NetExec timeroast Module

Timeroast: brute computer-account passwords via the MS-SNTP authenticated NTP exchange. The DC signs replies with the machine-account RC4 key derived from its password, which can be cracked offline. No prior credentials required — the DC will sign for any computer RID you specify.
