Hey look it's us! |
For the uninitiated, a CTF (capture-the-flag) is a hacking competition where there are certain puzzles in any form, be it an image, or a virtual disk, or an executable or what-say-you, and the idea is to recover some flag cleverly hidden inside of it. The topics this time around were:
Binary: digging through executable files
Cryptography: encoded files
Forensics: partially-damaged or unaccessible files
Grab Bag: anything/everything
Networking: ..networking
Web: ..web
Flags were in the format MCA-{8 digits of hex}
Writeups of a few:
Binary 100
Binary 200 #1
Binary 200 #2
Cryptography 100
Cryptography 200
Networking 200
