Devices, systems, and methods are disclosed. An agent resides in a mobile communication device. The agent detects Proximity-based Mobile Malware Propagation. The agent injects one or more trigger network connections in the candidate connection list. These connections appear as legitimate networks and devices, but instead trigger connection to an agent server on a service provider's network. By attempting to connect through the trigger network connection, the malware reveals itself. The system helps collect the malware signature within a short period of time after the malware outbreak in local areas, though such attacks typically bypass network based security inspection in the network.
