Write a bash script that creates a simple Trojan Horse. The Trojan Horse should start a shell that always grants you access as the root user. Assume the following scenario: You as an attacker drop a script called Is (The Trojan Horse) into /tmp. When the legitimate root user executes Is in /tmp, a hidden shell with root access should be created in /tmp. The hidden shell provides you as an attacker always root access to the system. This attack assumes that the root user has in his PATH the ".", in the first place of the PATH or at least before the correct "Is" PATH. For test purposes you can also just execute "./Is" as the root user in /tmp. Write a bash script that creates a simple Trojan Horse.
