There has been significant progress in securing IT and OT networks. However, one would expect that after 23 years, the “OT” security community would be further along in securing critical infrastructures from control system and other kinetic cyber incidents. Unfortunately, the engineers needed to safely secure control systems are generally not involved while the network […]
Sam Houston State University paper – “Who’s in charge of OT security”
The Institute for Homeland Security at Sam Houston State University published my paper –Whos_in_Charge_of_OT_Security.pdf (ihsonline.org). CISOs have traditionally been responsible for cyber security of enterprise IT networks excluding the control system (operational) assets which were under the purview of the engineering organizations. After the 2006 Gartner Research paper that coined the term “OT”, the CISOs […]
Government and industry are indifferent or unaware of critical infrastructure kinetic cyber incidents
Pagers and walkie-talkies are still used by US critical infrastructures such as power, water, and oil/gas. It appears the compromise of the Hezbollah pagers, walkie-talkies, and solar systems were supply chain attacks, somewhat akin to the Farewell Dosier attack on Gazprom in 1982. The Hezbollah pagers and walkie-talkies needed to be remotely actuated, making them […]
Government and industry organizations’ gaps in understanding control system cybersecurity
Cybersecurity programs assume organizations can recognize control system incidents as being cyber-related. Yet the lack of control system cyber expertise by government organizations including NTSB, FDA, FBI, TSA, EPA, CISA, and DOE have not identified control system incidents as being cyber-related. The five cases discussed were fatal catastrophes. In all cases, NTSB identified control systems […]
Critical infrastructure cyber security incident reporting is not working
Viable cyber security programs require organizations to recognize incidents as being cyber-related. That is generally straightforward for IT and OT network-based cyber incidents. However, the same can’t be said for control system cyber incidents in any sector. People in cybersecurity are comfortable with saying that insider threats (to data and IT systems) can be either […]
Follow-up: Report of another PLC compromised using cyber means
(cross-posted from the SCADASEC mailing list – posting was reply from Marina Krotofil) A couple of other friends reached out and asked for more details and more thoughts.So I wanted to add a couple more things. Note, that I do not havevisibility into the EXACT configuration of LvivTeploEnergo infrastructure,which is insanely complex as well as […]
Report of another PLC compromised using cyber means
(cross-posted from the SCADASEC mailing list – posting was reply from Marina Krotofil) I just went through the Dragos report, the Wiredarticle, the Ukrainian sources, Nozomi report, some more foreign articles,Medium articles, Dale Peterson opinion piece, CERT-UA page, spoke to someICS folks who already looked into the sample, and I have so many questions. 1. […]
CrowdStrike, SolarWinds, and Stuxnet demonstrated the cyber fragility of IT and OT systems
Fifteen years ago, Stuxnet demonstrated that getting to the Engineers’ Workstations can cause devastating damage. Three years ago, SolarWinds showed that malware could be inserted into the update cycle. Two weeks ago, CrowdStrike demonstrated that Engineers’ Workstations are still cyber vulnerable to automatic updates that are fully trusted. It was evident that OT (and IT) […]
Anybody listening? Another report of a cyber attack on Industrial Automation and Control Systems.
“Everybody talks, nobody listens. Good listeners are as rare as white crows” – Helen Keller Wired[1] cites a Dragos report[2] on a cyber-attack on ICS with affect on well-being of society. The attack was performed using the MODBUS protocol[3] and was able to manipulate ICS devices (ENCON PLC) to cause heating systems to fail in […]
Issues with Identifying Control System Cyber Incidents – MORS presentation
July 17, 2024, I gave a presentation to the Military Operations Research Society (MORS) on “Issues with Identifying Control System Cyber Incidents.” Government and industry organizations tend to under-report, and under-share control system cyber incidents. Identifying control system cyber incidents is much less mature than IT and OT network anomaly detection with minimal applicable cyber […]
