It is also known as BTCLocker ransomware and hails from the same family as an old Radamant ransomware. However, there are a lof other associations since the name matches with the one used by Dharma ransomware is known for having various similar versions with BTC in the file extension. In this case, cryptovirus appends .id-[victim's_ID].[btc@fros.cc].btc file extension. After getting on the computer, each of these ransomware viruses starts encrypting[1] files and makes them useless, then marks each encoded file by appending .BTC file extension.

The creators of BTC ransomware virus provide three different emails for communication: btc@fros.cc, 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.

Instead of thinking about this data recovery option, remove BTC ransomware from the computer.

The creators of BTC ransomware have been demanding from 0.5 to 1.5 Bitcoins[2] from their victims in exchange for their decryption tool. They will do their best to scare you once you contact them. For example, you can be informed on the ransom note, in particular, 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.

Some ransomware viruses are capable of deleting corrupted files; that’s why it’s crucial to get rid of any malware as soon as it announces about its appearance.

Malware spreading techniques include spam emails
Ransomware is not distributed using some unique proliferation techniques. Mostly, it has been delivered via malicious emails.[4] It means that you should be extremely careful when opening emails, especially when dealing with emails 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 cybercriminals 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[5] and signatures to the message to make it look credible.
They can also create long stories why should the victim open the message and look 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.
