So, someone I know has a cheap security DVR from Aldi. Distributed by "WinPlus Australia", it's been designated the brand and model "Cocoon Digital Video Security System IT115008".
With the latest hype around the Mirai botnet commandering things exactly like such a security DVR, I decided to get in touch with the local distributor and ask them if any issues had been reported, advisories released, or updates made available.
