Claims that Mac OS X 10.10 still allows serious kernel abuse: a method to load unsigned kext without warnings (no kextutil patching), a host_priv escalation to grant nonroot users kernel module install rights, and direct kernel memory access techniques used to unlink kernel objects and hide processes; demos run on Yosemite and successfully hide a calculator process. Delivered code includes an exploit kit and rootkit XPRC, a detector SVV-X rootkit and scanner, and a user-mode checker SVV-X-U, all tested and working.
