As an IT manager who has been in the field for nearly 30 years I can see this coming. There is an irrational push to place data, some confidential, in the hands of strangers out in the "cloud". Microsoft365 and Microsoft's "on-premise" price modeling compels businesses to use web based applications. If they can manufacture this preventive "cyber covid" hysteria (making people mortally terrified over a less than half a percent threat) to the degree to inject an unknown substance with little concern then I have little doubt they can pull this off by telling people or implementing the attack themselves.
This is do-able.

Buy metals, food, ammo.
