Description: "Abstract: 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.

Hello reader. I am writing this paper for two reasons. The first reason is to provide
some documentation on the Mach side of Mac OS X for people who are unfamiliar
with this and interested in looking into it. The second reason is to document my own
research, as I am fairly inexperienced with Mach programming. Because of this
fact, this paper may contain errors. If this is the case, please email me at
nemo@felinemenace.org and I will try to correct it."
