Anthropic - AI can do cyber without much human.

Me - AI can you help me with this research:

I’ve been finding the #Entra Usage & Insights report useless lately when it comes to #passkey reporting.

Why? It’s broken.

It’s concerning that this seems to be an ongoing issue that isn’t tenant specific and Microsoft hasn’t caught it.

Going right from @WEareTROOPERS in Heidelberg to @fwdcloudsec in Denver ✈️ - from one excellent conference to another!

I’m looking forward to speaking Monday @ 2:00pm in track 1 on the dangers of #nOAuth, with some new and tweaked slides and talking points!

#Entra #EntraID #infosec #cybersecurity #mvpbuzz

At @WEareTROOPERS I dropped new research on #nOAuth, an abuse of #EntraID that allows you to spoof users in vulnerable SaaS applications.

The attack is still alive and well.

You can read all about it here:

New nOAuth Abuse Alert: Entra Cross-Tenant Saas Apps at Risk

A look at a recent spam scam email that I received, trying to understand what mechanism the attacker is using to deliver the scam email.

Haven’t been highly active on the socials lately… trying to change that a bit.

En route to #HIPConf24, where I’ll be presenting on #UnOauthorized tomorrow, as well as joining a panel with Thomas Naunheim on workload identities, and having some good hallway conversations. Looking forward to seeing folks!

I've been quiet on here for a while, but wanted to share the blog that details much of UnOAuthorized from my #bhusa talk yesterday.
