Misconfigurations in a number of Android apps leaked delicate information of greater than 100 million customers, doubtlessly making them a profitable goal for malicious actors.
“By not following best-practices when configuring and integrating third-party cloud-services into purposes, tens of millions of customers’ personal information was uncovered,” Test Level researchers stated in an evaluation revealed at present and shared with The Hacker Information.
“In some instances, any such misuse solely impacts the customers, nevertheless, the builders had been additionally left susceptible. The misconfigurations put customers’ private information and developer’s inside assets, resembling entry to replace mechanisms, storage, and extra in danger.”
The findings come from a research of 23 Android purposes out there within the official Google Play Retailer, a few of which have downloads starting from 10,000 to 10 million, resembling Astro Guru, iFax, Brand Maker, Display Recorder, and T’Leva.

By not securing the database behind authentication limitations, the researchers stated they had been capable of acquire information belonging to customers of Angolan taxi app T’Leva, together with messages exchanged between drivers and passengers in addition to riders’ full names, cellphone numbers and vacation spot and pick-up places.
What’s extra, the researchers discovered that app builders embedded keys required for sending push notifications and accessing cloud storage companies straight into the apps. This might not solely make it simpler for unhealthy actors to ship a rogue notification to all customers on behalf of the developer, however may be exploited even to direct unsuspecting customers to a phishing web page, thus turning into an entry level for extra subtle threats.
Embedding cloud storage entry keys into the apps, likewise, opens the door to different assaults whereby an adversary may pay money for all information saved within the cloud — a habits that was noticed in two apps, Display Recorder and iFax, thereby giving the researchers the power to entry display recordings and faxed paperwork.
Test Level notes that just a few of the apps modified their configuration in response to accountable disclosure, implying customers of different apps proceed to stay vulnerable to attainable threats like fraud and id theft, to not point out leverage the stolen passwords to realize entry to different accounts fraudulently.
“In the end, victims turn out to be susceptible to many various assault vectors, resembling impersonations, establish theft, phishing and repair swipes,” stated Aviran Hazum, Test Level’s supervisor of cell analysis, including the research “sheds gentle on a disturbing actuality the place utility builders place not solely their information, however their personal customers’ information in danger.”
