The Silent Cry of PLCs: The Cost of Living on 'Default' in Industrial Systems
A deep dive into the world of OT security, legacy protocols like Modbus, and why the 'air-gap' myth is the biggest threat to industrial infrastructure.
Breaking the Factory Default: Why ‘Modern’ Security Solutions are Crashing OT Networks
Everyone is talking about IT/OT convergence, but shoving office-grade scanners into a factory network is a recipe for disaster. Here’s why your legacy PLCs hate your 'next-gen' security tools.
When the Valves Start Turning Themselves: The 'Air-Gap' Fairytale and Harsh Realities in Industrial Systems
Think your industrial network is truly isolated? Let's talk about the 'Air-Gap' myth, why Modbus is dangerously polite, and the cold reality of OT security from a Red Teamer's perspective.
Not Vanilla Ice Cream, but Industrial Disaster: The Air-Gap Lie and the Defenseless World of PLCs
Think your industrial systems are safe just because they aren't on the internet? Think again. Let’s talk about the reality of OT security and how a simple Python script can wreak havoc on an unprotected PLC.
The Silent Killer in the Factory: The Cold Reality of the 'Force Coil' Command in OT Systems
Hacking a server in the IT world leads to data leaks; hacking a system in the OT world leads to physical disasters. Let's dive into the vulnerabilities of Modbus/TCP and why the air-gap myth is dangerous.
Hitting the 'Reset' Button in the Factory: Why Red Teaming Industrial Systems Gets the Heart Racing
A deep dive into the high-stakes world of Industrial Control Systems (OT) security, featuring a 'learning-the-hard-way' story about how a simple Nmap scan can halt an entire production line.
When the PLC Heartbeat Stops: Red Teaming Industrial Systems and the Harsh Reality
In the world of ICS/OT, a single hex code can be the difference between a smooth operation and physical disaster. Here's why security in the field is a completely different ballgame.
The Packet That Stops the PLC: Air-Gap Fairy Tales and Realities in the OT World
When you intercept a 'Function Code 05' request from an unauthorized IP on Wireshark, you realize within seconds that the physical valve or motor is no longer under your control. Welcome to the world of OT.
Back to Factory Settings: A Day Among Rusty Pipes and Exposed PLCs
Think air-gapped networks are real? Think again. Let's dive into the world of OT hacking, where Modbus is king and "reboot" is a terrifying word.
