Bbbw ransomware is a dangerous computer virus. It targets computer files such as documents, presentations, spreadsheets, drawings, archives, databases, photos, images, and other common user’s data. Like most ransomware, Bbbw virus is aiming to extort money from computer users by denying them access to files. In order to accomplish this task, Bbbw ransomware was designed to apply a highly complex algorithm to encrypt the data, and at the same time, it altered the format by appending bbbw file extension. As a result, the common file abc.doc will turn into abc.doc.bbbw.
How does the Bbbw virus infect the computer?
Attackers are employing different campaigns to deploy Bbbw ransomware. This variant of STOP/DJVU malware can arrive on the computer via spam email messages, drive-by-download techniques, cracked programs, malicious freeware, social engineering attacks, Trojan Dropper, and dubious advertisements. Below are the details.
Spam email messages masking from a valid organization may arrive in the inbox with Bbbw ransomware as an attached file. Of course, the virus is under the guise of valid documents, so the recipient will not be suspicious. Upon opening the attached file, Bbbw virus initiates the infection without notice.
Drive-by-download techniques, also known as web injectors, are infected websites that hackers are using to infect the visitors computers with Bbbw ransomware. Malicious scripts on the said website automatically download the virus by exploiting certain vulnerabilities in internet programs.
Cracked Software that computer users are downloading from different sources may have Bbbw ransomware. Aside from being unlawful, installing these maliciously modified applications can be the source of virus infection. The same thing goes with dubious freeware that several questionable websites are offering as a free download.
Social engineering attacks can easily trick user because the file or malicious links were sent from legitimate contacts. The receiver, who often falls victim to this trick, are not aware that the account of the other party is hacked or mimicked by attackers.
Trojan Dropper is a minor virus that is able to conceal themselves from security applications. Once inside the computer, it communicates with a remote server to download a copy of Bbbw ransomware. It basically serves as advanced party and because its obscure presence, it can freely perform various malicious actions on the infected computer.
Bbbw file encryption/decryption
The moment that Bbbw ransomware is active on the system, it sends a report to command-and-control (C&C) server. Then, the server sends back command to initiate the encryption process and at the same time, it provides a public key for this specific infected computer. Bbbw ransomware will proceed with the file-locking actions using a sophisticated algorithm. This will make it impossible for users to access or open the infected files.
A ransom note file called readme.txt is generated as a notice about the current infection. It also contains instructions on how to retrieve Bbbw decryption tool that is in the possession of attackers. As with the majority of ransomware attack, makers of Bbbw demand money as payment for the recovery program and private keys that are needed to accomplish a successful file decryption.
| Threat Name | Bbbw Ransomware, STOP/DJVU |
|---|---|
| Threat Type | Crypto-virus, File Locker, Encryption Virus |
| File Extension | .bbbw |
| Ransomware Note File | _readme.txt |
| Attacker’s email | helpmanager@mail.ch restoremanager@airmail.cc |
Backup your files
One important step before proceeding with the procedures below is to backup your files. Ransomware attacks are not the same. Each has its own unique set of payloads, aside from encrypting the files with a complex method. Others tend to delete the infected files after a certain period, while others keep them concealed in hidden places. In addition, ransomware decryption tools are not guaranteed to be perfect, and there are instances where files suffer from damages during the decryption process.
So, it is better to create a backup copy of your entire Bbbw-encrypted files right now.

How to protect the computer from Bbbw ransomware?
After the ransomware is removed, it is important to prevent similar incidents from happening again. To effectively protect the computer, the user must know how Bbbw ransomware was able to infect it. To minimize the possibility of infection, staying away from the common sources of this virus is crucial.
How does ransomware infect your computer?
The method of infecting the computers was found to be similar to that of other common viruses. Ransomware like Bbbw is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and Trojan Downloaders.
Once the virus is executed, it immediately infects the system. Then, Bbbw ransomware communicates with a remote server so that a unique key can be generated for a specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. In the final stage of the attack, Bbbw ransomware demands ransom money in exchange for the decryption tool. To further understand the attack scheme, we have included an infographic below.
