BLADABINDI virus removal guide

What is BLADABINDI?

BLADABINDI is a backdoor threat, designed to inject systems with malicious payloads. In other words, following successful infiltration, it stealthily downloads/installs malware onto affected systems. At the time of research, BLADABINDI had been observed being proliferated bundled with Windscribe VPN installers. "Bundling" is the term used to describe a deceptive marketing technique of packing ordinary software with unwanted or malicious additions. Windscribe is a legitimate cyber-security and privacy company, offering tools geared towards device and online security/privacy. It must be emphasized that the BLADABINDI backdoor bundled with the aforementioned VPN application was not distributed through official channels (e.g. Windscribe's website, Google or Apple stores); cyber criminals pushed the modified installers through various unofficial and third party download sources.

As mentioned in the introduction, the primary functionality of the BLADABINDI backdoor is causing chain infections (i.e. download/install additional malware). Hence, through this backdoor a compromised system can be infected with trojans, ransomware, cryptominers and other malicious programs. To elaborate, BLADABINDI can download and execute files, as well as update them. The backdoor can also extract computer data, such as: device name, operating system details (e.g. version, architecture, etc.), and system account username. BLADABINDI can detect installed anti-virus tools installed onto the system as well. Another feature of this backdoor is taking snaps of the screen (i.e. screenshots). To summarize, BLADABINDI infections can lead to a wide variety of problems, including (but not limited to): device/data damage, financial losses, severe privacy issues and identity theft. If it is known or suspected that BLADABINDI (or other malware) has already infected the system - an anti-virus must be used to eliminate it immediately.

GroooboorUpatreBazarBackdoorBerbew and Buer Loader are some examples of malicious programs, which operate as backdoors for other malware. Malicious software can have a wide variety of functionalities that can be used in likewise varied ways, depending on the cyber criminals' goals and modus operandi. However, regardless of how such programs operate, the end-goal is always the same - to generate revenue for their developers and criminals using them.

How did BLADABINDI infiltrate my computer?

BLADABINDI was spread through deceptive installers, disguised as the Windscribe VPN installation setups. The bundled installer consisted of the legitimate Windscribe VPN install setup, malicious file containing the backdoor ("lscm.exe"; filename may vary) and an app operating as the runner for the virulent file ("win.vbs"; may vary). The fake installation setups were distributed through untrustworthy download sources. Malware and other dangerous/untrustworthy content is often spread through dubious download channels, e.g. fake, unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders. This dangerous content is typically disguised as or bundled with ordinary products. However, malicious software is also proliferated via illegal activation ("cracking") tools, fake updaters and spam campaigns. "Cracking" tools can download/install malware, instead of activating licensed product. Fake updaters infect systems by exploiting flaws of outdated products and/or by installing malicious programs, rather than the promised updated. Spam campaigns are mass-scale operations, during which scam emails are sent by the thousand. The deceptive letters contain download links of infectious files and/or the files are simply attached to the emails. These files can be in various formats (e.g. executables, archives, PDF and Microsoft Office documents, JavaScript, etc.) and when they are executed, run or otherwise opened - the infection process/chain (i.e. malware download/installation) is triggered.

How to avoid installation of malware?

It is highly recommended to only use official and verified download sources. Untrustworthy download channels are advised against use, as they commonly offer deceptive and malicious content. It is just as important to activate and update products with tools/functions provided by genuine developers. Since illegal activation tools ("cracks") and third party updaters are often used to proliferate malware. Additionally, suspicious and/or irrelevant emails must not be opened, especially any links or attachments found in them - as that can result in a high-risk system infection. To ensure device and user safety, it is paramount to have a reputable anti-virus/anti-spyware suite installed. Furthermore, this software must be kept up-to-date, used to perform regular system scans and to remove detected/potential threats. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check 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".

locate the malware file you want to remove

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.

searching for malware file on your computer

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 Malwarebytes for Windows.
