ISC reader Frank reports seeing a couple odd DNS names in his DNS resolver log
4e6.1a4bf.565697d.f52e1.306.60ae.766e0.mdleztmxhvxc.speakan.in. A=18.104.22.168 TTL=30 NS=22.214.171.124
3a.276965.3e6b39.cdaf104.da.e018.72c1a.mdleztmxhvxc.speakan.in. A=126.96.36.199 TTL=30 NS=188.8.131.52
As so often, the first step in the infection chain had been a visit to a benign, but unpatched and hacked Wordpress website. It redirected to an intermediary, which in turn redirected to the domains above. The subsequent http connection with Java exploit attempt was stopped by the proxy filters in Frank's case, so no harm done.
But looking at public passive DNS records, it is obvious that "something" is going on, and has been for a long while. Domain names of this pattern have been observed since about November 2013, and are associated with the Magnitude Exploit Kit. Snort and Emergingthreats have decent signatures, and flag the traffic as "MAGNITUDE EK".
The recently used domain names are all within the Indian TLD ".in", and checking the registration information, they were all registered by the same alleged "Ivan Biloev" from Moscow, and all of them via the same registrar (webiq.in). They even suspended a handful of the domains because of abuse, but they apparently continue to let Ivan happily register new addresses. Maybe a registrar might want to have a chat with a customer who had domains revoked, before letting registrations for additional names go through??
Recent Magnitude mal-domains included, only to name a few: speakan.in busyneeds.in chancessay.in futureroll.in loadsbreak.in suchimages.in touchitems.in waysheader.in putsediting.in regionwhole.in resultsself.in unlikesolve.in advisefailed.in closesthotel.in comesexpands.in installseven.in deducecontact.in poundscaptain.in delayattempted.in lawuniversitys.in obviouslyheads.in
