Section 2.4.3 "Threat to Communication Links" expands on the state of vulnerabilities present for RPAs:
- Jamming of commercial satellite communications (SATCOM) links is a widely available technology. It can provide an effective tool for adversaries against data links or as a way for command and control (C2) denial.
- Operational needs may require the use of unencrypted data links to provide broadcast services to ground troops without security clearances. Eavesdropping on these links is a known exploit that is available to adversaries for extremely low cost.
- Spoofing or hijacking links can lead to damaging missions, or even to platform loss.
Section 2.4.4 "Threat to Position, Navigation, and Guidance":
- Small, simple GPS noise jammers can be easily constructed and employed by an unsophisticated adversary and would be effective over a limited RPA operating area.
- GPS repeaters are also available for corrupting navigation capabilities of RPAs.
- Cyber threats represent a major challenge for future RPA operations. Cyber attacks can affect both on-board and ground systems, and exploits may range from asymmetric CNO attacks to highly sophisticated electronic systems and software attacks.
UPDATE (1453 PST 14DEC11): I just confirmed with the Public Intelligence website that the Air Force document was provided to their site about one week ago which would make it the day after the news on the downed RQ-170 was announced. Clearly someone with FOUO access wanted this information to be made public to inform the controversy surrounding the incident.
