The International Monetary Fund is investigating a serious hacking attempt on its networks, according to several reports.
The organisation, which holds extremely confidential information on the economic health of its 187 member countries, confirmed on Saturday that an intrusion took place and that it is investigating this. Although the IMF has not released details about the scope of the incident, the organisation suffered a "very major breach", a senior official at the fund told The New York Times.
The hacking lasted for several months, but ended before the arrest of former IMF managing director Dominique Strauss-Kahn in mid-May, the official added.
The IMF told staff about the intrusion on Wednesday. In a memo, the fund said a desktop computer had been hacked and used to access other IMF systems, Bloomberg reported. As a result, the network connection between the IMF and the World Bank was unplugged.
In addition, the IMF's staff were told that their RSA SecurID tokens would be replaced, though the memo said there were no indications at the moment that the tokens were used in the attack. The organisation also seems to have ruled out cybercriminals and the Anonymous group as culprits, suggesting that the targeted attack may have been undertaken by a foreign government.
