PCWorld is reporting that Chinese hackers appear to be preparing for an attack on CNN scheduled for April 19th. 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 attack threat however, appears to be unrelated to the Anti-CNN site. The hackers, believed to be members of The Red Hat Alliance, are calling for a DDoS 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. It's quite possible one of the many botnets thriving on the net may be used to carry out such an attack. So far, CNN has not had any comment on the threat made against their website.
