Glupteba virus removal guide
What is Glupteba?
Glupteba is a trojan-type program, malicious software that installs other programs of this type. Cyber criminals distribute Glupteba through malicious advertisements that can be injected into legitimate websites or advertising networks. Research shows that Glubteba can be used to distribute a browser stealer or router exploiter. In any case, this malware should be uninstalled immediately.
The installed browser stealer can be used to steal personal, sensitive details such as website cookies, browsing history and account logins, passwords from browsers such as Google Chrome, Opera and Yandex. In this way, the stealer can be used to gain access to various accounts that victims use through their browsers. Hacked accounts can be used to make fraudulent purchases, proliferate malicious programs and scam campaigns, or steal other sensitive information. Stolen cookies can be used to gain unauthorized access to various information (or services) in the system. Stolen browsing data could be misused by selling or sharing it with other parties. An example of how other parties exploit users' browsing histories is through targeted ad creation. In this case, users might start seeing various ads that were tailored according to stolen data. The installed router exploiter can be used to compromise the router and configure it to generate malicious traffic using stolen administrator credentials. An example is when compromised routers start receiving spam mail that might be designed to trick users into visiting untrustworthy or even malicious pages. To avoid problems relating to privacy, browsing safety, monetary loss, and other issues, we strongly recommend that you uninstall Glupteba from your system immediately.

|Malware Removal (Windows)||
To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
The internet is full of trojan-type programs. Other examples are Nymeria, Retefe, and Vigorf. Typically, these programs proliferate other malware such as information stealers, ransomware, banking malware, and so on. They can lead to serious damage. Therefore, if you believe that you computer is infected with malicious software, remove it immediately.

How to avoid installation of malware
To keep computers and operating systems safe, download, install, update software, and browse the web carefully. Do not download files or programs using third party downloaders (or install them using third party installers), Peer-to-Peer networks, or the other sources mentioned above. The safest way to download is via official websites. Update installed software using implemented functions or tools created by official software developers. Files that are attached to irrelevant emails and sent from unknown, suspicious addresses should not be opened. The same applies to web links. Installed programs should not be activated using third party ('cracking') tools - these are illegal and often lead to installation of malware. Scan the operating system for viruses using reputable anti-virus or anti-spyware software and remove detected threats immediately. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.
Update September 13, 2019 - Cyber criminals are continually updating this ransomware and implementing new, additional features. The most recent versions of Glupteba are written in the Go programming language, developed by Google. Additionally, the new variants are designed to misuse the EternalBlue exploit to infiltrate other computers connected to the same network. The list of additional features also includes bypassing of User Account Control (UAC) and gaining a high integrity level, as well as privileges. A noteworthy function of new Glupteba's variants is cryptocurrency mining. Malware employs system resources to mine cryptocurrency, which is received by cyber criminals (you can find more information regarding cryptominers in this article). The list of routers targeted by Glupteba now includes those manufactured by MikroTik.

Update August 12, 2020 - Cyber criminals have recently started distributing Glupteba trojan via fake YouTube video download website - video-youtube-get[.]ru. Instead of downloading an actual video, the website downloads a malicious executable which injects Glupteba into the system:
Update October 1, 2020 - There is a new Glupteba malware variant which is written in the open-sourced programming language called Go (Golang). It injects malicious code to the svchost.exe, a legitimate Windows process and makes this process the downloader of the payload. Research shows that one of the payloads of this new Glupteba variant includes installation of extensions for malicious ads. It is known that it can install that extension not only on Windows-based browsers, but also on Linux-based, Android-based, and even IOS-based web browsers. Also, Glupteba is capable of launch an EternalBlue exploit with a purpose to spread this dropper across the network.

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:
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 the "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 file 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 Malwarebytes for Windows.
