This "Always Works" command/hook for Claude Code is mega handy. I've lost count of the number of times it has told me that things are working when it hasn't even checked. pageai.pro/blog/31-claude…
A bunch of apps I’ve been poking around with lately interact with Dataverse using $batch queries. Not seen much chatter about it, but really handy to subvert intended logic when the queries and writes are just … there. Any authz issues are super obvious too 👁️👁️
Microsoft have released a great (free) Zero Trust Workshop that helps organizations with an actionable roadmap to achieving zero trust in their organization. youtu.be/xVWr1ml47_g aka.ms/ztworkshop 00:00 - Introduction 00:07 - Zero Trust 101 00:22 - NIST zero trust…
A chat with my teenage son about SIEM detection rules (he saw me working on some) pivoted into MITRE, TTPs, network services/ports, and a trip around Shodan. Ridiculous what's still exposed to the web in this day and age. We just spent 15mins looking at RTSP and VNC screenshots.
Even though Microsoft provided a PowerShell command in April 2025 to disable the SMTP DirectSend feature in Exchange Online, we are still seeing attackers successfully reach the inbox for organizations that do not have their DMARC DNS Record set to Reject or Quarantine. According…
Came across this really useful blog post, I recommend reading it if you're doing any sort of development in Claude Code: memo.mx/posts/claude-c…
👋 Check out this new Microsoft Entra blog post 👇 Microsoft Entra Private Access for Domain Controllers is now in Public Preview techcommunity.microsoft.com/t5/microsoft-e…
Wow, this is a great development!
Wow, this is a great development!
Came across a SPF record today that allows approximately 79 octillion IPv6 addresses (79,228,162,514,264,337,593,543,950,336) to send email from the domain in question... Somehow I don't think that's strictly required!
No more MOERA domains for email (which you shouldn't be using the first place 😉) Limiting Onmicrosoft Domain Usage for Sending Emails techcommunity.microsoft.com/blog/exchange/… #MExchange #ExchangeOnline #MOERA #Security
Attackers know how to find your weak and misconfigured Applocker rules. Now you can too.... 🧵Just finished putting together a new tool to find weak and misconfigured AppLocker policies. It’s called AppLocker Inspector. Here’s how this tool came to be and what it does that’s…
Microsoft isn’t disclosing this so: M365 Copilot allowed users to access files without producing an audit log. All you had to do was ask Copilot to not link to the file. You don’t even have to ask; it sometimes just happens. If your org uses Copilot your audit log is likely wrong

Great find and writeup by @ZackKorman M365 Copilot allows file access without audit logs if asked not to link, bypassing Purview restrictions and sensitivity labels, risking undetected data exfiltration. Microsoft won't disclose, trust and compliance are at stake.

AI is just a ploy big Big Language to get non-Americans to finally give up and just accept US English spelling.
we are in for a few years of security nightmares
The reasons we fear app control are industry-made problems If we invested half the effort into improving app control that we do into EDR, we would be a lot more secure and have more resources to devote to the next things Instead, we'll forever chase arbitrary code execution...
