NTP Timeroast

Created

Description

Windows authenticates NTP requests by calculating the message digest using the NT hash followed by the first 48 bytes of the NTP message (all fields preceding the key ID). An attacker can abuse this to recover hashes that can be cracked offline for machine and trust accounts. The attacker must know the accounts RID, but because RIDs are sequential, they can easily be enumerated.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
