⚡ 𝗧𝗼𝗱𝗮𝘆 𝗶𝗻 𝗖𝘆𝗯𝗲𝗿𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗛𝗶𝘀𝘁𝗼𝗿𝘆 – 𝗗𝗲𝗰𝗲𝗺𝗯𝗲𝗿 𝟮𝟯, 𝟮𝟬𝟭𝟱

On a cold December evening in Ukraine, the lights began to go out.

Not because of a storm or a fallen transmission line. But because an unseen adversary, who was patient, disciplined, and already deep inside Ukraine’s networks, made its move.

Inside three regional power companies, operators watched helplessly as their mouse cursors began to move on their own. Breakers opened. Substations went dark. And within minutes, 230,000 people were without power.

It was the world’s first confirmed blackout caused by a cyberattack.

In Sandworm, Andy Greenberg follows the trail back to the group behind it. An elusive GRU team whose operations would ripple across the globe. What makes this moment unforgettable isn't just the technical achievement of penetrating industrial control systems…

It’s that December 23rd proved a new reality: code could now disrupt cities, societies, and the physical world itself.

Greenberg’s investigative storytelling captures the tension, the human impact, and the geopolitical stakes behind an attack that forever changed how we think about cyberwar.

Solaranlagen sind ein Eckpfeiler der Energiewende – und gleichzeitig ein unterschätztes Angriffsziel. Viele Anlagen setzen noch immer auf das uralte Modbus‑Protokoll, das weder Verschlüsselung noch Authentifizierung kennt. In einer Zeit, in der KI-basierte Angriffstools automatisiert ganze IP‑Bereiche scannen, Register auslesen und Steuerbefehle injizieren können, wird diese Schwachstelle zu einem echten Risiko für Netzstabilität und Betriebssicherheit. #OTSecurity #Energiewende #RenewableEnergy

The year 2025 is slowly coming to an end.

End of years can be joyful and relaxing, exciting and wholesome, full of reflection and gaining energy for the new year. This time can also be lonely and sad, incredibly stressful and terribly difficult to navigate, with folks barely making it through.

Let's be mindful and considerate - and help each other to move the needle. Now and in 2026. 💜

An investigation in France is underway after malware was discovered on an Italian passenger ferry, prompting the arrest of a crew member and international coordination with Italian authorities.

Officials confirmed the malware was neutralized without operational consequences, but the case underscores growing concern around cyber risks in maritime and transport environments, where IT and operational technology increasingly intersect.

How should threat modeling evolve for vessels and transport infrastructure?

I spent a couple months arguing with Claude and Copilot while building FrostyGoop variants for DNP3 (and Modbus), keeping detailed notes on what worked and what didn't. At S4, I'll share my honest assessment: where these tools actually help, where they fail, and how much skill an attacker needs to make them useful.

See you in Miami!

Cybercrime durchläuft seine eigene industrielle Revolution! Angreifer setzen laut Fortinet Threat Predictions 2026 zunehmend auf autonome KI-Agenten, die ganze Angriffsketten selbstständig steuern – schneller, skalierbarer, effizienter. Zwischen Erstzugriff und wirtschaftlicher Ausbeutung liegen oft nur noch Minuten. Parallel professionalisieren sich Untergrundmärkte weiter und entwickeln sich zu vollwertigen Crime-as-a-Service‑Ökosystemen. #Cybersecurity #Fortinet #Cybercrime #OTSecurity

🇺🇸 For federal #manufacturing operations, the stakes are especially high. Unlike the commercial sector, where profitability drives decisions, federal facilities focus on achieving national objectives that are often intangible, hard to quantify, and central to U.S. resilience against state-sponsored threats.

While #OTsecurity fundamentals apply everywhere, the federal risk tolerance is far narrower, as any disruption can undermine critical national capabilities.

From 🩺 medical devices to currency to 💡 energy systems, #federal manufacturing is a strategic asset. Safeguarding it means elevating #OT security to a core pillar of national security and mission assurance.
