What is Blocking ransomware?
Blocking ransomware is a new variant of the BTCWare ransomware family which has been active since April 2017. Blocking ransomware emerged on the first week of August 2017 and seems to have the same source code as other BTCWare variants, making it as dangerous as can be. Aside from the similarities in the source code of the malware, this ransomware also carries out typical ransomware attack; encrypts your important files using a strong encryption algorithm and marks the targeted files by modifying their file extensions.
How does this ransomware function?
Once it had successfully infiltrated your computer, it’ll start to scan your computer for files to encrypt. After that, it encrypts those files with [[email protected]].blocking extensions. The [email protected] serves as an indication to contact the crooks behind the malware. Right after the encryption, the virus drops a ransom note containing the documents Info.hta and !#_READ_ME_#!.hta. Here’s the full context of the ransom note:
“All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail [email protected] in body of your message write your ID
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.

[172 RANDOM CHARACTERS]”
As you can see, the developers of this ransomware seem serious since they do not hesitate to create a lengthy and detailed ransom note that explains how to recover the encrypted files. They then laid down the conditions of test decryption as a guarantee, promising you the recovery of your files once you pay the ransom. However, paying the ransom is not recommended, not to mention a dumb move for it does not guarantee that the crooks will hold their end of the bargain once they got the money. The best thing you can do is to look for other ways to get rid of the malware and recover your files which are thankfully provided on the last part of this article.
