Description

This module uses the su binary present on rooted devices to run a payload as root. A rooted Android device will contain a su binary (often linked with an application) that allows the user to run commands as root. This module will use the su binary to execute a command stager as root. The command stager will write a payload binary to a temporary directory, make it executable, execute it in the background, and finally delete the executable. On most devices the su binary will pop-up a prompt on the device asking the user for permission.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
