What is Btcware Ransomware
Btcware is a popular ransomware family counting a number of versions since 2017. The ransomware developed by this group of cybercriminals has evolved into using stronger and more secure algorithms. Since there are many versions of Btcware, the world has seen many types of encryption throughout its span of existence. For example, older versions used to apply old RC4 algorithms, until the rise of AES-192 and AES-256 in later samples. The same story goes with extensions. Each version of Btcware involves a brand new extension different from others. The names of original data infected by Btcware usually face the change and accompanied by a random 5-character extension. Here are the possible templates used by Btcware:
.id_.., or simply
.. To illustrate, a file like
1.mp4 would change to
1.mp4.[firstname.lastname@example.org].gryphon or similarly. There are lots of extensions corresponding to different variants of Btcware – .btcware, .gryphon, .aleta, .crypton, .nuclear, .wyvern, .payday, .cryptowin, .cryptobyte, .theva, .xfile, .onyon, .blocking, .master, and countless more. Traditionally, once the encryption is done, ransomware programs create a text note file containing instructions to recover your data. The name of a note also depends on which version pounced your system, but usually, it is #_HOW_TO_FIX_!.hta or READ ME.txt.

Inside of this note, cybercriminals use clumsy introductions ostensibly meant to explain what happened. Then, they ask to contact them via attached e-mails to get in further touch. Once done, users will receive a set of instructions to buy the decryption software. Some versions of Btcware require 0.5 BTC for data encryption. If you do not have this money to pay, there is a chance that extortionists will threaten you with permanent loss or inappropriate data abuse. In most cases, files encrypted with AES algorithms are hard to decrypt unless you purchase the private key held by cybercriminals themselves. Paying a ransom is not a good solution either, since there is a chance of being money-dumbed. The great news is that some versions of Btcware are decryptable with the help of third-party software. The most recent ones are probably not, however, you can delete Btcware, save your files, and wait until the new decryption kicks in. Otherwise, your only and risky solution remains to spend money on paying the ransom.

How to protect computer from viruses, like Btcware Ransomware, in future
1. Get special anti-ransomware software
Use ZoneAlarm Anti-Ransomware
Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.
2. Back up your files
As an additional way to save your files, we recommend online backup. Local storages, such as hard drives, SSDs, flash drives, or remote network storages can be instantly infected by the virus once plugged in or connected to. Btcware Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
