I see - I am sure those sort of attacks will happen. If you secure thousands of ETH in a single validator and are tied with something that could be shorted - such as a company and its stock or token - then your situation is just as vulnerable to attack as keeping your cold wallet in your home's safe. Somebody could break into your house and either coerce you to provide the staking keys, or crack the device, or find another vulnerability if your opsec is not effective enough. If you're staking in the cloud with Amazon you are probabbly even more vulnerable.
But isn't this the whole idea? By staking, you are placing your capital at risk in order to help secure the network. This is how staking is often described by Ethereum developers.
