Please note, that the information presented in this post may be outdated. An updated technique has been posted here. The German ISP o2 Alice Hansenet enforces their customers to use the router that is distributed to them along with the contract.
In this post I will show you how to extract your VoIP data from a configuration backup file which can be downloaded through the IAD web interface. Since Sphairon uses the same backup file structure and encryption scheme on most if not all their devices, this technique is quite generic. Any comments should be posted to the corresponding thread in the IP-Phone-Forum. Now use the decrypter to convert your config. My tool does not contain any harmful code. Please run it in any type of sandboxed or virtualized environment if in doubt.
Open the. The data encoded into the username can be found at least in my case on the label under your IAD The above example contains 3 VoIP telephone numbers, each with their own username, password and registrar. Note: In my example each telephone number was equal to the according username. Furthermore all registrars were equal. The file rc. Furthermore you will find some root-user password hashes for samba, ftp and telnet. If you manage to crack any of the hashes or if you reverse engineer any of these images I would be happy to hear of your results.
What is the magic behind your tool and how did you write it? Once the file structure and the encryption algorithm were understood, I simply wrote a decryption routine. Will you make the file structure and the encryption scheme publicly available? Please credit me if you use information gathered by me. Why do they store the length of the secret along with the ciphertext? Pingback: WTHack — Onlinectf. Theme Rustic 2.
