How to avoid infecting a computer with BiBi malware
Written by Tomas Meskauskas on (updated)
What kind of malware is BiBi?
BiBi is a type of malware known as a wiper, and it targets both Linux and Windows users (there are two variants of BiBi targeting different operating systems). Wiper malware is a destructive form of malicious software designed to erase or damage data on infected systems irreversibly. A group of hackers with ties to Hamas may be responsible for creating BiBi.
More about the BiBi data wiper
BiBi wiper represents a class of malicious software designed with a singular and destructive purpose: to irreversibly erase or damage data on infected systems. Unlike other types of malware that may focus on data theft, surveillance, or financial gain, wiper malware is characterized by its intent to cause significant disruption and destruction to targeted systems.
The primary goal is to render data and often entire systems unusable, leading to operational paralysis and data loss. Wiper malware can manifest in various forms, utilizing techniques that make data recovery challenging, if not impossible. It may overwrite critical files, modify system configurations, or encrypt data beyond recovery.
The motivations behind wiper malware attacks can vary widely, encompassing ideological, political, or strategic objectives. In the case of BiBi, it appears to be used by hackers affiliated with the Hamas group.
BiBi is noted for its selective destruction of files, excluding those bearing .exe, .dll, and .sys extensions, as these file types are integral for the proper functioning of a computer. These specific extensions are hardcoded within the malware's code, ensuring they are bypassed during the wiping process, allowing the malware to execute its intended course of destruction.
During the wiping operation, the targeted files undergo a transformation where they are filled with random bytes, rendering them both unusable and irrecoverable. The malware's functionality extends to the deletion of shadow copies within the system, presenting a significant hurdle for users attempting to recover their files unless they possess an offline backup.

Possible damage
In conclusion, BiBi emerges as a distinctive and destructive form of malware with a notable capacity for selectively targeting files crucial for a computer's functionality, while sparing essential system files with specific extensions. The malware employs a meticulous wiping process, filling targeted files with random bytes and rendering them irrecoverable.
Users and cybersecurity professionals alike are advised to remain vigilant and implement robust protective measures to mitigate the risks associated with this destructive malware.
How did BiBi infiltrate my computer?
Users may unknowingly download and execute malware when opening attachments or clicking on links received from cybercriminals via email, leading to a ransomware infection. Another avenue for malware infection is malvertising, where attackers inject malicious code into advertisements on websites. Clicking on these ads can open malicious websites or trigger the automatic download of malware.
Pirated software, cracking tools, key generators, P2P networks, third-party downloaders, etc., are other channels commonly used for malware distribution. In other cases, threat actors use Trojans or exploit software vulnerabilities to infect computers.
How to avoid installation of malware?
Exercise vigilance when receiving emails, particularly from unfamiliar or unexpected origins. Refrain from clicking on links or downloading attachments sent by unverified sources. Download apps and files from reliable sources such as official websites and stores, and avoid downloading pirated software, cracking tools, or similar content.
Do not click suspicious advertisements and pop-ups, especially while on questionable pages. Install reputable antivirus or anti-malware software on your computer. Keep the operating system, security software, and all applications up to date. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.
These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
