sud - a su daemon for corellium devices

Related tags



What is this?

sud is a simplistic su daemon for Corellium, and maybe other, Android devices. It is older Superuser code, slightly refactored and heavily stripped down to the pure basics. Simply put, it will allow anyone who requests for su to be granted it. This is not something you should run on your personal device, this is a huge security issue. However if you want to test things or allow anything to run with root privledges, this is for you. This binary could also be easily modified to log all incoming su requests for such things as simplistic "taint" trace or watching what binaries use it for.


Building should be rather simple, simply create a Makefile.local file to properly point to you compiled of choice (CC) and system root (SYSROOT). These are located inside your Android NDK (ANDROID_NDK) directory for most people. You can check the Makefile.local.sample in this repository as an example. Once this is done, simply run make.

Installing on Corellium Android Devices

Build the binaries in this repository following the directions in the Build section. Then on the local machines connect to the device via adb and push the following files;

adb push init.sud.rc /data/local/tmp/
adb push bin/su /data/local/tmp/

Then get a shell, via adb and run the following commands;

/system/bin/mount -orw,remount /system
/vendor/bin/cp /data/local/tmp/su /system/xbin/su
/vendor/bin/chown root /system/xbin/su
/system/bin/chcon u:object_r:su_exec:s0 /system/xbin/su
/vendor/bin/chmod 06755 /system/xbin/su

/vendor/bin/cp /data/local/tmp/init.sud.rc /system/etc/init/init.sud.rc
/vendor/bin/chown root /system/etc/init/init.sud.rc
/system/bin/chcon u:object_r:system_file:s0 /system/etc/init/init.sud.rc
/vendor/bin/chmod 644 /system/etc/init/init.sud.rc
