Network university attacked by their own lights, and vending machines
The network of an unnamed university was attacked by lamps, street lamps and vending machines on the campus.
That turns out a safety report of the American telecom provider Verizon. In total, 5,000 internet-connected devices, the university have been attacked. The majority of these devices are connected to the ‘internet of things’-segment (IoT) of the campus network, which is on the campus.
The university has a large part of the equipment present on the campus connected to the network, so that, for example, the lighting from one central point can be controlled.
The gadgets made every quarter of an hour hundreds of requests to a DNS server, which was searched for fish and other seafood. The internet accessible to students was therefore very slow.
The university knew the botnet will eventually stop by the passwords to change on affected devices. The attackers could thus no longer malware on the gadgets install.
The botnet used in the attack looks like a very local version of the Mirai-botnet. There are IoT devices from all over the world, that cyber attacks can be used.
Mirai shrugged, for example, the DNS provider, Dyn offline, causing many large sites were inaccessible. It was also Mirai used to access the internet in Liberia offline.
