HART As An Attack Vector: Current Loop to Application Layer presented at S4 2014

by Alexander Bolshev,

Summary : HART and HART-over-IP are widely deployed ICS protocols that have received minimal attention in the research community. This has changed as Alexander will show HART has the same insecure by design issues as other ICS protocols. More importantly Alexander will use access to the 4 to 20mA control loop to attack the entire plant, including applications and protocols that appear to be unrelated to HART.
Alexander finishes with a demonstration of tools he has released to enumerate and assess a system that uses HART.
