Decoding Comcast’s Caller ID!

It’s been a while since I’ve written about this, but there’s been a flurry of activity recently, and it’s time for me to post about this!
Comcast’s caller ID encryption has been broken! It’s actually a very simple AES256-CTS encryption. The tricky part is getting the key and the caller ID information. Getting the encrypted information is actually very simple: just connect to the right XMPP server. Getting the key, however, requires decrypting a flash file.
Anyway, with the help of a guy who calls himself Henry (if you want any more credit/a link to your site/whatever, let me know!), I’ve gotten a small python script working which will connect to the correct server and listen for the encrypted info. When it’s found, the information will be decrypted, and displayed in the terminal. Basically, we can get the unencrypted information! From here, it should be trivial to do whatever we want with it! I plan on attempting to write a Network Caller ID server with the current code as the base, but I’m not sure how much time I’ll really have to work on that/how far I’ll get. (continue reading…)
