![]() In addition, Google removed the app once ESET reported the findings. In Android 11 and up, the OS can place an app into a hibernation state, shutting down its functionalities if the user hasn’t interacted with the software in a few months.ĮSET added: “Besides this one case, we have not detected AhRat anywhere else in the wild.” Fortunately, Google has a safeguard that could’ve prevented the app from harming users. IRecorder - Screen Recorder attracted over 50,000 installs on Google Play. However, ESET has not uncovered evidence supporting either theory. It’s also possible the developer sought to secretly deliver the malicious update from the get-go. It’s possible the app came from a legitimate developer who had their account hijacked by a hacker. Why the app was secretly Trojanized remains unclear. “During our analysis, AhRat received commands to exfiltrate files with extensions representing web pages, images, audio, video, and document files, and file formats used for compressing multiple files,” ESET added. Hence, the malicious update wouldn’t have triggered any special permission requests on an Android phone because the user had already granted them in order to use the app’s existing screen-recording capabilities. “Notably, the malicious app provided video-recording functionality, so it was expected to ask for permission to record audio and store it on the device.” “These functionalities appeared to fit within the already defined app permissions model, which grants access to files on the device and permits recording of audio,” Stefanko said. But in August, the malicious update, which ESET dubs “AhRat,” introduced the ability for the app to steal files from a user’s smartphone and secretly record audio. The app was designed to help users record the screen on an Android phone and edit those screen captures. “It is rare for a developer to upload a legitimate app, wait almost a year, and then update it with malicious code,” wrote ESET researcher Lukas Stefanko.
