The Update That Waited
United Kingdom2017
In May 2017 the ransomware WannaCry hit computers all over the world, including the British health service, the NHS. The virus used a hole in Windows for which an update already existed, and the NHS had warned in March and April to install it. The British investigation estimates that more than 19,000 appointments were cancelled. The costs were later estimated at 92 million pounds. The characters in this puzzle are made up. The attack is real.
What can you learn?
Updates exist for a reason: they close holes that hackers crawl through. Do not put them off, and turn on automatic updates on your phone, tablet and computer.
This does not give away who the weak link in the puzzle is: the characters are made up.
