Sachs, "Zero-Day Exploit: Countdown to Darkness"

More Rob Shein, David Litchfield, Marcus Sachs, "Zero-Day Exploit: Countdown to Darkness: Countdown to Darkness" ?There exists a 0-day vulnerability in a particular line of SCADA Master products that are widely used in petrochemical facilities. Furthermore, since the telemetry between the Master and the RTUs (the units located at valves, gauges, etc.) is particularly fragile under attack, the attackers are able to take a two-tiered approach to the damage they cause. The vulnerability is designed to simply replace a small bit of code in the SCADA Master so that upon communication with the RTUs, it will unpredictably send invalid data; the way in which the communications are invalid also varies somewhat. The symptoms of this appear not at the Master level, but in the RTUs themselves, which have unpredictable results. The first set of disasters occur as valves fail to close or open, or particular RTUs cease providing data. It takes a bit of time for law enforcement to have a solid handle on things, as they are currently battling their own issues, but they notice the pattern. The SCADA systems are immediately segmented from other networks, and work begins on replacing RTUs. This, however, has no effect, and as time passes the ripples of the attack spread. Gas stations run out of gas, followed shortly by freight carriers. Private individuals and local police and fire departments are not far behind. Disaster can only be prevented by Reuben, an elite cyber-security researcher who stumbles across the plot while contracting for the federal government.
