Abstract
A computer system programmed to provide improved packet capture comprises: a plurality of sensor computers each programmed to capture data packets directed to a different compromised computer; a command server that is programmed to determine an expiration time for capturing a first set of data packets that have been routed toward a first compromised computer, to determine a time interval indicating an interval for capturing the first set of data packets, to identify a first packet capture filter of a plurality of packet capture filters for a first sensor computer of the plurality of sensor computers, to transmit, via a communications network, the first packet capture filter and a message, which comprises the time interval and the expiration time, to the first sensor computer of the plurality of sensor computers to capture the first set of data packets every the time interval and until the expiration time expires.
