Which of the following attacks primarily targets financial transactions using a trojan?

• A. DNS footprinting
• B. Denial of Service
• C. Man-in-the-Browser
• D. Cross-Site Scripting

Answer: (C)

The attack that primarily targets financial transactions using a trojan is the Man-in-the-Browser. This type of attack involves malware infecting a user's web browser, inserting itself into the communication between the user and the web application without the user’s knowledge. When the trojan is installed, it can intercept information being sent to and from the browser, including sensitive financial transaction data. For instance, it can manipulate the transaction details, such as altering the recipient's account information during a funds transfer, allowing the attacker to redirect funds without the victim's awareness. This makes it particularly dangerous for online banking and e-commerce, as the user believes they are engaging in legitimate transactions when, in fact, they are being manipulated. In contrast, other attack methods such as DNS footprinting, Denial of Service, and Cross-Site Scripting, do not specifically target financial transactions in the same manner. DNS footprinting is primarily used for reconnaissance rather than direct financial manipulation, Denial of Service aims to make a service unavailable rather than to steal or alter financial data, and Cross-Site Scripting typically exploits a vulnerability in web pages to inject malicious scripts but does not necessarily involve financial transaction interception directly in the same way as a Man-in-the-Browser attack does
