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.
