What is ViACrypt ransomware? And how does it work?

ViACrypt ransomware is a new crypt-ransomware that belongs to a group of menacing computer viruses that prevents you from accessing your files by enciphering the file’s contents using a military-grade algorithm. ViACrypt ransomware starts its computer system infiltration through the deployment of a dropper file called crawl.exe on the %APPDATA% folder of your computer. After that, it then makes changes to the settings of Remote Access Connection Manager or RASMAN to create a connection to the secret hacker server made by the sly cyber criminals behind ViACrypt ransomware. After it establishes the connection, it encrypts files using a sophisticated algorithm, the RSA 1024 that appends ViACrypt’s file extension, .via, to the targeted files. Once the encryption is completed, it drops a ransom note named; “Your system has been encrypted! Please read further instructions!.txt” on your computer that contains the following message:

Your system files has been encrypted and only way to recover them is by purchasing unlocking key.
Steps to gain access for files:
1) Please follow this page: xxxx://sigmalab.lv/other/crypt/payment_request.php
2) Upload your public encryption key
3) Download decryption key
4) Drag and drop key on crawl.exe
5) Wait for files to be unlocked in background”
