Had the great privilege and a lot of fun joining 🎙️#EntraChat together with my friend and MVP fellow @samilamppu.bsky.social!

🙏 Big thanks to @merill.net for having us - it was a pleasure to be part of the podcast. I hope everyone listening enjoyed it as much as we did recording it!
Thomas Naunheim and Sami Lamppu quietly built one of the most useful open projects for Entra ID defenders.

The Entra ID Attack & Defense Playbook

It’s free, community-driven, and packed with real detection logic and KQL queries.

The availability of GraphApiAuditEvents in #MicrosoftDefender brings significant value to every environment, enhancing capabilities for detecting and hunting #MicrosoftGraph API calls. In my recent research, I’ve created a few resources that I’m happy to share with the community.

🚀🔎 Track Sensitive Graph API Calls with my new #KQL Function for #MicrosoftDefenderXDR

Microsoft has released the new advanced hunting table "GraphAPIAuditEvents" which offers great opportunities to investigate activities based on #MicrosoftGraph API calls.

I'm building a new home for IntuneBrew and would like to share my progress so far.

IntuneBrew.com will serve as the project's landing page, featuring a Quick Start Guide and an overview of key features.

Do you like to know if ownership of privileged objects in #MicrosoftEntra has been delegated to lower privileged users? Graph semantics in KQL and XSPM allow building powerful queries and analyzing data as graphs. I've started to include data from #EntraOps to analyze delegated ownership. (1/3)

So who wants a verified 'Microsoft' and 'Microsoft MVP' label on their profile and all the posts?

I just finished setting up @bluesky.ms as a labelling service.

Go subscribe to the label to start seeing labels on verified MVPs and Microsofties.
