The BrickerBot is a malicious worm that seeks out and destroys routers, cameras and other internet connected devices.
By overwriting all configuration and settings data before rebooting the device the device is bricked or rendered useless in what has been dubbed a PDoS (Permanent Denial of Service) and the hacker behind the worm known as The Janitor.
“The good news is that remembering a simple step in the setup process, you can make sure that your smart or connected devices do not fall into BrickerBot’s crosshairs and it is as simple as changing the default password on that device.”
The Janitor developed the BrickerBot to actually make the internet safer by disabling any device accessible on the internet with an open Telnet service and default admin credentials effectively wiping out the hardware exploited by the Mirai botnet, a powerful IoT network of compromised smart devices that were responsible for bringing down large parts of the internet on October 21, 2016 (Wikipedia Entry here).
The Janitor has self-identified the BrickerBot project as a form of “Internet Chemotherapy”. A harsh treatment designed to address a systemic problem set to grow beyond the original Mirai Botnet attack and hopefully make consumers and manufacturers more aware of what it takes to become a part of a safer internet.
