site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com The xnu kernel is written in C with little bits of C++ here and there (like the open bits of IO kit). You shouldn't have to worry about any ObjC code. re: the EFI, I think you definition of 'kernel' may be a bit skewed. Also, back doors tend to be things written in the higher-level software that make up an OS, and not in the kernel (like a master-password that the login app always responds to, etc.). Or possibly things like crypto libraries that always embed a second copy of the key in the key-bag which can be decrypted by a private key that the government has, etc. You can narrow the scope of your search by focusing on any utility that needs be run as uid 0 and the standard crypto libraries (although with Darwin that's OpenSSH which is quite well peer-reviewed).

hi all, do the Darwin kernel has backdoors to any "spy network"? specially interested in backdoors to any .gov's.

not on the mood of solo'ing an audit of ObjC code; specially that there are no decent (or accessible, or known) ObjC references.

if there's EFi, enSUI doesn't require a (traditional) kernel.
