Solid Oak, however, is not the only company under attack for its involvement with Green Dam. The English-language China Daily said last week that Jinhui had received more than 1,000 death threats since the government's filtering rule was first reported earlier this month.
After three University of Michigan researchers identified security flaws and copied code in Green Dam, the Chinese government directed the makers of Green Dam to fix the security vulnerabilities, according to a report in the English-language China Daily.
But according to a June 25 report published by Solid Oak, the most recent release of Green Dam (v3.17) still contains four files from CYBERsitter. The copied files are not merely lists of sites to be blocked, the report alleges, they also contain programming code.
"Contrary to statements made by Green Dam's developer that these were just 'lists of international pornographic sites,' the code lines shown above are code snippets that tell CYBERsitter (and Green Dam) how to handle word combinations when found in URLs, search queries, or page content," the report says.
Solid Oak has advised Dell and HP that they face legal liability if they comply with the Chinese government mandate and ship PCs with Green Dam.
The U.S. government last week lodged a formal protest of the Green Dam mandate. Chinese authorities did not respond directly. However, the Chinese Ministry of Health's decision on Friday to issue new anti-pornography rules affecting sex education sites suggests that Chinese authorities intend to resist public pressure.
