Alfa Ransomware

   Этот крипто-вымогатель шифрует данные пользователей, а затем требует выкуп в 1-1,5 биткоина, чтобы вернуть файлы. К зашифрованным файлам добавляется расширение .bin. Имя файла тоже меняется на случайное, состоящее из букв, цифр и знаков: [10_random_chars].bin

Генеалогия: Cerber > Alfa

  Это вымогатель в настоящее время использует два различных имени в записке о выкупе и на платежном сайте TOR. Например, в записке с требованием выкупа, вымогатель упоминается как Alpha Ransomware, а на сайте TOR упомянут Alfa Decryptor с собственным логотипом. На основе разработанного Alfa-логотипа в итоге, я думаю, останется название Alfa Ransomware. Кроме того, название Alpha Ransomware ранее уже было занято другим криптовымогателем. 

Записки о выкупе называются:
README HOW TO DECRYPT YOUR FILES.HTML
README HOW TO DECRYPT YOUR FILES.TXT

Cannot you find the files you need?
Is the content of the files that you looked for not readable?
It is normal because the files' names, as well as the data in your files have been encrypted.
###########################################

!!! "Alpha Ransomware" has been removed from your computer.
###########################################
What is encryption?
-------------------
Encryption is a reversible modification of information for security
reasons but providing full access to it for authorized users.
To become an authorized user and keep the modification absolutely
reversible (in other words to have a possibility to decrypt your files)
you should have an individual private key.
But not only it.
It is required also to have the special decryption software
(in your case "Alpha Decryptor" software) for safe and complete
decryption of all your files and data.
############################################
Everything is clear for me but what should I do?
------------------------------------------------
The first step is reading these instructions to the end.
Your files have been encrypted with the "Alpha Ransomware" software; the
instructions ("README HOW TO DECRYPT YOUR FILES.TXT" and "README HOW TO DECRYPT YOUR FILES.HTML")
in the folders with your encrypted files are not viruses, they will 
help you.

Internet the words the "Alpha Ransomware" where they find a lot of
ideas, recommendations and instructions.
It is necessary to realize that we are the ones who closed the lock on
your files and we are the only ones who have this secret key to
open them.
!!! Any attempts to get back your files with the third-party tools can
!!! be fatal for your encrypted files.
The most part of the third-party software change data within the
encrypted file to restore it but this causes damage to the files.
Finally it will be impossible to decrypt your files.
When you make a puzzle but some items are lost, broken or not put in its
place - the puzzle items will never match, the same way the third-party
software will ruin your files completely and irreversibly.
You should realize that any intervention of the third-party software to
restore files encrypted with the "Alpha Ransomware" software may be
fatal for your files.
