Abusing Mach on Mac OS X
This paper discusses the security implications of Mach being integrated with the Mac OS X kernel. A few examples are used to illustrate how Mach support can be used to bypass some of the BSD security features, such as securelevel. Furthermore, examples are given that show how Mach functions can be used to supplement the limited ptrace functionality included in Mac OS X.
