### Half Measures and Full Compromise: Exploiting Microsoft Exchange PowerShell Remoting

Collection of all materials concerning my Exchange PowerShell Remoting research. It includes OffensiveCon 2024 video and 4 blog posts, which include all the technical details.

Chain of 3 gadgets (Arbitrary File Write + Arbitrary File Read + Local DLL Loading) to achieve the RCE on Exchange is fully described in the [3rd blog post](https://www.zerodayinitiative.com/blog/2024/9/18/exploiting-exchange-powershell-after-proxynotshell-part-3-dll-loading-chain-for-rce).
