🎙️ On this Nexus Podcast recorded LIVE from ☀️ S4 Conference in Miami, #cybersecurity expert Mike Holcomb discusses how state actors may be leveraging hacktivists to target operational technology (#OT).

Holcomb has delineated these groups in what he calls a Converged Actor Framework that categorizes threat actors by the impact and frequency of their incidents. A converged actor is potentially the riskiest given the potential for high frequency high impact incidents.

@ohmu i like #OperationalTechnology and #OT too

𝟖𝟒 targets to hit. Don't miss the User Pillar. 🎯

The new 📃 DoW Zero Trust guidance sets 𝟖𝟒 activities as the OT baseline. The hardest part? Managing third-party risk.

Claroty Secure Remote Access - built for #OT - solves the User access puzzle:
🔸 Just-in-Time: Time-based access & auto-revocation
🔸 Accountability: Record and monitor every session
🔸 Least Privilege: Password vaults and role-based, least privilege access for 3rd parties

🔐 Built for OT. Ready for ZT.

Russell Township police email cut off for weeks after suspected intrusion flagged in Ohio county network #CyberIncident #Ohio #Police #EmailSecurity #VPN #OperationalTechnology https://dysruptionhub.com/russell-police-email-block-ohio/

JLR’s disclosure that a September 2025 cyberattack contributed to a 43% decline in Q3 wholesale volumes illustrates how cyber incidents translate directly into operational downtime, financial loss, and third-party risk.

Extended recovery timelines, supplier liquidity stress, and government intervention emphasize the importance of:

- Incident containment
- OT and manufacturing security
- Supply-chain cyber resilience planning

How should large industrial firms rethink cyber risk modeling after cases like this?

🚨 38% of high-risk cyber-physical systems in water utilities are overlooked by traditional #VulnerabilityManagement. That’s a dangerous blind spot attackers are eager to exploit. 💥

Insecure protocols. Known vulnerabilities. Exposed control systems. It’s not just IT—it’s your water supply. 💧

🔒 Join this webinar on Wed, Oct 15 to uncover the hidden risks and learn how to close the gap with #ExposureManagement that focuses on real-world threats.

Lock down your #criticalinfrastructure, #CISA begs admins
#OperationalTechnology (OT) refers to any technology that deals with physical processes, be it manufacturing equipment, energy distribution, oil and gas production, or some other industrial duty. Long isolated from the public internet but more frequently connected in our modern era, OT systems remain an afterthought for many #ITsecurity teams.

Courtesy of the Irrigation Association, July is 🚰 Smart Irrigation Month, a time dedicated to spreading greater awareness of smart irrigation systems.

Smart irrigation is shaping the future of agriculture, but are you prepared for the security risks that come with it? Discover why protecting these systems is critical and how you can get ahead of potential threats in our latest blog: https://claroty.com/blog/commit-to-securing-smart-irrigation-systems-protection

My team develops #Zeek network analyzers for #OT protocols (see ICSNPP on GitHub). If you're familiar with this work, you know one of the hardest parts about it is getting sample data. If you've got access to traffic for some of the more niche protocols on our list (BSAP, ANSI C12.22, GE-SRTP, GENISYS, ROC Plus, Synchrophasor, etc.) and are willing and able to share a bit of PCAP, would you please reach out to me?

Oops, I forgot one:
I also went to this talk at #SteelCon by Sam Maesschalck about OT.
No, not Operating Thetan, but #OperationalTechnology apparently, which basically means embedded systems etc for manufacturing and utilities etc. and what we can do to try and secure these old/insecure systems that were never supposed to be on the internet....

Die Lage spitzt sich zu, Operation Blackout ist aufgeflogen und zwingt HexSwarm zum schnellen Handeln. Sie sind allerdings noch dabei ein letztes Kraftwerk zu infiltrieren, damit die Destabilisierung zu einem vollständigen Blackout führt. Um Zeit zu gewinnen, haben sie die Administratoren ausgesperrt und das Passwort geändert.
