Description: In this video, Limor and Philip from Citizen Engineer, demonstrate how to clone SIM cards and hack payphones to do interesting things. The SIM card section starts with a primer on how the authentication works in the GSM world - challenge / response where the SIM contains the encryption key which is used to encrypt the challenge sent by the base station. Now the problem seems to be that there is no way to retrieve the encryption key directly from the SIM cards and the only way (which also only works for older cards) is to use a chosen plain text attack. This attack is carried out by connecting the SIM to a computer and bombarding it with encryption requests for known plain texts. After enough samples go through, the encryption key can be cracked. Once the encryption key is known it is trivial to clone the card using a writer. The video demonstrates the whole hardware hack on how to build your own reader, however, if you do not have the patience or the necessary skills / equipment then you can purchase one from them directly.
In the later part of the video, Limor demonstrates how to modify Western Electric payphones so that they can be used as a home telephone, for VoIP (Skype) and to make it accept quarters. The whole video is more of a "hardware hacking" session than much of software. Its very well made and is definitely a recommended watch.

Very interesting and a good video!
nice topic. .
can u tell us, what kind of software and the circuit scheme picture that u use?
good job..!!
i want to learn
Well This is great, but wt if in case the sim-card locked... and
this video is old (lame). simcards have counter protection against bruteforce. usually sim card have from 2^15 to 2^16 uses of encryption algorithm then it just dies. not 150k tries. all phone operators of russia had this protection in their sim cards like 6-7 years ago.

intresting video and very good quality!!!
Awesome
Well even if its a old video, still interesting +1 from me.
Nice video to watch but not a lot of info, they don;t really show you anything they just show you that THEY can do it but they dont really show you how.
can you tell me how can i making this is divice can you call me 0091-9978268872
Interesting stuff gonna look more into this +1
Really Awesome Stuff....
where is the video?
