On January 12, 2010, Google announced that it was "no longer willing to continue censoring" results on Google.cn, citing a breach of Gmail accounts of Chinese human rights activists including thousands of activists involved with the Human Rights Defender, Falun Gong, and hundreds of overseas activists in fields such as encryption, intellectual property and democracy. The company learned that the hackers had breached two Gmail accounts but were only able to access 'from' and 'to' information and subject headers of emails in these accounts. The company's investigation into the attack showed that at least 34 other companies had been similarly targeted, including Adobe Systems, Symantec, Yahoo, Northrop Grumman and Dow Chemical. Experts claimed the aim of the attacks was to gain information on weapon systems, political dissidents, and valuable source code that powers software applications. Additionally, dozens of Gmail accounts in China, Europe, and the United States had been regularly accessed by third parties, by way of phishing or malware on the users' computers rather than a security breach at Google. Although Google did not explicitly accuse the Chinese government of the breach, it said it was no longer willing to censor results on google.cn, and that it would discuss over the next few weeks "the basis on which we could run an unfiltered search engine within the law, if at all. We recognize that this may well mean having to shut down Google.cn, and potentially our offices in China".
