The expert gave advice on allowing messengers access to geolocation

Users should not give messengers access to their location, but the app will not function properly without permission to use the camera and microphone. This was stated by cybersecurity expert Alexey Rayevsky, speaking about the ability of applications to monitor the user.

Therefore, if you do not give such permissions to the messenger, then, most likely, it will not work normally. It's up to each user to choose whether to give access or not," Rayevsky said in an interview with aif.ru .
