You like device code phishing? You will like Felix Aeppli’s latest research even more. He shows how to backdoor Entra ID phished accounts by adding a new sign-in method. Details and PoC here: blog.compass-security.com/20…

We did it again with #LocalPotato!
A not-so-common NTLM reflection attack allowing for arbitrary read/write. Basically EoP from user to SYSTEM.
Tracked as #CVE-2023-21746 - Windows NTLM EoP
Soon more details --> localpotato.com
