From IT World:
A German steel factory suffered massive damage after hackers managed to access production networks, allowing them to tamper with the controls of a blast furnace, the government said in its annual IT security report.
The attackers got in through spear phishing, then were able to access the ICS directly.
I’m expecting 2015 to be an interesting year for ICS security.
The Korea Hydro and Nuclear Power Co Ltd (KHNP) and the government said only “non-critical” data was stolen by the hackers, and that there was no risk to nuclear installations, including the country’s 23 atomic reactors.
South Korea’s energy ministry said it was confident that its nuclear plants could block any infiltration by cyber attackers that could compromise the safety of the reactors.
“It’s our judgment that the control system itself is designed in such a way and there is no risk whatsoever,” Chung Yang-ho, deputy energy minister, told Reuters by phone.
“It is 100 percent impossible that a hacker can stop nuclear power plants by attacking them because the control monitoring system is totally independent and closed,” the official said.
100% percent impossible? That sounds like a challenge.
I’m willing to wager that “non-critical” data could be a good starting point for crafting a more sophisticated attack. But of course, nothing has ever jumped an air gap…
I’ve been reading through Kim Zetter’s excellent new book, Countdown to Zero Day: Stuxnet and the Launch of the World’s First Digital Weapon and saw this reference to Sandia (and indirectly, to my colleague John Mulder):
“In a 2009 report on 60 Minutes , researchers at Sandia National Lab showed how they could cause components at an oil refinery to overheat by simply changing the settings of a heating element and disabling the recirculation pumps that helped regulate the temperature.”
I found the article at CBSNews.com, but haven’t been able to track down the actual video.
“The first thing we had to do was actually gain access to the network and that’s, we just got that as launch attack. And then we turn up the BTUs, and then we’re turning off the re-circulator pump. There we go,” Mulder said.
Mulder said this type is simulation is “very” realistic.
The US Resilience Project has released the report Supply Chain Solutions for Smart Grid Security: Building on Business Best Practices, based on results from their March 2012 workshop.
I attended the workshop in March and was very impressed at the time. I felt a little bit out of place–one of just a few engineers in a huge room full of executives–but I thought the resulting conversations were good. I’m glad they captured so much of that in this report.
For anyone interested, here is a soft copy of the presentation John Mulder and myself gave at the IFIP Working Group 11.10 on Critical Infrastructure Protection at National Defense University last Spring: Industrial Control System Field Device Analysis
There’s been a ton of work on reverse engineering PLC firmware, but not a ton on the hardware or supply chain issues. This is a Sandia technical report I published with John Mulder, Jason Trent, and Will Atkins a couple of years ago.
This report describes a research project to examine the hardware used in automated control systems like those that control the electric grid. This report provides an overview of the vendors, architectures, and supply channels for a number of control system devices. The research itself represents an attempt to probe more deeply into the area of programmable logic controllers (PLCs)—the specialized digital computers that control individual processes within supervisory control and data acquisition (SCADA) systems. The report (1) provides an overview of control system networks and PLC architecture, (2) furnishes profiles for the top eight vendors in the PLC industry, (3) discusses the communications protocols used in different industries, and (4) analyzes the hardware used in several PLC devices. As part of the project, several PLCs were disassembled to identify constituent components. That information will direct the next step of the research, which will greatly increase our understanding of PLC security in both the hardware and software areas. Such an understanding is vital for discerning the potential national security impact of security flaws in these devices, as well as for developing proactive countermeasures.
