Prometheus Ransomware
Prometheus ransomware is a cryptovirus that acts like a typical data locker. Its purpose is to reach and encode personal files. Then it extorts a ransom fee from victims. It has been spotted in active attack campaigns. Prometheus ransomware locks files with the AES cipher algorithm which prevents their normal usage. Hackers who stand behind Prometheus virus attacks possess a decryption tool that could possibly restore locked files. Still, all victims should know that a ransom payment does not guarantee a reliable solution for corrupted files. This action may lead to data and money loss.
In the unfortunate event that you are a victim of Prometheus ransomware, it is recommendable to avoid any negotiations with cybercriminals and consider the help of secure weapons of choice. Keep reading.

Update August 3, 2021
CyCraft, a Taiwanese security company, has recently released a free decryption tool that can help victims of the Prometheus ransomware decrypt some of their files. According to TheRecord and EmsiSoft, the only downside of CyCraft’s decryptor is that it can only handle brute-forcing the decryption key from small files only.
Prometheus decryptor was released on July 13, which is also the last date when the ransomware gang published anything on its dark web site. The gang has ceased operations since then.
The Prometheus decryptor is available on GitHub.
Prometheus Virus
Prometheus ransomware is a threat that causes serious system security issues. Its impact could be eliminated after a complete removal process of malicious files from the infected system.
Currently, Prometheus ransomware is attacking online users worldwide. Popular techniques like malspam, freeware installers, and corrupted websites may be utilized for the spread of its infection files.
Malspam is a technique that is believed to be preferred by hackers. It helps them to spread the threat via massive spam email campaigns. Email messages that are part of such campaigns usually attempt to trick people to download malicious files on their PCs without suspecting that they will infect the machines with ransomware. The ransomware may be presented as an important document (file attachment), a clickable link/button, or another element.
Once this threat is started on a target operating system, it damages system settings and sets its harmful files to load automatically on every system start. All malicious processes including the data encryption happen in the background of all other running processes. Hence, they remain hidden. An issue that could be noticed during the attack is slow system performance.
For the encryption of personal files, the Prometheus virus uses the strong cipher algorithm – AES. Since this algorithm is almost unbreakable, the most effective solution for decrypting locked files is a specific tool possessed by hackers. Their decryption tool should be used with a specific key which Prometheus generates during the encoding process.
That’s why they attempt to blackmail victims into paying a solid ransom fee in exchange for the key and the decryption tool. Since they should stay anonymous, they often require ransoms to be paid in Bitcoin or another cryptocurrency. The extortion is realized with the help of two ransom messages – RESTORE_FILES_INFO.txt and RESTORE_FILES_INFO.hta. One of the messages states:
YOUR COMPANY NETWORK HAS BEEN HACKED
All your important files have been encrypted!
Your files are safe! Only modified.(AES)

Step 2: Uninstall Prometheus and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Prometheus on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Prometheus there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Prometheus
