A global cyber attack leveraging hacking tools believed to have been developed by the U.S. National Security Agency has infected tens of thousands of computers in nearly 100 countries, disrupting Britain’s health system and global shipper FedEx.

Cyber extortionists tricked victims into opening malicious malware attachments to spam emails that appeared to contain invoices, job offers, security warnings and other legitimate files.

The ransomware encrypted data on the computers, demanding payments of $300 to $600 to restore access. Security researchers said they observed some victims paying via the digital currency bitcoin, though they did not know what percent had given in to the extortionists.

Researchers with security software maker Avast said they had observed 57,000 infections in 99 countries, with Russia, Ukraine and Taiwan the top targets.

Asian countries reported no major breaches on Saturday, but officials in the region were scrambling to check and the full extent of the damage may not be known for some time.
The most disruptive attacks were reported in Britain, where hospitals and clinics were forced to turn away patients after losing access to computers on Friday.

International shipper FedEx Corp said some of its Windows computers were also infected. “We are implementing remediation steps as quickly as possible,” it said in a statement.
Within hours, over 75,000 attacks have been detected worldwide, the company said. Meanwhile, the MalwareTech tracker detected over 100,000 infected systems over the past 24 hours.

Security researchers with Kaspersky Lab have recorded more than 45,000 attacks in 99 countries, including the UK, Russia, Ukraine, India, China, Italy, and Egypt. In Spain, major companies including telecommunications firm Telefonica were infected.
The ransomware is a type of malicious software that infects a computer and restricts users’ access to it until a ransom is paid to unlock it. It demands users pay USD 300 worth of cryptocurrency Bitcoin to retrieve their files, though it warns that the payment will be raised after a certain amount of time. The malware spreads through email.
