In a highly secure online banking environment, customers report unauthorized access to their accounts despite...

According to the CEH System Hacking and Web Application Security modules, Man-in-the-Browser (MitB) attacks are among the most sophisticated and difficult session-hijacking techniques to detect. In MitB attacks, malware operates inside the victim’s browser, allowing attackers to intercept, modify, or inject transactions after authentication has occurred.

CEH documentation highlights that MitB attacks bypass:

Multi-factor authentication

Encrypted cookies

HTTPS/TLS protections

Because the malicious activity occurs at the browser level, security controls perceive transactions as legitimate.

Option B is correct.

Option A (XSS) is detectable via content security policies.

Option C is mitigated by regenerating session IDs.

Option D is ineffective against encrypted sessions.

CEH emphasizes MitB attacks as a critical threat to online banking systems.
