I was one of the first to clear the new Certified Azure Red Team Expert (CARTE) exam earlier this week! Once again a fantastic training and lab by Nikhil Mittal, where we are encouraged to take the role of hacktivists to compromise the Azure environment of a big oil corporation!

🚀 Releasing the Microsoft Teams module for GraphSpy! This was one of the most requested features so far! It is currently completely using the undocumented MS Teams API (api.spaces.skype.com), making it possible to obtain an access token for it using FOCI refresh tokens!

I just published my research into bypassing Adversary-in-the-Middle (AiTM) phishing detections! 🐤 No real canaries were harmed during this research, although I can't say the same about our SOC after playing with the last technique... 😂 insights.spotit.be/2024/06/03/cli…

Normal users are not anymore able to create Bulk AAD join tokens! That enabled DoS attacks against users' home tenants as they could exhaust Entra ID by filling it with user objects: aadinternals.com/post/dosingaad… Thanks to Keanu Nys for noticing and bringing this up!

Microsoft seems to have recently deprecated the legacy account.activedirectory.windowsazure[.]com endpoint, which GraphSpy was using to list and add MFA methods for a user. GraphSpy 1.4.3 now utilizes the mysignins[.]microsoft[.]com API now (which is also a FOCI resource!)
