The Blackoutware virus falls within the ransomware type of infection. Ransomware of such sort encrypts all the data on your PC (photos, text files, excel tables, audio files, videos, etc) and adds its own extension to every file, creating the !!!WARNING!!!.txt files in every folder with the encrypted files.
Blackoutware virus: what is known so far?
Blackoutware will add its extra .blo extension to the title of each encrypted file. For example, a file entitled “photo.jpg” will be changed to “photo.jpg.blo”. Likewise, the Excel sheet with the name “table.xlsx” will be altered to “table.xlsx.blo”, and so on.
In each folder containing the encrypted files, a !!!WARNING!!!.txt file will appear. It is a ransom money memo. Therein you can find information on the ways of paying the ransom and some other remarks. The ransom note most probably contains instructions on how to buy the decryption tool from the tamperers. You can obtain this decryptor after contacting [email protected] via email. That is it.

In the image below, you can see what a directory with files encrypted by the Blackoutware looks like. Each filename has the “.blo” extension appended to it.
How did my computer get infected with Blackoutware ransomware?
There are many possible ways of ransomware infiltration.
There are currently three most exploited ways for malefactors to have the Blackoutware virus working in your digital environment. These are email spam, Trojan introduction and peer-to-peer file transfer.
- If you access your mailbox and see letters that look just like notifications from utility services companies, postal agencies like FedEx, web-access providers, and whatnot, but whose addresser is strange to you, beware of opening those letters. They are most likely to have a malware item enclosed in them. So it is even more dangerous to open any attachments that come with letters like these.
- Another thing the hackers might try is a Trojan file scheme. A Trojan is a program that gets into your machine pretending to be something legal. For example, you download an installer of some program you want or an update for some software. However, what is unboxed turns out to be a harmful program that encrypts your data. Since the update file can have any title and any icon, you’d better be sure that you can trust the resource of the files you’re downloading. The best thing is to use the software companies’ official websites.
- As for the peer file transfer protocols like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded items with the anti-malware utility as soon as the downloading is done.
How to remove ransomware?
It is crucial to note that besides encrypting your data, the Blackoutware virus will probably deploy Vidar Stealer on your PC to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned spyware can derive your logins and passwords from your browser’s auto-filling cardfile.

Sometimes criminals would decrypt several of your files to prove that they do have the decryption tool. Since Blackoutware virus is a relatively new ransomware, anti-malware designers have not yet found a way to undo its work. However, the decryption instruments are constantly upgraded, so the effective countermeasure may soon be available.
Understandably, if the evildoers do the job of encoding someone’s essential data, the hopeless person will most likely fulfill their demands. However, paying to criminals gives no guarantee that you’re getting your blocked information back. It is still risky. After receiving the money, the racketeers may send a wrong decryption code to the victim. There were reports about ransomware developers just vanishing after getting the ransom without even writing back.
The optimal safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud storage or at least on an external disk. Surely, that might be insufficient. Your most important thing could be that file you were working upon when it all happened. But at least it is something. It is also advisable to scan your drives with the anti-malware utility after the OS restoration.
Blackoutware is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. Examples of those are Messec, Gyza, Gyew, and some others. The two basic differences between them and the Blackoutware are the ransom amount and the method of encryption. The rest is almost identical: documents become inaccessible, their extensions changed, ransom notes are found in each directory containing encrypted files.
Some fortunate users were able to decrypt the blocked files with the aid of the free software provided by anti-malware experts. Sometimes the racketeers mistakenly send the decoding code to the victims in the ransom readme. Such an epic fail allows the user to restore the files. But naturally, one should never rely on such a chance. Make no mistake, ransomware is a tamperers’ instrument to lay their hands on the money of their victims.
How сan I avert ransomware infiltration?
Blackoutware ransomware doesn’t have a endless power, so as any similar malware.
You can defend your computer from ransomware injection in several easy steps:
- Never open any letters from unknown mailers with unknown addresses, or with content that has likely no connection to something you are expecting (can you win in a lottery without even taking part in it?). In case the email subject is more or less something you are expecting, check all elements of the suspicious letter with caution. A hoax email will surely have mistakes.
- Never use cracked or untrusted programs. Trojan viruses are often distributed as a part of cracked software, possibly under the guise of “patch” to prevent the license check. But potentially dangerous programs are difficult to tell from reliable ones, as trojans may also have the functionality you seek. Try searching for information about this software product on the anti-malware forums, but the optimal solution is not to use such programs at all.
- And to be sure about the safety of the objects you downloaded, use GridinSoft Anti-Malware. This program will be a perfect defense for your PC.
🤔 How can I open “.blo” files?Are the “.blo” files accessible?
Unfortunately, no. You need to decipher the “.blo” files first. Then you will be able to open them.
🤔 The encrypted files are very important to me. How can I decrypt them quickly?
Hopefully, you have made a copy of those important files. In case you haven’t, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. There are other ways to beat ransomware, but they take time.
🤔 You have advised using GridinSoft Anti-Malware to get rid of the Blackoutware virus. Does it mean that all my files, currently encrypted, will be removed too?
No way! Unlike the ransomware program itself, the encrypted files do not jeopardize your system.
GridinSoft Anti-Malware will remove actual infections from your PC. The malware that has attacked your computer is probably still active and running scans periodically to arrest any new files you might create on your computer after the infection. As it has been mentioned above, the Blackoutware ransomware comes with the company. It installs backdoors and keyloggers that can steal your account credentials and provide hackers with easy access to your PC in the future.
🤔 What actions should I take if the Blackoutware virus has blocked my computer and I can’t get the activation code.
If that happened, you need to have a memory stick with a pre-installed Trojan Killer. Use Safe Mode to do the cleaning. The point is that the ransomware starts automatically as the system boots and encodes any new files created or imported into your system. To stop this process – use Safe Mode, which allows only the vital programs to run automatically. Consider reading our manual on running Windows in Safe Mode.
🤔 What could help the situation right now?
Some of the encrypted data can be found elsewhere.
- If you exchanged your important files through email, you could still download them from your online mailbox.
- You might have shared images or videos with your friends or relatives. Simply ask them to send those images back to you.
- If you have initially downloaded any of your files from the Web, you can try doing it again.
- Your messengers, social media pages, and cloud storage might have all those files too.
- Maybe you still have the needed files on your old computer, a laptop, cellphone, external storage, etc.
USEFUL TIP: You can employ file recovery programs1 to get your lost data back since ransomware encrypts the copies of your files, deleting the authentic ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but be advised: you won’t be able to do it before you eradicate the ransomware itself with an anti-malware program.
