OBLIVION ransomware removal instructions

What is OBLIVION?

OBLIVION is a ransomware-type virus recently discovered by malware security researcher, Michael Gillespie. Once infiltrated, OBLIVION encrypts most stored files. In addition, it renames them using the "[gibberish].OBLIVION" pattern. For example, "sample.jpg" might be renamed to a filename such as "88ea2M65a2==ixH6t4Ht789fvC49W.OBLIVION". Encrypted files become unusable and indistinguishable. Immediately after encryption, OBLIVION generates a text file ("OBLIVION DECRYPTION INFORMATION.TXT") and places a copy in every existing folder. Note also that there is a high probability that OBLIVION is related to another ransomware infection called Scarab.

As usual, the new text file informs victims of the encryption and states that, to restore data, victims must purchase a decryption tool for a certain amount of Bitcoins. To achieve this, users must first contact cyber criminals. In addition, they are able to attach a single selected file, which is then restored and returned (together with payment instructions) as a 'guarantee' that decryption is possible. It is currently unknown whether OBLIVION  uses symmetric or asymmetric cryptography - this information is not provided, however, it is clear that decryption requires a unique key generated individually for each victim. Cyber criminals store these keys on a remote server, thus allowing them to blackmail victims. To receive the key (or rather, a decryption tool with the key embedded within), users must submit payment. The cost is also not specified - users will receive detailed instructions via an email, however, costs typically fluctuate between $500 and $1500. Note that cyber criminals can never be trusted. These people are likely to ignore victims, once payments are submitted. Therefore, no matter what the cost, do not pay. There are currently no tools capable of restoring data encrypted by OBLIVION free of charge. There is just one solution: to restore everything from a backup.

There are dozens of ransomware-type viruses that share similarities with OBLIVION. The list of examples includes (but is not limited to) PAY_IN_MAXIM_24_HOURS, Kraken 2.0, Black Heart, MaxiCrypt, and Spartacus. All are developed by different cyber criminals, and yet their behavior is identical - all encrypt data and make ransom demands. In most cases, ransomware-type viruses have just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most use algorithms (e.g., RSA, AES, etc.) that generate unique decryption keys. Therefore, unless the malware has certain bugs/flaws (e.g., the key is hard-coded, stored locally, etc.), restoring files manually without involvement of developers (contacting these people is not recommended) is impossible. Ransomware presents a strong case for maintaining regular data backups, however, note that backup files must be stored on a remote server or unplugged storage device. If not, they will be encrypted together regular data.

How did ransomware infect my computer?

Ransomware-type viruses are distributed in various ways. The most popular five are: 1) trojans; 2) fake software update tools; 3) peer-to-peer [P2P] networks; 4) unofficial download sources, and; 5) spam emails. Most trojans work simply - they merely open "gates" for other high-risk viruses to infiltrate the system. Fake updaters infect the system by exploiting outdated software bugs/flaws or simply downloading and installing viruses rather than updates. P2P networks (i.e., torrents, eMule, etc.) and other third party download sources (free file hosting websites, freeware download sites, and so on) proliferate viruses by presenting them as legitimate software. Users are often tricked into downloading and installing malware. Spam emails are delivered with various infected attachments (e.g., MS Office documents, JavaScript files, etc.) that, once opened, run scripts designed to 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, pay close attention when browsing the Internet. Before opening email attachments, be sure that files seem relevant and have been sent from trustworthy/recognizable email addresses. If not, do not open these files and delete the emails immediately. Furthermore, you are advised to download your apps from official sources, using direct download links, rather than third party downloaders/installers. These tools often promote deceptive applications, and thus should never be used. Keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite, however, since criminals proliferate malware using fake updaters, update applications using implemented functions or tools provided by the official developer only.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

3. Next, type this line: rstrui.exe and press ENTER.

system restore using command prompt rstrui.exe

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 OBLIVION 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 OBLIVION 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 OBLIVION 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 files encrypted by OBLIVION, 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 OBLIVION 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.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
