World Bank's several servers were intruded several times over the last one year period. The originating ip addresses were traced back to China. But the blame for the keylogger(A spyware which sends all typed key strokes to the hacker) itself was on india's satyam computers.
An independant security firm which conducted investigation submitted its report to World Bank and has indicted one of the contractors of satyam responsible for the spyware. Though the spyware itself was installed as a result of carelessness of the contractor, it is hard to believe whether World Bank will award any future projects to Satyam.
World Bank has already signed deals with two other indian it majors to take over from Satyam.The likely companies are tcs,infosys or wipro.
