What type of attack exploits flaws in browsers and browser plugins?

1. Man-in-the-Browser

2. Man-in-the-Middle

3. Man-in-the-Connection

4. Man-in-the-Know

The correct answer is: Man-in-the-Browser

The attack that specifically exploits flaws in browsers and browser plugins is known as a Man-in-the-Browser attack. This type of attack involves malicious software (often referred to as a Trojan) that is able to intercept and manipulate transactions between a user and a web application. By injecting itself into the web browser, this malware can alter the contents of the web pages that users are viewing or the data that users submit, all without the user's knowledge. The significance of a Man-in-the-Browser attack lies in its ability to operate discreetly within the user's browsing session, effectively allowing the attacker to modify information such as banking credentials, payment amounts, or other sensitive data before it reaches the intended web server. This type of attack capitalizes on vulnerabilities present in the browser environment itself, making it particularly dangerous since it targets widely-used software that users may not always keep up to date. On the other hand, attacks categorized under other terms such as Man-in-the-Middle involve intercepting and relaying communications between two parties, but do not specifically target browser vulnerabilities. Similarly, terms like Man-in-the-Connection or Man-in-the-Know are not recognized types of attacks in the context of cybersecurity. Therefore, the Man-in-the-Browser attack is the most accurate
