well thank you for not leeching all I care
Ring0 is kernel kernel is considered lowest Ring0 is hell since you can kill ANY process as well protect yours and do what you want . Maybe there are lower versions but with Ring3 you still can make it impossible to remove just harder. His Ring3 is easy not to hard but yea
Theres lower than 0, just not many people know that, ring -1 is the hypervisor and ring -2 is system management mode, I made a post recently with a link to a vid on youtube from blackhat 2015 that showed a method on putting a rootkit into ring -2, where at that point, you would need new hardware to get rid of it, it's quite interesting actually, long video though, close to an hour
