 Codenamed as TURMOIL, the sensors operate as a sort of high-tech surveillance dragnet, monitoring packets of data as they are sent across the Internet.When TURBINE implants exfiltrate data from infected computer systems, the TURMOIL sensors automatically identify the data and return it to the NSA for analysis.And when targets are communicating, the TURMOIL system can be used to send alerts or "tips" to TURBINE, enabling the initiation of a malware attack.
