Uninstall BBOO virus (Virus Removal Tutorial) - Decryption Methods Included

Description of BBOO ransomware removal guide

BBOO ransomware – a dangerous computer infection that may result in complete loss of personal files

BBOO ransomware is a file locking virus that stems from the notorious malware family Djvu

BBOO ransomware is a file locking virus that stems from a notorious family Djvu/STOP and is usually spread via pirated software installers or cracks/keygens. Once inside the system, the malware performs a variety of changes to it and then begins to look for files to encrypt. As a result, all pictures, documents, databases, and other data receive a .bboo file extension, and the owners can no longer access it.

To ensure that users are aware of what happened to their files, malicious actors behind the BBOO virus also provide a ransom note _readme.txt, which is placed inside almost every folder, as well as the desktop. Inside, hackers ask victims to contact them via the helpdatarestore@firemail.cc or helpmanager@mail.ch emails, and then pay $490 for the BBOO ransomware decryptor.

If you got infected with BBOO ransomware, you should not rush paying cybercriminals, as we will provide instructions that may help you retrieve data using alternative methods listed below.

Djvu/Stop ransomware has a long history in the cybercriminal world and is now a well-established illegal business for actors behind it. At the time of the writing, there are over 200 variants released, with at least two being produced each week. Cybercriminals keep releasing new versions because thousands of users get infected, and some are willing to pay the ransom, making it a lucrative business. BBOO ransomware is 205th version of the virus spotted in the wild – previous ones include:

• Alka
• Repp
• Btos
• Npsg
• Topi, etc.

BBOO ransomware removal is vital for every infected system, as cybercriminals are known to insert additional malware modules that can steal sensitive data from various web browsers, such as Google Chrome, Mozilla Firefox, or Internet Explorer. Due to this component, users may expose their credentials, banking information, and other sensitive data to cybercriminals, which can result in devastating consequences such as money loss or even identity theft.

Additionally, BBOO ransomware is also programmed to modify Windows “hosts” file in order to prevent users from visiting security-related websites that could help them deal with the infection and provide alternative methods for file recovery. To revert this, users should visit the following folder and delete the “hosts” file – it will be recreated by Windows automatically, although the malware-added IPs will be removed:

C:\Windows\System32\drivers\etc\

Besides, some variants of this ransomware were distributed with another malware, such as data-stealer AZORult – this is another reason to remove BBOO ransomware as soon as possible (important note: if you have no backups to restore your files from, make a copy of encrypted files before removing malware from your computer, as this action may permanently damage data without any chance of recovery). After you get rid of malware, scan your machine with RestoroIntego to ensure it recovered promptly – this will prevent any stability or functionality issues.

BBOO ransomware is a type of malware that locks all personal files on targeted device and then blackmails users to pay for the decryption tool

System modification and file encryption

As soon as the BBOO ransomware virus starts the infection routine, it begins to prepare the system for the file encryption process. The virus performs the following changes:

• Modifies Windows registry to establish persistence
• Deletes Shadow Volume Copies with the help of “vssadmin delete shadows /all /quiet” command
• Contacts a remote Command-and-Control server and makes several other HTTP requests
• Drops multiple malicious files into %LocalAppData%, %Temp%, %WinDir% and other folders, etc.

As soon as the necessary changes are complete, BBOO ransomware will begin a full system scan, looking for predetermined file types, such as .doc, .pdf, .jpg, .mp4, .rar, and many others. During this time, the virus will show a fake Windows Update window in order to prevent users from interrupting the procedure.

After the encryption process, users will be immediately presented with the ransom note _readme.txt, which reads:

BBOO ransomware: file recovery options

BBOO ransomware belongs to the newer surge of Djvu ransomware viruses that use more advanced encryption with the help of the asymmetric RSA cypher. Before August 2019, most of the malware versions applied the AES algorithm, which was relatively weak – this served as a major breakthrough when it came to data decryption options, as security experts from Emsisoft managed to create a decryptor that worked for 148 versions.

Unfortunately, the RSA-encrypted files were secured more tightly. Since BBOO ransomware came out in early February 2020, it can no longer be decrypted. Emsisoft, however, also provides an alternative tool that can help some users, even if they were infected with a version released past August 2019.

As soon BBOO virus finishes encrypting data, the only secure way of recovering it is by using backups

For that tool to work, the BBOO virus should have failed to contact its C&C server, which can happen due to various reasons, including victims ' bandwidth problems, or if the encryption process was interrupted. There is no particular way to establish whether an offline ID was used, so the only way to find out is to try using the decryptor.

If BBOO encrypted files with an online ID, data recovery without paying hackers is low. However, you can attempt to recover at least some files with data recovery tools or make use of built-in features like Windows Previous Version. For comprehensive instructions, please refer to our recovery section below.

Even if none of the above helped you, you should not lose hope. Security experts are constantly working on free decryption software, and a working tool for BBOO ransomware may be released in the future.

Software cracks and pirated software installers – the main ransomware attack vector

Users often ignore cybersecurity experts' advice and proceed to risk their online safety by neglecting basic malware prevention measures. As a result, they infect their machines with such dangerous malware like ransomware, and then ask for help, although it might be a little too late, as ransomware does not revert changes to data, even after it is removed. Therefore, it is best to listen to industry experts to prevent permanent data loss, as well as other negative consequences.

Most of Djvu variants are spread with the help pirated software installers, and software cracks/keygens such as KMSpico – these tools are designed to bypass the licencing process of the program, which allows its free usage. However, these files can often be booby-trapped with malware, and most of the security software will flag cracks as malicious regardless if they include malware payload or not. Thus, there is no way to check whether the installer is actually malicious.

For that reason, we highly advise you staying away from software cracks and unsolicited installers, as these are often malicious. Instead, download and alternative software that is free to use, or purchase a licence for a program you wanted initially. Besides this, you should always practice additional security measures:

• When dealing with spam email attachments do not allow a macro function to run; do not click on hyperlinks inside a suspicious email
• Keep Windows and all the other programs on your computer updated with latest security patches
• Employ comprehensive security software with real-time protection feature
• Use two-factor authentication where possible, and never reuse passwords for different accounts
• Backup your files on a regular basis.

BBOO ransomware removal instructions

Before you proceed with BBOO ransomware removal, you should first consider whether you have a working backup. Under no circumstances connect to a remote server or external storage that holds your files, as these will also be encrypted by ransomware. However, if you have no backups, you should not get rid of BBOO virus just yet.

If you remove BBOO ransomware immediately, the encrypted data may become permanently damaged. As a result, even a working decryption tool will not be able to help you. Thus, backup the locked data, and only then scan your machine with a reputable anti-malware software, such as SpyHunter 5Combo Cleaner or Malwarebytes. A full system scan will ensure that all the malicious files are deleted correctly. Note that, in some cases, ransomware may interfere with your security software; if that happens, access Safe Mode with Networking as explained below.

After you are sure that BBOO file virus is eliminated, you can then attempt to recover your data with the help of Emsisoft's decryptor or third-party recovery tools.
