The WannaCry ransomware attack is an ongoing cyber-attack of the Wanna Cry ransomware computer worm targeting the Microsoft Windows operating system. The attack started on Friday, 12 May 2017, infecting more than 230,000 computers in 150 countries, with the software demanding ransom payments in the cryptocurrency Bitcoin in 28 languages.

Bitcoin is a cryptocurrency and a digital payment system invented by an unknown programmer, or a group of programmers, under the name Satoshi Nakamoto. It was released as open-source software in 2009.

The system is peer-to-peer, and transactions take place between users directly, without an intermediary. These transactions are verified by network nodes and recorded in a public distributed ledger called the block chain. Since the system works without a central repository or single administrator, bitcoin is called the first decentralized digital currency.
