Cómo estás?
"The SIM works" means that the Service Provider recognizes this SIM and allows to make calls in any state of the SIM (both v1 and v2)? Am i right?
One day you can make calls in v2 mode and the other day - in v1 mode? Oh,
since Ki is originally from a v1-card - there is no problem with v1-mode, sorry.
But as for v2-mode - we can be sure that SP in fact sends RAND and compares SRES's?
Or maybe SP respects any reply with this IMSI as valid?
If it is not a secret - IMSI/Ki of what Service Provider was written to this card? Movistar, Amena, Voda or not Spanish one at all?

Hi Guys,
I hope everybody is fine.

Please keep this post updated.
we all need to know more information about how to crack COMP128 V2 Sim card.

Hello,


I am looking for the SimCard with both Comp V1 & V2 that SirGraham is speaking of.

Does anyone know more about it?

I have been unable to get a reply from him and someone in his websites forum says
that they have the card, that it is Chinese made, but I guess is no longer available.

Please anyone assist.

I'd like to tell you and all guys that writing my comp128 v2 IMSI and Ki to a blank card can be done with the known softwares like woron and others. But the bad news is that the cloned card does not deal with comp128 v2 and that the operator cannot identify it, nothing happens when I put the cloned card into the mobile, but even worse, it says insert sim card!!!!

So for a successful cloning of a comp128 v2 card, we necessary need a card that has in some way the comp128 v2 algo.

Does anyone know how we can overcome this problem?
Cheers
Sarah

Yes, some people over here in Thailand do know how to overcome this problem. We can actually buy the blank SIM cards with COMP128v2 which are fully compliant with GSM specifications, have 64K of memory and are OTA compliant. These SIM cards are fully programmable: ICCID, IMSI, Ki, SMS Center, PLMN, etc.

We can easily program IMSI and Ki into these cards and use them in any GSM network with COMP128 v2: Thailand (DTAC, AIS, True), Singapore (M1, Starhub), India, China, Pakistan, Bangladesh, Nepal, Sri Lanka, Malaysia, Vietnam, Philippines, Indonesia, Australia, USA, Canada, Russia, Europe and Africa.

For more information write directly to my e-mail address: [email protected]
Please don't PM. I am not checking my PM mailbox on the Forum.

Oh yes, you can do that. I have the professional software which is normally available only to GSM and CDMA network operators. This software is very advanced and fully configurable. It can work with any SIM or R-UIM card, we can read and update any file on the SIM or R-UIM card including IMSI and Ki, however some of the files require the knowledge of ADM password.

I think that probablly Comp128 v2 algorithm has leaked already to the public domain. Please correct me if I am wrong.

You can ask Dejan about that. I think he is Guru No.1 in the world (besides Marc Briceno ,Ian Goldberg and David Wagner of course).

I was using SIM Scan to successfully extract Ki already 11 years ago.

Even if all the details of the new COMP128 v2 algorithm are available to the public I believe that anyway this new algorithm is exceptionally strong from the cryptological point of view so nobody at present is able to demonstrate an attack to extract Ki from the SIM card at the current speed of 9600 bps.

The CAVE algorithm (used for authentication in TDMA and CDMA mobile phones) has been available to the public since 1995 but nobody still has claimed to have successfully cracked this algorithm in order to extract A-Key from a R-UIM card.

Yes, this is a very good idea. Although this kind of microscope is very expensive.

There is another method to extract Ki and A-Key from any SIM or R-UIM card but it does not work with 100% reliability unfortunately.

A special device (we call it a "glitcher") is used to perform a glitching attack on any smartcard.

This kind of attack is a bit dangerous, before you are able to obtain the secret key from a smartcard you take a risk of having the card completely damaged

[De Fault]

They are devices that work as standard ISO smartcard readers, as well as standard ISO programmers. Nothing wrong there. In fact, many of the sites sell standard programmers for those that want to tinker with it. But to hack a smartcard, you need the "glitching" function. Basically, the glitcher will initiate communication with the smart card. It then tells the card it wants to write to the card's memory. At this point, the card goes through a security algorithm. Since no one has found the right keys to hack the COMP128 v2 or CAVE smartcards, the glitcher simply cuts it's own power and throws the clock out of phase. It then supplies the normal 5V again. This all happens very quickly, so the security steps are simply skipped

This is the glitching attack description....
