BlackSheep is decryptable ransomware virus

BlackSheep is a file-encrypting virus that initiates a blue Windows Update screen as soon as it is activated on the system. While users are waiting patiently for the process to be completed, malware encrypts files and appends .666 file extension to each of them. Once “updates” are installed and targeted data corrupted, ransomware shows a lock-screen ransom note. The message is full of mistakes. However, it’s clear that cyber criminals ask to pay $500 in Bitcoins within 54 hours in order to decrypt files. Fortunately, there’s another way to restore files encrypted by BlackSheep ransomware. Victims can use StupidDecryptor and recover their files for free. Thus, there’s no need to follow hackers’ orders and wasting your money. After ransomware attack, you have to focus on its removal. Indeed, data recovery is the second step. While malware resides on the system, it might be capable of encrypting rescued files again. Therefore, do not hesitate and remove BlackSheep with Reimage or another strong malware removal program.

Ransom note by BlackSheep ransomware virus

Ransomware arrives on the system as obfuscated BLACKSHEEP.exe file. Once this file is executed, malware starts its malicious tasks. As you already know, first of all, BlackSheep delivers a fake Windows Update screen. Meanwhile, it encrypts various files stored on the computer, such as audio, video, image, picture, databases and other popular files. It might also modify Windows Registry in order to run automatically at system startup, and inject malicious processes in legitimate system processes. The last task of the ransomware is to deliver a ransom-demanding message and hope that victims will send the money. The lock-screen message includes not only the explanation of the situation but also has a contact form. Thus, it seems that cyber criminals are willing to help victims to redeem their files successfully. However, we have already revealed that following hackers’ orders is unnecessary because the virus is decryptable. However, before recovering data, it’s important to perform BlackSheep removal. Only then, you can be sure that your photographies, documents, and other records are protected from evil-minded people.

Ransomware distribution strategies and tips to avoid the attack

Developers of the BlackSheep might use multiple distribution and infiltration ways. However, you can learn how to prevent such cyber threats. The majority of file-encrypting viruses rely on the same strategies, such as malicious spam emails, malvertising,[1] bogus software downloads and updates, exploit kits, etc. Cyber criminals are using social engineering techniques in order to convince people to open a malicious file attached in the email. Not only they pretend to be from reputable organizations, but also attach a safely-looking file. Thus, the majority of users have no idea that regular PDF or Word file might be dangerous. Before opening unknown attachments, you have to double-check the information about the sender and look for other suspicious elements that might reveal cyber criminals, for instance, grammar mistakes, lack of credentials, etc.[2] BlackSheep hijack might also occur during the installation of bogus software or updates. Thus, you should stay away from various ads that are suggesting to install security tools to scan the computer for viruses. What is more, you have to always choose reliable sources for downloads and updates, such as, publishers’ site. Keeping all the programs and operating system updated also helps to avoid BlackSheep virus and other ransomware. Besides, you should strengthen your computer’s security with reputable antivirus or anti-malware program.

Elimination of the BlackSheep

BlackSheep removal has to be performed using powerful malware removal program. We highly recommend terminating the virus with Reimage or Malwarebytes Anti Malware. These tools are strong enough to find and delete all malware-related files and stop malicious processes on the system. Though, you should not forget to update your chosen software before scanning the system! However, virus removal might not be as simple as it may seem. It’s a complex cyber infection that might be designed to prevent users from installing security programs easily. If you cannot install or run your chosen software, you have to restart the computer to the Safe Mode with Networking. Then, you will be able to remove BlackSheep automatically.
