text: In exploiting this port type confusion vulnerability, the exploit authors were able to change the mach port type from IKOT_NAMED_ENTRY to a more privileged port type like IKOT_HOST_SECURITY allowing them to forge their own sec_token and audit_token, and IKOT_HOST_PRIV enabling them to spoof messages to kuncd.  After gaining root, the downloaded payload is loaded and run in the background on the victim's machine via launchtl.
