Hackers have unleashed a major cyber attack causing huge disruption to companies and governments across the globe including in the UK, US and Russia.
The Petya ransomware hijacks victims’ computers before encrypting their files and holding them hostage until a fee is paid.
Chernobyl’s radiation monitoring system has been hit by the attack with its sensors shut down while UK advertising giant WPP, the largest agency in the world, among dozens of firms affected.
The ransomware appears to have been spread through popular accounting software and specifically targeted at bringing down business IT systems.
The outage began in Ukraine as the country’s power grid, airport, national bank and communications firms were first to report problems, before it spread rapidly throughout Europe.
Companies in the US, Germany, Norway, Russia, Denmark and France are among those to have confirmed issues so far.
