How To Make A Duplicate SIM Card (Clone SIM Card)

how to clone sim card

let’s talk about the fun stuff. The first trick I will discuss is an activity that is becoming quite prevalant, SIM cloning. If you have paid attention to any cell phone related tutorials in the past, then you may remember cloning being made popular by certain public figures like Kevin Mitnick in order to place calls on the bill of another subscriber. Well, even with GSM this trick still holds relevant. How could such a flaw exist in a system that is obviously concentrated on preventing such fraudulant use? The flaw is within the COMP128 authentication algorithm used as an instantiation of A3/A8 widely used by gsm providers. Unfortunately for these providers, the COMP128 algorithm is just not strong enough to prevent fraud. We attack the algorithm by using a chosen-challenge attack, which works by forming a number of specially-chosen challenges and querying the SIM card for each one. Then by analyzing the responses from these queries, we are able to determine the value of the secret key that is used for authentication. So how do we perform this attack?

Instructions

     First you’ll need the IMSI (International Mobile Subscriber Identifier) number. This string of numbers is usually imprinted on the SIM card itself. This is an example of an IMSI number:
     IMSI:429011234567890
     

     An IMSI is usually 15 digits long, but can be one or two digits shorter.

     Now you have your IMSI number you’ll need the authentication key (Ki), which is unique to your SIM. This number can only be discovered electronically using a SIM duplicator, which is an external device that you will slot the SIM card into.
     

     A SIM duplicator is relatively inexpensive – they can be found at around the $10 mark – and can be purchased at multiple locations. A Google search for ‘Super SIM’ will turn up at least several online outlets.

     When the SIM duplicator is connected to your PC and your SIM card, it will attempt to acquire the Ki number and copy the entire contents. When a new SIM card is placed into the duplicator after this process is complete, that data will be copied and, for all intents and purposes, the new SIM will be identical to the old.

Tips & Warnings

• V2 or later SIM cards are very difficult to copy as additional copy protection and anti tamper protocols have been added to the cards. A V2 card is anything made circa 2002 and later (this includes 3G cards). Any attempt to copy a V2 or newer card could result in the card being rendered utterly useless.
