"The FBI is warning U.S. companies to be on the lookout for a malicious computer program that has been linked to the hack of the Office of Personnel Management," writes Shane Harris .
"The warning, known as an FBI Liaison Alert System, or FLASH, contains technical details of the malware and describes how it works. While the message doesn’t mention the OPM hack, the Sakula malware is used by Chinese hacker groups, according to security experts. And the FBI message is identical to one the bureau sent companies on June 5, a day after the Obama administration said the OPM had been hacked."
"FBI said it was sending the alert again because of concerns that not all companies had received it the first time. Apparently, some of their email filters weren’t configured to let the FBI message through."
