#More info: http://www.xsec.org/index.php?module=Releases&act=view&type=1&id=6
#Written by Preddy
#
#don't create the poc png file on windows it won't work as it should
#when i create it on windows with activeperl or visual c
#the png header becomes: 89 50 4e 47 0d 0d
#instead of            : 89 50 4e 47 0d 0a
#
#I currently have no single idea WHY it does that...
#so use linux to compile/run the script or the program
