> We learned that these packets appeared to be legitimate, well-formed Simple Network Time Protocol (SNTP) version 1 queries, albeit at an inexplicably high rate from each client host. For instance, during one trace, many clients produced about one query per second. This would be highly unusual for a properly constructed SNTP client, since an application which uses SNTP is merely interested in setting its own clock relatively accurately so that its host has some reasonable notion of the current time. One query per second is ridiculous, and is far from best practice for NTP client behavior.
I love articles like that.
