I'm back, I found bunny_helpers.sh in my trash (impossible to restore it) so, first i tried to paste it in the /root/udisk/payloads/extensions/ file but the commands
source bunny_helpers.sh
and obviously
GET $TARGET_IP #or any variables
didn't worked
so, second solution, i tried to put bunny_helper.sh (and the other files witch where in extensions) in /root/tools/ but it didn't worked either.
