Covert location surveillance devices are electronic devices hidden by an adversary to collect location data.
An adversary typically hides covert location surveillance devices in or on a target's usual means of transportation, such as a car or bike.
Covert location surveillance devices need a way to determine their own location. They do this:
- Most often using GPS.
- In some cases, using alternatives to GPS such as GLONASS or satellite phone services.
- In rare cases, by emitting radio waves that are received by a nearby surveillance operator (typically in a vehicle following the target's vehicle).
Collected location data can be used as evidence in court. Non-incriminating, mundane location data can reveal a lot about the targets of surveillance and help in network mapping.

Mitigations
| Name | Description |
|---|---|
| Bug search | You can conduct a bug search to locate covert location surveillance devices and eventually remove them. |
| Physical intrusion detection | An adversary often needs to covertly enter the space where a vehicle is parked to install a covert location surveillance device on the vehicle. You can use physical intrusion detection to detect such a covert entry. |
| Transportation by bike | You can use a bike instead of any other type of vehicle: unlike other vehicles, when you conduct a bug search of a bike you can determine with a high degree of confidence whether or not a covert location surveillance device is installed on the bike. You should store the bike indoors to make it harder for an adversary to install a covert location surveillance device on it. |

| Case against Boris | GPS tracking devices were placed under several vehicles after investigators learned that Boris — who did not have a driver license — was being transported in them[1]. In one case, investigators learned at 2:30 p.m. from an intercepted phone call that someone close to Boris was planning to borrow a vehicle and drive Boris to a party in the evening. They witnessed the vehicle being borrowed, followed it to the party, waited until it parked, and at 9:45 p.m. they had placed a tracking device on it. |
