Global ‘Ransomware’ Attack Believed to Be Using Leaked NSA Hacking Tools

(Reuters) — A huge cyber attack leveraging hacking tools widely believed to have been developed by the U.S. National Security Agency brought disruption to Britain’s health system on Friday and infected dozens of other countries around the world, security researchers said.

Hospitals and doctors’ surgeries in parts of England were forced to turn away patients and cancel appointments after they were infected with the “ransomware”, which scrambled data on computers and demanded payments of $300 to $600 to restore access. People in affected areas were being advised to seek medical care only in emergencies.

“We are experiencing a major IT disruption and there are delays at all of our hospitals,” said the Barts Health group, which manages major London hospitals. Routine appointments had been canceled and ambulances were being diverted to neighboring hospitals.

Telecommunications giant Telefonica was among many targets in Spain, though it said the attack was limited to some computers on an internal network and had not affected clients or services.
