ISPs can send any firmware to a docsis cablemodem, without the user knowing or accepting. Imagine the damage that could be done by a malicious actor via the ISPs computers. Or imagine someone being able to hack the system that does that update even without the ISP. 600K users would be a toy, they could do it to 6 Million. Doesn't even have to be clever, just brick millions of cablemodems. North Korea or some other government level entity could manage the resources to figure that out.
