This has historically been a pretty fun challenge to do. Earlier levels are quite easy, but later levels can be quite challenging and require specialized skills

This has historically been a pretty fun challenge to do. Earlier levels are quite easy, but later levels can be quite challenging and require specialized skills (e.g. reverse engineering, binary exploitation, cryptography). There’s a decent focus on “realism” which makes the challenge series more interesting than a typical CTF. If you’re eligible to participate I’d highly recommend checking it out. P.S. if you do well, the NSA sends you swag; I have a couple of very nice signed letters and NSA medals that look great in my office :)
