Removing Gomorrah stealer malware from the operating system

What is Gomorrah?

Gomorrah is an information-stealing malware. We obtained a sample from VirusTotal and subsequently analyzed this malicious program. We discovered that it primarily targets account credentials and credit card numbers.

Gomorrah malware overview

Gomorrah stealer begins its operations by gathering data about the following - operating system, processor, memory (RAM), device name, and anti-virus/security software.

This malicious program can extract information (mainly passwords) from these browsers: Google Chrome, Mozilla Firefox, Opera, Amigo, Brave, Comodo, Kometa, Orbitum, Torch, and Yandex. It can also extract this data from other applications - Mozilla Thunderbird (email client), FileZilla (FTP - File Transfer Protocol client), Pidgin (IM - Instant Messaging client), and Proxifier (proxy server support).

Gomorrah attempts to obtain cryptocurrency wallet credentials and credit card details. This program can download various files from the desktop and documents folder, e.g., databases (MySQL, SQLite, SQL server backups, and Microsoft Access), documents/ text files (.txt, .doc, docx, .xlsx, and .pdf), images (.jpg, .png, .gif, and .jpge), and log files (.log). Another one of Gomorrah's abilities is taking screenshots.

With such information in their possession, cyber criminals may be able to make unauthorized transactions or online purchases. Stolen accounts can be used to ask contacts for loads or to proliferate malware under the guise of the genuine owner (e.g., emails, social networking, social media, messengers, etc.).

To summarize, Gomorrah stealer malware infections can result in severe privacy issues, significant financial losses, and identity theft.

Malware in general

We have analyzed thousands of malware samples. Granda Misha, Mercurial grabber, and Grakate are a few examples of malicious programs with data-stealing functionalities.

Generally, malicious software can have various abilities in different combinations. Common types/functions are: loaders (chain infections), stealers (file/data extraction), spyware (keyloggers, desktop recording, ability to record audio/video via microphones and webcams, etc.), clippers (clipboard data replacers), ransomware (data encryption/ screen-locking for ransom purposes), cryptominers (system resource abuse to mine cryptocurrency), and so on.

How did Gomorrah infiltrate my computer?

At the time of research, we found that Gomorrah's developers were offering it for sale online. Hence, how this stealer is distributed depends on the cyber criminals using it.

In general, malware is usually spread using phishing and social engineering techniques. For example, spam emails can contain infectious files as attachments or download links. These files can be Microsoft Office and PDF documents, archives, executables, JavaScript, etc. When they are opened - the infection chain is initiated.

Malware is also proliferated via untrustworthy download sources, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc. Illegal activation tools ("cracks") can cause infections rather than activate licensed programs. Fake updaters infect systems by exploiting outdated software weaknesses and/or by installing malware.

How to avoid installation of malware?

We advise always downloading from official and verified channels. Another recommendation is activating and updating programs with tools/functions provided by genuine developers. The attachments and links present in suspicious emails - must not be opened/clicked, as they can contain malware.

We must stress the importance of having a reputable anti-virus installed and kept updated. This software must be used to perform regular system scans and to remove threats and issues. 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.
