What is Gatz Ransomware
Gatz Ransomware is a disastrous virus, that uses AES encryption algorithms to encrypt users’ files. After encoding, files obtain following extensions: .gatz. The malware aims at encryption of personal data, such as documents, photos, videos, music, e-mails. Deep encoding makes those files unapproachable, and decryption instruments available today cannot help in most cases. To start automatically each time the OS starts, the cryptographer creates an entry in the Windows registry key that defines a list of programs that start when the computer is turned on or restarted. To determine which key to use for encryption, Gatz Ransomware tries to establish a network connection with its command server. The virus sends information about the infected computer to the server and receives the encryption key from it. In addition, the command server can send additional commands and modules to the virus that will be executed on the victim’s computer. If the data exchange with the command server was successful, the virus uses the received encryption key (online key). This key is unique for each infected computer. If Gatz Ransomware was unable to establish a connection with its server, a fixed key (offline key) will be used to encrypt files. Below you can observe _readme.txt file (ransom note), that virus places in affected folders:

Gatz Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
