📚 Multiple Vulnerabilities In AirDroid Opens At Least 10 Million Android Users To MITM Attacks, Hijackings

AirDroid is a popular Android application that allows users to send and receive text messages and transfer files and see notifications from their computer. Zimperium, a mobile security company, recently released details of several major security vulnerabilities in the application, allowing attackers on the same network to access user information and execute code on a user's device. Since there are between 10 and 50 million installations of the app, many users may be imperiled by AirDroid. Android Police reports: The security issues are mainly due to AirDroid using the same HTTP request to authorize the device and send usage statistics. The request is encrypted, but uses a hardcoded key in the AirDroid application (so essentially, everyone using AirDroid has the same key). Attackers on the same network an intercept the authentication request (commonly known as a Man-in-the-middle attack) using the key extracted from any AirDroid APK to retrieve private account information. This includes the email address and password associated with the AirDroid account. Attackers using a transparent proxy can intercept the network request AirDroid sends to check for add-on updates, and inject any APK they want. AirDroid would then notify the user of an add-on update, then download the malicious APK and ask the user to accept the installation. Zimperium notified AirDroid of these security flaws on May 24, and a few days later, AirDroid acknowledged the problem. Zimperium continued to follow up until AirDroid informed them of the upcoming 4.0 release, which was made available last month. Zimperium later discovered that version 4.0 still had all these same issues, and finally went public with the security vulnerabilities today.
