Intersesting traffic, really. Looks like they configured their Changeip.com domain name ftp.jlesher.xxuz.com to point to 21.216.185.67.
216.185.67.21, which you can see also being used by this malware is very similar.
Unconfirmed theory here is that malware receives DNS replies 21.216.185.67 and 110.4.3.2 and transforms them into 216.185.67.21:443 by transposing 21 for the IP address and by using the following forumula to turn 110.4.3.2 into the port number a.b.c.d - 110.4.3.2, (a*b)+c =443
(Many thanks To Scott D. for clueing me in about such possibility and Jack M for the relevant discussions and ideas).
I think the the benefits of such arrangement would be diversion for the admins (blocking 110.4.3.2 and 21.216.185.67 achieves nothing) and ability to change IP ports by just changing IP address on their domain in Changeip.com.
Your thoughts or othes theories are welcome. If we confirm anything, we will post the code or additional info.
