When it comes to hacking, the things that you don't expect end up giving up information.

NTP is a protocol that we use for synchronizing our clocks between all the systems in a LAN network. This has been around for decades, having been developed in 1981 by David Mills. In a domain, one of the most important settings will be time, and all the computers in the domain need to be within a certain timeframe. For example, in the Microsoft world, the computers or the desktops themselves can't be more than 5 minutes out of sync. Now, technically, domain controllers use NTP with what...
