Questions & Answers

Q: What is a man-in-the-browser attack?

A man-in-the-browser attack occurs when an adversary installs malware on a victim's computer, intercepts the victim's web browsing, and manipulates transactions between the victim and the bank.

Q: Why are one-time passwords and transaction authentication important in preventing fraud?

One-time passwords and transaction authentication ensure that the legitimate customer's intended transaction is carried out, even if there is interference from malware. It adds an extra layer of security by linking the password to the specific transaction.

The Payment Services Directive is a European law that mandates more secure transaction authentication. While it lacks technical details, it ensures a minimum level of security across European countries.
