Huge 'Petya' cyber attack spreading across the world in potential repeat of 'Wannacry' hack

A huge cyber attack that initially hit Ukraine appears to be spreading across the world. The hack was already the biggest in Ukraine's history when it hit that country. But it appears to be making its way to other countries – including Spain and India – and may be functioning like the massive "Wannacry" attack, according to cyber security experts. The attack is hitting major infrastructure in the countries where it has spread to. That has included companies ranging as widely as Danish shipping company Maersk and British advertising company WPP.
