This story is very dubious. Timing very suspect. No official willing to say any of this on record yet they do a simultaneous briefing to the BBC and Sunday Time

This story is very dubious. Timing very suspect. No official willing to say any of this on record yet they do a simultaneous briefing to the BBC and Sunday Times? China and Russia both decrypting the cache? Notice how none of the actual quotes say that China/Russia decrypted anything or have access to info not in the public domain. “It is the case that Russians and Chinese have information. It has meant agents have had to be moved and that knowledge of how we operate has stopped us getting vital information. There is no evidence of anyone being harmed.” The Sunday Times article can't even get some basic facts right: "David Miranda, the boyfriend of the Guardian journalist Glenn Greenwald, was seized at Heathrow in 2013 in possession of 58,000 “highly classified” intelligence documents after visiting Snowden in Moscow." Not true. He was visiting Poitras in Berlin. I'm gonna need more evidence than 'anonymous government sources' for this.
