Include dating software safer? Matchmaking apps are now part of our everyday lifestyle.

We’re familiar with entrusting internet dating apps with this innermost ways. How very carefully would they view this information?

Oct 25, 2017

Seeking one’s destiny online — be it a lifelong relationship or a one-night stand — has been rather typical for quite some time. To find the best companion, customers of these apps will be ready to unveil their particular term, job, workplace, where they like to hold down, and much more besides. Matchmaking applications are often aware of points of a rather intimate character, such as the unexpected topless photo. But exactly how carefully create these software handle these facts? Kaspersky laboratory decided to put them through their unique safety paces.

Our very own gurus learned the most used cellular online dating sites software (Tinder, Bumble, OkCupid, Badoo, Mamba, Zoosk, Happn, WeChat, Paktor), and recognized the key dangers for users. We well informed the builders ahead of time about every weaknesses found, by enough time this text was launched some have recently been set, and others happened to be slated for modification in the future. But its not all designer guaranteed to patch the faults.

Hazard 1. Who you are?

All of our experts unearthed that four from the nine applications they examined allow prospective attackers to figure out who’s hiding behind a nickname considering information offered by users on their own. Including, Tinder, Happn, and Bumble leave any individual see a user’s given office or study. Making use of this facts, it’s feasible to track down their own social networking account and discover their real brands. Happn, particularly, makes use of fb is the reason information exchange utilizing the host. With minimal efforts, everyone can learn the labels and surnames of Happn people as well as other info from their Twitter users.

While some one intercepts site visitors from your own equipment with Paktor put in, they could be shocked to discover that they are able to start to see the e-mail details of various other app people.

Looks like you can diagnose Happn and Paktor consumers various other social networking 100% of that time, with a 60% rate of success for Tinder and 50per cent for Bumble.

Threat 2. In which have you been?

When someone really wants to learn your whereabouts, six on the nine apps will assist. Best OkCupid, Bumble, and Badoo keep user location facts under lock and trick. All of the other software suggest the exact distance between you and anyone you’re contemplating. By active and signing facts concerning the length involving the both of you, it’s an easy task to figure out the precise precise location of the “prey.”

Happn besides shows the amount of meters split up you against another consumer, but also the quantity of circumstances their routes have actually intersected, rendering it even easier to track someone lower. That’s actually the app’s primary feature, as incredible as we think it is.

Threat 3. exposed facts transfer

The majority of apps transfer data on host over an SSL-encrypted station, but you’ll find exclusions.

As our very own professionals revealed, very vulnerable applications within this admiration was Mamba. The statistics component utilized in the Android variation doesn’t encrypt information towards unit (unit, serial amounts, etc.), as well as the apple’s ios adaptation connects to your host over HTTP and transfers all information unencrypted (and so unprotected), messages provided. These types of information is not just readable, and modifiable. Including, it is easy for a third party to alter “How’s they supposed?” into a request for money.

Mamba is not the sole application that enables you to handle some one else’s membership in the straight back of an insecure link. Therefore do Zoosk. However, our professionals were able to intercept Zoosk data only once posting latest images or video — and after all of our notification, the developers promptly solved the situation.

Tinder, Paktor, Bumble for Android os, and Badoo for iOS furthermore upload photo via HTTP, allowing an opponent discover which profiles their particular prospective victim is actually searching.

While using the Android versions of Paktor, Badoo, and Zoosk, additional info — as an example, GPS information and product info — can end in unsuitable fingers.

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

Most online dating application machines make use of the HTTPS method, which means, by checking certificate authenticity, you can guard against MITM problems, where victim’s traffic goes through a rogue machine coming with the bona fide one. The scientists installed a fake certification to discover when the applications would search the authenticity; should they didn’t, they were essentially assisting spying on other people’s site visitors.

They turned out that most programs (five regarding nine) were susceptible to MITM assaults as they do not confirm the credibility of certificates. And most of the applications approve through myspace, therefore the insufficient certificate verification may cause the theft regarding the short-term consent key in the form of a token. Tokens include valid for 2–3 days, throughout which opportunity criminals get access to some of the victim’s social media marketing fund facts and full access to their particular visibility on matchmaking application.

Threat 5. Superuser rights

Whatever the exact style of data the app shop about device, this type of facts can be reached with superuser rights. This problems just Android-based devices; malware in a position to gain underlying accessibility in apple’s ios try a rarity.

The consequence of the analysis was under encouraging: Eight with the nine solutions for Android os are prepared to provide continuously suggestions to cybercriminals with superuser accessibility legal rights. Therefore, the experts managed to get agreement tokens for social media from almost all of the programs under consideration. The credentials were encoded, however the decryption trick was conveniently extractable from application by itself.

Tinder, Bumble, OkCupid, Badoo, Happn, and Paktor all shop chatting history and pictures of users combined with their particular tokens. Hence, the holder of superuser access rights can simply access private ideas.


The study revealed that numerous matchmaking applications you should never handle users’ delicate information with sufficient treatment. That’s no reason at all to not make use of this type of service — you merely need to comprehend the issues and, in which feasible, reduce the potential risks.
