The WannaCry virus attack wreaked havoc in
mid-May as it hit over 200,000 computers world-wide. The virus affected
computers in 150 countries across North America, Europe and Asia, and
the attack was the largest ransomware delivery campaign till date.
The National Health Service (NHS) in the UK was affected. Critical
medical procedures had to be postponed, hospitals were unable to admit
patients, and ambulances had to be diverted to other hospitals. Doctors
had to briefly go back to pen and paper. In China, college and
university students found their data encrypted by the virus. In Germany,
the railway was affected, as was one of the largest mobile companies in
Spain, Telephonica. The virus made its way to numerous other industries
and businesses around the world.
