Spartacus ransomware removal instructions

What is Spartacus?

Spartacus is a ransomware-type virus recently discovered by malware security researcher, Bart. This malware is designed to encrypt most stored files and append filenames with the ".[].Spartacus" extension (e.g., "sample.jpg" is renamed to "sample.jpg.[].Spartacus"). Once files are encrypted, using them becomes impossible. Spartacus is also designed to delete Shadow Volume Copies. After these actions, Spartacus opens a pop-up window and creates a text file ("READ ME.txt"), placing a copy in every existing folder. Updated variants of this ransomware use ".SF" extension for encrypted files.

The pop-up window and new text file contain similar messages informing victims of the encryption. To restore data, users must contact developers via an email address provided. They are encouraged to pay a ransom, after which they receive further decryption instructions. It is currently unknown whether Spartacus uses symmetric or asymmetric cryptography. In any case, Spartacus appears to employ a hard-coded string similar to a private RSA key (this algorithm generates two keys - public [encryption] and private [decryption]). Regardless of the encryption algorithm used (AES, RSA, or others), decryption requires a unique key that is evidently generated individually for each victim. In fact, since Spartacus has a hard-coded key, the situation is rather confusing - it might be a decryption key or merely an attempt to trick malware security researchers. The idea of viruses such as Spartacus is to extort victims - criminals hide keys on remote servers and encourage users to purchase them. Spartacus's ransom-demand states that the cost depends on how soon the victim makes contact with these people. In addition, users are able to attach five selected files (up to 10MB in total), which are supposedly restored and returned as a 'guarantee' that decryption is possible. Be aware, however, that cyber criminals can never be trusted. Research shows that these people often ignore victims, once payments are submitted. Paying typically gives no positive result and users are scammed. We strongly advise you to ignore all requests to contact these people or pay any ransom. This rule applies to all ransomware-type infections. As mentioned above, Spartacus contains a type of hard-coded key. Therefore, although there are currently no tools capable of restoring files encrypted by this malware, the situation might change. For now, however, your compromised data can only be restored from a backup.

Spartacus shares many similarities with RSA2048Pro, CYBERRESEARCHER, ScorpionLocker, My Decryptor, and dozens of other ransomware-type viruses. Although these viruses are developed by different cyber criminals, all have identical behavior - they encrypt data and make ransom demands. In most cases, size of ransom and type of used cryptography are the only major differences. Most of these viruses employ algorithms that generate unique decryption keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws (the key is hard-coded, stored locally or similar), restoring files without involvement of developers (contacting these people is not recommended) is impossible. These viruses present a strong case for maintaining regular data backups. It is, however, extremely important to store backup files on an unplugged storage device (e.g., Flash drive, external hard drive, etc.) or remote server (e.g., Cloud). If not, backups are encrypted together with regular data.

How did ransomware infect my computer?

Developers typically proliferate ransomware using third party software download sources, spam emails, fake software updaters, and trojans. Unofficial software download sources (peer-to-peer networks [eMule, torrents, and so on], freeware download websites, free file hosting websites, etc.) proliferate viruses by presenting them as legitimate programs. Users simply get tricked into downloading and installing malware by . Spam emails often contain malicious attachments (for example, JavaScript files, MS Office documents, and other) that, once opened, execute scripts designed to stealthily download and install malware. Fake updaters infect the system by either exploiting old software bugs/flaws or simply downloading and installing malware rather than updates. Trojans are the least complex. Most merely open "gates" for other high-risk viruses to infiltrate the system. Essentially, the main reasons for computer infections are users' lack of 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. Never open email attachments that seem irrelevant or have been sent from suspicious email addresses. Delete these emails immediately, without reading. Furthermore, download your desired applications from official sources only (using direct download links), rather than using third party downloaders/installers. These tools often spread rogue programs and should never be used. It is also extremely important to keep installed software up-to-date and have a legitimate anti-virus/anti-spyware suite installed and running at all times. Criminals proliferate malware via fake updaters and, therefore, apps should be updated using implemented functions or tools provided by the official developer only.

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 Spartacus 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 Spartacus 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 Spartacus 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 Spartacus, 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 Spartacus 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.
