Zeus Dealt Blow After Two ISPs Knocked Out

Two ISPs, named Troyak and Group 3, linked to the notorious Zeus botnet, were taken down, according to Computerworld. The ISPs were responsible for a third of the command-and-control servers that run the network of hacked machines.

However, just hours after Internet service providers knocked out network connectivity to Troyak, the ISP was back online. As Computerworld notes:

That means the 68 Zeus botnet command-and-control servers associated with Troyak can reconnect to hacked systems and issue new instructions.
