Over 4000 Android Apps Expose Users' Data via Misconfigured Firebase Databases

Over 4000 Android Apps Expose Users' Data via Misconfigured Firebase Databases
May 12, 2020
More than 4,000 Android apps that use Google's cloud-hosted Firebase databases are 'unknowingly' leaking sensitive information on their users, including their email addresses, usernames, passwords, phone numbers, full names, chat messages and location data. The investigation, led by Bob Diachenko from Security Discovery in partnership with Comparitech, is the result of an analysis of 15,735 Android apps, which comprise about 18 percent of all apps on Google Play store. "4.8 percent of mobile apps using Google Firebase to store user data are not properly secured, allowing anyone to access databases containing users' personal information, access tokens, and other data without a password or any other authentication," Comparitech said. Acquired by Google in 2014, Firebase is a popular mobile application development platform that offers a variety of tools to help third-party app developers build apps, securely store app data and files, fix issues, and ev

Skyrocketing data breaches bring incalculable losses to organizations and can cost cybersecurity executives their jobs. Here we examine the top five places in 2019 where cybercriminals are stealing corporate and government data without ever getting noticed and then learn how to avoid falling victim to unscrupulous attackers. 1. Misconfigured Cloud Storage 48% of all corporate data is stored in the cloud compared to 35% three years ago, according to a 2019 Global Cloud Security Study by cybersecurity company Thales that surveyed over 3,000 professionals across the globe. Contrastingly, only 32% of the organizations believe that protecting data in the cloud is their own responsibility, counting on cloud and IaaS providers to safeguard the data. Worse, 51% of the organizations do not use encryption or tokenization in the cloud. (ISC)² Cloud Security Report 2019 assets that 64% of cybersecurity professionals perceive data loss and leakage as the biggest risk associated with the

Thousands of Mobile Apps Expose Their Unprotected Firebase Hosted Databases
Jun 21, 2018
Mobile security researchers have discovered unprotected Firebase databases of thousands of iOS and Android mobile applications that are exposing over 100 million data records, including plain text passwords, user IDs, location, and in some cases, financial records such as banking and cryptocurrency transactions. Google's Firebase service is one of the most popular back-end development platforms for mobile and web applications that offers developers a cloud-based database, which stores data in JSON format and synced it in the real-time with all connected clients. Researchers from mobile security firm Appthority discovered that many app developers' fail to properly secure their back-end Firebase endpoints with firewalls and authentication, leaving hundreds of gigabytes of sensitive data of their customers publicly accessible to anyone. Since Firebase offers app developers an API server, as shown below, to access their databases hosted with the service, attackers can gain acce

Verizon FiOS app vulnerability Exposes 5 MILLION Customers' Email Addresses

Verizon FiOS app vulnerability Exposes 5 MILLION Customers' Email Addresses
Jan 19, 2015
A critical vulnerability discovered in Verizon 's FiOS mobile application allowed an attacker to access the email account of any Verizon customer with relative ease, leaving almost five million user accounts of Verizon's FiOS application at risk. The FiOS API flaw was discovered by XDA senior software developer Randy Westergren on January 14, 2015, when he found that it was possible to not only read the contents of other users' inboxes, but also send message on their behalf. The issue was discovered while analyzing traffic generated by the Android version of My FiOS , which is used for account management, email and scheduling video recordings. Westergren took time to put together a proof-of-concept showing serious cause for concern, and then reported it to Verizon. The telecom giant acknowledged the researcher of the notification the same day and issued a fix on Friday, just two days after the vulnerability was disclosed. That's precisely how it shou
