The Treasury Department has taken offline four public websites for the Bureau of Engraving and Printing after the discovery earlier this week of malicious code on a parent site, Federal Computer Week reports. The bureau began using a third-party cloud service provider to host the sites last year, Treasury said in a statement about the incident. That company had an intrusion and as a result of that intrusion, a number of Treasury Web sites were affected, the statement said. The Treasury Government Security Operations Center was alerted to the problem and notified the bureau, which responded by taking the sites offline. We told you yesterday that the hacks were first reported by Roger Thompson, chief research officer for AVG Technologies, who discovered malicious code injected into the affected page on Monday. He said the code appears to link with two attack servers in Ukraine.
