Looking for one’s future on line — be it a lifelong relationship or a one-night stay — has been fairly common for quite a while. To discover the best mate, customers of these apps will be ready to display their name, job, workplace, where that they like to hang out, and much more besides. Relationships software tend to be privy to items of an extremely intimate characteristics, such as the occasional topless picture. But how thoroughly do these applications handle this type of facts? Kaspersky Lab decided to place them through her safety paces.

Our professionals analyzed the most popular mobile online dating sites programs (Tinder, Bumble, OkCupid, Badoo, Mamba, Zoosk, Happn, WeChat, Paktor), and recognized the main risks for consumers. We well informed the designers in advance about most of the vulnerabilities recognized, and by enough time this book premiered some had recently been repaired, among others are slated for modification in the future. But its not all designer promised to patch every one of the defects.

Hazard 1. Who you are?

Our experts unearthed that four on the nine apps they investigated allow potential criminals to find out who’s covering up behind a nickname predicated on data given by people themselves. As an example, Tinder, Happn, and Bumble allowed people see a user’s given workplace or learn. Utilizing this records, it’s feasible to get their social networking accounts and see their unique genuine labels. Happn, particularly, utilizes fb accounts for facts trade making use of machine. With just minimal energy, anyone can figure out the names and surnames of Happn consumers and various other tips using their Twitter profiles.

And if people intercepts site visitors from your own product with Paktor setup, they might be surprised to find out that capable look at e-mail addresses of other application customers.

Ends up you can easily determine Happn and Paktor customers in other social media 100% of times, with a 60% rate of success for Tinder and 50percent for Bumble.

Threat 2. In which could you be?

When someone desires discover your whereabouts, six regarding the nine software will help. Best OkCupid, Bumble, and Badoo hold individual place information under lock and secret. The many other software indicate the length between you and the person you’re enthusiastic about. By getting around and signing facts towards range within couple, it’s easy to figure out the exact location of the “prey.”

Happn not merely shows how many yards separate you against another consumer, but also the number of hours their paths need intersected, making it less difficult to track people down. That’s really the app’s major feature, as incredible as we find it.

Threat 3. exposed data exchange

The majority of apps convert facts towards server over an SSL-encrypted channel, but you will find exclusions.

As our very own scientists realized, one of the more insecure applications within admiration are Mamba. The statistics component utilized in the Android os type does not encrypt data concerning device (model, serial wide variety, etc.), and the apple’s ios adaptation links toward host over HTTP and exchanges all data unencrypted (and thus exposed), messages included. These information is not simply readable, but in addition modifiable. For example, it’s easy for an authorized to change “How’s it supposed?” into a request for the money.

Mamba isn’t the just application that allows you to control some body else’s account about again of a vulnerable connection. Thus does Zoosk. But all of our experts were able to intercept Zoosk facts only when posting newer photos or clips — and following the notice, the designers immediately set the difficulty.

Tinder, Paktor, Bumble for Android os, and Badoo for iOS additionally upload photos via HTTP, allowing an attacker to discover which profiles her possible sufferer is browsing.

With all the Android variations of Paktor, Badoo, and Zoosk, more facts — for instance, GPS information and equipment resources — can result in the incorrect fingers.

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

Just about all internet dating app machines utilize the HTTPS process, meaning that, by checking certification credibility, one can possibly protect against MITM problems, when the victim’s site visitors passes through a rogue host on its way into the genuine one. The experts set up a fake certification to learn in the event the apps would see its authenticity; as long as they performedn’t, they were in effect facilitating spying on other people’s site visitors.

It ended up that a lot of applications (five regarding nine) is vulnerable to MITM assaults as they do not validate the credibility of certificates. And most of the software authorize through myspace, so the decreased certificate confirmation can lead to the theft from the short-term consent input the form of a token. Tokens are valid for 2–3 days, throughout which time burglars have access to many of the victim’s social networking fund facts besides full access to her profile from the online dating app.

Threat 5. Superuser liberties

Regardless of precise form of data the application shops in the device, these facts tends to be reached with superuser legal rights. This problems merely Android-based units; malware able to obtain root access in iOS try a rarity.

The result of the research try around stimulating: Eight of this nine solutions for Android os will be ready to give an excessive amount of details to cybercriminals with superuser accessibility liberties. As such, the researchers had the ability to bring authorization tokens for social media from almost all of the apps at issue. The qualifications comprise encoded, although decryption trick is conveniently extractable from the application by itself.

Tinder, Bumble, OkCupid, Badoo, Happn, and Paktor all shop messaging records and photos of people and their unique tokens. Therefore, the holder of superuser accessibility privileges can access confidential ideas.


The study showed that lots of online dating apps try not to handle customers’ painful and sensitive facts with sufficient care. That’s no reason not to need these providers — you just need to comprehend the difficulties and, in which possible, minimize the risks.
