Last week, US broadcaster CNN was targeted in a dedicated denial of service (DDoS) attack intended to interrupt its news website. The attack was repelled "resulting in countermeasures that caused the service to be slow or unavailable to some users in limited areas of Asia", CNN reported.
In a DDoS attack, hackers flood a targeted website with thousands of automated requests for service in order to jam the works.
CNN has been accused of skewing its news coverage of the crackdown in Tibet to cast China in a negative light in the lead up to the summer Olympic Games.
CNN commentator Jack Cafferty further inflamed the situation when earlier this month, he labelled Chinese goods "junk" and its leaders a "bunch of goons and thugs".
Scott Henderson, a former US Army intelligence analyst who wrote a book about Chinese hackers called The Dark Visitor, has been tracking developments on his blog and says that what's happened over the past week may be the opening salvo in new cyber war.
This has been going on for awhile in the U.K. as well.
