Avoid installation of Agent Tesla via the Mundinter malspam campaign

Also Known As: Mundinter malspam campaign
Type: Trojan
Damage level: Severe

What is Mundinter email virus?

In most cases, cyber criminals behind malspam campaigns disguise their messages as official and important, and sent from legitimate companies and organizations. Their main goal is to trick recipients into opening a malicious file attached to the email (or that can be downloaded through a link in the email) - the file installs malicious software.

This malspam campaign is disguised as a message from a Portuguese health and beauty shop called Mundinter and is sent to proliferate Agent Tesla, a Remote Access Trojan (RAT).

Mundinter Email Virus malware-spreading email spam campaign

Cyber criminals behind this malspam campaign send emails disguised as messages regarding an "Urgent Enquiry". The messages have the "Urgent Enquiry_002.img" file (its name may vary in different variants of this malspam campaign) attached.

This image file contains a malicious executable file named "Urgent Enquiry_002.exe" (its name may also vary), which, if executed, installs Agent Tesla. This RAT has capabilities of a keystroke logger - it can record keyboard input.

Therefore, cyber criminals can use Agent Tesla to steal login credentials (usernames, email addresses, passwords), credit card details and other sensitive information. They could sell stolen information to other cyber criminals, steal personal accounts, identities, make fraudulent purchases and transactions, and/or misuse it for other malicious purposes.

New variants of Agent Tesla are now targeting Wi-Fi credentials as well - they can be used to steal Wi-Fi profiles and their passwords to spread this malware on other devices via an identical wireless network.

Therefore, executing the malicious file attached to this email can result in serious problems (such as monetary loss, identity theft, loss of access to personal accounts, etc.).

More examples of similar malspam campaigns are "Swedish Energy Agency Email Virus", "INPS Email Virus" and "COELECSA Email Virus". Most are are disguised as official messages from legitimate companies/organizations and sent to trick recipients into opening a malicious file designed to infect systems with malware.

Examples of malicious programs that cyber criminals spread in this way are Ursnif, HawkEye and TrickBot.

How did "Mundinter Email Virus" infect my computer?

In this particular case, Agent Tesla RAT is installed on the operating system only if recipients mount the attached IMG file and execute the malicious file, which is stored within it. Malware distributed via malspam campaigns cannot be installed on computers unless users execute downloaded malicious files.

Cyber criminals commonly also attach other files to distribute malware via email. For example, malicious Microsoft Office, PDF documents, executable files (.exe), archive files such as ZIP, RAR, and JavaScript files.

Note that malicious MS Office documents infect systems only when users enable content/editing (macros commands), however, documents opened with MS Office versions released before 2010, infect computers without having to gain any permission (these versions do not include "Protected View" mode).

How to avoid installation of malware?

Files or website links in received emails that are irrelevant, sent from unknown, suspicious addresses should not be opened. Software should be downloaded from official websites and via direct download links.

All other sources such as unofficial pages, third party downloaders, Peer-to-Peer networks (e.g., torrent clients, eMule), freeware download pages can be used to distribute malicious files/software. Furthermore, it is important to update and activate installed software with tools or implemented functions that are provided by the official developers.

Third party updating, activation tools are often designed to install malware. Unofficial activation tools also activate licensed software illegally. Use reputable antivirus or anti-spyware software to scan the computer for threats (this should be performed regularly).

Keep this software up to date. If you have already opened a "Mundinter Email Virus" attachment, 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:

manual malware removal step 4In 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.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check 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".

locate the malware file you want to remove

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.

searching for malware file on your computer

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.
