Patch early, patch often
If you are using an ASUS router in the list below you should go to this page now to get the proper firmware update or unplug the device until you can. These updates fix nine vulnerabilities that routers are vulnerable to and are currently being exploited in the wild. You may want to visit that page even if your ASUS router isn’t listed, as there are a number of patches and updates for other devices found there that you may benefit from installing.
The oldest of the patched vulnerabilities is nearly five years old and allows arbitrary code to be executed on the router. Other vulnerabilities are much more recent, including a high-severity bug that allows for both denial of service and code execution. Bleeping Computer also repeats ASUS’ warning to update your password in case it was collected by an attacker, doubly if the password is the default one that your ASUS router shipped with.
As for the rest of us, visit your routers support page in case there’s a patch for you too.
