Systems and methods for protecting customer payment data against malware attacks on inline frame payment forms

Abstract

The disclosed computer-implemented method for protecting customer payment data against malware attacks on inline frame payment forms may include (i) detecting a payment form in a payment page on an online merchant website (e.g., by monitoring the website for a user entry of payment information during a customer transaction session or by analyzing, in hypertext markup language associated with an inline frame (iframe), a document object model (DOM)) to identify the payment form, (ii) identifying the iframe on the online merchant website, (iii) determining whether the iframe is associated with a trusted domain utilized for processing the payment information to complete the customer transaction session, and (iv) performing a security action that protects against a potential malware attack by preventing completion of the customer transaction upon determining that the iframe is unassociated with the trusted domain. Various other methods, systems, and computer-readable media are also disclosed.
