Method and system for identifying malicious messages in mobile communication networks, related network and computer program product therefor

Abstract

A system for identifying malicious messages transmitted over a mobile communication network includes: sentinel modules associated with respective mobile terminals in the network for monitoring messages passing therethrough, wherein the sentinel modules identify as a candidate malicious message, any message passing through the mobile terminals and failing to comply with a first set of patterns and issue a corresponding sentinel identification message; a set of probe modules for monitoring messages transmitted over the network, wherein the probe modules identify as a candidate malicious message any message transmitted over the network and failing to comply with a second set of patterns and issue a corresponding probe identification message; and preferably at least one client honeypot module for receiving and processing any messages sent thereto to produce corresponding processing results, wherein the client honeypot module identifies as a candidate malicious message any message producing a processing result failing to comply with a third set of patterns and issues a corresponding client honeypot identification message.
