Room: Enumeration & Brute Force by the amazing TryHackMe!

Hi All!

Let me give you a quick rundown of this awesome TryHackMe room. The best part? It’s FREE to access! But, if you’re serious about diving deeper into cybersecurity, I highly recommend becoming a premium user. Trust me, it’s worth every penny.

Now, let’s get into the nitty-gritty. The Enumeration & Brute Force room is packed with knowledge, challenges, and practical insights. Here’s what you need to know:

Task 1 – Introduction

Get ready to explore the fundamentals of enumeration and brute force attacks. These techniques are critical for penetration testing and understanding system vulnerabilities.

Task 2 – Authentication Enumeration

Q: Which feature, if poorly implemented, can assist attackers in gathering valid usernames through its response differences?

A: Password reset

Q: What type of error messages can unintentionally provide attackers with confirmation of valid usernames?

A: Verbose errors

Additional sources:

• Rapid7: About User Enumeration

• OWASP: Testing for Account Enumeration

Task 3 – Enumerating Users via Verbose Errors

Q: What is the valid email address from the list?

A: canderson@gmail.com

Task 4 – Exploiting Vulnerable Password Reset Logic

Weak password reset flows are a goldmine for attackers. Always test for predictability in reset links, token expiration, and more.
