.tornado File Virus – Distribution

How the .tornado file virus may invade your system is via email spam messages, links to compromised web pages, freeware installers, fake software update notifications and other shady techniques of distribution.

Hackers mostly prefer the spam emails as senders’ names and subject lines are easily spoofed. The emails that deliver ransomware infections usually pose as reliable websites, services, or institutions.
Common traits of emails carriers of malware are:

• Spoofed email address and sender
• Text messages that attempt to provoke sense of urgency
• File attachment you need to download and see as soon as possible

The threat has been proved to be a new iteration of the InsaneCrypt ransomware. Happily, the security researcher Michael Gillespie released an effective decryptor for the .tornado files. We have included it in the instructions below so you can utilize it after the removal process.

.tornado File Virus – Data Encryption

Being a data locker ransomware .tornado primarily aims to scan the system for predefined types of files in order to encrypt them. Security researchers who have been analyzing the threat’s samples stated that .tornado is supposed to utilize the RSA cipher to encode target data.

After encryption, all corrupted files can be recognized by the two specific file extensions appended at the end of their names. The string follows the pattern:

→.[email].Tornado

Files that store important information like documents, text files, databases, projects, audio records, images and photos may be encrypted in case .tornado file virus infection.

Unfortunately, the ransomware leaves all encrypted files completely out of order. Your access to all .tornado files is restricted until you pay the ransom or utilize alternative data recovery approach. Some of these approaches are listed in our guide below.

Тo reduce the data recovery options with one, the crypto virus currently known as Tornado, opens the Command Prompt panel to write the following command there:

→vssadmin.exe Delete Shadows /All /Quiet

Thereby, the ransomware deletes all Shadow Volume copies stored by the Windows system.
