I've been researching the Microsoft cloud for almost 7 years now. A few months ago that research resulted in the most impactful vulnerability I will probably ever find: a token validation flaw allowing me to get Global Admin in any Entra ID tenant. Blog: dirkjanm.io/obtaining-global…

knew win10 had the dsquery.dll laying around but never knew what to do with it "rundll32.exe dsquery.dll OpenQueryWindow" will pop open a console for you and you can do some light LDAP recon you can also open with with win + ctrl + f probably useful for VDI/Citrix type tests

What is OAuth Consent Phishing? It’s a social engineering trick where the user grants access to a malicious app. What is Token Replay? It’s when you reuse stolen OAuth tokens to access cloud services without logging in again even after the user changes their password.

You all are misreading the MITRE CVE situation. MITRE ran out of numbers and was not prepared to move to CVEv6.

Make sure your cert requests include the SID of the user you're compromsing or setting persistence on. Strong mapping is enforced this month. support.microsoft.com/en-us/…

Like seriously, if you still have Seamless SSO enabled, you probably aren't even using it and should really look at whether you can go turn it off It's an unnecessary attack surface, especially in 2024 teapawt.net/NathanMcNulty/status/1…
In fact, Seamless SSO also comes with attack surface, so you really should work toward removing anything that is using it to remove risk Windows - PRT via Entra join, Hybrid join, or registered macOS - PRT via Enterprise SSO plug-in iOS/Android - PRT via registration/broker app

💥 Exciting update and launch competition! 📢 Folks, I'm happy to announce another important milestone for @PwnedLabs - the launch of the 𝗠𝗶𝗰𝗿𝗼𝘀𝗼𝗳𝘁 𝗖𝗹𝗼𝘂𝗱 𝗔𝘁𝘁𝗮𝗰𝗸 𝗮𝗻𝗱 𝗗𝗲𝗳𝗲𝗻𝘀𝗲 𝗕𝗼𝗼𝘁𝗰𝗮𝗺𝗽 - and our first certification! 𝗧𝗼 𝘄𝗶𝗻 𝗮 𝘃𝗼𝘂𝗰𝗵𝗲𝗿, 𝗷𝘂𝘀𝘁 𝗹𝗶𝗸𝗲 𝗮𝗻𝗱 𝗿𝗲𝘁𝘄𝗲𝗲𝘁 𝘁𝗵𝗶𝘀 𝗽𝗼𝘀𝘁. 5 vouchers are available and will be drawn randomly. This comprehensive 4-week bootcamp and its structured learning path provide students with foundational concepts, essential security tools and techniques, and instruction in attacking and defending Azure and Microsoft 365 environments. Students who successfully complete the 4-week bootcamp and structured learning path can then attempt the exam lab to try and earn the 𝗠𝗶𝗰𝗿𝗼𝘀𝗼𝗳𝘁 𝗖𝗹𝗼𝘂𝗱 𝗥𝗲𝗱 𝗧𝗲𝗮𝗺 𝗣𝗿𝗼𝗳𝗲𝘀𝘀𝗶𝗼𝗻𝗮𝗹 (𝗠𝗖𝗥𝗧𝗣) certification. This has been one of the main things that our community has been asking for. What can you expect to learn? -> bootcamps.pwnedlabs.io/mcrtp…

Next to token theft for bypassing MFA, this should be your next legitimate concern in the cloud. - residential proxies can give attackers leverage to do unlimited amounts of password spraying. - Blended attacks can be very difficult to detect because the attacker can reside in the same geolocation as the victim. What can you do about it? - require device compliance in CAP - if on AD required hybrid Entra ID join - FIDO2 all admins with RBAC roles. - if using P2 implement identity protection in CAP - emergency accounts with elevated privileges should be the only ones excluded from CAP - lock down service accounts where they can only operate from trusted IPs in CAP. - block unknown and unsupported devices Identity protection has some cool features such as suspicious API abuse protection. Yes, attackers are abusing graph API for reconnaissance purposes. So if you have P2 use it. Why do all this? Attackers will conduct their early operations from the outside to gain a foothold on an internal environment. So if an attacker calls the helpdesk to reset an employee with privileged access, they still won’t get in since they lack a device requirement to satisfy conditional access. Phishing attacks will be in the same boat. This will ultimately cause an attacker to pivot with a C2 implant which could be risky if an enterprise is doing all the above. 😎

I've always recommend the free Microsoft 365 developer subscription as a great way to learn. Having it locked behind a 600 EUR to 3k EUR minimum cost is going to hurt Identity Security learning capabilities for everyone. Very sad to see it like this. devblogs.microsoft.com/micro…

For anyone who needs a refresher (like me lol) on how to explain what kerberos delegations are, this is one of my favorite references from a Def Con class (2019?) by Elad Shamir (a GOAT). Enjoy! media.defcon.org/DEF%20CON%2…
