Abstract
A technique allows associating host applications and user agents in network traffic and detecting possible malware without relying on signatures of the user agents. A database of host applications and user agents is maintained, allowing automatic update of the database when a new application or new application to user agent mapping is discovered. Partial matches may be made when a change is made to the application, allowing learning the new mapping automatically. If an application is associated with more than a threshold number of user agents, an indication may be generated that the application is suspicious and possibly malware.
