Today's Tech: China fires back at "groundless" US accusations, Skype hit by "Dorkbot" malware, & RSA Conference Europe 2012

China hit back at claims that American companies should stop doing business with leading Chinese telecoms firms Huawei and ZTE today, following a recent report by the US House of Representatives' Intelligence Committee that warned the Far East manufacturers could be compromising national security interests. The regime responded to the findings by calling them "groundless accusations based on subjective suspicions" and appealed to America to set aside its prejudice against Chinese firms or risk strained diplomatic relations in the future.

Elsewhere, Newcastle University and Microsoft's R&D facility in Cambridge have given birth to an interesting new piece of technology dubbed 'Digits." The gadget maps 3D finger movements via a minute camera, recognising specific gestures, which it can then translate into remote commands directed at any device connected to it - think Minority Report but with multiple devices responding to a single wave instead of a lone programmed screen. Furthermore, the device does not need to be within direct sensor range, making it a truly mobile form of control. Scientists are already formulating possible applications for 'Digits', with television remotes, games controllers, and even cash machines potentially featuring in future deployment scenarios. A Jedi wave helping you access your money - what's not to love?

Another day, another ITProPortal journalist getting their hands dirty at a key technology event. Today was the turn of our resident security expert Will Dalton, who dutifully descended on the London Hilton Metropole hotel to take in the opening keynote speech of RSA Conference Europe 2012. There's rarely a dull moment in the Bond-esq world of digital security, and RSA Executive Chairman Art Coviello certainly didn't disappoint the assembled industry dignitaries, venting his frustrations about privacy advocates in an impassioned address. Specifically, he said that persistent "cries of Big Brother" were preventing more stringent security measures from being implemented, hampering the experts' ability to fully protect citizens online. Do the digital bouncers have a point?

Speaking of security, VoIP service Skype has become the latest victim of cyber criminals, who are employing social engineering to tempt users into following a link and unintentionally downloading "Dorkbot," a worm that infects Windows PCs. The malware has the ability to lock users out of their computers, hold infected machines to ransom, or conscript them into a botnet army. By avoiding unusual links from Skype contacts, "Dorkbot" can be kept at bay, but for those of us unlucky enough to have been caught out, Skype has published instructions on how to get rid of the worm.
