# Level08 Using ghidra, we can decompile the code and see that it does a backup of a file that we passed as a parameter (roughly). However, there are a few protections. First, the program `open()` our argument file (here, we want `/home/users/level09/.pass`. Since the binary has the permission for user `level09`, we can `open()` this file. The string `"./backups"` is concatenated to the filepath we pass as a parameter. It will then `open(..., OCREAT ...)` the file that we passed in `av[1]` and write the contents of the original file to this newly created file. However, since the path will have `"./backups"` at the beginning and we want to get the content of `/home/users/level09/.pass`, we need to recreate this file tree in the `/tmp` directory. Here is the process: ``` level08@OverRide:/tmp$ mkdir -p backups/home/users/level09 level08@OverRide:/tmp$ ~/level08 /home/users/level09/.pass level08@OverRide:/tmp$ cat backups/home/users/level09/.pass fjAwpJNs2vvkFLRebEvAQ2hFZ4uQBWfHRsP62d8S ```
