AntiJOP

AntiJOP is an anti-malware solution that recodes assembly language to remove JOP attack gadgets. JOP attacks on x86 often hinge on the availability of 0xFF bytes in preexisting code, which can be co-opted to serve as register-indirect call instructions. AntiJOP removes instances of 0xFF bytes that may exist, for example, in immediate values, MOD/RM bytes, etc.
