I know that it's theoretically possible that a router can be hacked, and malware can be spread throughout a network merely by being connected to it.
However, I'm wondering what exactly the chances of this is, since, we never really hear about it often.
For example, universities share connections with hundreds of students, and not to be stereotypical, they are likely downloading all sorts of content that isn't deemed safe (verifying, torrenting etc).
So, let's say an infected device was connected to my home network. What's the chances of that particular device infected my network, and therefore infecting other devices on the network?
Here are my thoughts;
attacker would first need to compromise the router
attacker, if successful in compromising the router, would then need to know a zero-day attack to infect other devices
that's the only way they would be able to right? ignoring DNS poisoning.
