Scrambled Message

Text

A spy has been transmitting classified information from our agency to the enemy, we need to find out what information was transmitted. Unfortunately, the spy has scrambled his communications. Luckily, we could dump the memory of his 32 bit little endian based computer.

You get three files, scrambled_message.rkt contains a bit of code to get you started, message.bin contains the captured message the spy has been transmitting, and memory.bin contains the memory dump.

We think that the memory dump contains the positions of the characters of the classified information in the message, find out if this is the case and recover the leaked information.

Files

  • message.bin
  • memory.bin
  • scrambled_message.rkt

How To Solve

See scrambled_message_solution.rkt. Solution is not there!
