Hackers in China gained access to information about the operations of the U.S. Chamber of Commerce and its three million members, according to a Wall Street Journal report. The report says hackers may have enjoyed access to Chamber information for a whole year before being uncovered and shut down in May 2010. Quoting unidentified sources familiar with the incident, the Journal says the group behind the hacking is suspected of having ties to the Chinese government and that the FBI alerted the Chamber of Commerce about the breach. The Chamber is the top American business lobbying group, whose members includes most of the U.S. largest corporations. A spokesperson from the Chinese Foreign Ministry dismissed the report, calling it baseless.
