Abstract: A method for data packet communication between a data beacon and a command-and-control server that are located within separate networks can comprise accessing a beacon identification indicator. The method can also comprise generating a command-request data packet comprising the beacon identification indicator and a public network address associated with the data beacon. Additionally, the method can comprise transmitting the command-request data packet to a command-and-control server address. The method can also comprise receiving a command data packet from the command-and-control server that comprises a command to query a local database for specific data elements. The method can then include querying the local database for the specific data elements. Further, the method can include generating a response data packet that comprises the specific data elements. Further still, the method can include transmitting the response data packet to the command-and-control server address.
