Methods and systems for detecting and preventing the spread of malware on instant messaging (IM) networks by analyzing message traffic patterns

摘要

Methods and systems for reducing the spread of malware in communication between an instant message (IM) client and an IM server are described. An IM filter module (IM FM) is configured to examine incoming messages from an IM server to an IM client and outgoing messages from the IM client to the IM server. The IM filter module is further configured to analyze relationship among the incoming and outgoing messages and determine whether one or more messages contain malware based on the analysis of relationship among the incoming and outgoing messages.
