Halloween. A gory and ghastly night of ghouls, ghosts, and goblins. And as with previous years marking All Souls, I reflect on the latest digital demons molesting the oil and gas industry, how best to exorcise them, and how to speedily return them to the land of the undead.

When you open the front door to this season’s mob of treat-hunting ghouls, just remember that your work world is not only facing its own cyber spooks at the gate. There’s a better than even chance that you have more than one zombie system staggering around, AI Apparitions secretly messing up your performance system, and a cloud vampire sharpening its fangs.

Good luck.
