Level10
Use the level10 password “interesting to hack” to access the level10 account and check the hint.
Since there is no information on the attack target file in the hint, I used the find command to search for the existence of the file with level11 privilege.
but, the file is not founded. Also, there is a directory called program in the home directory of level10, but it can not be checked because it is owned by root.
I checked the rc.local file because there might be a setting in the file that registers the program to start automatically when the system starts.
I can see that there is a program named level10. I tried the ps command to see if it is a running process.
Since there are no running process named level10, This program is a simple process, not a daemon type. A daemon is a process that runs repeatedly, and a simple process is a process that runs only once.The shared memory in the hint is used in the following way:
When I write the code using the conditions in question, I can write as follows.
When I compile the file and run it, I can get the level11 password as follows.
