Phone hacking - A technical definition

[p_2001]

@techb,

I tried copying sim some time back last year.... it does not work.. .the sim card locks itself if you try to read it a few times...

the new sim cards (2002 or something onwards) are 128 bit encrypted with mechanism put that makes it impossible to copy ...

the old sim cards could be copied though but even that is useless whenever there are 2 sims for same number the network provider knows instantly and can easily track you down..... unless you have copied someones old sim and want to eavesdrop and know the exact time of call it is useless...


hacking phones can be done by uploading edited android/other os apps with your own code added to it...
like take some already cracked app, add some bits to it and then upload it to some warez forum..... most apps have required permissions like accessing internet and all...

Maybe the cards were PIN protected, like there was a PIN code set on them? it would be logical that it wouldn't allow you to copy data if it had a PIN.
I read a paper somewhere about it, there was a theoretical technique discussed as well, to crack the PIN.

PIN is actually generated by user to protect card content like sms and contacts... it is rather easy to break and very much unreliable..... the customer care ppl ask for last 4 digits of sim card number and issue you a PUK code and the algorithm for various carriers are available on net  to generate the codes yourself..

the SIM has more than that..... if you try to read the card without some correct values (whose name I have forgotten) than the card locks or corrupts itself and even a forensic lab will have a hard time.... you would probably need an electron microscope or something lol...
