Vulston ransomware removal instructions
What is Vulston?
The Vulston computer infection was discovered by Michael Gillespie. It is a high-risk ransomware-type program that encrypts data and blocks access to files unless a ransom is paid. Vulston changes the name of each encrypted file by adding the ".vulston" extension. For example, "1.jpg" becomes "1.jpg.vulston". It also generates a ransom message within a text file called "mensagem.txt", which can be found in every folder that contains encrypted files.
The ransom-demand message within the "mensagem.txt" text file states that all infected computer files are encrypted and cannot be decrypted (retrieved) without using a specific decryption key. The cost of the key (ransom size) is 0.18 of Bitcoin. Vulston's victims are encouraged to purchase the required sum of Bitcoins and transfer it to the Bitcoin wallet address provided. When the transaction is complete, victims are required to contact cyber criminals via the firstname.lastname@example.org email address and request decryption keys by providing the assigned ID. The developers promise to send a decryption key with instructions on how to use it. Victims are urged to contact cyber criminals within three three days, otherwise the decryption keys are automatically deleted (permanently) and users with infected computers will lose their data. Only Vulston developers have the decryption tool/key, which could potentially help the victims. Most cyber criminals use cryptography algorithms that generate unique keys. They store the keys on remote servers (controlled only by them). Therefore, decryption without the involvement of ransomware developers is impossible. Despite this, do not trust any cyber criminals, since they generally ignore victims even if their demands are met and ransoms are paid. In this way, people are scammed. Unfortunately, there are currently no free tools available to decrypt files. The best way to restore your files is to use a data backup that was previously created.

The number of ransomware-type infections is increasing daily, however, most are designed to serve the same purpose: to encrypt data and make ransom demands. Phobos, Seon, and Nostro are just some examples of other viruses similar to Vulston. Typically, the only differences are the cryptography algorithms used for encryption and the cost of decryption tools/keys. Unfortunately, most cyber criminals design their ransomware infections to be 'uncrackable' and only they can provide victims with decryption tools/keys. In some cases, these malicious programs are not fully-developed, have bugs/flaws, and thus possible to 'break', however, you are advised to create regular data backups and store them on remote servers or unplugged storage devices (otherwise backups might be encrypted with regular data).
How did ransomware infect my computer?
It is not known exactly how Vulston developers proliferate this ransomware, however, these programs are often proliferated via email (spam) campaigns, trojans (malicious programs), third party software download sources, and fake software updaters. Spam campaigns deliver malicious attachments (or web links) that, if opened, download and install malware. These attachments are usually Microsoft Office documents, PDF files, archive files (such as ZIP, RAR), executable files, and so on. Trojans are malicious programs that cause chain infections: once installed, they proliferate even more viruses. Various untrustworthy software download channels (freeware download websites and free file hosting sites) and P2P networks (such as eMule, torrents, etc.) are often used to present malicious software as legitimate. In this way, people are tricked into downloading and installing malware. Fake software updaters usually infect systems by exploiting bugs/flaws of the outdated software or by downloading and installing malware rather than the expected updates.
|Threat Type||Ransomware, Crypto Virus, Files locker|
|Symptoms||Can't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate Vulston virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Browse the web, download, install, and update software carefully. Emails that contain attachments that are sent from unknown/suspicious addresses should be ignored and not opened. Carefully analyze each email attachment (or web link) and open it only when you are sure that it is safe. Do not download or install software using third party downloaders or installers. These tools are often monetized by promoting untrustworthy/rogue applications. Download software using official, trustworthy sources and using direct links only. Update installed software properly using tools provided by official software developers, and not third party updaters. Have reputable anti-virus/anti-spyware software installed and enabled at all times - these tools can detect threats before they can do any damage. If your computer is already infected with Vulston, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
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 Vulston ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Vulston 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 Vulston 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 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 Vulston 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.
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:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
