Marcus Sachs, Rob Shein, David Litchfield "Zero-Day Exploit: Countdown to Darkness" ()
There exists a 0-day vulnerability (в другом описании vulnerability) in a particular (тег particular) line of SCADA (ключ слово SCADA) Master (в другом описании Master) products that are widely used in petrochemical facilities. Furthermore, since the telemetry between the Master and the RTUs (the units located at valves (valves в других книгах), gauges, etc.) is particularly fragile under attack (attack в других книгах), 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 (invalid в других книгах) data; the way in which (в другом описании 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 (ключ слово networks), and work begins (в другом описании begins) on replacing (смотрите replacing) RTUs. This, however, has no effect, and as time passes the ripples of the attack spread (смотрите 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.
