The Bricker bot made the news a couple of weeks ago as being responsible for knocking unsecured IoT devices offline, rather than hijacking them into other botnets and using them for a DDoS attack like the massive event we saw last year against DYN. This is the third botnet that targets insecure IoT devices, but the only one that is destructive. The second, dubbed Hajime, breaks the into IoT devices, but instead of bricking them, it makes them more secure by disabling remote access to the device from the internet. Of course, Mirai was the first, but it has the same purpose as other botnets, which is to enslave IoT devices and use the computing power of its collection of bots for whatever might please the threat actor behind it.
