Security experts suspect government involvement may have played a role in a recent hacking of the International Monetary Fund’s computer system. Although the IMF hasn’t released enough information about the hack to be certain, experts say the sophisticated nature of the attack and the resources required to execute it indicate a nation-state was involved. They believe the hacker installed software on a single computer that sent scam e-mails to specific victims. An internal IMF memo said “suspicious file transfers” were detected. If experts’ suspicions turn out to be correct, the incident wouldn’t be the first example of state-sponsored hacking in recent months. The Chinese government was recently accused of hacking Gmail accounts of hundreds of US officials, military personnel and journalists.
