Remember when, three years ago, several Mirai botnets hit DNS provider Dyn and caused part of the Internet to be unreachable for most users in North America and Europe? For a moment there it really seemed that IoT security would become an indisputable necessity. Unfortunately, that did not happen, and security professionals and consumers are left trying to minimize the dangers of insecure IoT and industrial IoT devices as best they can. The problem with … More ? The post IoT is an ecosystem, as secure as its weakest link appeared first on Help Net Security .

Over the past few years, cyber threats aimed at a number of critical infrastructure targets have drawn our attention to the security of mission critical networks. These threats have included power grids in Ukraine and Ireland, U.S. energy companies and nuclear power plants, and most recently, at an electric utility on the West Coast where a distributed denial-of-service (DDoS) attack overwhelmed grid network systems with false Web traffic. This was the first documented digital attack … More ? The post Countering industrial cyberthreats with secure, standards-based, licensed wireless networks appeared first on Help Net Security .

Ben-Gurion University of the Negev (BGU) cyber security researchers warn of a potential distributed attack against urban water services that uses a botnet of smart irrigation systems that water simultaneously. The researchers analyzed and found vulnerabilities in a number of commercial smart irrigation systems, which enable attackers to remotely turn watering systems on and off at will. They tested three of the most widely sold smart irrigation systems: GreenIQ, BlueSpray, and RainMachine smart irrigation systems. … More ?

What would it take for attackers to significantly disrupt the 911 emergency system across the US? According to researchers from Ben-Gurion Univerisity of the Negev’s Cyber-Security Research Center, as little as 200,000 compromised mobile phones located throughout the country. The phones, made to repeatedly place calls to the 911 service, would effect a denial-of-service attack that would made one third (33%) of legitimate callers give up on reaching it. And if the number of those … More ?
