PLEASE CAREFULLY NOTE what we are and are not explicitly stating about this potential for a remotely exploitable vulnerability: Take control of the network that was previously protected by that router. GRC's DNS test evolves into a full blown exploit that allows a remote hacker to Armed with the knowledge of the existence of such a possible vulnerability, skilled hackers - and make no mistake about it, these people are highly skilled - are often able to refine the characteristics of the “crashing packet” to cause the affected system to execute code they provide in a some sophisticated version of that packet.Īnd, with that, the minor annoyance that once crashed a router when running This is typically evidence of a previously unknown “buffer overrun” or “unchecked buffer” vulnerability in the affected device. The development of virtually all successful remote Internet exploits begins when someone notices that something unexpectedly crashes a system. What this means is that the Internet data packets entering these routers from the outside are, in some way, something that the router does not currently handle properly - so the router crashes.
