CTFlearn-Writeups/Forensics/Rubber Duck

Rubber Duck

The main idea finding the flag using easiest forensics techniques.

Step-1:

After we download RubberDuck.jpg, we try to open and see the flag and check if we find any.

Step-2:

I tried simple techniques and easily found answer when we send the command:

strings RubberDuck.jpg | grep {

Note: Although some general techniques also include strings RubberDuck.jpg | grep flag & strings RubberDuck.jpg | grep ctf.

Step-3:

We get the following output:
