For 8 years, a hacker operated a massive IoT botnet just to download Anime videos

For almost eight years, a hacker has silently hijacked D-Link NVRs (network video recorders) and NAS (network-attached storage) devices into a botnet that had the sole purpose of connecting to online websites and download anime videos.

Named Cereals and first spotted in 2012, the botnet reached its peak in 2015 when it amassed more than 10,000 bots.
