The Intercept published an expose on the NSA's XKeyscore program. Along with information on the breadth and scale of the NSA's metadata collection, The Intercept revealed how the NSA relies on unencrypted cookie data to identify users. As The Intercept says: "The NSA’s ability to piggyback off of private companies’ tracking of their own users is a vital instrument that allows the agency to trace the data it collects to individual users. It makes no difference if visitors switch to public Wi-Fi networks or connect to VPNs to change their IP addresses: the tracking cookie will follow them around as long as they are using the same web browser and fail to clear their cookies." The NSA slides released by The Intercept give detailed guides to understanding the data transmitted by these cookies, as well as how to find unique machine identifiers that analysts can use to differentiate between multiple machines using the same IP address. We've written before about how spy agencies piggyback on social media account data to find Internet users' names or other identifying info, and these slides drive home the point that HTTP cookies leave users vulnerable to government surveillance, since any intermediary (or spy agency) can read the sensitive data they contain.

Worse yet, most of the time these identifying cookies come from third-party sources on webpages, and users have no meaningful way to opt out of receiving them (short of blocking all third party cookies) since advertisers (the main server of these types of cookies) refuse to honor the Do Not Track header.  Browser makers could help address this sort of non-consensual tracking by both advertisers and the NSA with some simple technical changes—changes that have been shown to reduce the number of third party cookies received by 67%. So far, though, they've been unwilling to build privacy protecting features in by default. Until they do, the best way for users to protect themselves is by installing a privacy protecting app like Privacy Badger, which is designed to block these types of uniquely identifying tracking cookies, or HTTPS Everywhere to block the transmission of HTTP cookies.

Microsoft today launched a deathwatch for its 10-year-old Internet Explorer 6 browser, saying it wanted to "see IE6 gone for good." According to Microsoft, which cited statistics from Web analytics firm Net Applications, IE6 still has a 12% global usage share, with almost half of that in China, long a stronghold of the aged browser. Microsoft wants to drive IE6's share under 1%.

Because HTML 4.0 essentially was a "frozen" version, the specific mechanism for displaying content has been very much format dependent (e.g., Apple QuickTime Movies and Flash video) and usually relies upon tags with varying parameters for passing the relevant information to the server. As a result, video and audio embedding on web pages has become something of a black art . Its perhaps not surprising then that the <audio> and <video> tags were among the first features to be added to the HTML 5 specification, and these seem to be the first elements of the HTML 5 specification that browser vendors implemented. These particular elements are intended to enable the browser to work with both types of media in an easy-to-use manner. An included support API gives users finer-grained control.

Theoretically, the <video> and <audio> elements should be able to handle most of the codecs currently in use. In practice, however, the browsers that do currently support these elements do so only for the open source Ogg Vorbis and Theora standards.

Makes email “scary” in order to disrupt NSA surveillance Install Visit the Install ScareMail page to setup ScareMail on your preferred browser. Introduction ScareMail is a web browser extension that makes email “scary” in order to disrupt NSA surveillance. Extending Google’s Gmail, the work adds to every new email’s signature an algorithmically generated narrative containing a collection of probable NSA search terms. This “story” acts as a trap for NSA programs like PRISM and XKeyscore, forcing them to look at nonsense. Each email’s story is unique in an attempt to avoid automated filtering by NSA search systems.
