Solution

I tried to use Ghidra for this challenge, but without a success. So, I’ve decided to take another approach (didn’t want to waste time for investigation what’s wrong with Ghidra).

With Hexedit I’ve found plaintext flag parts in the binary.

The parts were:

• SHELL{
• 5hR1n3}
• M3L0v4l3
• nT_

Combined together gave the flag.

Flag

SHELL{M3L0v4l3nT_5hR1n3}
