I am increasingly of the opinion that InfoSec is best described as "and..." It's IT and security. It's networking and security. It's business process and security. It's product development and security. It's finance and security. It's people and security.

Adolescent eating disorders don't announce themselves loudly, more often than not it's a slow accumulation of things that individually have reasonable explanations. But the disorder has the second highest mortality rate of all mental illnesses, second only to opioid addiction. 1/

This week we launched HeldInTheDark.com, a simple 5-question quiz. The quiz is free to take. It's not about diagnosis, just an honest look at what you are actually seeing in yourself or in your child. 2/

If you need urgent support, call the National Alliance for Eating Disorders helpline at 1-866-662-1235. But if you are quietly wondering and worrying, Held In The Dark just might provide some answers and some encouragement. 3/3

7 years ago, our family felt lost and alone navigating an eating disorder. Today, I'm proud to share Held in the Dark, written by my wife Jennifer Longenecker & daughter Heather Elizabeth. We hope it helps others find hope sooner. Pre-order: barnesandnoble.com/w/held-in… #MentalHealth

Written together from both the child’s and the parent’s perspective, Held in the Dark offers an honest, deeply personal account of that journey. But more importantly, it offers understanding, practical guidance, and hope to families facing an extremely challenging experience.

If sharing our story helps even one family feel less alone, find support sooner, or hold onto hope during their darkest moments, then every page will have been worth writing. We hope it becomes for others the companion we wish we had when our journey began.

A tripwire that kills the session and revokes privs is a strong defense, for any anomalous volume of high-impact action (device wipes, account disables or deletes, password resets, file deletes, etc). Check all your device management platforms. Today it’s intune, tomorrow ???
Taken from the Stryker Handala / Intune Detection Pack v2 "Check PIM role settings for Global Administrator, Intune Administrator, and Cloud Device Administrator. If you see only the "Require Azure MFA" checkbox and no Authentication Context configured, you have the same gap that enabled the Stryker wipe. Configure Authentication Context with FIDO2 or certificate-based auth today. Enable Intune Multi-Admin Approval for wipe, retire, and delete actions. Tenant Administration > Multi Admin Approval. Under 10 minutes. No additional licensing required. Deploy Rule 13 (bulk wipe threshold alert). Five wipes in 15 minutes from a single identity fires the alert. Wire it to a Logic App that calls revokeSignInSessions on the triggering account via Microsoft Graph. " link to Detection Pack v2 blog and direct download. Please share so others can lock down their InTune environments please threathunter.ai/blog/iran-ha…

Beginning about a decade ago, my family muddled our way through an adolescent addicted to an eating disorder. The whole while we thought we were alone in this struggle and had no idea how to support our daughter through it. #MentalHealthAwareness 🧵

Through the course of this year my wife and my daughter wrote the book we wish existed when we were in the thick of things. This is a very personal book, from the perspective of both the parent and the adolescent, with real talk about the struggles for both.

In early 2026, "Held in the Dark: Finding Light and Hope While Supporting Your Adolescent Through an Eating Disorder" will release. We hope our story can give hope to other families that feel alone and afraid, as we were then. #mentalhealth

Northern lights seen from Henderson Texas (32°9’N) covered so much of the sky I had to use a wide angle setting to get it all in frame! #aurora #txwx
