BitPaymer ransomware removal instructions
What is BitPaymer?
BitPaymer is a ransomware-type virus discovered by malware security researcher, S!Ri. Immediately after infiltration, BitPaymer encrypts most stored files and appends filenames with the ".locked" extension (i.e., "sample.jpg" is renamed to "sample.jpg.locked"). Updated variants of this ransomware use ".LOCK" extensions for encrypted files. Compromised data immediately becomes unusable. Furthermore, BitPaymer creates a text file for each encrypted file. For example (a text file named "sample.jpg.readme_txt" would be created for "sample.jpg").
The new text files contain identical messages informing victims of the encryption and encouraging them to contact contact BitPaymer's developers to receive decryption instructions. Note that the text files have the "[file_type].readme_txt" extension (e.g., "sample.jpg.readme_txt"). Therefore, to open them, users must rename the files (e.g. "sample.jpg.readme_txt" must be renamed to "sample.txt"). It is currently unknown whether BitPaymer uses symmetric or asymmetric cryptography - this information is not provided, however, each victim receives a unique key, which is necessary to restore their data. All keys are hidden on a remote server controlled by BitPaymer's developers. After contacting these people, users are encouraged to pay a ransom in exchange for release of their keys. The cost is also currently unknown. All details are supposedly provided via email, however, ransoms typically fluctuate between $500 and $1500, with payment required using cryptocurrencies. No matter what the cost, do not pay. Research shows that many ransomware developers ignore victims, after payments are submitted. Therefore, paying usually gives no positive result and users are scammed. Never attempt to contact these people and certainly do not pay any ransom. Unfortunately, there are no tools capable of cracking BitPaymer's encryption and restoring files free of charge. Therefore, the only solution is to restore everything from a backup.

The Internet is full of ransomware-type viruses similar to BitPaymer. The list of examples includes (but is not limited to) REBUS, LittleFinger, PAIN LOCKER, Embrace, and Dont_Worry. Although these viruses are developed by different cyber criminals, they have identical behavior - they encrypt data and make ransom demands. There are typically just two major differences: 1) cost of decryption, and; 2) type of cryptography used. Most of these viruses employ algorithms that generate unique decryption keys (e.g., RSA, AES, and similar). Therefore, decrypting data manually without involvement of developers (contacting these people is not recommended) is virtually impossible. The only possible scenarios are ransomware not being fully developed or having certain bugs/flaws (the key is hard-coded, stored locally or similar). Ransomware such as BitPaymer presents a strong case for maintaining regular data backups, however, it is very important to store them on a remote server or unplugged storage device, otherwise backups are encrypted together with regular files.

How to protect yourself from ransomware infections?
The key to computer safety is caution. Therefore, pay close attention when browsing the Internet. Think twice before opening email attachments. If files seem irrelevant or have been received from a suspicious email address, do not open/download them. These emails should be deleted without reading. Furthermore, download your programs from official sources only, using direct download links. Third party downloaders often include rogue apps, and thus should never be used. The same rule applies to software updates. Keep installed programs updated. To achieve this, however, use implemented update features or tools provided by the official developer only. It is also recommended that you have a reputable anti-virus/anti-spyware suite installed and running.
Text presented in BitPaymer ransomware text file :
Your network has been penetrated.
All files on each host in the network have been encrypted with a strong algorythm.
Backups were either encrypted or deleted or backup disks were formatted.
No free decryption software is available in the public.
DO NOT RESET OR SHUTDOWN - files may be damaged.
DO NOT RENAME the encrypted and readme files.
DO NOT MOVE the encrypted and readme files.
DO NOT DELETE readme files.
This may lead to the impossibility of recovery of the certain files.

- What is BitPaymer?
- STEP 1. BitPaymer virus removal using safe mode with networking.
- STEP 2. BitPaymer ransomware removal using System Restore.
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Windows 10 users: Click the Windows logo and select the Power icon. In the opened menu click "Restart" while holding "Shift" button on your keyboard. In the "choose an option" window click on the "Troubleshoot", next select "Advanced options". In the advanced options menu select "Startup Settings" and click on the "Restart" button. In the following window you should click the "F5" button on your keyboard. This will restart your operating system in safe mode with networking.

Log in to the account infected with the BitPaymer virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
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 BitPaymer 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 BitPaymer 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 BitPaymer 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 BitPaymer 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.
