What is Wana Decrypt0r?

First discovered by S!Ri, Wana Decrypt0r is a new variant of a high-risk ransomware called WannaCry. Once infiltrated, Wana Decrypt0r encrypts most files and appends filenames with the ".wannacry" extension (e.g., "sample.jpg" is renamed to "sample.jpg.wannacry"). From this point, files become unusable. Following successful encryption, Wana Decrypt0r changes the desktop wallpaper and opens a pop-up window, both containing ransom-demand messages.

The messages state that the files are encrypted and can only be restored using a unique key. Unfortunately, this information is accurate. Although it is currently unknown whether Wana Decrypt0r uses symmetric or asymmetric cryptography, decryption requires a key generated uniquely for each victim. These keys are stored on a remote server controlled by cyber criminals (Wana Decrypt0r's developers). Therefore, users are forced to pay a ransom of $250 in Bitcoins in exchange for release of the keys. The ransom must be submitted within three days, otherwise the cost will double. It is also stated that after seven days, the system will be "destroyed" (and files probably deleted permanently). Despite the threats and demands, cyber criminals cannot be trusted. They are very likely to ignore victims, once payments are submitted - paying the ransom typically gives no positive result and victims are scammed. Therefore, you are advised to ignore all requests to pay any ransoms. There are currently no tools capable of decryption of files compromised by Wana Decrypt0r and the only solution is to restore everything from a backup.

There are dozens of ransomware-type viruses that share similarities with Wana Decrypt0r. The list includes (but is not limited to) Tornado, David, Twist, BlackRuby, and Payerranso. Although these viruses are developed by different cyber criminals, all have identical behavior - they encrypt data and make ransom demands. There are just two major differences: 1) size of ransom, and; 2) type of cryptography used. Research shows that, unfortunately, ransomware-type viruses are likely to use RSA, AES, or other algorithms that generate unique decryption keys. Therefore, in most cases, file decryption manually is impossible, unless the malware is not fully developed or has certain bugs/flaws (for instance, the key is stored locally, hard-coded, or similar). These viruses present a strong case for maintaining regular data backups. Be aware that your backup files must be stored on a remote server (such as Cloud) or unplugged external storage, otherwise the malware encrypts them as well.

How did ransomware infect my computer?

Cyber criminals proliferate malware in various ways. The most popular five are: 1) trojans; 2) fake software updaters; 3) P2P [peer-to-peer] networks; 4) unofficial software download sources, and; 5) spam emails. Trojans work very simply - most open "gates" for other high-risk malware to infiltrate the system. Meanwhile, fake updaters infect the system by exploiting outdated software bugs/flaws or installing malware rather than updates. P2P networks (torrents, eMule, etc.) and other third party download sources (free file hosting websites, freeware download websites, etc.) present malware as legitimate software. In this way, users are tricked into downloading and installing malware. Spam emails often contain malicious content (e.g., MS Office documents, JavaScript files, etc.) that, once opened, stealthily download and install malware. Essentially, the main reasons for computer infections are poor knowledge and careless behavior.

How to protect yourself from ransomware infections?

The key to computer safety is caution. Therefore, to prevent ransomware infections, be very cautious when browsing the Internet. Never open files received from suspicious email addresses. Delete these emails without reading. We also strongly recommend that you download your applications from official sources only, using direct download links. Third party downloaders/installers are used to proliferate rogue apps, and thus, these tools should not be used. Keep installed applications updated, however, since criminals employ fake updaters to proliferate malware, you are advised to use implemented update functionality or tools provided by the official developer. Having a legitimate anti-virus/anti-spyware suite installed on your computer is also paramount.

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Wana Decrypt0r ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Wana Decrypt0r ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Wana Decrypt0r are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by Wana Decrypt0r, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Wana Decrypt0r ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
