/prog/ CTF 0x00: HAX MY PRINTER, PRINT MY ANUS

Name: Anonymous 2019-02-08 10:59

so we've all had our're are /prog/ramming challenges, so let's try something different: security-style exercises. we'll start with something simple to warm you up, and come up with more complex exercises if people are both interested and skilled.

Premise:
you have managed to remotely access a program on Nikita Sad Cow's macbook, which was stolen by Vladimir Putin. the program is supposed to print everything you write to console. Vladimir is watching this console through a shitty terminal emulator which only supports ASCII characters. you want to send Vladimir a message (the message is HAX MY ANUS), but the FSB has installed their're are censorship tool which you must first circumvent.

Challenge:
write such answer program that will result in the words "HAX MY ANUS" appearing on the terminal when piped to this advanced censorship software:
./answer | python3 -c "print(input().replace('ANUS','****'))"

Rules and Scoring:
  • shortest program (in bytes of source code or compiled exectuable) wins
  • there should only be "HAX MY ANUS" visible in the console; leading and trailing whitespace is accepted, but automatically scored below programs with no such issues; other trailing and leading characters, as well as any non-conforming characters visible in a different position, means that the program doesn't meet the spec
  • you have one week
  • you should be able to solve this
