What is Bl4ack ransomware?

Bl4ack ransomware – cryptovirus that doesn't append any extensions to locked files

Bl4ack ransomwareBl4ack ransomware - threat that demands cryptocurrency payments.

Bl4ack ransomware is a computer virus that encrypts victim's personal files but unlike typical ransomware, doesn't append any extensions to the locked files. Such viruses are distributed with email spam, software cracking tools, malicious websites, etc. Usually, most ransomware receives their names from the appendixes they append to filenames, for instance, Zimba, Lola, Jdyi, this culprit received its name from the contact ID that is left in its ransom note – bl4ack#1337.

Typical ransom notes consist of threats, instructions, explanations, that's not the case with Bl4ack ransomware virus. When it finished encrypting files, a pop-up window jumps out of nowhere, informing the victims that all personal files, such as documents, pictures, music, etc, have been encrypted and that the only way to retrieve access to those files is by getting a decryption key from the cybercriminals.

Users are urged to contact the criminals via instant messaging app Discord[1] with their given ID – bl4ack#1337. No info on used algorithms, no ransom amount, or preferred payment method specifications. At the bottom of the pop-up window is a timer running down. We can only speculate what it's meant for and what happens when the time runs out, maybe the files will be deleted, maybe the price will rise, maybe the files will unlock themselves, who knows. Bl4ack file virus creators cannot be trusted, but do not panic.

Contacting the developers of Bl4ack ransomware and paying for the decryption key might seem like the easiest out of this unpleasant situation, but it's the worst thing that an owner of an infected device could do. The FBI warns the victims not to comply with the criminals' demands as that only motivates them to increase the volume of their attacks, and furthermore, ransom payments finance their whole operation, so the cybercriminals can develop more complex ransomware.

We advise using SpyHunter 5Combo Cleaner or Malwarebytes apps to perform a full scan and automatically remove Bl4ack ransomware from your infected computers immediately. The longer any malware stays in a device the more harm it could do. Anti-malware software must be updated regularly so it could detect the latest threats.

A short message from the cybercriminals in the Bl4ack ransomware pop-up window:

– And now?

Now you need to contact bl4ack#1337 on the discord asking for the decrypt key

– is there another way for me to recover my files?

No. only with our key we can recover your files



Spam emails – one of the main techniques of ransomware distribution

We've all received spam emails in our lifetimes. Email service providers even have a separate folder for that trash. But cybercriminals are a creative bunch and sometimes the email security systems overlook some of these emails and let them through. No matter if their in your spam folder or in your inbox, spam mail should never be opened.

Most malware is hidden either in the infected attachments or in hyperlinks. Don't download any attachments without scanning them first with reliable anti-virus software. Hyperlinks might redirect you to a malicious site where your computer will automatically download a virus payload file. So refrain from clicking on any links unless you're 100% sure it's to a secure site.

Bl4ack virusBl4ack ransomware is the virus that creates issues with the system with background processes.

Some of the spam emails might even seem like legitimate letters from your bank or shipping company. Keep in mind that companies don't usually send out emails with hyperlinks urging you to push them, access your accounts, and so on. Look carefully, maybe there are some grammatical mistakes or some other visible irregularities.

Guidelines for Bl4ack ransomware virus removal

All ransomware should be eliminated as soon as it's either caught by anti-malware software or at the first sight of a ransom note. There are various types of malware but none of it is a welcomed guest on any computer system. To remove Bl4ack ransomware and all its allocated files from an infected device, we suggest using time-tested reliable anti-malware apps like SpyHunter 5Combo Cleaner and Malwarebytes.

Regrettably, Bl4ack ransomware removal won't decrypt your files. There's no public decryption key available at the moment. If you didn't have backups, export all personal files to an offline storage, like a USB or any other of this type, and come back to check on us as we update our subscribers with all the latest news.

If you had backups, then the whole process is a bit easier. Before restoring your data, experts[3] highly recommend using the FortectIntego application to repair any damage that the virus might have done to system core files and settings.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
