Today’s stories feel like whispers behind closed doors — exploits quietly for sale, malware slipping past EDR, and nation-state campaigns that don’t need loud moves to win. From healthcare to energy grids, the threat isn’t always in the attack — it’s in how little we see of it.
🛠️ Fortinet Zero-Day Allows Arbitrary Code Execution
Fortinet is once again in the spotlight, disclosing a critical zero-day that allows remote code execution on vulnerable systems. Details are sparse, but exploitation is already rumored. Security firm reports say a working exploit may be circulating in dark web markets.

🕳️ Chinese APT Exploits EDR Blind Spots for Espionage
A new campaign tied to a Chinese APT group shows how attackers are exploiting gaps in endpoint detection and response (EDR) visibility — particularly around system-native tools and living-off-the-land techniques. Espionage isn’t flashy. It’s efficient.

💭 Reflection
It’s Day 104, and I’m seeing the same lesson in every feed: visibility without clarity is just noise. Whether it’s blind spots in EDR, delayed patch cycles, or phishing that adapts in real time, we’re not losing because of lack of tools — we’re losing because the threats know where we aren’t looking. As I grind through CISSP prep, it’s clear: monitoring isn’t enough. We need interpretation. And speed.
This isn’t a chess game anymore. It’s hide-and-seek — and the prize is control. 🎯🧠🛡️
