Jokeroo virus Removal Guide

What is Jokeroo ransomware?

Jokeroo is a notorious ransomware which is using scamming techniques to leave victims with nothing

Jokeroo ransomwareJokeroo - dangerous ransomware which started promoting itself as GandCrab Ransomware RaaS on Exploit.in

Jokeroo is a ransomware-as-a-service offering its code as a convenient way to launch cryptoviruses.[1] This threat has been actively spread via underground hacking sites or social networks, including Twitter.[2] The ransomware virus first pretended to be a variant of the infamous GandCrab and presented itself as a GandCrab RaaS on an underground website, known as Exploit.in. However, sometime after that, the cybercriminals changed the name to Jokeroo RaaS and started advertising it on the Twitter social network. Recently, virus developers started claiming that they were seized by the Royal Thai Police, the Dutch National Police, and Europol. However, this is far from true and such declarations are, most likely, used to leave people with no money and no encryption key.

Name Jokeroo
Type Ransomware/RaaS
Also known as Its developers were claiming that the virus is GandCrab RaaS
Infiltration sources Spam, infected links, illegal sites
Main goal To convince users to pay for the encryption key
Price The membership for the RaaS costs from $90 to $600, the ransom varies
Detection If infected, don't pay the ransom. Virus developers are now using an exit scam to leave users with no data, money, and decryption key. Use ReimageIntego to scan your machine for ransomware files and then use backups to recover your data

The bad guys hiding behind Jokeroo ransomware have one main goal – to spread their infection as far as possible. To achieve such goal, cybercriminals try to convince other hackers to spread the ransomware infection further to other users. Crooks offer to buy a membership package which includes different abilities and costs from $90 to $600.

Talking about the $90 price membership, the affiliate receives a big variety of functions which are included in the package. He/she becomes able to choose the encryption extension, create a ransom message, generate one new ransomware virus of his/her own, manual spreading, also demanding and receiving a ransom in Bitcoin which 15% goes to the cybercriminals' pockets:

You can change and customize your ransomware

Change all the logo, An icon in format .ICO, Remove the jokeroo logo
You can choose the extension
A description to help the victim in format .TXT

Spread manually

We will touch 15% fees ransom
You will be able to manage all the victims since the dashboard
Display: CD key, PC Name, Encrypted files, Operating System (OS)
Lifetime license !

However, talking about users who decided to benefit from Jokeroo ransomware, they additionally are offered to buy more functions for $300 or $600. For such a free, potential hackers can receive Salsa20 encryption algorithm to make victim's files useless, an ability to use a set of different ransomware versions and different type of cryptocurrency, not only Bitcoin, used as a ransom, etc.

Unfortunately, all these techniques can increase the chances of getting infected. While at the moment hackers are claiming that they were blocked by different authorities, there is a higher chance that hackers are working on an exit scam technique. In this case, hackers claim that they were locked and vanish away with money collected from victims.[3]

However, if you ever suspect that this ransomware virus has entered your system in some type of way, you should take immediate actions to terminate it from the system. The longer it stays, the more files you can lose without a chance to recover them. There is a high chance that hackers can't recover users' data and that there is no decryptor created by them.

To detect malicious content, use anti-malware programs, such as ReimageIntego or SpyHunter 5Combo Cleaner. After that, remove Jokeroo from your machine automatically. For recovering your files, use third-party tools provided at the end of this post. We cannot guarantee that they will help, but you should try them at first. The easiest way to get your data back is by using backups saved in external drives or clouds. However, Jokeroo ransomware removal should be your first step after being infected.

Jokeroo virusJokeroo ransomware - a RaaS which is using scams to leave victims with no files and money

The ransomware-related payload is mostly found in spam messages

If you have ever been infected with a dangerous file-encrypting threat, you might have wondered from where it had come. According to Virusai.lt computer specialists,[4] ransomware is a virus form which is capable of tricking naive people and invading the system by convincing users to open suspicious payload that comes attached to email messages.

Crooks often attach an infected executable file or any other type of document to a spam message.[5] They also might insert a damaging hyperlink inside the email letter itself. Additionally, these hackers sometimes pretend to be from reliable and well-known organizations and send their letters to the inbox section which gives the look of legitimacy.

We recommend deleting all email messages that look questionable to you and investigating all that you were not expecting to receive. Additionally, you should get an antivirus program on your computer system and scan all email attachments to check if they are safe to download and open or if something malicious is hiding in them.

Terminate Jokeroo ransomware if you have found it on your machine

If, in any case, you discover Jokeroo ransomware on your system, we recommend performing virus elimination. Don't deal with virus developers as this threat has been spread as a RaaS, so there is no information about virus developers. Besides, there is a high chance that they will be very unprofessional as the membership can be bought for $90.

Jokeroo removal can be performed by downloading and installing one of these tools:

If Jokeroo ransomware virus has managed to touch some of your files on the infected computer system, you should try data recovery methods to restore the blocked information back to its starter position.

If your files are encrypted by Jokeroo, you can use several methods to restore them:

The Data Recovery Pro tool might help you with file restoring:

Try using this method to recover some of your encrypted files. Perform each step exactly as shown in the instructions in order to reach the best results possible.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Jokeroo ransomware;
  • Restore them.

Using the Windows Previous Versions feature tool might help you with data recovery purposes:

This method is created to take care of your encrypted data and bring it back to normal. However, you need to know that the tool might not work properly if you did not activate the System Restore feature in the past.

How to prevent from getting Jokeroo ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
