.Zorro File Virus – How Does It Spread

For the .zorro file virus to cause an infection, the ransomware may take advantage of different software that may spam it. The main method by which ransomware viruses like the Zorro threat spread are via spammed e-mails that pretend to be something important for the user. The e-mails also contain an e-mail attachment and a deceptive message alongside them. This allows for the successful tricking of the victim to open the malicious attachment:

Thankfully, now there are online services, like ZipeZip which scan for archives to detect malware before you even open them, and users should look for this and other similar ways to check archives on-demand before opening them in order to increase protection.

Other methods in which the cyber-criminals behind the .Zorro ransomware virus may have invested to increase infection rate is to upload fake installers, fake patches and cracks on torrent websites and suspicious software sites. Once users download something online, like a game, for example and they want to “patch” it and play it for free, the patch is actually the virus and causes the infection.

Zorro Ransomware – Infection Activity

After a malicious executable by Zorro ransomware has been opened on the computer of the user, the virus begins to connect to a remote C2 server, the current location to which is currently unknown. From there, the malicious files of the Zorro virus are downloaded. They may be situated in the following Windows locations:

%User Profile%
%AppData%
%Local%
%Local%
%Roaming%
%LocalRow%
%System32%

After the malicious files have already been situated on the affected computer, the virus begins to perform several other modifications on it as well. One of them is to modify the Windows registry editor, more specifically the Run and RunOnce registry sub-keys. This results in the malware running on system startup.

Other activity of this virus may include the shutting down of system processes and security shields to ensure successful encryption.

Microsoft Office files.
Open Office documents.
Libre Office files.
Audio files.
Image files.
Files related to programs that are often used.

After the encryption process has completed, the Zorro ransomware infection begins to cause damages on the files by encrypting them. This results in making the files no longer to be openable. After the encryption process has completed, the .zorro file extension has been added and the files appear like the image below:
