Mekotio Trojan – Virus Infection Methods

The Mekotio Trojan is a versatile banking Trojan which is currently being used in a widespread campaign in Latin America. Several reports indicate that the countries which are most affected by it are Mexico, Brazil, Chile, Spain, Peru and Portugal.

It appears that the countries which are selected by the hackers are the Spanish and Portugese speaking ones in the Americas. What is known about it is that it has been actives since 2015 where the first major version of it was detected. This first version was written in the Delphi programming language which means that it is compatible with modern operating systems.

It is believed that most of the Trojan samples are distributed using SPAM methods. This is the bulk creation of fake content which are directed against the targets. There are two popular variants which are used for this purpose:

  • Email Messages — The hackers can construct email messages that look like as if they have been sent in by famous companies or services. Common variants are online merchants, social networks and even online banks.
  • Hacker-created sites — The criminals can construct fake pages of well-known portals. This is also done by prior infections with browser hijackers which will redirect the victims to a hacker-controlled page.

When the users access the dangerous contents they will end up with a virus executable or an archive file (usually ZIP). When they are run the infection sequence will be started.

As always the first stage is the payload dropper — it will download the relevant malicious packages from a remote server. They contain some of the base code and a second downloader which will be started and deliver the rest of the Mekotio Trojan. The third stage will deliver a PowerShell script which will download the main threat using a specified URL. The last four stage is the starting of the local malware.

Trojan horse infections like this one can alternatively be carried by other methods as well. They are often carried in other kinds of hacker-created files, the two most popular cases are the macro-infected documents: presentations, text files, databases and spreadsheets. When they are opened by the victims a prompt will be shown asking the users to enable the built-in code. If this is enabled the malware will be delivered and installed automatically. The other method is the insertion of the relevant code in setup bundles of well-known software. This includes popular application which are often installed by end users: creativity suites, productivity tools, system utilities and etc.

All virus related data can also be sent via file-sharing networks where users frequently distribute both legitimate and pirate content.

During the distribution the security experts uncovered that during the network communication the Trojan horse used custom values for the headers. This marks an unique signature which allows it to be easier to track the ongoing infections. However the transmission of command lines and instructions to the local agent is built in a way which safeguards against security analysis.

Mekotio Trojan – Virus Capabilities

When the Mekotio Trojan is installed on the local machine it will start a persistent connection to a hacker-controlled servers. They allow the criminals to spy on the victims, steal their files and run various types of actions.

Instead of a traditionl server the Mekotio Trojan hackers use a SQL Database server. This means that instead of the typical HTTP commands the remote connections will request and send out SQL commands which will translate to malicious actions. While this technique has been used before it ensures that active infections will be very difficult to trace.

There are several methods through which the addresses of the command and control servers are generated: based on a hardcoded list of “fake domains”, by using the current date and time and the day. This is particularly useful as it allows great flexibility when it comes to the control of the hacked computers. Other malicious actions which can be run include by the main engine include the following:

  • Windows Registry Editing — The Trojan can edit existing values in the Windows Registry and therefore impact the execution of installed services and functions. If the virus creates entries for itself then this may be used to launch an even deeper infection. Consequences for the users can include performance issues and data loss.
  • Boot Options Changes — Another malicious action which is often run by such viruses is the editing of the boot options. This will run the virus whenever the system is started. In other cases it can also block the access to the recovery boot options. This makes manual removal much more difficult.
  • Additional Virus Delivery — Trojan horses are typically used to install other viruses to the victim devices. Examples are file encrypting Trojans — they are used to process user data and the blackmail the victims for a ransomware payment. Alternatively the hackers can program in the installation of cryptocurrency miners which will download and run complex performance-intensive tasks. For each completed and reported task the hackers will earn money in cryptocurrency.
  • This Mekotio Trojan horse infection is rated as very dangerous. For this reason we recommend that actiev infections are removed as quickly as possible in order to prevent further damage to the computers.
