The International Monetary Fund has become the latest high-profile organization to fall victim to a network intrusion, according to various media reports, suffering a substantial breach, the full extent of which is not yet known.

IMF spokesman David Hawley said the organization is fully functional, but declined to provide further details on what he termed an “IT incident.” Hawley also declined to say if data was taken.

Bloomberg quoted what it said was a memo sent to IMF employees on Wednesday by the organization’s chief information officer warning staff to be vigilant:

“Last week we detected some suspicious file transfers, and the subsequent investigation established that a Fund desktop computer had been compromised and used to access some Fund systems. At this point, we have no reason to believe that any personal information was sought for fraud purposes.”

Just this week banking giant Citibank confirmed that credit card data of about 200,000 of its North American customers have been hacked. The event marked the largest attack on a bank in the US to date.The week before US military contractor Lockheed Martin was compromised as hackers used Lockheed’s own “secure id” technology to access its networks.
Bloomberg reported that the Wednesday memo said the breach was not associated with the group Anonymous, which had earlier threatened an attack on the Fund in association with IMF activities involving the economically hobbled country of Greece. Yesterday, law enforcement officials in Spain said they had arrested several members of Anonymous in connection with attacks on entertainment giant Sony, as well as on governments and financial institutions.
