Liu took part in the Tiananmen protests in 1989 and was a leading author of Charter 08, a manifesto demanding basic human rights and political reform in China that was published on Dec. 10, 2008, the 60th anniversary of the United Nations’ Universal Declaration of Human Rights.
Findings by the Norman malware detection team in Oslo revealed a new Trojan-horse virus was transmitted through vulnerability in Firefox versions 3.5 and 3.6, enabling the attacker to have access to infected computers. A Trojan is a malicious software (malware) that allows unauthorized access to a user's computer, most often to steal secrets such as passwords and financial information.
Mr. Walton, who studied virus samples of Trojan horses in 2008 that were targeting Tibetan activists, said yesterday's virus originated from Taiwan, but was probably used a “stepping stone” from mainland China.
He added that the virus was probably meant only to send a signal because it did not deface the website. By doing that, he said, the hacker emphasized that it wanted to “harvest the social graph of people using the website.”
