  • →In Safari/browser context, itms:// URLs are automatically passed to iTunes without user interaction, making drive-by exploitation possible; monitor browser-to-iTunes URL handler invocations. ↗
  • →SafeSEH bypass uses QuickTime.qts gadget at 0x67215e2a (ADD ESP,8; RETN); presence of this return address in memory or network payload is a strong exploit indicator. ↗
  • ·Only vfork-based payloads are reliable on OS X due to iTunes being multithreaded; standard fork/exec payloads may be unstable. ↗
  • ·The exploit payload space is limited to approximately 1024 bytes due to browser URL length constraints. ↗
