Patent

CA 2714549

An Off-Line MMS Malware Scanning System and Method that detects malware in MMS messages without delaying Multimedia Messaging Service (MMS) Communications is presented The system comprises a network traffic scanner that replicates MMS traffic, with the original MMS traffic passing unaffected directly to the receiving mobile device, and a copy of the MMS traffic being routed to a packet reassembler that reconstructs the original MMS message. The reconstructed MMS message is then scanned, and if malware is detected, the receiving mobile device is notified of the presence of malware in the received MMS message. Because the MMS messages are scanned off-line, the flow of MMS traffic to mobile devices is not delayed.

L'invention concerne un système et un procédé de balayage de maliciel MMS hors ligne qui détectent un maliciel dans des messages MMS sans différer des communications de messages multimédia (MMS). Le système comprend un balayeur de trafic de réseau qui reproduit le trafic MMS, le trafic MMS d'origine passant directement vers le dispositif mobile de réception sans être affecté et une copie du trafic MMS étant acheminée vers un dispositif de réassemblage de paquets qui reconstruit le message MMS d'origine. Le message MMS reconstruit est ensuite balayé et, si un maliciel est détecté, le dispositif mobile de réception est averti de la présence du maliciel dans le message MMS reçu. Etant donné que les messages MMS sont balayés hors ligne, le flux de trafic MMS vers les dispositifs mobiles n'est pas différé.
