In our IPS log I see the following entry *TCP C2S Ambiguity: Data in
SYN Packet* daily directed towards our DNS server. These packets are
coming from four or so different addresses in China.  I did a brief
Google search with results being a few or more years old. A couple of
the posts reported the same *Data in SYN Packet* with the
originating addresses also from China.

Can anybody shed light on this?


If you still see it coming and can grab some full packet capture samples
of them and don't mind sending them to me I'd like to take a look.
