Dating application users, you will no longer look at your phone the same way after discovering the work of two security experts. Colby Moore and Patrick Wardle, researcher at Synack, an independent security firm, took a close look at the behavior of these programs. They then discovered that it was possible to use certain manipulations to precisely determine the position of another user.

In this case, it is Grindr, whose particularity is to be intended for the homosexual community, which was the subject of the tests. The principle is simple: the application locates the user and offers profiles of people located nearby. Below each of them, information is given on the distance at which the other is.

By making three location requests from three different positions, anyone would be able to calculate the coordinates of a user, in short a simple triangulation. If Grindr is concerned, it is not the only application to work on this principle. The equivalent of Grindr also open to heterosexuals Tinder suffered from this same weakness, before a patch applied last year.

Finally, the only way to protect yourself permanently from the problem is to deactivate the location function, except that, as a rule, this simply prevents this kind of application from working. Between finding love or being found by a stalker, it is therefore better to choose your dating applications wisely.
