U.S. Chamber of Commerce - 2011
Hackers in China were able to breach the computer system of the United States Chamber of Commerce. The hackers had access to the information of roughly three million members from November 2009 to May 2010. Though the breach was discovered in May of 2010, there is evidence that some systems were still compromised in March of 2011. Email communications with no more than 50 of the Chambers' members were compromised. Company names, key company contacts, trade-policy documents, meeting notes, trip reports, and schedules were in the email communications.
