Today's Tech: Apple buying Kinect designers PrimseSense, the NSA sowing malware on the world, and the Racing Post data breach

In another of its series of sneaky moves, Apple has confirmed its purchase of PrimeSense, the Israeli company behind the Xbox's revolutionary Kinect add-on. The characteristically laconic announcement has ended a week's speculation about the deal, but we still haven't got any answers about what the Cupertino-based company wants to do with its Tel Aviv-based acquisition. Motion sensors on the iPhone? An Apple games console? No one knows, and Apple sure ain't telling.

Speaking of sneaky, today saw another in the almost endless line of revelations about everyone's least favourite three-letter spy agency. Dutch newspaper NRC Handelsblad is reporting that the American National Security Agency (NSA) infected more than 50,000 computer networks with a particularly devious cocktail of malware in a process known as "Computer Network Exploitation." These "implants," as they're known by the NSA, are deployed by a department within the agency called Tailored Access Operations (TAO). Software engineers within TAO allegedly broke into various routers, switches, and firewalls in an effort to compromise networks and gain access to the data being transmitted. So we've finally answered the question of what happens if a government gives a spy agency more money than it even wants, and relaxes all regulation on its activities.

Prominent online gambling and horse racing website Racing Post has revealed that it suffered a massive data breach over the weekend after "a sophisticated, sustained and aggressive attack" on its networks. In response to the breach, Racing Post assured users that it is currently reviewing all of its security measures and would be putting in "even stronger protection" to prevent this from happening again. "Extensive changes have already been made overnight with the assistance of industry-leading cyber-security experts," it said in an email to all of its customers. The company warned that while passwords were encrypted, some of the details could be used for identity theft. For this reason, any users who use similar passwords on other websites and decline to change them could be gambling on more than just the races.
