"The worst is yet to come" in the Edward Snowden leaks, a US official warns—and it could come all at once. American and British officials are more than a little worried about a "doomsday" cache of highly classified intelligence files the NSA leaker is believed to have stored in a data cloud, Reuters finds. The material is well-protected by encryption and multiple passwords, sources say, but experts believe intelligence experts in China or Russia, where Snowden has received temporary asylum, could crack it if they found it.
Some administration officials believe Snowden made off with enough material to keep the leaks coming for another two years. The unpublished material is believed to include plenty of potentially damaging information about the CIA—possibly including the names of agents. Adding insult to potential injury, intelligence workers in Washington, DC, dealing with the fallout from the leaks might be further angered to see ads thanking Snowden on the sides of city buses. An ad campaign hailing him as a hero for exposing "misinformation and lies told to us by politicians" began yesterday, funded by a free-speech advocacy group, reports Russia Today.
