The virus took control of users’ files and demanded the payment of bitcoins, The UK and Russia were among the worst-hit countries with the 48 NHS trusts reported problems at hospitals, GP surgeries or Pharmacies. As on 10:30am on Monday morning only 7 hospitals are still experiencing problems. ### **How has this happened? ** The ransomware strain WannaCry has exploited a Microsoft Windows vulnerability, the software known as EnternalBlue which is a tool helped to create the attack which was stolen or leaked from the NSA by a hacking group in April. Microsoft released a security patch in March to patch the vulnerable issue however many corporations don’t automatically update their systems. ### **Are personal computers at risk?** Anyone who runs Windows on their personal Computers/laptops and HASN’T run the latest update is at risk. Microsoft said it has taken the ‘Unusual step’ of releasing a patch for older operating systems such as Windows XP, Windows 8 and Windows 2003. This means anybody who runs these should update them. ### **Who is behind the attack?** The hackers have remained anonymous, they have demanded payment of 300 bitcoins for the return of information. The attack wasn’t specifically targeted at the NHS and has hit a variety of businesses and personal computers around the world, their motives are unknown. ### **What happens next?** If you haven’t been affected, then make sure you update your windows PC as soon as possible. If you have been affected, then unless you have a back-up of your files your only choice is to pay the bitcoin being demanded. Experts are considering ways of finding a weakness in WannaCry that allows them to decode the ransomware without paying but they have had no luck yet.
