Worming Our Way Out of Trouble

The Conficker worm will be active again on April 1st, according to an analysis of its most recent variant, Conficker.C, by the net security firm CA. This malicious piece of software, also known as Downup, Downadup and Kido, spreads among computers running most variants of the Windows operating system and turns them into nodes on a multi-million member ‘botnet’ of zombie computers that can be controlled remotely by the worm’s as yet unidentified authors. more

He also said that cybersecurity will be one of the main focuses of his tenure at the Pentagon.

Digital Geneva Convention: Multilateral Treaty, Multistakeholder Implementation

Microsoft's call for a Digital Geneva Convention, outlined in Smith's blog post, has attracted the attention of the digital policy community. Only two years ago, it would have been unthinkable for an Internet company to invite governments to adopt a digital convention.

Over the last year the world has been virtually buried under news items describing hacks, insecure websites, servers and scada systems, etc. Each and every time people seem to be amazed and exclaim "How is this possible?"
