Analysis Summary

Mekotio is a banking trojan that targets users in Latin America and Europe. It is primarily distributed via phishing emails and infected software installers. Once installed on a victim’s device, Mekotio can perform a variety of malicious actions, such as stealing login credentials for online banking accounts, keylogging, and taking screenshots. The malware is also capable of evading detection by antivirus software and can also use a variety of methods to maintain persistence on an infected system.

Mekotio is also known for its modular structure, which allows attackers to add new functionality to the malware as needed. The malware is typically sold on underground forums and is offered as a service, with the attackers charging a fee for the use of the malware and providing technical support to customers.

Additionally, Mekotio is a polymorphic malware, meaning that it can change its code structure each time it is executed, making it harder to detect by antivirus software. To protect against Mekotio and other banking trojans, it is important to use strong, unique passwords for all online accounts, avoid clicking on links in unsolicited emails, and keep all software up to date.
