More about BunnyLoader

BunnyLoader is malicious software operated through a command-and-control (C2) panel. It can be directed to download and run additional malicious software onto the infected machine, potentially expanding its capabilities. Also, BunnyLoader is capable of recording keystrokes made by the victim, thereby capturing sensitive information such as usernames, passwords, and other input.

Furthermore, BunnyLoader is designed to extract login credentials and system-related data from the compromised system, potentially compromising user accounts and system security. It can monitor and manipulate the victim's clipboard, particularly for cryptocurrency-related activities. This enables it to replace cryptocurrency wallet addresses with addresses controlled by the attackers, potentially leading to financial losses for victims.

The malware can access and extract AutoFill data, downloads, history, passwords, and credit card details from numerous web browsers, including Chrome and Microsoft Edge.

It is known that BunnyLoader targets the following cryptocurrency wallets: AutomaticWallet, Armory, Bytecoin, Coinomi, Electrum, Ethereum, Exodus, Guarda, and Jaxx. BunnyLoader also illicitly acquires credentials from the OpenVPN and ProtonVPN clients. Additionally, it pilfers credentials from Element, ICQ, Signal, Skype, and Tox messaging applications.

BunnyLoader has the ability to execute remote commands on the infected machine, granting attackers control over various aspects of the compromised system.

Users of BunnyLoader can access statistics that provide insights into the extent of infections, allowing them to gauge the impact and reach of their malicious activities. The panel tracks the total number of connected and disconnected clients, providing real-time information about the state of compromised machines.

Threat actors can manage active tasks initiated by BunnyLoader, giving them control over ongoing malicious operations. Also, BunnyLoader maintains logs of its data-stealing activities, enabling users to review and potentially exploit the sensitive information captured during its operations.

How did BunnyLoader infiltrate my computer?

Users may unknowingly download malware when clicking suspicious links or downloading files from untrustworthy websites. Cybercriminals often send deceptive emails that appear legitimate but contain malicious attachments or links. Users can inadvertently infect their computers with malware when they click on these links or download attachments.

Failing to update operating systems, applications, and antivirus software can leave computers vulnerable to security exploits. Cybercriminals can take advantage of these vulnerabilities to gain access to the system.

Users who engage in risky online behavior, such as clicking on pop-up ads and visiting suspicious websites, increase the likelihood of infecting their computers. Inserting infected USB drives or external storage devices into a computer can also introduce malware to the system.

How to avoid installation of malware?

To safeguard against computer infections, users should adopt secure online practices, ensure their software remains up to date, and employ trustworthy antivirus and security solutions. Furthermore, exercising prudence when dealing with emails, advertisements, and downloads from unfamiliar origins is essential to avoid unintentional computer infections.

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.

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.

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.
