South Korean officials are scrambling to restore order to its IT infrastructure today after a series of cyber attacks left a number of major companies and services with their servers down. Three television broadcasters, KBS, MBS and YTN, and two banks, Nonghyup and Shinhan Bank, all reported that their networks had suddenly given way on Wednesday afternoon. Staff at the TV stations said their computers completely shut down and could not be restarted, while some claimed skulls appeared on their screens – suggesting the injection of malicious code rather than a denial of service attack as was initially suspected.

The USPTO's decision has stimulated a heated discussion over whether such far-reaching patents are in the wider interest of innovators and their ideas. Is it squeaky bum time for Mark Zuckerberg and his cohorts? Will Twitter's success serve to spur on or stifle future social technologies? Follow the link and join the debate…
