sim card cloning a brief guide for gsm sim cards


step 1

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.

Step 2
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.

Step 3
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.

Smart card cloning is easy!

The stages• Scan the SIM to extract IMSI (just read it!)
and Ki, the 128 bit key (for COMP128-1
only, so far….)
• Now put the IMSI and Ki into some card
software
• And then copy it into a new SIM card
• We now have a cloned SIM

First we need to read the SIM• A small reader, connected to a serial port.
Home made for $5

Then we need to find Ki
• We need Ki and IMSI, we can use
Simscan from Dejan’s pages that will
break COMP128-1

Here’s the software• Simscan ready to go

Now scanning the card
• Searching for the key

Getting there• The result slowly appears (this one looks
interesting!)

 SIM CARD CLONING By Talalsrilanka. Now we have it!• This was a SIM supplied to delegates at a
meeting, Ki is a bit obvious isn’t it!

Now to create the software• Using some more software from the

Internet called KiSsMi we create the
software for the card

We now need to program the SIM
• We use a single chip PIC computer which
is in a SIM shaped package (GOLD
CARD)
• We use a smart card programmer (easily
bought on the Internet)
• And then we program up the card….

The programmer…..
• With the card ready to go

The software for the programmer• Just load in the software we created with
KiSsMi using VxTools

And we now have a cloned card• Note: My way is rather long! Many people
sell the equipment cheaply…
• Only works with COMP128-1
• So now please think about changing to a
new algorithm……….
