The WSJ, along with The New York Times, Washington Post, Bloomberg and others, revealed last week that they were the targets of Chinese hackers. The hackers had infiltrated the publications' computer systems in an attempt to gain access to information relating to their coverage of China.
The WSJ also wrote a scathing editorial aimed at the Chinese government:
"[W]hatever else the Chinese thought they were doing by hacking us, they didn't stop the publication of a single article. Now they have only magnified their embarrassment, as their intrusion was eventually bound to be detected and publicized.
