BlackRuby Ransomware Removal Instruction

BlackRuby-Threat In Detail

BlackRuby Ransomware is the first Ransomware threat that integrates cryptocurrency mining component. This means that along with encrypting files on the attacked computer system, the threat will also employ the system’s CPU resources to mine for crypto-mining.

The Ransomware threat uses the common way of intrusion like other Ransomware which is spam mails embedded with macro-enabled document which once run will drop the payloads of the threat and install it without user’s consent. Using the same distribution method example are:‘.justice File Extension’, Xorist-Frozen Ransomware, LockMe Ransomware, and many others.

Once installed successfully, BlackRuby Ransomware uses AES-256 and RSA-2048 enciphers to encode the files like documents, images, music, videos, databases, spreadsheets, eBooks, PDFs and presentations. The encrypted files are given the white icon and the ‘Encrypted_%[random characters]%’ extension. After encryption been done, it deletes the Shadow volume copies created by Windows to make users unable to recover their files from other means.

Meanwhile, BlackRuby ransom threat drops the updated version of “XMRig” and connects to the “h[tt]ps://www.monero[.]how” URL to mine for Monero coins. However, researchers claim that the ransomware deletes its files after data is been encrypted and presents the ransom note for the victims to know about the encryption. The XMRig tool keeps running within the attacked system to continue the mining process and earn huge profit. XMRig is installed within the AppData directory.

The ransom note is a text file named as ‘how-to-decrypt-files.txt’ that instructs user to buy ‘Black Ruby Decryptor’ by paying 650 USD worth of Bitcoin in the given address of the Bitcoin wallet. The victims may communicate with the authors with the provided email address ‘’.

The ransom note by BlackRuby Ransomware reads as:
