A hands-on foray into the IOCTL_AFD_RECEIVE Fast-I/O path: stalking AfdFastConnectionReceive in WinDbg, decoding the AFD_SENDRECV_INFO / WSABUF triad, flipping TDI flags for peek-and-poke tricks, a...
A deep-dive into the IOCTL_AFD_SEND Fast-I/O path: snaring AfdFastIoDeviceControl hits in WinDbg, reverse-engineering the AFD_SEND_INFO / WSABUF chain, and blasting raw TCP payloads straight from u...
A walk-through of the bind + connect IOCTLs: capturing AFD.sys IRPs with WinDbg, reverse-engineering the buffers for IPv4/IPv6, and completing a manual TCP three-way handshake on Windows 11—still z...
A quick look at how I used WinDbg and NtCreateFile to craft a raw TCP socket via AFD.sys on Windows 11, completely skipping Winsock.
