When you use Hashcat

  • Pen-test: you extracted NTLM hashes from an AD dump (DCSync, ntds.dit). Crack to recover passwords.
  • Pen-test: you recovered /etc/shadow. Crack SHA-512 hashes.
  • Pen-test: Kerberoasting returned service ticket hashes (mode 13100). Crack to get service passwords.
  • Audit: check your own password policy by attempting to crack your own hash dumps. Gauge hygiene.
