This malware not only attacks the client computers but also attacks the computer – the server computer where important data is owned by the agency being attacked.

Repeat, always backup important file files on your computer and save the backup elsewhere

Actions After Infection:

Currently there is no quickest and most accurate solution to restore files that have been infected with wannacry. However, disconnecting the internet connection from an infected computer will stop the spread of wannacry to other vulnerable computers. beware of this threat by doing the following:

In order for PCs and other forms of Personal Computers and Networks do not connect to LANs and the Internet first,

CHAPTER III

COVER

3.1 Conclusions

Wannacry infects a computer by encrypting all the files on the computer and by using weaknesses in the SMB service can execute commands and then spread to other Windows computers on the same network. All computers connected to the internet that still have this disadvantage especially computers that are on the same network have the potential to be infected with the threat of Wannacry.

3.2 Suggestions

This ransomware virus has spread throughout the world, so it’s good and should have been prevented before getting infected. Because if it has been affected, the files in the computer will be helpless in other words, it cannot be opened.
