The World Bank Group's computer network — one of the largest repositories of sensitive data about the economies of every nation — has been raided repeatedly by outsiders for more than a year, FOX News has learned.

It is still not known how much information was stolen. But sources inside the bank confirm that servers in the institution's highly-restricted treasury unit were deeply penetrated with spy software last April. Invaders also had full access to the rest of the bank's network for nearly a month in June and July.

In total, at least six major intrusions — two of them using the same group of IP addresses originating from China — have been detected at the World Bank since the summer of 2007, with the most recent breach occurring just last month.

In a frantic midnight e-mail to colleagues, the bank's senior technology manager referred to the situation as an "unprecedented crisis."
