NHS/Cyber attack case study

NHS/Cyber attack case study

1. Ransomware- Malware which demands money to be paid.

   • Wants to be payed via Bitcoin
     • Payed electronically from and to electronic bitcoin wallets.

2. Encryption

   • Asymmetric as it is the hardest to break and retrive data.
     • You would need the private key in order to decrpyt the data but the hackers have it so they want you to pay for it

3. Spread through attachments and emails

   • Email server
   • Also spreads through P2P networks e.g. file sharing

4. back up files on internal or external storage

   • Keep your software and computer up to date to protect yourself from this malware

5. Very similair to Cryptolocker as it encrypts the files and produces a lock screen/change background to say that they have been affected by the ransomware
