pentesting-msrpc
Testing the Microsoft RPC (MSRPC / DCE-RPC) endpoint mapper and exposed RPC interfaces during authorized engagements. The endpoint mapper listens on TCP/UDP 135 (also reachable over SMB named pipes on 139/445 and HTTP on 593). Covers endpoint enumeration with rpcdump, IFID-to-named-pipe mapping (lsarpc, samr, svcctl, atsvc), DCOM command execution, IOXIDResolver interface discovery, and RPC interface fuzzing.

# Pentesting MSRPC (port 135)
## When to Use
- During authorized Windows/AD assessments when TCP 135 (or 593, or RPC over SMB on 139/445) is open
- When mapping which RPC services and named pipes a host exposes (LSA, SAMR, Task Scheduler, Service Control)
- When you have valid credentials and want remote code execution via DCOM (dcomexec)
- When enumerating network interfaces/IPv6 addresses without authentication via IOXIDResolver
- When researching RPC interface attack surface (fuzzing) on an isolated test host
## Quick Enumeration
```bash
# Dump RPC endpoints registered with the endpoint mapper (135)
