+# Zombie
+> Oh, shoot, I could have sworn there was a flag here. Maybe it's still alive out there?
+
+## About the Challenge
+
+We given some machine and find the flag
+
+## How to Solve
+
+First we gonna look up the directory with `ls -la`
+
+And you will find some interesting script
+
+![solve1](images/solve1.png)
+
+From that script, we analyzed the flag is already deleted, but we can use `ps aux` to see the process of script
+
+![solve2](images/solve2.png)
+
+After that we can see the process in `/proc/` directory
+
+![solve3](images/solve3.png)
+
+Last we just can cat the flag with `cat /proc/PID/fd/numbers`

+
+## How to Solve
+
+To solve this, all you need is `stegsolve`
+
+You can download here [stegsolve](https://github.com/zardus/ctf-tools/blob/master/stegsolve/install)
+
+But before you open it to stegsolve, make sure already add the `.jpeg` extension
+
+After that `Analyse` > `File Format`, just slowly scroll down and you got flag
