How dangerous is BTC ransomware?

BTC ransomware virus was spotted in the end of 2016. It is also known as BTCLocker ransomware and hails from the same family as an old Radamant ransomware. Unfortunately, it is known that this file-encrypting virus is still actively spreading on the Internet. We believe that the name of the virus is an abbreviation of the word “Bitcoin”[1] – a virtual payment network that this virus asks its victims to use to pay the ransom. After getting inside the computer, the virus starts encrypting files and makes them useless by appending .BTC file extension to each corrupted file. As soon as it finishes this job, it delivers a ransom note called BTC_DECRYPT_FILES.txt or IDR__BTC_DECRYPT_FILES.txt where cyber criminals shortly inform that victims have to contact them as soon as possible. This feature resembles XTBL viruses[2][3][4] which ask victims to contact hackers via email. The creators of BTCLocker virus provide three different emails for communication: zikr@protonmail.com, zikra@protonmail.com, and zikr@usa.com. However, you should not consider writing and sending an email to them. They have prepared many blackmailing and psychological terror techniques to encourage victims to make the payment. Unfortunately, there’s no guarantee that they will provide necessary software for file decryption or it will work properly. Instead of thinking about this data recovery option, remove BTC ransomware from the computer. Then you will be able to recover your files from backups or using additional data recovery options presented at the end of the article.

The creators of BTC virus have been demanding from 0.5 to 1.5 Bitcoins from their victims in exchange for their decryption tool. Believe us, they will do their best to scare you once you contact them. For example, you can be informed that a decryption key is the only way to recover your data. Then, you can learn that you will receive the key right after making a payment to them. However, you can hear nothing after paying because you are dealing with hackers. To make the situation even more dramatic, the authors of BTCLocker ransomware might frighten you into paying even more money to give you a chance to restore all encrypted data, not just several files, on your computer.[5] Some ransomware viruses are capable of deleting corrupted files; that’s why it’s crucial to remove BTCLocker or any other ransomware virus as soon as it announces about its appearance. This will not recover encrypted files, but protect your PC from other problems and infections. Therefore, we recommend initiating BTC virus removal immediately with the help of professional malware removal tools. We recommend Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus.

How does malware spread?

BTCLocker virus is not distributed using some unique proliferation techniques. Mostly, it has been delivered via malicious emails.[6] It means that you should be extremely careful when opening emails, especially when dealing with mails from unknown people. Please, do not trust those messages claiming that you need to verify the invoice or similar document and stay away from the files attached to them. Keep in mind that cyber criminals have been using various techniques to make these messages appear trustworthy and related to well-known companies. They can not only insert legitimate-looking logos and signatures to the message to make it look credible. They can also create long stories why should the victim open the message and loot at the contents of the attached file. If the user falls for such trickery and opens a malicious attachment, ransomware can easily enter the system and encrypt valuable files.To sum up, you need to be extremely careful with what you click on and think twice before opening email letters that come from people or organizations that you have no business with!

Bonus: Recover your data

Guide which is presented above is supposed to help you remove BTC from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

In most cases, ransomware attack means permanent loss of personal data. Unless you have a data backup, it is impossible to recover data. It is also not possible to brute-force the decryption password, because it is a long and complex set of symbols, and even the most powerful computers would have to try for years to find out what is the real decryption key. However, there are some data recovery methods that you should try – they might help you to restore at least some of your files encrypted by BTC ransomware.

If your files are encrypted by BTC, you can use several methods to restore them:

Restore files encrypted by ransomware with Data Recovery Pro

Data Recovery Pro is a reliable software that can restore encrypted, corrupted, or deleted files. Use it as explained below.

Use Windows Previous Versions feature to recover your blocked files

You can use Windows Previous Versions feature to restore the most important files individually. Keep in mind that you can use this method only if System Restore function has been enabled before BTCLocker virus attack. This is how you should do it: 

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Use Radamant decrypter to recover files encrypted by BTCLocker

If you are desperate to recover your encrypted files, you can try using Radamant decrypter. However, we cannot guarantee that this tool will work for you because it is designed for another ransomware virus.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from BTC and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
