All too often, people claim their systems are air-gapped, and therefore have no cyber vulnerability. But Alternating Current (AC) power cords cross the ostensible “air gap”, and power supplies for laptops, servers, ICSs, etc. have rarely been addressed for cyber security vulnerabilities.
Alex McEachern from Power Standards Laboratory will provide a hands-on demonstration of two types of attack-to-failure of a real, air-gapped ICS at the October ICS Cyber Security Conference (www.icscybersecurityconference.com). McEachern’s demonstration will remotely cyber attack and permanently disable a fully air-gapped system – in this case, a server, a router, and a PLC connected only to each other. Well, that’s not quite true: all three would be connected to a power outlet, which will be McEachern’s vector of attack.
