Politically provoked DDoS attacks on the increase...

The perpetrators at this stage are unknown, although Phayul.com is an independently run and self reliant news portal of the Tibetan community. This is another perfect example of the increasing infringement on freedom of speech.

Politically provoked DDoS attacks

A new computer Trojan named Vecebot is a new malware family and has been associated to denial of service (DDoS) attacks against bloggers who have posted critical comments against the ruling Communist Party and Chinese mining operations in the nation, as reported by ThreatPost on October 29, 2010.
According to the analysis, targets of the Vecebot botnet were estimated somewhere between 20,000-30,000 hosts. These hosts included some of the famous blogs and online forums of Vietnam. Further, as per the analysis, the launch of Vecebot might have been synchronized with the "Vietnam Blogger Day" on October 19, 2010, an online civil action to commemorate the launch of a blogger and political detainee who exploited the name Dieu Cay.
