The attack appears to have affected a number of organisations in several countries. Ransomware, which demands payment after launching a cyber attack, has become a rising trend among hackers.
A global cyberattack " WannaCry Ransomware " leveraging hacking tools widely believed by researchers to have been developed by the U.S. National Security Agency hit international shipper FedEx, disrupted Britain's health system and infected computers in nearly 100 countries on Friday.
Russian cyber security software maker Kaspersky Lab said its researchers had observed more than 45,000 attacks in 74 countries as of early Friday. Later in the day, security software maker Avast put the tally at 57,000 infections in 99 countries. Russia, Ukraine and Taiwan were the top targets, Avast said.

Among the organisations affected are Britain's National Health Service, the Spanish telecommunications firm Telefónica, and the logistics firm FedEx.
The cyberattack has caused chaos across the United Kingdom. Hospitals have been closed and operations cancelled on short notice, and medical staffers have resorted to pen and paper to do work.
Both NHS and Telefónica confirmed the attacks. They said they had been hit by versions of the so-called WannaCry ransomware that demands at least $300.
