Since routers are hubs that directly handle household Internet traffic, they are exciting to attackers. They are ideally suited to be a vulnerability that gives you access to devices for a DDoS-style attack that overloads the target server with requests and shuts it down. However, the most important reason routers are becoming increasingly vulnerable is that they are much easier to hack than other devices. As web and mobile applications' overall state of security improves, router vulnerabilities are becoming an increasingly important target.
