Prometey ransomware removal instructions

What is Prometey?

Similar to AnteFrigus, Prometey is malicious software classified as ransomware. It operates by encrypting data and demanding payment for decryption. During the encryption process, all affected files are appended with an extension, consisting of a random character string. For example, a filename such as "1.jpg" would be similar to "1.jpg.caacbbcc". After this process is complete, a ransom message with the format "CLICK_HERE-[random_string].txt" (e.g. "CLICK_HERE-caacbbcc.txt") is dropped into every affected folder.

The ransom message within the text files informs victims that their files have been encrypted and, to recover them, contact must be established with the cyber criminals behind the infection. This is to be done via an online chat session. The message instructs users to open the provided link (using any browser). They are then to enter certain information into the website: the IDs assigned to them and personal keys (located in the message) and their email addresses. Should victims be unable to access the site, they are advised to use the Tor browser. If that is not sufficient (i.e., access still cannot be gained), they are instructed to use a VPN. The message ends with warnings that rebooting the system, using third party decryption tools/software, running an antivirus program or uninstalling Prometey malware will result in permanent data loss. Unfortunately, in most cases of ransomware infections, decryption is impossible without the involvement of the criminals responsible, unless the malicious software in question is still in development and/or has bugs/flaws. Whatever the case, you are advised not to communicate with or meet the demands of any cyber criminals. Despite paying, victims do not receive the promised decryption tools/software. Therefore, their data remains encrypted and useless, and they experience significant financial loss. To prevent Prometey from further encryption, it must be removed from the operating system, however, removal will not restore already compromised files. The only solution is to recover them from a backup, if one was made prior to the infection and was stored separately (so as not to have been affected by Prometey).

Ransomware is designed to encrypt data and demand ransoms to be paid for decryption. SDfghjklBadutClowns TeamIwanttits, and Onix are some examples of malware within this classification. These malicious programs have two key differences: the cryptographic algorithm they use (symmetric or asymmetric) and the demanded payment size. Ransoms usually range between three and four digit sums (in USD). Cyber criminals tend to prefer digital currencies (mainly, cryptocurrencies), since these transactions are difficult/impossible to trace. To protect data integrity, backups should be created and kept on remote servers and/or unplugged storage devices. It is best to store backups in several different locations.

How did ransomware infect my computer?

The most common proliferation methods of ransomware and other malware are through trojans, spam campaigns, software "cracking" (activation) tools, fake updaters and untrusted download sources. Trojans are malicious programs designed to cause chain infections (i.e., download/install additional malware). Spam campaigns are used to send thousands of deceptive/scam emails with infectious files attached (or they contain links leading to them). These messages are typically disguised as "official", "important", "urgent" or similar. The dangerous files come in various formats: archive (RAR, ZIP) and executable (.exe, .run) files, PDF and Microsoft Office documents, JavaScript, etc. When executed, run or otherwise opened, the infection starts. Rather than activating licensed software, illegal activation tools ("cracks") can download/install malware. Rogue updaters infect systems by exploiting flaws of outdated programs or simply installing malware rather than the promised updates. Untrustworthy download channels such as unofficial and free file-hosting sites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders can offer malicious software for downloading.

How to protect yourself from ransomware infections

Do not open suspect or irrelevant emails, especially files or links present in this type of mail, as this can result in an infection. Use official and verified download sources. The same extends to program activation and updating, which should be done with tools/functions provided by genuine developers. Illegal activation ("cracking") tools and third party updaters can download/install malware, and should not be used. To ensure device integrity and user safety, it is important to have a reputable anti-virus/anti-spyware suite installed. This software must be kept up to date, used to run regular system scans and for the removal of detected threats/issues. If your computer is already infected with Prometey, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

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 Prometey 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 Prometey 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 Prometey 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 Prometey, 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 Prometey 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.

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