It takes a team to do security right, so we have layered our defenses!

Steps

After downloading Layered_security I executed file layered_security and observed the file is GIMP XCF image data. Next, I launched gimp layered_security to open the file in GIMP. Initially, I see a photo with multiple layers.

Starting at the top layer, I removed each layer one at a time until getting to Pasted Layer $3 where I found the flag.
