If the challenge expects CTF..., we wrap it:
CTFc00lgui_top_xor_1s_4w3s0me!
Testing in the GUI — success: “You got it!”
From the .rdata section, find enc_data:

No discussion of the c00lgui top is complete without acknowledging its controversial origins. C00lgui was originally released on underground forums like UnknownCheats and Guided Hacking. While the creator (known only as "c00l") intended it as a programming showcase, the UI kit was quickly weaponized.
However, from a design perspective, the c00lgui top remains a masterpiece of information density. It fits: the c00lgui top
...into just 48 vertical pixels. That’s an efficiency most SaaS dashboards fail to achieve.
First, check the file type:
file c00lgui_top.exe
Output:
PE32 executable (GUI) Intel 80386, for MS Windows If the challenge expects CTF
Run strings to look for hints:
strings c00lgui_top.exe | grep -i flag
No direct flag, but we see interesting strings:
This suggests the flag is stored encrypted and compared after an XOR operation. Testing in the GUI — success: “You got it
