Does anyone know if the 360.cn website, or associated software is legitimate antivirus and antimalware?

 

I’ve noticed some odd traffic heading to qurl.f.360.cn on port 53.  They’re not DNS queries, but seems to be a large payload of encoded data.

That's a tough call for various reasons.  It's most likely from Chinese nationals who are using the free 360.cn antivirus software on their computers.  That software seems quite popular but is of questionable value from a protection perspective and there is speculation it provides a backdoor for Chinese government monitoring of individuals and a bridgehead into remote network for malicious activity on the part of the Chinese government or independent agents. 

Like so many things China-related, it's at least semi-legitimate but not something I'd ever trust personally.

Sorry for not seeing this earlier. I have heard of just such a scheme, namely, using TCP and UDP 53 for non-DNS traffic that they (the bad guys) are hoping will not be noticed. Typically, this is used by bots to talk to their command and control servers.
