London/Madrid: A major cyber attack has struck globally and has supposed to have infected thousands of computers all over the world. These leveraging hacking tools are supposed to have been developed by the U.S. National Security Agency and has infected as many as tens of thousands of computers in nearly 100 countries.
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.
