  • US surveillance agency may be using Google's advertising cookies to track and "pinpoint" targets for government hacking and location-tracking. According to Snowden's leaked presentation slides, both the NSA and the British equivalent, the GCHQ, are using a Google-specific ad cookie (know as "PREF") as a way of homing in on specific surveillance targets. While Google's cookie doesn't contain personal information like a name or email address, it does contain numeric codes that uniquely identify a user's browser.
  • The report notes that the NSA doesn't use this technique to find suspicious activity amidst the massive flood of internet communication that takes place every day — instead, it uses it to home in on targets already under suspicion.

  • Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA. The attack can extract full 4096-bit RSA decryption keys from laptop computers (of various models), within an hour, using the sound generated by the computer during the decryption of some chosen ciphertexts. We experimentally demonstrate that such attacks can be carried out, using either a plain mobile phone placed next to the computer, or a more sensitive microphone placed 4 meters away.

    When I first read the article, I though it would take some sensitive mics but, quoting the article "Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA.

Kurt Eichenwald Claims Snowden Is A Chinese Spy And Leaks Are Just To Protect Their Cyb... - 0 views

2013 chinese attacks cyber indienationnews Snowden Eichenwald

  • And the attempts to tar and feather Ed Snowden continue. The latest is that famed reporter Kurt Eichenwald, who started attacking Ed Snowden months ago, has written up a long speculative article for Newsweek arguing that Ed Snowden has "escalated the cyber war" by giving China the necessary cover it needs to avoid reining in its own cyber attacks
  • That is, if you follow the bizarre logic here, without Snowden, Eichenwald believes that the US would have somehow convinced the Chinese to stop their cyber attack program. And, now because of Snowden, the Chinese can ignore that effort, by pointing out that the US is doing a ton of online hacking too.
  • Again, nearly everything about that statement is ridiculous. He didn't "leave all of the documents in Hong Kong." He provided heavily encrypted versions to a very small number of journalists, and then got rid of the files himself. Eichenwald takes that to mean he "left" them in Hong Kong, based on nothing, and all of this apparently means that Snowden is working for the Chinese (even though he left China pretty quickly).
