The Blackdream virus belongs with the ransomware type of infection. A harmful program of such sort encrypts all user’s data on the PC (photos, text files, excel tables, audio files, videos, etc) and appends its extra extension to every file, leaving the ReadME-Decrypt.txt text files in every folder containing encrypted files.
Blackdream virus: what is known so far?
The pattern of renaming is this: [idxxxxx].[contact-email].BlackDream. As a part of encryption, a file entitled, for instance, “report.docx” will be turned into “report.docx.[9ECFA84E].[[email protected]].BlackDream”.
In every directory that contains the encoded files, a ReadME-Decrypt.txt file will be found. It is a ransom money note. It contains information about the ways of paying the ransom and some other information. The ransom note most probably contains instructions on how to purchase the decryption tool from the ransomware developers. You can get this decrypting software after contacting [email protected] through email. That is pretty much the scheme of the felony.

How did Blackdream ransomware end up on my PC?
There is a huge number of possible ways of ransomware infiltration.
Nowadays, there are three most popular ways for hackers to have ransomware settled in your system. These are email spam, Trojan introduction and peer file transfer.
- Another thing the hackers might try is a Trojan horse model. A Trojan is a program that gets into your machine pretending to be something else. For instance, you download an installer for some program you want or an update for some service. But what is unboxed reveals itself a harmful agent that encodes your data. As the installation file can have any name and any icon, you have to make sure that you can trust the source of the things you’re downloading. The optimal thing is to use the software developers’ 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 Internet. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded items with the anti-malware utility as soon as the downloading is finished.
How do I get rid of ransomware?
It is crucial to note that besides encrypting your data, the Blackdream virus will probably install Vidar Stealer on your machine to seize your credentials to different accounts (including cryptocurrency wallets). The mentioned spyware can extract your logins and passwords from your browser’s auto-filling data.
How сan I avoid ransomware attack?
Blackdream ransomware doesn’t have a superpower, neither does any similar malware.
You can armour your PC from its attack within several easy steps:
- Never open any letters from unknown mailers with strange addresses, or with content that has likely no connection to something you are expecting (can you win in a money prize draw without even taking part in it?). If the email subject is likely something you are waiting for, scrutinize all elements of the questionable email with caution. A fake email will always contain a mistake.
- Do not use cracked or untrusted software. Trojan viruses are often distributed as a part of cracked products, most likely as a “patch” preventing the license check. Understandably, potentially dangerous programs are difficult to distinguish from reliable software, because trojans sometimes have the functionality you need. You can try to find information on this program on the anti-malware message boards, but the optimal solution is not to use such programs at all.
Frequently Asked Questions
🤔 Is it possible to open “.BlackDream” files?
Unfortunately, no. You need to decipher the “.BlackDream” files first. Then you will be able to open them.
🤔 What should I do to make my files accessible as fast as possible?
It’s good if you have fаr-sightedly saved copies of these important files elsewhere. 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. The rest of the methods require patience.
🤔 What actions should I take if the Blackdream malware has blocked my PC and I can’t get the activation key.
🤔 What could help the situation right now?
Some of the encrypted files can be found elsewhere.
- If you sent or received your important files by email, you could still download them from your online mail server.
- You may have shared photographs or videos with your friends or relatives. Simply ask them to give those images back to you.
- If you have initially downloaded any of your files from the Web, you can try to do it again.
- Your messengers, social media pages, and cloud drives might have all those files as well.
- Maybe you still have the needed files on your old computer, a laptop, cellphone, memory stick, etc.
HINT: You can use file recovery utilities1 to get your lost data back since ransomware arrests the copies of your files, deleting the original ones. In the video below, you can learn how to recover your files with PhotoRec, but remember: you won’t be able to do it before you eradicate the ransomware itself with an anti-malware program.
