Ideas for puzzles ================= * Bootable image with FreeDOS, Linux, Inferno? HURD? * Bury puzzles in various weird locations within each OS * Maybe put some in the boot loader, too * Perhaps have some sort of network puzzle as well * Network treasure hunt * DHCP option * Single TCP RST with token in payload * Multiple TCP RST with different payloads * http://10.0.0.2/token * PXE boot some sort of points-gathering client * Init asks for a team hash, and starts awarding points * Broken startup scripts, when fixed award more points * Lots of remote exploits * "qemu -net socket" vpn thingy and then... * sfxrar packed with upx. Change an instruction so it won't actually execute. * pwnables: have scp log passwords somewhere Capture the Packet ------------------ * Jim Meilander could teach a class about Bro * Use qemu -net socket,connect=10.0.0.2:5399 for capture the packet
