How to remove BATLOADER malware

Also Known As: BATLOADER virus
Type: Trojan

What kind of malware is BATLOADER?

BATLOADER is part of the infection chain where it is used to perform the initial compromise. This malware is used to execute payloads like Ursnif. Our team has discovered BATLOADER after executing installers for legitimate software (such as Zoom, TeamViewer Visual Studio) bundled with this malware. We have found those installers on compromised websites.


BATLOADER malware in detail

The purpose of BATLOADER is to download and execute the next stage payloads. Those payloads include Ursnif, BEACON (Cobalt Strike’s default malware payload), Atera (Remote Monitoring & Management software).

After analyzing the infection chain, we learned that BATLOADER is used as a stepping stone to execute malicious and non-malicious software. Cybercriminals use it to drop payloads allowing them to log keystrokes, collect saved logins/passwords, web browsing activity, system information, and perform other actions.

More about BATLOADER

The BATLOADER malware starts a multi-stage infection chain using commonly abused Windows binaries to download and execute further payloads. We found that most of the final payloads are used to establish remote access and persistence.

How did BATLOADER infiltrate my computer?

Threat actors use an SEO poisoning technique to trick users into downloading installers (for TeamViewer, Zoom, Visual Studio, and possibly other software) bundled with BATLOADER. Those installers are distributed using compromised websites that appear in search results after entering certain keywords. Those keywords include “free productivity apps installation” or “free software development tools installation”.

How to avoid installation of malware?

Do not use installers for cracked software or cracking tools to bypass software activation. Update and activate the software with tools provided by the official developers. Download software from official pages and direct links. Avoid using sources such as unofficial pages, third-party downloaders, P2P networks as sources for downloading files/programs.

Do not open links or attachments received from unknown email addresses (especially when received emails are irrelevant). Do not click on ads and fake buttons while visiting shady websites. 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.

Update June 23, 2023 – new BATLOADER campaigns have been observed. The malware is used to infect devices with a variant of Mallox ransomware (".malox"). This is the first instance that BATLOADER proliferates ransomware. The infection begins with a malicious attachment sent in a phishing email. The attached file can either be BATLOADER's executable or one that downloads this malware.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

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.

Search for malware and delete 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.
