What system you are using NTP on?

The discoveries of openings in the NTP protocol for hacking into systems is pervasive into all operating systems - including AIX. One announcement in 2014, one in 2015- and 4 or 5 announcements (depending on how you want to count them) in the first 6 months of 2016.

In short, this year, the number and rate of discoveries have increased dramatically. So, thinking you are not affected is just putting your head in the sand - unless you are not using NTP at all.

A quick review of the announcements for AIX since 2014:
