Are dating apps safe? be it a lifelong relationship or perhaps a stand that is one-night

Our company is accustomed entrusting dating apps with your secrets that are innermost. Exactly just How carefully do they view this information?

Looking for one’s destiny online — be it a one-night stand — has been pretty typical for a long time. Dating apps are now actually section of our day to day life. To obtain the partner that is ideal users of these apps are quite ready to expose their title, career, workplace, where they prefer to go out, and substantially more besides. Dating apps in many cases are aware of things of an extremely intimate nature, such as the periodic photo that is nude. But just exactly exactly how very very very carefully do these apps handle such information? Kaspersky Lab chose to place them through their safety paces.

Our specialists learned the most used mobile dating that is online (Tinder, Bumble, OkCupid, Badoo, Mamba, Zoosk, Happn, WeChat, Paktor), and identified the primary threats for users. We informed the designers ahead of time about all of the weaknesses detected, and also by enough time this text was launched some had been fixed, as well as others had been slated for modification into the forseeable future. Nevertheless, don’t assume all designer promised to patch every one of the flaws.

Threat 1. who you really are?

Our researchers found that four of this nine apps they investigated allow prospective crooks to find out who’s hiding behind a nickname according to information given by users by themselves. As an example, Tinder, Happn, and Bumble let anybody view a user’s specified destination of work or research. Making use of this information, it is feasible to get their social networking records and see their names that are real. Happn, in specific, utilizes Facebook is the reason information change utilizing the host. With just minimal work, everyone can find the names out and surnames of Happn users as well as other information from their Facebook pages.

And in case somebody intercepts traffic from a device that is personal Paktor installed, they may be surprised to discover that they are able to start to see the email addresses of other application users.

Ends up you can recognize Happn and Paktor users various other social media marketing 100% of times, by having a 60% rate of success for Tinder and 50% for Bumble.

Threat 2. Where are you currently?

If somebody desires to know your whereabouts, six associated with the nine apps will assist. Only OkCupid, Bumble, and Badoo keep user location information under lock and key. All the other apps suggest the exact distance you’re interested in between you and the person. By getting around and signing data in regards to the distance amongst the both of you, it is simple to figure out the location that is exact of “prey.”

Happn not only shows just how numerous meters split up you against another individual, but additionally how many times your paths have actually intersected, which makes it also more straightforward to monitor somebody down. That’s really the app’s primary function, since unbelievable as we think it is.

Threat 3. Unprotected data transfer

Many apps transfer information into the host over A ssl-encrypted channel, but you can find exceptions.

As our scientists learned, the most insecure apps in this respect is Mamba. The analytics module found in the Android os version will not encrypt information concerning the device (model, serial quantity, etc.), and also the iOS variation links to your host over HTTP and transfers all information unencrypted (and therefore unprotected), communications included. Such information is not just viewable, but additionally modifiable. For instance, it is easy for a party that is third change “How’s it going?” right into a demand for cash.

Mamba just isn’t the sole software that lets you manage someone else’s account regarding the straight straight back of a connection that is insecure. Therefore does Zoosk. Nevertheless, our scientists could actually intercept Zoosk information just whenever uploading brand new pictures or videos — and following our notification, the designers immediately fixed the situation.

Tinder, Paktor, Bumble for Android os, and Badoo for iOS also upload photos via HTTP, makes it possible for an assailant to locate down which profiles their prospective target is searching.

While using the Android os variations of Paktor, Badoo, and Zoosk, other details — for instance, GPS data and device information — can result in the hands that are wrong.

Threat 4. Man-in-the-middle (MITM) attack

Almost all internet dating app servers use the HTTPS protocol, meaning that, by checking certification authenticity, you can shield against MITM assaults, when the victim’s traffic passes via a rogue host on its way to the bona fide one. The scientists installed a fake certification to learn in the event that apps would always check its authenticity; they were in effect facilitating spying on other people’s traffic if they didn’t.

It ended up that many apps (five away from nine) are at risk of MITM assaults as they do not validate the authenticity of certificates. And the vast majority of the apps authorize through Facebook, so that the shortage of certificate verification can cause the theft of this authorization that is temporary by means of a token. Tokens are legitimate for 2–3 days, throughout which time crooks get access to a number of the victim’s social media account information as well as complete usage of their profile from the app that is dating.

Threat 5. Superuser liberties

Whatever the precise form of information the software shops from the unit, such information could be accessed with superuser liberties. This issues just Android-based devices; spyware in a position to gain root access in iOS is just a rarity.

Caused by the analysis is not as much as encouraging: Eight regarding the nine applications for Android os are prepared to offer information that is too much cybercriminals with superuser access legal rights. As a result, the scientists had the ability to get authorization tokens for social networking from the vast majority of the apps under consideration. The qualifications had been encrypted, however the decryption key ended up being easily extractable through the software it self.

Tinder, Bumble, OkCupid, Badoo, Happn, and Paktor all shop messaging history and photos of users as well as their tokens. Hence, the owner of superuser access privileges can quickly access confidential information.


The analysis indicated that numerous dating apps do perhaps perhaps not handle users’ delicate information with enough care. That’s no explanation to not ever make use of services that are such you just need to comprehend the problems and, where feasible, reduce the potential risks.
