Check Point Research CPR recently analyzed several popular dating dating app radius with over 10 million downloads combined in order to understand how safe they are for users. As dating apps traditionally utilize geolocation data, offering the opportunity to connect with people nearby, this convenience feature often comes at a cost. CPR discovered that the Hornet app sends precise coordinates to the server. Nevertheless, they claim to protect user locations by randomizing the distance displayed in the application, making it, in their opinion, impossible to determine the exact location. However, this is not the case. At the time of our research, the measures taken by Hornet were insufficient to protect user coordinates, allowing for the determination of user locations with very high accuracy. Following the responsible disclosure process, we attempted to contact the Hornet team, providing them with the results of our research. Just before this publication, we reexamined the Hornet application. Since the specified responsible disclosure deadlines have passed, we are publishing the results of our research. This information can range from very precise location details such as a specific address or location coordinates derived through GPS Global Positioning System to less precise location data obtained via IP address, Wi-Fi, cellular networks, or Bluetooth beacons. Geolocation technology, while beneficial, presents several risks, especially when it comes to privacy and security within apps. These include potential privacy breaches from unauthorized data access, unintended sharing of location data with third-party entities, risks of tracking and surveillance, and security vulnerabilities like location spoofing. This information could be exploited by stalkers, burglars, or other malicious actors. In Hornet and similar applications, users in the search results are sorted in ascending order of distance. If we find two users in the search results who allow the display of their distance, and the target user is located between them in the search results, we can determine the approximate distance to the target user as an average value of two known distances:. Dating app radius 1 — Estimating the approximate distance to the user based on known distances to neighbors. However, the presence of users near the target is not a necessary condition. To determine the distance to the dating app radius, it is required to register an additional account, the coordinates of which can be controlled. You can determine the distance between two users by iteratively dividing the range in half and positioning an additional account at the midpoint. By analyzing the search results and refining the search based on the presence of the target user, progressively narrowing down the distance between the target and dating app radius additional account, we can achieve the desired precision. Figure 2 — Technique for determining the distance to the user using the positioning of an auxiliary account. We used two-step trilateration: first, we performed trilateration using two dating app radius points to obtain two possible candidate locations intersection points of the circles. Then, we used the distance information from the third reference point to select the correct solution. For example, this could be a small town. Around this area, we randomly generated 30 sets of reference points in a ring with an inner radius of 5 km and an outer radius of 10 km. As a result of trilateration for each group of reference points, we obtained a set of possible coordinates for the target point. Dating app radius maximum error in geolocation was meters, and the minimum was only 2 meters. We calculated the mean value of latitude and longitude for all points. The distance between the mean value and the target point appeared to be 24 meters. Being able to determine the approximate location, we generated reference points at a distance of 1 to 2 kilometers around the region where the target was supposed to be located. Applying our method, we obtained many estimates of the target location. The geolocation errors were distributed almost uniformly, with a minimum of 1. We also calculated the average latitude and longitude for the results. The resulting average point was less than 5 meters away from the target point:. Figure 3 — The final location estimate has an error of less than 5 meters. By repeating the experiment many times for different target points, we consistently obtained location accuracy within 10 meters. When it comes to dating applications, exposing user geolocation poses significant risks to privacy. Our experiments revealed potential vulnerabilities in the Hornet dating application, which has over 10 million downloads. The developed distance estimation methodology, combined with trilateration using a large number of reference points, demonstrated a very high accuracy in determining user locations. Hornet developers applied changes to mitigate the risks, reducing the location accuracy to 50 meters. This improvement, while significant, still allows a motivated attacker to determine approximate coordinates. CPR strongly advises users to be vigilant about the permissions they grant to apps and to stay informed about the potential risks and best practices for protecting privacy and security when dealing with geolocation data. By disabling location services, users can prevent apps from tracking their whereabouts and gathering information about their movements. This measure can effectively safeguard user privacy and thwart the sharing of personal data with external entities.
