Microsoft takedown of Zeus botnets missed a few C&Cs
Posted on 04.04.2012
When Microsoft, the financial services industry and Kyrus Tech teamed up to sinkhole a number of worldwide botnets using the Zeus family of malware, they managed to get the court's permission to seize the C&C servers in two hosting locations in the US.

But, according to FireEye's Atif Mushtaq, they haven't succeeded in taking down all of them, and of the remaining nine of one particular botnet, three (isdfsrttyqza.c0m.li, mylemain.com and stockli.us) are still active and sending out commands to zombie computers.

Mushtaq says that it is no wonder, as this particular Zeus variant is known for rapidly changing its C&C servers.

Two of the servers still out of reach of Microsoft are no longer resolving to an IP address, and four have been abandoned.

"I am not sure why the MS Digital Crime Unit has not been able to sinkhole all the C&C domains," he says. "Their main concern should be the three active domains. Without these domains completely destroyed, this botnet can not be officially declared as dead."

Cloned, booby-trapped Dark Web sites steal bitcoins, login credentials

Apart from being a way for dissidents and journalists to do their business without being spotted and identified by "the powers that be", the Dark Web is also a place where criminals sell and buy illegal wares and services and, apparently, where they also get robbed by scammers.
