How to eliminate InvisibleFerret from infected systems

What kind of malware is InvisibleFerret?

InvisibleFerret is a Python-based backdoor malware associated with North Korean threat actors. Cybercriminals use it mainly for data theft and the injection of other tools for additional control. Victims of InvisibleFerret can experience issues like monetary loss, identity theft, and additional infections.

More about InvisibleFerret

InvisibleFerret starts by gathering geolocation and system details, such as the OS version, hostname, and username. It then generates a unique ID for the infected system. After that, the malware organizes its targets into five lists, helping it identify what data to steal and what to ignore.

These lists include file types, extensions, and directories that should be bypassed while focusing on valuable data to exfiltrate. Furthermore, InvisibleFerret lets attackers send commands to the infected system, execute them remotely, and download and run additional payloads.

It is known that InvisibleFerret can download and run AnyDesk, a legitimate remote administration tool, on infected systems to give attackers more control. Furthermore, it targets browser data from various browsers (such as Brave, Chrome, Chromium, Edge, Opera, and Vivaldi), including profiles, cookies, and credentials.

Additionally, it focuses on extracting data from crypto wallets (Metamask), authentication apps (Google Authenticator), and password managers (1Password). Other capabilities include using libraries to monitor clipboard activity, capture keystrokes, and track mouse movements.

With the information stolen by InvisibleFerret, cybercriminals can access personal accounts, including email, social media, and financial services, by compromising login credentials and other data. They can also steal funds from cryptocurrency wallets like Metamask and access sensitive data in password managers.

Additionally, cybercriminals can monitor clipboard activity to capture banking or payment details, passwords (and other sensitive information), inject more malicious payloads, and perform other malicious activities.

Possible damage

InvisibleFerret is a dangerous malware capable of stealing sensitive data from browsers, password managers, and cryptocurrency wallets. It provides attackers with remote control over infected systems and enables ongoing exploitation by executing commands and downloading additional malicious tools. It can cause issues like monetary loss, identity theft, account takeover, data loss, and more.

How did InvisibleFerret infiltrate my computer?

Cybercriminals use fake job interviews to target developers in the tech, finance, and cryptocurrency sectors. They stage fake interviews where the victim is tricked into downloading malicious files. These files can appear as coding challenges or video call software.

One of the malicious programs used in this attack is BeaverTail, a JavaScript-based malware. Once BeaverTail infiltrates systems, it deploys InvisibleFerret, which carries out data theft and other malicious actions.

How to avoid installation of malware?

Always be cautious when downloading files or software. Use official websites or app stores for downloads instead of unknown or untrusted sources. Avoid clicking email links or opening attachments in unexpected, irrelevant emails from suspicious addresses. Regularly update your operating system, software, and antivirus programs to protect against potential vulnerabilities.

Do not trust advertisements, pop-ups, and similar content on dubious web pages. Lastly, stay informed about the latest cybersecurity threats and best practices. 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.

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 Combo Cleaner Antivirus 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:

If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:

Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

Restart your computer into Safe Mode:

Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

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.
