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.
