Concerning covert communications=2C I have a short story to tell:
Several years ago=2C I used to play World of Warcraft. The Game allows for =
LUA scripting=2C and the developers added some limitations as to prevent bo=
t scripting. One of the limitations was that you could not export data from=
or import into the game (file load and save LUA functions were present=2C =
but have been disabled by Blizzard).
To circumvent this limitation (I have some history of doing things deemed "=
impossible" by others...)=2C I did two things:
First=2C I wrote a LUA script that placed a field of 1024 dots on the scree=
n. The script accepted a string of up to 128 chars and encoded it in binary=
. It would then set the dots on the screen according to the bits=2C white f=
or 1 and black for 0. Finally=2C it would trigger a screenshot.
The second part of the exercise was a small VB.NET program that watched the=
screenshot folder for new files. If a new screenshot was detected=2C it lo=
aded the file and tried to find the dot-field within the new screenshot. If=
found=2C it would decode the binary - et voila: Data exported from the Gam=
e into an external program.
Greetings
