BlackRuby ransomware removal instructions

What is BlackRuby?

BlackRuby is a ransomware-type virus first discovered by MalwareHunterTeam. Immediately after infiltration, BlackRuby encrypts most stored files and renames them using the "ENCRYPTED_[random_characters_and_digits].BlackRuby" pattern. For instance, "1.jpg" might be renamed to a filename such as "Encrypted_zIX2dFXFt9qNfifBu1mqkNVYTX79ZS48TWWU5BRm3Q.BlackRuby". Henceforth, files become unusable and indistinguishable. Following successful encryption, BlackRuby creates a text file ("how-to-decrypt-files.txt"), placing a copy in every existing folder.

BlackRuby has a number of interesting features that are uncommon to most ransomware-type viruses. Firstly, it checks the victim's IP address to detect the location. If the location is Iran, files will not be encrypted. Furthermore, BlackRuby infiltrates a XMRig tool used to exploit system resources to mine Monero cryptocurrency (you can read more about cryptocurrency-mining malware here). Therefore, system performance is significantly reduced. The new text file informs victims of the encryption and provides further instructions about how to restore files. It is stated that decryption requires a unique key - unfortunately, this information is correct. Although it is currently unknown whether BlackRuby uses symmetric or asymmetric cryptography, file decryption without a key (generated uniquely for each victim) is impossible. Criminals hide these keys on a remote server. Therefore, to receive a key and a decryption tool, victims must pay a ransom of $650 in the Bitcoin cryptocurrency. Furthermore, ransomware developers often ignore victims, after the ransoms are paid. Therefore, paying typically gives no positive result and users might be scammed. As well as losing their money, users will support cyber criminals' malicious businesses. For these reasons, never attempt to contact these people or pay any ransom. Unfortunately, there are no tools capable of file decryption compromised by BlackRuby ransomware. Therefore, your files and system can only be restored using a backup.

This malware is virtually identical to dozens of other ransomware-type viruses, including Payerranso, LOCKME, AAC, and GANDCRAB. Although these viruses are developed by different cyber criminals, they have identical behavior. All encrypt files and make ransom demands. Research shows that in most cases, ransomware-type viruses have just two major differences: 1) cost of decryption, and; 2) type of encryption algorithm used. Unfortunately, most employ algorithms (such as RSA, AES, etc.) that generate unique decryption keys. Therefore, unless the malware is not fully developed or has certain bugs/flaws (for instance, the key is hard-coded, stored locally, or similar), restoring files without involvement of developers (contacting these people is not recommended) is impossible. Ransomware-type viruses present a strong case for maintaining regular data backups. Bear in mind, however, that backup files must be stored on a remote server or unplugged external storage, otherwise they will be encrypted just as other regular files.

How did ransomware infect my computer?

Ransomware-type viruses are proliferated in various ways, however, the most popular five are: 1) spam emails; 2) P2P [peer-to-peer] networks; 3) unofficial download sources; 4) fake software update tools, and; 5) trojans. Spam emails often contain malicious attachments (e.g., JavaScript files, MS Office documents, etc.) that, once opened, download and install malware. P2P networks (eMule, torrents, etc.) and other third party download sources (freeware download websites, free file hosting websites, etc.) proliferate malware by presenting it as legitimate software. Users inadvertently download and install malware. Fake software updaters exploit outdated software bugs/flaws to infect the system. In some cases, these tools download viruses rather than software updates. Trojans are the simplest ones - they open "gates" for other viruses to infiltrate the system.

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, to prevent ransomware infections, be very careful when browsing the Internet. Never open files received from suspicious email addresses. You are strongly advised to download your applications from official sources only, using direct download links. Third party downloaders/installers often include ("bundle") rogue apps and, thus, these tools should not be used. Keep installed software updated and use a legitimate anti-virus/anti-spyware suite, however, since criminals proliferate malware via fake updaters, we advise you to use implemented update functionality or tools provided by the official developer only.

[Can not access your files?]

Congratulations, you are now part of our family #BlackRuby Ransomware. The range of this family is wider and bigger every day.
Our hosts welcome our presence because we will give them a scant souvenir from the heart of Earth.

This time, we are guest with a new souvenir called "Black Ruby". A ruby in black, different, beautiful, and brilliant, which has been bothered to extract those years and you must also endure this hard work to keep it.

Do not forget that your opportunity is limited. From these limits you can create golden situations. Be sure we will help you in this way and to know that having a black ruby does not always mean riches. You and your system are poor, poor knowledge of cybersecurity and lack of security on your system!.

1. Copy "Identification Key".
2. Send this key with two encrypted files (less than 5 MB) for trust us to email address "".
3. We decrypt your two files and send them to your email.
4. After ensuring the integrity of the files, you must pay $650 (USD) with bitcoin and send transaction code to our email, our bitcoin address is "19S7k3zHphKiYr85T25FnqdxizHcgmjoj1".
5. You get "Black Ruby Decryptor" Along with the private key of your system.
6. Everything returns to the normal and your files will be released.

[What is encryption?]

Encryption is a reversible modification of information for security reasons but providing full access to it for authorised users.
To become an authorised user and keep the modification absolutely reversible (in other words to have a possibility to decrypt your files) you should have an "Personal identification Key". But not only it. It is required also to have the special decryption software (in your case "Black Ruby 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 "Black Ruby Ransomware" software; the instructions ("how-to-decrypt-files.txt") in the folders with your encrypted files are not viruses, they will help you. After reading this text the most part of people start searching in the internet the words the "Black Ruby Ransomware" where they find a lot of ideas, recommendation and instructions, it is necessary to realise 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.

[Have you got advice?]

[*** Any attempts to get back you files with the third-party tools can be fatal for your encrypted files ***]
The most part of the tried-party software change data with the encrypted files to restore it but this cases 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 realise that any intervention of the third-party software to restore files encrypted with the Black Ruby Ransomware" software may be fatal for your files.

If you look through this text in the internet and realise that something is wrong with your files but you do not have any instructions to restore your files, please contact your antivirus support.
