A massive ransomware campaign appears to have infected a number of organizations around the world. Screenshots of a well-known program that locks computers and demands $300 (£230) in Bitcoin have been shared online by parties claiming to be affected. There have been reports of infections in the UK, US, China, Russia, Spain, Italy, Vietnam, Taiwan and others. Security researchers are linking the incidents together.
