Banks in London, New York to Test Security in Cyber War Game

Banks in London and New York will simulate a massive cyber attack on their computer systems later this year as part of joint war games run by the U.S. and U.K. governments.

The exercise, designed to test the institutions’ resilience, is part of a new program of cooperation against cyber-crime and terrorism in the wake of the hacking of Sony Corp. last year. The U.S. has blamed North Korea for the attack, which led to internal documents being posted online.
