MiTB Attack Prevention

Man in the browser protection for online customers


Increasing MiTB security and Reducing Debug Time

A man-in-the-browser (MITB) attack is a type of cyber attack where an attacker is able to intercept and modify the communication between a user’s browser and a web application. The attacker uses malware to infect the user’s browser, which allows them to manipulate the data being sent and received by the browser, such as web page content, form data, or authentication credentials.


The attacker infects the user’s browser with malware, often through social engineering tactics or by exploiting vulnerabilities in the browser or operating system.

Communication interception

Once the browser is infected, the attacker can intercept and manipulate the communication between the browser and the web application, allowing them to steal data or modify transactions.

Data manipulation

The attacker can modify the web page content to deceive the user or manipulate form data to perform unauthorized actions within the web application, such as transferring funds or changing user settings.
