Message from Happn in intercepted traffic

Remember that a lot of associated with the programs inside our research usage authorization via Twitter. This implies the user’s password is protected, though a token that enables authorization that is temporary the application may be taken.

Token in a Tinder application demand

A token is a vital useful for authorization that is given by the verification solution (within our instance Facebook) during the demand of this individual. It’s released for a time that is limited frequently 2 to 3 months, and after that the application must request access once again. Making use of the token, this program gets most of the necessary information for authentication and certainly will authenticate the consumer on its servers by simply confirming the credibility associated with token.

Illustration of authorization via Facebook

It’s interesting that Mamba sends a generated password to the e-mail target after enrollment utilizing the Facebook account. The password that is same then employed for authorization from the host. Therefore, into the application, you’ll intercept a token and on occasion even a password and login pairing, meaning an attacker can get on the software.

App files (Android)

We chose to always check what type of application information is saved from the unit. Even though information is protected because of the operational system, along with other applications don’t get access to it, it could be acquired with superuser rights (root). Because there are not any extensive harmful programs for iOS that may get superuser liberties, we think that for Apple unit owners this risk isn’t appropriate. Therefore just Android os applications had been considered in this area of the research.

Superuser rights are not too uncommon with regards to Android os products. According to KSN, into the quarter that is second of these were set up on smart phones by significantly more than 5% of users. In addition, some Trojans can gain root access on their own, using weaknesses when you look at the operating-system. Studies regarding the option of information that is personal in mobile apps had been performed a few years ago and, even as we can easily see, little changed ever since then.

Analysis showed that a lot of applications that are dating perhaps maybe not prepared for such assaults; if you take benefit of superuser legal rights, we been able to get authorization tokens (primarily from Facebook) from practically all the apps. Authorization via Twitter, once the user does not need certainly to show up with brand new logins and passwords, is an excellent strategy that boosts the safety of this account, but as long as the Facebook account is protected with a strong password. Nonetheless, the application token itself is generally maybe maybe not saved firmly sufficient.

Utilizing the facebook that is generated, you will get short-term authorization when you look at the dating application, gaining complete use of the account. When you look at the instance of Mamba, we even was able to obtain a password and login – they may be effortlessly decrypted utilizing an integral stored into the software it self.

The majority of the apps inside our study (Tinder, Bumble, okay Cupid, Badoo, Happn and Paktor) store the message history into the exact same folder as the token. As being result, when the attacker has acquired superuser liberties, they have use of communication.

In addition, virtually all the apps store photos of other users into the memory that is smartphone’s. It is because apps utilize standard ways to available website pages: the machine caches pictures that may be exposed. With use of the cache folder, you’ll find away which profiles the consumer has seen.


Having collected together all of the weaknesses based in the studied relationship apps, we obtain the table that is following

App venue Stalking HTTP (Android os) HTTP (iOS) HTTPS communications Token
Tinder + 60% minimal Low + + +
Bumble 50% Low NO + + Cupid that is OK% NO NO + + +
Badoo 0% Medium NO + +
Mamba + 0% tall High + +
Zoosk + 0% High High – (+ iOS) +
Happn + 100% NO NO + + +
WeChat + 0% NO NO
Paktor + 100% e-mails Medium NO + + +

Location — determining individual location (“+” – feasible, “-” not possible)

Stalking — finding the complete name associated with the individual, along with their records various other internet sites, the portion of detected users (portion suggests how many successful identifications)

HTTP — the capability to intercept any information through the application submitted a form that is unencrypted“NO” – could maybe maybe perhaps not discover the information, “Low” – non-dangerous information, “Medium” – data which can be dangerous, “High” – intercepted data which senior match com can be used to obtain account management).

HTTPS — interception of information sent within the encrypted connection (“+” – possible, “-” extremely hard).

Messages access that is user communications simply by using root legal rights (“+” – possible, “-” impossible).

TOKEN — possibility to take verification token simply by using root legal rights (“+” – feasible, “-” extremely hard).

Some apps practically do not protect users’ personal information as you can see from the table. Nevertheless, general, things might be even even worse, despite having the proviso that in training we didn’t research too closely the alternative of finding certain users of this solutions. Needless to say, our company is maybe not likely to discourage folks from making use of dating apps, but we wish to provide some tips about simple tips to utilize them more properly. First, our advice that is universal is avoid general general public Wi-Fi access points, specially the ones that aren’t protected by way of a password, work with a VPN, and install a safety solution in your smartphone that will detect spyware. They are all really appropriate when it comes to situation in question and assistance avoid the theft of information that is personal. Secondly, try not to specify your home of work, or just about any other information which could determine you. Safe dating!
