People learn in different ways. I wrote Dynamic Incident Response, but not everyone wants to get cozy with a 666 page PDF. So I made a Gemini Notebook too: ask questions, critique, interact how you want. Free.

Heads up, there is a 1-day full MikroTik RCE chain against SSH being used in the wild. Patch was released yesterday, so if you have a MikroTik router with ssh open on the internet, it may already be compromised. Detection guidance and IOCs courtesy of @CERT_Polska_en cert.pl/en/posts/2026/09/vul…

No CISO has ever regretted the training. Here's why one still blocks 5 days a year for it. #Cybersecurity

Each of my executive-briefing templates answers what senior leaders actually ask. What happened, what it means for the organization, and what we should do. They're based on what I wanted to see and share as a CISO.

TShark isn't just Wireshark without a mouse. Andy used it to prove SMB 3.1.1 compliance for auditors when no Windows tool could. Watch how display filters + field extraction solve real-world problems.

One artifact rarely tells the full story.
Jump Lists. LNK files. Prefetch.
Each captures different activity on a Windows system.
The challenge is connecting them.

A small utility in Asia was targeted by China’s top cyber unit. The attackers ran a sustained campaign for over 300 days. They got into the IT network. They never reached OT. Why? The general manager put the basics in place and built a security culture. That’s it. No AI. No million-dollar SOC. Fundamentals. Robert M. Lee called it his favorite case study at RSAC 2026.
