VIVELAG ransomware removal instructions

What is VIVELAG?

VIVELAG is a malicious program, belonging to the Sapphire ransomware family. Its discovery is credited to dnwls0719. It is designed to encrypt data and demand payment for the decryption. During the encryption process, all affected files are appended with the ".VIVELAG" extension. For example, a file titled something like "1.jpg" would appear as "1.jpg.VIVELAG" - following encryption. After this process is complete, a pop-up window is displayed - containing a ransom note in French. The VIVELAG ransomware is decryptable, the decryption key is "052250058205075025075207820" (without the quotation marks). However, should this malware be updated - this key may no longer be able to recover the compromised files.

According to a rough translation, the ransom-demanding message within the pop-up window, informs victims that their data has been encrypted. It is clarified that the files have not been deleted, they were encrypted - hence, rendered unreadable. To decrypt the data, users are instructed to purchase the decryption key from cyber criminals behind the infection. The price (ransom) is stated to be 250$ (presumably, US dollars) in Bitcoin cryptocurrency. Should victims fail to pay, restart/reboot the system, remove the malicious program and/or run anti-virus software - they risk losing their data permanently. The pop-up contains a field into which the decryption key must be entered. Fortunately, VIVELAG has been decrypted; 052250058205075025075207820 - is the decryption key. This is not particularly common in ransomware infections, as the decryption keys and tools tend to be unique (i.e. generated individually for each victim). In seldom cases when the malicious programs are still in development and/or have significant bugs (flaws) - manual decryption (i.e. without involvement of the criminals responsible) might be possible. Whatever the case, it is expressly advised against meeting the ransom demands. Since often, despite paying - victims do not receive the promised decryption keys/tools. Therefore, they experience financial loss and their data remain encrypted and worthless. Removing the ransomware from the operating system will prevent it from further encryptions. However, removal will not restore already affected files. In such cases, the only solution is recovering the data from a backup. If one was created prior to the infection and was stored in a separate location.

Space!Shadow and Hex911 are a few examples of other ransomware-type programs. They are designed to encrypt data and demand ransoms for the decryption tools. There are two main differences in-between: the cryptographic algorithms they use (symmetric or asymmetric) and the ransom size. The latter typically range from three to four digit sums (in USD). Digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.) are commonly used for the payments, due to them being difficult/impossible to trace. To avoid data loss, it is strongly recommended to keep backups in unplugged storage devices and/or remote servers (ideally, in multiple different locations).

How did ransomware infect my computer?

Ransomware and other malware are primarily distributed via trojans, spam campaigns, illegal activation ("cracking") tools, fake updaters and dubious download channels. Trojans are malicious programs, some types of which can cause chain infections (i.e. download/install additional malware). The term "spam campaign" defines a large scale operation, during which deceptive emails are sent by the thousand. This scam mail contains infectious files, as attachments and/or download links. Virulent files can be in various formats (e.g. archives, executables, Microsoft Office and PDF documents, JavaScript, etc.) and when they are executed, run or otherwise opened - it triggers the infection process. Rather than activate the licensed product, illegal activation tools ("cracks") can download/install malicious software. Illegitimate updaters cause infections by exploiting flaws of outdated products and/or by simply installing malware instead of the promised updates. Malicious content can be unintentionally downloaded from untrustworthy sources, e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders.

How to protect yourself from ransomware infections?

It is recommended not to open suspicious and/or irrelevant emails, especially any attachments or links present in them - due to high-risk of serious system infections. All downloads must be done from official and verified sources. It is just as important to activate and update programs with tools/functions provided by legitimate developers. Using illegal activation ("cracking") tools and third party updaters is ill-advised, as they are often employed to proliferate malware. To protect device and user safety, it is paramount to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date. Furthermore, this software must be used to run regular system scans and to remove detected/potential threats. If your computer is already infected with VIVELAG, we recommend running a scan with Malwarebytes 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 VIVELAG 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 VIVELAG 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 VIVELAG 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 VIVELAG, 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 VIVELAG 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, and 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.
