However, After calling this method on /usr/sbin/spindump I got NULL pointer (instead of valid string) and it matches the output from user-space command code sign : codesign -dvvv /usr/sbin/spindumpĬodeDirectory v=20100 size=3267 flags=0x0(none) hashes=95+5 location=embeddedĬandidateCDHash sha256=d5bfa6a2a2ad8ffa377c6ef7f7b94c81821821fbĬDHash=d5bfa6a2a2ad8ffa377c6ef7f7b94c81821821fbĪuthority=Apple Code Signing Certification AuthorityĪs you can see, the TeamIdentifier is not set.

Printf("signing name = %s", Name) įollowing pmdj advice below, I've found a way to extract the signature of a running process using csproc_get_blob and csproc_get_teamid to extract the specific field which may represent the vendor (there are also synonyms for vnode instead of process). print organization name e.g: "Apple Inc." NSArray *certificates = molChecker.certificates In user-space I've found good API for this called MOLCodesignChecker which is activated in the following way MOLCodesignChecker *molChecker = initWithBinaryPath:filePath error:&error] Looking in xnu source code, I've found out mac_vnode_check_signature in mac_framework.h However it's not part of kernel public api. 20:31:33.I'm using kauth kernel framework in order to get events on files that are being opened in the system.Īfter filtering out the executable macho files, I'd like to check the signature validation for each such file that it's vnode is represented in vp = (vnode_t) arg1
