Ralph Langner was among the first security experts to analyze parts of the Stuxnet worm s code devoted to manipulating programmable logic controllers by Siemens. Langner is keeping busy with Langner Communications, his consulting firm which works with ICS vendors and their customers on security issues. He was profiled (peevishly) in Vanity Fair (a piece that prompted a hillarious, written response from Langner) and spoken at the uber-hip TED Conference. Threatpost caught up to Langner at the recent S4 Conference, an annual gathering of the leading researchers in industrial control system security in Miami.
