Surveillance Backdoor Enabled Chinese Gmail Attack?

Major Blud writes "CNN is running an opinion piece on their front page from security technologist Bruce Schneier, in which he suggests that 'In order to comply with government search warrants on user data, Google created a backdoor access system into Gmail accounts. This feature is what the Chinese hackers exploited to gain access.' His article is short on sources, and the common belief is that a flaw in IE was the main attack method. Has this come up elsewhere? Schneier continues, 'Whether the eavesdroppers are the good guys or the bad guys, these systems put us all at greater risk. Communications systems that have no inherent eavesdropping capabilities are more secure than systems with those capabilities built in. And it's bad civic hygiene to build technologies that could someday be used to facilitate a police state.'"

    His article is short on sources

    Agreed so I visited his blog and a recent post is equally scant. He points back to another blog post with a little more but really he's just pointing out the irony of a new proposed bill outlawing Google's collaboration with China in violating human rights issues. The irony being that the US has asked for similar backdoors from Google already.

    So here's my problem: More frequently Schneier acts as a reputable news source 'breaking' a story without citing the originator of the information. This is fine when it's a big paper like the New York Times but Schneier runs a blog on security. That's it. He might be a first hand expert but if so why isn't he showing and describing his conclusive evidence that the US mandated backdoor is how Chinese hackers gained entry? There's no doubt the software is less secure with a backdoor -- by definition -- but when he says:

    In order to comply with government search warrants on user data, Google created a backdoor access system into Gmail accounts. This feature is what the Chinese hackers exploited to gain access.

    He better be able to back it up. And he reiterates:

    China's hackers subverted the access system Google put in place to comply with U.S. intercept orders.

    I just want to caution everyone that you're reading an opinion piece by a security blogger with no corroborating evidence. And on top of that, he has zero accountability. In fact, he says none of this on his blog, he leaves it as an op-ed on CNN. Read it like a strange click generating opinion piece and nothing more.

    I have respect for the man but this certainly shakes that. Any concrete proof of this would be welcomed. The problem is I'm not sure how one would prove it one way or the other since I believe all the source in question is closed source to begin with.

And it could be that US operations didn't know about it, Google China is its independent operation after all and why they're maybe pulling off.

      This supposition just raises more questions in my mind though. 1) What do you mean by "independent operation" because it's still a subsidiary of Google and I'm sure utilizes much of the exact replicated technology. 2) Why in the world would Google enforce an American law in China? 3) If Google were providing this intercept data as access to the Chinese government then why in the hell would the Chinese government break in to steal email data from human rights activists? (From the original source, they suspect it was the government because the target was 'accessing the Gmail accounts of Chinese human rights activists') Why would the government need to gain malware access to the system that's put in place for them to access?

      I think it was AT&T or Verizon that we had /. article recently about how US government used their backdoor tons of times to gather info and that it would had been impossible to handle manually. Why wouldn't Google, one of the largest US companies, have similar system?

      All big time communications operations have to worry about this. It sucks but it's the law. The question remains, however, what is that doing in China and if they're doing it for Chinese law, why did the government need to hack their own system set up to serve them?

If they go after him, then you have a tell tale sign. If there are code changes, again, tell tale sign. If he gets harrassed or hammered by 3 letter agencies, again, tell tale (and maybe this has already happened).

His hands may be tied in this case or he's being careful (esp. with a new administration that still has strong ties in the agencies to the prior administration, with a pro-prosecutional bent to it to go after small fries which Schneier would be in the grand scheme of things in the populace).

Then it is quite commonplace that soon you see exact copies of your camera appear in the shops, with the exact same specifications and quality, just a lot cheaper. And it can very well be that those copies are made in your own factory in a second shift, after they are done producing your own orders.
