(LONDON) — A huge extortion cyberattack hit dozens of nations Friday, holding computer data for ransom at hospitals, telecommunications firms and other companies. The attack appeared to exploit a vulnerability purportedly identified for use by the U.S. National Security Agency and later leaked to the internet. The attack hit Britain's health service, forcing affected hospitals to close wards and emergency rooms. Related attacks were reported in Spain, Portugal and Russia.
