forgotten-message

I made a cool program to show the flag, but i forgot to output it! Now that I lost the source, I can’t seem to remember the flag. Can you help me find it?

Solution:

1. Static Analysis

Since the executable is not stripped, where we can analyze the debugging symbols which has the possibility of containing the flag string

2. Use $strings and $grep

We can utilize grep with the flag header “LITCTF” and get the flag.

Flag: LITCTF{y0u_found_Me_3932cc3}
