Blackhole Hosted Mostly In US, Russia
The United States and Russia are home to the most compromised websites hosting Blackhole, according to data from U.K.-based security vendor Sophos. The security firm said attackers often register a .com domain and can turn it into an attack site within 24 hours. "Blackhole host sites move rapidly," the firm said. In addition attackers compromise the Web servers behind legitimate sites, setting them up with malicious code that generates a stealthy attack when victims visit an infected Web page.
