The hackers allegedly behind the hack of Sony Pictures are congratulating the FBI on its work and offering the bureau a "Christmas gift." "The result of investigation by FBI is so excellent that you might have seen what we were doing with your own eyes," a broken-English message attributed to the "Guardians of Peace" hackers says at pastebin.com. "We congratulate you success. FBI is the BEST in the world." The message links to a YouTube video titled "you are an idiot," CNN reports; the clip features upbeat electronic music and smiley faces.
North Korea earlier demanded a joint investigation with the US into the hack. "If the North Korean government wants to help, they can admit their culpability and compensate Sony for the damages this attack caused," a US national security rep says, as the BBC reports. But the US does appear to be seeking a partner against hacking: Officials have been communicating with China about barring North Korean cyberattacks, the New York Times reports. "What we are looking for is a blocking action, something that would cripple their efforts to carry out attacks," an insider says. Meanwhile, Sony says it hasn't entirely given up on The Interview, the Independent reports. The studio is "surveying alternatives to enable us to release the movie on a different platform," it says in a statement. (Read more Sony stories.)
