Day 27 · Week 4

Password cracking and Checkmate

Complete Password Cracking, then apply hash identification and cracking decisions independently in Checkmate.

TryHackMe rooms

Corresponding practice

  • Identify each room-provided hash from structure and context before selecting a tool or mode.
  • Record why Hashcat or John the Ripper is appropriate for each case.
  • Start with a dictionary attack, then document one justified rule or mask change if needed.
  • Attempt Checkmate independently and keep a hypothesis/evidence log.

Evidence to capture

  • Hash identification and tool-selection table
  • Sanitised commands using only room-provided hashes
  • Checkmate decision log and defensive note on salts and password policy

What I learned

Explain the difference between online authentication attacks and offline hash cracking.

Problems and dead ends

Record incorrect hash modes, formats, or wordlist assumptions.

What I will revisit

Repeat one crack from raw evidence without using the room hint.
