London: Russia was behind hostage software

Britain has openly accused Russia Thursday of an attack with host-free software NotPetya.

'The decision to name the perpetrator underlines the fact that Britain and its allies do not accept malicious cyber activities,' the London Foreign Office said. According to the ministry, the attack was the work of the Russian army.

NotPetya, also often called Petya, spread through a Ukrainian accounting program. Computer systems have been shut down all over the world. 'The reckless use disrupted organizations across Europe, which cost hundreds of millions,' according to the foreign minister, Tariq Ahmad. The attack was soon attributed to Russia.
