WTDI ransomware / virus (Decryption Steps Included) - Virus Removal Guide

WTDI virus Removal Guide

What is WTDI ransomware virus?

WTDI ransomware virus targets Russian-speaking computer users

WTDI is a new file-encrypting virus that is written in .NET programming language and encodes files using strong cryptography. On the affected device, the virus looks for various documents, multimedia, archives, databases, disk image and other files, and appends the .wtdi file extension to each of them. Authors of the ransomware inform about this unpleasant situation by changing computer’s wallpaper. Once all files are encrypted, the ransom-demanding message shows up on the desktop. The fact that ransom note is written in the Russian language suggests that malware aims at the Russian-speaking computer users. Hackers follow traditional scenario and ask to pay the ransom in order to decrypt files locked by WTDI ransomware. They provide ICQ number for communication. However, trying to figure how much money cyber criminals want for decrypting your files is not a wise decision.[1] No one can assure that they have tools to restore your data or if they are truly willing to do it after receiving the ransom. Chances they will disappear as soon as the money shows up in their account are high. Thus, after the cyber attack, we highly recommend focusing on automatic WTDI removal with the help of reputable malware removal program, such as FortectIntego. Later you could try alternative recovery methods, and hopefully, they will work.

Ransom note by WTDI ransomware virus

This ransomware is activated from CryptoWall.exe. However, security experts doubt that it is related to original CryptoWall virus. It might be just a fake version of it. Once this file is executed, it has to complete few tasks on the affected device. First of all, it modifies Run and RunOnce Windows Registry sub-keys in order to start ransomware with system startup. Once it’s done, WTDI starts scanning the system looking for the targeted file types and encrypts them. Apart from that, it might also try to get particular information about user or computer. Thus, you malware might put your privacy at risk. Besides, your computer is also in danger. Nevertheless, it corrupted your files; ransomware might also be capable of installing additional malicious files or opening the backdoor for other malware. Therefore, all these reasons and possible threats should motivate you to remove WTDI as soon as possible. We want to point out that even if you decide to take crooks’ offer (not recommended), you will still need to perform virus removal. Paying the ransom does not delete virus from the system.

Cyber criminals use traditional ransomware distribution methods

The main distribution channels for WTDI virus are malicious email attachments, malvertising, bogus software updates, and downloads, exploit kits, etc. The most successful way to infiltrate computers is misleading emails that include an infected attachment.[2] This file is always camouflaged and presented as an important document. Bear in mind that even Word or PDF files might hide malware executable. Clicking on online ads might also lead to WTDI attack. Be aware that malware-laden ads might be placed not only on the high-risk websites but on legitimate ones as well. Therefore, installing programs or updates from pop-ups might end up with data loss. Lastly, when installing new software, it’s important to choose reliable sources and avoid unknown file-sharing sites or torrents that highly participate in malware distribution.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
