What thirty targets with similar security as chip fabs do you have in mind? I have a hard time coming up with anything other than nuclear plants for massive damage, but they have somewhat stricter access control, I hope. Oil pipelines are much quicker to repair and most countries have strategic reserves. Refineries maybe?

Liquified natural gas depots. Igniting one of these or a full LNG ship in the river or bay near population centers would kill tens of thousands and the fire could not be extinguished, we would have to let it run its course. Nuclear plants have a bit more security than a chip plant and the logistics of damage by nuclear plant takeover kind of require the authorities to do nothing for a long time.

What about critical infrastructure? Dams which could flood big areas are one example which would be absolutely destructive

I don't think flooding one area is on the same level as killing a large part of microchip production for a couple of years. Almost everything has a chip inside these days.
