PCWorld is reporting that chinese hackers appear to be preparing for an attack on CNN scheduled for April 19. The attack is being spurred by the recent pro-Tibet coverage in the media. A Chinese site called Anti-CNN is protesting what it considers anti-Chinese propaganda and is calling for protests in several countries including Germany, France and the UK. The hackers, believed to be members of The Red Hat Alliance, are calling for a DDos (Distributed Denial of Service Attack) against CNN to coincide with the protests. It is not yet known if the group is capable of backing up its attack threats, but security firms and media outlets will be watching closely to find out.
