AT commands, originally designed in the early 80s for controlling modems, are still in use in most modern smartphones to support telephony functions. The role of AT commands in these devices has vastly expanded through vendor-specific customizations, yet the extent of their functionality is unclear and poorly documented. In this work, we systematically retrieved and extracted 3,500 AT commands from over 2,000 Android smartphone firmware images across 11 vendors. We methodically tested our corpus of AT comma
To spur further research into AT commands, we are releasing a web interface to the database of AT commands discovered. For more details on the process of extracting the commands, view the paper. If you are interested in some of the code used during this project, check out our Github. Finally, to see a demonstration of an AT command controlling a phone, view the video.
