Questions to ask IT

  • Do we run Apple Multiple Products, and which versions?
  • Is any of it reachable from the internet?
  • Have we checked whether it has already been used against us?
  • If it is still not patched, what mitigation is in place, and what is holding the fix up?

Next steps

  1. Confirm exposure, mitigation status and any service interruption risk.
