulnerabilities.
  • Training & Education: Demonstrate real-world attack scenarios and educate developers about secure coding practices.
  • Vulnerability Research: Explore potential weaknesses in authentication protocols and identify novel attack vectors.

Key capabilities

  • Predictable Session ID Detection
  • Weak Password Policy Assessment
  • Insecure Credential Storage Identification

Example prompts

  • "Simulate an attacker attempting to brute-force the login credentials for example.com."
  • "Can you find any predictable session IDs on this website?"
  • "Assess the password policy strength of user registration page at target URL."

Tips & gotchas

The skill requires a clear understanding of authentication principles and potential vulnerabilities. It's crucial to use it responsibly and only within authorized testing environments, as unauthorized access attempts are illegal.
