Could you build this?
No Re-implementing Responder in Go demands in-depth reverse engineering of proprietary Windows authentication protocols (NTLMSSP, SMB, Kerberos, LLMNR) and low-level raw network socket handling.
What it would actually take: This project requires building custom network servers in Go implementing LLMNR, NBT-NS, mDNS, SMB, MSSQL, HTTP, and LDAP protocols down to the raw binary wire format. The hard part is accurately replicating Windows challenge-response authentication handshakes, handling binary NTLMv1/v2 message signing, and raw packet crafting without dropping connections or triggering basic IDS alarms.
