What is RaRansomware?

RaRansomware is a ransomware-type virus discovered by malware security researcher, Karsten Hahn. Once infiltrated, RaRansomware encrypts most stored files using AES-128 and RSA-1028 encryption algorithms. During encryption, RaRansomware renames each file using the "[16_random_characters].EGENH" pattern. For instance, "sample.jpg" might be renamed to a filename such as "NGBaAGoAcCBnAA==.EGENH". Following successful encryption, RaRansomware generates an HTML file ("RaRansomware - Recovery instructions.html") and places a copy in each existing folder.

As usual, the new HTML file contains a message stating that data is encrypted and that a ransom must be paid if victims want to restore their files. As mentioned above, RaRansomware uses AES and RSA cryptographies. Therefore, two unique keys (generated individually for each victim) are necessary to restore data. Cyber criminals hide all keys on a remote server and victims must pay ransoms for their release. The cost is not specified - users are encouraged to visit RaRansomware's website and follow the instructions. Note that cyber criminals typically demand $500-1500 in Bitcoins or other cryptocurrencies. No matter what the cost, do not pay. Research shows that cyber criminals often ignore victims, once payments are submitted. Paying typically gives no positive result and users are scammed. Therefore, you are strongly advised to ignore all requests to submit payments. Unfortunately, there are no tools capable of cracking RaRansomware encryption and restoring data free of charge. There is only one solution: to restore everything from a backup.

RaRansomware is virtually identical to many ransomware-type viruses such as KyMERA, ANIMUS, KRAB, and Aurora. Research shows that although these viruses are developed by different cyber criminals, their behavior is identical - all encrypt data and make ransom demands. In most cases, these viruses have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most employ algorithms that generate unique decryption keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws (e.g., the key is stored locally, is hard-coded or similar), restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. Malware such as RaRansomware presents a strong case for maintaining regular data backups, however, store backup files on a remote server (e.g., Cloud) or an unplugged storage device (external hard drive, Flash drive, etc.) This will prevent ransomware from encrypting backups together with regular files.

How did ransomware infect my computer?

To proliferate ransomware, developers typically use spam emails, P2P (peer-to-peer) networks, third party software download sources, fake software updates, and trojans. Spam emails are delivered with malicious attachments (e.g., MS Office documents, JavaScript files, etc.) that, once opened, execute scripts designed to download and install malware. P2P networks (torrents, eMule, etc.) and other unofficial download sources (freeware download websites, free file hosting sites, etc.) present malware as a legitimate software. Therefore, many users are tricked into downloading and installing malware. Fake software updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. Trojans simply open "backdoors" for other viruses (in this case, malware) to infiltrate the system. Ultimately, 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, pay close attention when browsing the Internet and downloading/updating/installing software. Carefully analyze each email attachment. If received files seem irrelevant or have been received from a suspicious email address, they should never be opened. Furthermore, you are strongly advised to avoid using third party download/installation tools, since they often include rogue apps. Apps should be downloaded from official sources only, using direct download links. The same applies to software updating. Keep installed programs up-to-date, but use implemented functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount. If your computer is already infected with RaRansomware, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".

restore system files and settings

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 RaRansomware 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 RaRansomware 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 RaRansomware 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.

Restoring files encrypted by CryptoDefense

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 RaRansomware, 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 RaRansomware 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.
