    An attack that encrypts guests would, theoretically, need to pick them off one by one.

    An attack that encrypts guests would be an enabler and be able to pick them off one by one ....... and that elevates everything onto altogether much higher levels of pain and gain, for that and those heaven sent and hell bent on exercise with fire and brimstone, madness and mayhem, conflict and CHAOS, hear not your fears and your screams ..... in much the same way as you do not heed their calls for a fundamental systems change and radical global overhaul to deal with all current expanding and exploding problems/inequitable unsatisfactory solutions.

    If they get to the platform

    If the attacker can compromise the platform underlying the hypervisor (which after all is just code, typically running over an OS), VMs are just system images stored as files somewhere on a drive. You don't necessarily have to attack the running instance of a VM.

      You're dealing with Core Kernel Shenanigans ........ which some may tell you are ramping up ACTive IT to Massive Mega MetaData Scale and which do play by any known rules. And such does create an IMPossible Problem with Zero Obvious Solution ..... with Convenient Answers to Present in/from the Future ‽ .

    Don't forget not everyone follows best practices - I've seen hypervisor management, storage and a very large number of desktops/laptops, all on the same flat network, with direct internet access.

    Maybe someone breached the VM/Hypervisor boundary, but it's likely to be something more basic.
