Noppenheimer​

At Defcon CTF Finals, the Final round of LiveCTF went into sudden death. The challenge was named Noppenheimer, a play on the Oppenheimer film that was released, and NOP (NO-OP) instructions.

Contestants had to turn a random sequence of bytes into a gadget/shellcode cave by converting bytes into NOPs, by sending "nuke" Launch commands.

Options:
LAUNCH x,y - Launch a test at position x,y
VIEW - See state of test site
ENDTEST - Conclude testing

Both teams solved locally. But they couldn't exploit Noppenheimer against the remote system.
