It also found that dozens of other Gmail accounts owned by human rights activists worldwide were compromised, most likely due to phishing scams or malware.

Google wouldn’t say it, but implications are that the Chinese government had something to do with these attacks.

As a result of the attacks, Google has decided to reassess its presence in China.

"These attacks and the surveillance they have uncovered–combined with the attempts over the past year to further limit free speech on the web–have led us to conclude that we should review the feasibility of our business operations in China.

We recognize that this may well mean having to shut down Google.cn, and potentially our offices in China."
