Hackers in China are believed to have broken into the servers of the U.S. Chamber of Commerce.
According to a report published by the Wall Street Journal, attackers gained access to "everything" stored on the servers, including information about the Chamber's three million members.
While it was not clear how severe the breach was and what information was extracted, the Journal said that the attack may have lasted for more than a year and was among the boldest moves in an ongoing confrontation and involved "at least 300 Internet addresses." It was uncovered and shut down in May 2010. Apparently, the FBI notified the Chamber that China was stealing its information. Not surprisingly, China said that it had no idea that the attack occurred, that there was no evidence for the allegations and any accusations are irresponsible.
"What was unusual about it was that this was clearly somebody very sophisticated, who knew exactly who we are and who targeted specific people and used sophisticated tools to try to gather intelligence," the Chamber's Chief Operating Officer David Chavern told the WSJ. The Chamber believes that communications with fewer than 50 of its members were compromised. The information provided to the newspaper indicated that the breach used tools that enabled the attackers to "search for key words across a range of documents on the Chamber's network, including searches for financial and budget information."
