IoT_reaper Botnet information:: DIR-850L, DIR-600, and DIR-300

Security researchers have recently warned that a new botnet called Reaper has actively attempted to target unpatched IoT devices, which are more vulnerable to attack. The new botnet targets vulnerabilities previously disclosed in DIR-850L, DIR-300 and DIR-600 routers that have already been resolved by D-Link with firmware patches.  If you have not updated the firmware for  your DIR-850L, DIR-300 or DIR-600 routers, your devices are more vulnerable to this new botnet attack. We urge users to immediately go to their local D-Link support site to update their devices with the latest firmware.
