Buffer Overflow Attack on Windows

Generally Exploiting In windows system is very tough,though you have to overcome various protection and bypass.In some cases you have to use Kernel Mode exploits.
And also we will show you the target machine which we will perform attack is XP,otherwise if we will try on win7,win8,win10,then we will have to cross the path where all doors are closed.hope you got my point.First we will discuss some of the protection mechanism here. ASLR
DEP
SEH
SAFESEH
SEHOP
Control Flow Guard(CFG) Stack Compiler Option(/GS cookie option) EMET Heap Isolation and many more coming.............
