Utilize a whitelisting program. Application control or whitelisting plans quit any unauthorized method from executing. These programs are almost certainly the top protection from ransomware (Other than a fantastic offline backup).

The sample generates an AES essential for encrypting the file, the contents in the encrypted file are M2, as well as the AES important is encrypted Using the sub-community crucial "00000000.pky". The contents from the encrypted file are M1. Then merge M1 and M2 and include file header "WANACRY!" to save the encrypted file.
