Uninstall [email protected] Ransomware & Retrieve ‘.master’ Extension Files

[email protected] Ransomware: How Breakneck is It?

 

Unfortunately, [email protected] Ransomware is not a joke like few ransomware projects that we have come across before. Apparently, the ransomware is a variant of BTCWare ransomware and it was first spotted in the first week of June 2017. Primarily, it is being distributed among Windows users. Please noter that it can only infect computers running on 64-bit architecture. However, you should not be careless if you have got 32-bit system because its single update can make it capable of targeting 32-bits systems. It will be best, if you keep a reliable security software installed and up-to-date to latest virus definition database.

Furthermore, cyber security experts revealed that Microsoft Word documents are customized by threat actors that include a special macro-enabled document usually deliver [email protected] Ransomware onto your computer. Following infiltration, the ransomware launches an AES encryption engine that indexes certain types of files saved onto your computer and then starts encrypting them using a custom cipher. Next, you find encrypted files onto your local disk featuring '.master' or '.blocking' or '.xfile' or '.cryptobyte' or '.btcware' or '.theva' extension. You should know that files having any of these extensions will be totally inaccessible and useless. Until you don't recover them, you can open them using any of your Windows applications.
