Anonymous, the nebulous online activist group that uses hacking to further causes it supports, has threatened a major blackout of Chinese and Hong Kong government websites, and to leak tens of thousands of government email address details.
The group, under the banner of "Operation Hong Kong" or #OpHongKong and #OpHK on Twitter, said on Friday it will launch a mass effort against Chinese government servers to bring down their websites via Distributed Denial of Service (DDoS) attacks on Saturday.
DDoS attacks attempt to cripple networks by overwhelming them with Internet traffic.
