| A better question is, “why do you think your local network is safe?”. Have you taken steps to validate the integrity of every single device connected to the network? If a single device is compromised, how will detect its been compromised? If a device is compromised, what prevents it from being used to launch an attack on other devices in your network, especially if your security model assumes that all devices on your local network are “safe”? For a practical example of this happening, in a very impressive manner: https://arstechnica.com/security/2024/11/spies-hack-wi-fi-ne... For a more boring everyday equivalent, just search around for one of the many botnets that are assembled from compromised SoHo routers, or IoT devices, around the world. https://arstechnica.com/security/2024/01/chinese-malware-rem... Assuming a local network is safe and secure is foolish. There’s nothing inherently secure about a local network, the only reason it offers any level of security is due to a local network being many-many orders of magnitude smaller than the entire internet. So the probability of a hostile device (whether intentional installed as hostile, or became hostile after a remote attack) being connected is smaller. But at the end of the day, is security via “being luckier than the next dude”. |
