Getting silly now, the problem is if someone has a private unpublished exploit or has found a hole then they will struggle to patch it, they obviously dont have much experience with these things as the fix pattern is obvious.
Hack 1) must have been vanilla, update vanilla and restore from backup
Hack 2) must have left a back door on first hack, reinstall all of LET and restore from backup
Hack 3) must have found an entry point via LEB reinstall everything.
Which probably means if hack 4 happens they will be all out of ideas, I don't really want to see the place die it's just business now after all any community spirit was ripped out by chief.
