How to remove E4del RAT from the operating system

What kind of malware is E4del RAT?

E4del RAT is a Remote Access Trojan (RAT) that hides inside a genuine, digitally signed Discord application. Once installed, it lets attackers watch the victim's screen in real time, run commands, capture screenshots, and drop additional malware onto the machine.

The RAT was uncovered by the SOCRadar Threat Research Unit (STRU) in August 2026, alongside a second trojan called PINHOLE. Both were delivered through a novel technique that hides attacker instructions inside FTP server welcome banners.

Because E4del runs under a legitimate Discord process and never draws a window on screen, victims typically have no idea it is there.

E4del RAT overview

According to research published by SOCRadar, E4del RAT arrives through a multi-stage chain that starts with a malicious shortcut file. The shortcut connects to a rogue FTP server and reads commands hidden in the server's banner, which in turn trigger a PowerShell script that downloads and unpacks the payload.

What gets launched is a real, digitally signed Discord executable. The attackers keep the genuine program files but swap out the application's internal code archive, so Windows sees a trusted, signed program while malicious code runs inside it.

E4del is written in Node.js and runs on the Electron framework that Discord is built on. It starts with hidden-window switches so no interface is ever rendered, reducing it to a silent background process.

What can E4del RAT do?

E4del RAT supports eight operator commands. The most invasive is live desktop streaming: the attacker supplies an address, and the RAT captures the screen every two seconds and pipes the images over a WebSocket connection, creating a hidden remote view of everything the victim does.

It can also open a hidden command prompt that stays alive in the background. The operator types commands into it and receives the output on the next check-in, giving them an interactive shell on the machine.

Screenshots can be captured on demand and sent back as compressed images. Two separate commands let the attacker deliver additional payloads: one fetches a ZIP archive, unpacks it with PowerShell, and launches whatever executable it names, then deletes the archive to hide the traces.

An elevate command attempts to gain administrator rights by loading a separate module downloaded beforehand. Anything the RAT does not recognize as a known command is simply passed straight to the Windows shell and executed.

Persistence and defense evasion

E4del establishes persistence through Electron's own startup settings, registering the host Discord executable to launch automatically every time the user logs in. Because the autostart entry points at a legitimate signed application, it looks unremarkable in startup lists.

The RAT also uses a simple but effective anti-analysis check. It expects to be started with the victim's Windows username as an argument, and if the username on the machine does not match, it shuts down at once. This prevents it from detonating inside automated sandboxes.

Before contacting the attacker, E4del profiles the machine. It builds a unique hardware fingerprint from the network adapter addresses and the CPU model, then checks the system for installed antivirus products so the operator knows what security software is in the way.

All traffic to the Command and Control server is encrypted and sent as HTTP POST requests carrying a spoofed Google Chrome browser identity. The RAT varies its check-in speed between fast, medium, and slow modes depending on how recently it received a task, helping its traffic blend into normal activity.

Conclusion

E4del RAT gives attackers a hidden live view of the victim's desktop, an interactive shell, and the ability to install further malware at will. Anything typed, opened, or displayed on the infected computer can be observed and recorded.

Because it hides behind a genuine signed application and shows no window, an infection can go unnoticed for a long time. If you suspect your computer is affected, it should be scanned and cleaned immediately.

More examples of RATs are Golden Gh0st, Heisenberg, and TONResolver.

How did E4del RAT infiltrate my computer?

E4del RAT is delivered through phishing emails carrying malicious LNK shortcut files, usually inside ZIP archives. Opening the shortcut silently connects to an attacker-controlled FTP server and reads the commands stored in the server's greeting banner.

Those commands point to a second FTP server, which in turn triggers a PowerShell script. The script downloads a ZIP archive containing the genuine Discord files plus the attackers' replaced code, extracts it, and starts the program with the victim's username passed as a hidden argument.

SOCRadar researchers note that abusing FTP banners in this way could easily be adapted to ClickFix-style pages, where victims are tricked into pasting a command themselves. Threats of this kind also spread through fake download sites, pirated software, malvertising, and drive-by downloads.

How to avoid installation of malware?

Be careful with unexpected emails and the files attached to them. Do not open shortcut files or archives sent by unknown senders, and avoid clicking links in unsolicited messages. Keep Windows and your installed programs updated, since patches close the holes malware relies on.

Download software only from official developer websites or verified stores, and stay away from pirated content, cracks, and key generators. Use a trustworthy antivirus and scan the system regularly. 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.
