BLACKSKULL Ransomware 🔐 [email protected]

The Blackskull ransomware is a harmful program that encrypts all your data on a Windows PC (photos, text files, excel tables, audio files, videos, etc) and appends its specific extension to every file, creating the Recover_Your_Files.html text files in every folder with the encrypted files.

What is Blackskull virus?

Blackskull will add its extra .BlackSkull extension to every file’s title. For example, a file entitled “photo.jpg” will be changed to “photo.jpg.BlackSkull”. Just like the Excel file with the name “table.xlsx” will be renamed to “table.xlsx.BlackSkull”, and so on.

In each folder that contains the encrypted files, a Recover_Your_Files.html file will appear. It is a ransom money note. It contains information about the ways of contacting the racketeers and some other remarks. The ransom note usually contains a description of how to purchase the decryption tool from the racketeers. You can obtain this decryptor after contacting [email protected] by email. That is how they do it.

How did my machine catch Blackskull ransomware?

There is a huge number of possible ways of ransomware injection.

Nowadays, there are three most exploited ways for hackers to have ransomware settled in your system. These are email spam, Trojan infiltration and peer-to-peer networks.

  • Another option for ransom hunters is a Trojan file scheme. A Trojan is an object that gets into your computer disguised as something different. For instance, you download an installer for some program you need or an update for some service. But what is unboxed reveals itself a harmful agent that corrupts your data. Since the update file can have any title and any icon, you have to make sure that you can trust the resource of the files you’re downloading. The optimal way is to trust the software companies’ official websites.
  • As for the peer networks like torrents 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. So you’d better be using trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded files with the anti-malware utility as soon as the downloading is finished.

How to remove ransomware?

It is crucial to inform you that besides encrypting your files, the Blackskull virus will probably install Vidar Stealer on your computer to get access to credentials to different accounts (including cryptocurrency wallets). That spyware can extract your credentials from your browser’s auto-filling data.

How do I avoid ransomware attack?

Blackskull ransomware has no endless power, so as any similar malware.

You can protect your computer from its injection taking several easy steps:

  • Ignore any emails from unknown mailers with strange 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, scrutinize all elements of the dubious email with caution. A fake letter will always contain mistakes.
  • Never use cracked or untrusted programs. Trojans are often shared as a part of cracked software, possibly as a “patch” to prevent the license check. But potentially dangerous programs are difficult to distinguish from trustworthy software, as trojans sometimes have the functionality you need. Try to find information on this software product on the anti-malware message boards, but the optimal solution is not to use such software.

Frequently Asked Questions

🤔 How can I open “.BlackSkull” files?Is it possible to open“.BlackSkull” files?

Unfortunately, no. You need to decipher the “.BlackSkull” files first. Then you will be able to open them.

🤔 I really need to decrypt those “.BlackSkull” files ASAP. How can I do that?

If the “.BlackSkull” files contain some really important information, then you probably have them backed up. 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 to do if the Blackskull ransomware has blocked my PC and I can’t get the activation code.

🤔 What can I do right now?

Many of the encoded files might still be within your reach

  • If you sent or received your critical files via email, you could still download them from your online mail server.
  • You might have shared photographs or videos with your friends or relatives. Just ask them to send those images back to you.
  • If you have initially got any of your files from the Internet, you can try to do it again.
  • Your messengers, social media pages, and cloud storage might have all those files as well.
  • Maybe you still have the needed files on your old PC, a notebook, phone, memory stick, etc.

USEFUL TIP: You can use data recovery programs1 to get your lost data back since ransomware encrypts the copies of your files, deleting the authentic ones. In the video below, you can learn how to recover your files with PhotoRec, but be advised: you can do it only after you eradicate the virus with an antivirus program.
