Abstract
Devices, systems, and methods are disclosed which utilize lightweight agents on a mobile device to detect message-based attacks. In exemplary configurations, the lightweight agents are included as contacts on the mobile device addressed to an agent server on a network. A malware onboard the mobile device, intending to propagate, unknowingly addresses the lightweight agents, sending messages to the agent server. The agent server analyzes the messages received from the mobile device of the deployed lightweight agents. The agent server then generates attack signatures for the malware. Using malware propagation models, the system estimates how many active mobile devices are infected as well as the total number of infected mobile devices in the network. By understanding the malware propagation, the service provider can decide how to deploy a mitigation plan on crucial locations. In further configurations, the mechanism may be used to detect message and email attacks on other devices.
