12/5/2017, A massive cyber-attack, the biggest in the world to date, hit almost 100 countries across the world. Computers were hit by ransomware, which encrypted their files and users could not recover them without paying several hundred pounds in Bitcoin. In the UK the NHS was badly affected; a vulnerability factor was the continued use of outdated software. The attack combined features of ransomware with a worm that enabled it to spread within computer networks. The identity of the attacker remains unknown.

Charles Babbage had designed and partially built a mechanical ‘Analytical Engine’ between 1821 and 1871. The 1889 computer was designed to compute the results of the 1890 census, using punched cards. The inspiration for this machine came from a scheme on the US railways to enter the physical details of every passenger on their ticket by means of a punched hole card system – so that train robbers could be identified when they posed as ordinary travellers. The railway sceheme did not win wide acceptance.
