ATT&CK Finally Has a Name for Prompt Injection. Now Write the Detection.

MITRE ATT&CK v20 adds five AI techniques to the Enterprise matrix: Direct and Indirect Prompt Injection under Execution, AI-Enabled Exfiltration, AI Result Poisoning, and Impair Autonomous Defenses. Why the placement matters more than the count, what the direct versus indirect split means for your trust boundaries, how MITRE's exfiltration analytic actually works, and the detection gaps you should know about before your next coverage report.

Open Weights Aren't Just Chinese Anymore: Mistral Large 4, Reflection AI's Beam, and the Dolphin Question

Mistral Large 4 and Reflection AI's Beam are the first Western open-weight frontier models in a long while, and neither has shipped a weight file yet.

Webshells, Start to Finish: Build One in a Lab, Use It, Then Catch Yourself

The webshell is the cockroach of offensive security: one line of code, arbitrary command execution, and still everywhere. A deep dive into what webshells are, how attackers plant and use them, how red and blue teams both put them to work, plus a hands-on Docker lab where you build a vulnerable app, drop a shell, use it, and then detect and defend against it three different ways.

The State of AI Automation: Zapier vs Make vs n8n, Through a Red Team Lens

AI automation quietly became critical infrastructure that security never signed off on. A deep look at where automation actually is in 2026, the real differences between Zapier, Make, and n8n, when to reach for each, and why every one of them is a beautiful new attack surface: standing credentials, unauthenticated webhooks, shadow automation, and prompt injection into agents that hold tools.
