Eireann Leverett, Senior Security Consultant for IOActive, to present at GreHack 2013


PRESENTER: Eireann Leverett, Senior Security Consultant for IOActive
PRESENTATION: Vulnerability Inheritance in Programmable Logic Controllers
CONFERENCE: GreHack 2013
LOCATION: Amphi Vaujany Grenoble, France
DATE & TIME: Friday November 15, 2013 at 12:35pm

Eireann Leverett will deliver an academic paper that illustrates how over 200 types of PLCs and EWSs share a common runtime library. This commonality makes them susceptible to authentication bypass vulnerabilities discovered by Reid Wightman, Senior Security Consultant at IOActive, over a year ago. Using this flaw, an unauthenticated attacker could upload ladder logic to the PLCs or halt programs that were running. Eireann and Reid scanned the Internet to see just how many are vulnerable, and then shared the data with 30 countries. The paper Eireann is presenting provides a detailed description of the problem, and the number and distribution of vulnerable devices they found exposed to the internet a year after the vulnerability was announced.
