Abstract

A method for preventing transmission of malicious data may include receiving transaction data including at least one packet associated with a payment transaction; extracting at least one of network layer data or transport layer data from a header of the at least one packet; determining a first probability indicating that the at least one packet is in a first class based on the at least one of the network layer data or the transport layer data using a classifier. The method may also include determining a second probability indicating that the at least one packet is in a second class based on the at least one of the network layer data or the transport layer data using the classifier; and blocking the at least one packet. A system and a computer program product are also disclosed.
