In the recent DDOS attacks on OVH and DYN, the attacks were committed with redirection of terrabytes of data using botnets of video devices.
It is already known that earlier botnets of millions of computers were being created to conduct such attacks. Now it appears that in certain cases, data traffic of as little as 4Mb per second could bring down networks.
A research organization TDC has reported that a single laptop producing around 180 Mbits per second can send certain commands that can trick the firewalls of CISCO and others to bring down the network.
Security managers need to check the vulnerability in their servers and implement the corrective steps that are being recommended by the security companies.
