The Black Berserk belongs to the ransomware type of infection. Malware of this type encrypts all user’s data on the PC (photos, text files, excel tables, audio files, videos, etc) and adds its specific extension to every file, creating the Black_Recover.txt text files in each folder containing encrypted files.
Black Berserk Virus
Black berserk appends its own .Black extension to every file’s name. For example, an image entitled “photo.jpg” will be altered to “photo.jpg.Black”. In the same manner, the Excel table named “table.xlsx” will end up as “table.xlsx.Black”, and so on.
In each folder with the encoded files, a Black_Recover.txt text document will be created. It is a ransom money memo. It contains information on the ways of paying the ransom and some other information. The ransom note most probably contains a description of how to purchase the decryption tool from the tamperers. You can obtain this decryptor after contacting [email protected], [email protected] via email. That is it.

Your ID : - # In subject line please write your personal ID Contact us: [email protected] [email protected] ATTENTION! All files have been stolen and encrypted by us and now have Black suffix. # What about guarantees? To prove that we can decrypt your files, send us two unimportant encrypted files.(up to 1 MB) and we will decrypt them for free. +Do not delete or modify encrypted files. +Decryption of your files with the help of third parties may cause increased price(they add their fee to our).
In the image below, you can see what a directory with files encrypted by the Black berserk looks like. Each filename has the “.Black” extension added to it.
How did Black berserk ransomware end up on my PC?
There is a huge number of possible ways of ransomware injection.
Nowadays, there are three most popular ways for malefactors to have the Black berserk virus acting in your digital environment. These are email spam, Trojan infiltration and peer networks.
If you open your mailbox and see emails that look just like notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose addresser is unknown to you, be wary of opening those letters. They are very likely to have a malware item enclosed in them. Thus it is even riskier to open any attachments that come with letters like these.
Another option for ransom hunters is a Trojan horse scheme. A Trojan is a program that infiltrates into your computer pretending to be something different. For instance, you download an installer for some program you want or an update for some program. But what is unpacked turns out to be a harmful program that encrypts your data. As the update wizard can have any name and any icon, you have to make sure that you can trust the resource of the things you’re downloading. The optimal way is to trust the software companies’ official websites.
As for the peer-to-peer networks like torrents or eMule, the threat is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. So you’d better be using trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded items with the antivirus as soon as the downloading is finished.
How to remove ransomware?
It is important to inform you that besides encrypting your files, the Black berserk virus will probably deploy Vidar Stealer on your computer to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned program can derive your credentials from your browser’s auto-filling data.
How to avoid ransomware injection?
Black berserk ransomware has no superpower, neither does any similar malware.
You can armour yourself from ransomware injection taking several easy steps:
- Never open any emails from unknown mailers with unknown addresses, or with content that has likely no connection to something you are waiting for (can you win in a money prize draw without even taking part in it?). In case the email subject is more or less something you are expecting, check all elements of the questionable letter with caution. A hoax email will always have mistakes.
- Avoid using cracked or unknown software. Trojans are often distributed as an element of cracked software, most likely as a “patch” preventing the license check. But dubious programs are difficult to distinguish from trustworthy software, as trojans sometimes have the functionality you need. Try searching for information about this software product on the anti-malware message boards, but the optimal way is not to use such software.
Frequently Asked Questions
🤔 How can I open “.Black” files?Can I somehow access “.Black” files?
Unfortunately, no. You need to decipher the “.Black” files first. Then you will be able to open them.
🤔 The encrypted files are very important to me. How can I decrypt them quickly?
It’s good if you have fаr-sightedly saved copies of these important files elsewhere. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. There are other ways to beat ransomware, but they take time.
🤔 What should I do if the Black berserk ransomware has blocked my computer and I can’t get the activation key.
🤔 What could help the situation right now?
Some of the blocked files can be found elsewhere.
- If you sent or received your important files via email, you could still download them from your online mail server.
- You might have shared images or videos with your friends or relatives. Simply ask them to give those pictures back to you.
- If you have initially got any of your files from the Web, you can try downloading them again.
- Your messengers, social media pages, and cloud disks might have all those files as well.
- It might be that you still have the needed files on your old PC, a notebook, phone, flash memory, etc.
HINT: You can use data recovery utilities1 to retrieve your lost information since ransomware arrests the copies of your files, removing the original ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but remember: you can do it only after you eradicate the ransomware itself with an anti-malware program.
