Tackling another Lets Defend Challenge, that being the FREE EASY DIFFICULTY "Android Infostealer" challenge. We are given an apk file to analyze to answer 13 questions. "A user downloads what appears to be a legitimate mobile app from an app store. The app seems to work fine and doesn't raise any suspicion, but in the background, it silently installs an Android info stealer malware on the user's device. The malware is designed to collect a wide range of sensitive information from the device, including call logs, SMS messages, contacts, browsing history, and location data. It may also be able to take screenshots, record audio or video, and access the device's camera. Try to reverse it and help this user with information."
