23 Android Apps Expose Over 100,000,000 Users’ Personal Data

Misconfigurations in numerous Android apps leaked delicate details of extra than 100 million users, likely earning them a profitable goal for malicious actors.

“By not subsequent ideal-practices when configuring and integrating 3rd-get together cloud-expert services into applications, hundreds of thousands of users’ private information was exposed,” Verify Position researchers claimed in an evaluation revealed these days and shared with The Hacker Information.

“In some conditions, this sort of misuse only impacts the consumers, nonetheless, the developers have been also left vulnerable. The misconfigurations set users’ personalized info and developer’s internal sources, this sort of as entry to update mechanisms, storage, and far more at danger.”

The conclusions occur from a research of 23 Android purposes available in the formal Google Engage in Retailer, some of which have downloads ranging from 10,000 to 10 million, this kind of as Astro Expert, iFax, Symbol Maker, Display screen Recorder, and T’Leva.

In accordance to Test Issue, the issues stem from misconfiguring genuine-time databases, drive notification, and cloud storage keys, resulting in spillage of e-mail, mobile phone figures, chat messages, spot, passwords, backups, browser histories, and pictures.


By not securing the databases driving authentication obstacles, the researchers stated they were in a position to attain data belonging to end users of Angolan taxi application T’Leva, including messages exchanged in between drivers and travellers as properly as riders’ total names, cellphone numbers and destination and choose-up locations.

What’s a lot more, the researchers identified that app builders embedded keys expected for sending thrust notifications and accessing cloud storage solutions straight into the applications. This could not only make it less difficult for terrible actors to send out a rogue notification to all end users on behalf of the developer, but could also be exploited even to immediate unsuspecting users to a phishing website page, so getting to be an entry level for more complex threats.


Embedding cloud storage obtain keys into the applications, similarly, opens the door to other attacks wherein an adversary could get hold of all information stored in the cloud — a conduct that was noticed in two applications, Monitor Recorder and iFax, thereby supplying the scientists the means to access screen recordings and faxed documents.

Test Place notes that only a several of the applications improved their configuration in response to dependable disclosure, implying consumers of other applications keep on to stay vulnerable to possible threats like fraud and identification theft, not to point out leverage the stolen passwords to acquire obtain to other accounts fraudulently.


“Finally, victims grow to be vulnerable to several various attack vectors, this kind of as impersonations, determine theft, phishing and company swipes,” reported Aviran Hazum, Check Point’s supervisor of mobile study, incorporating the analyze “sheds light on a disturbing actuality wherever application builders location not only their details, but their personal users’ knowledge at threat.”
