This paper targets to the lag of code protection technology for Mach-O executable file on iOS. Consideration of code tamper, code injection on iOS, this paper has proposed a code protection scheme MFP(Mach-O File Protector) featuring with both encryption function and anti-debugging function based on UPX(the Ultimate Packer for eXecutables). Compared with UPX, MFP encrypt Mach-O executable file through 3DES and insert anti-debugging code to disable mainstream debugging software.
