- Analyzing If it has infected your computer system previously and if so deletes itself.
- Establish a connection with the cyber-criminals running it.
- Creating Windows registry entries in the “Run” or “RunOnce” Registry sub-keys.

The files targeted for encryption are the following:
- Anything conserved in a USB or other drive.
These files are encoded by using Advanced Encryption Standard, also known as AES. This is a very tough cipher to crack and it changes blocks of data from the original file, to make it no longer functioning. The result of this encryption is that a unique decryptor key is generated that can reverse the process and make your files usable again.
