Cloning of Comp128V2/V3-SIM-Cards

[ProloSozz]

No - it is not yed done ... but I just have a Question about it: as it is known that today, KI of Comp128V2/V3 SIM-Cards cannot be read out ("hacked") yet, what about using the older "programmable Multicards" (6in1/12in1/etc. that are used with "hacked Comp128V1-Cards) as soon as cloning will be possible? Will the old programmable Multicards be normally usable with KI read out (once it will be possible) from Comp128V2/V3-SIM-Cards, or would other type of programmable Multicards be necessary? As I read so far, the only problem is "how to get the KI" - and there is no way so far to get it. But as soon as you have it (along with IMSI etc.) it should be taken for putting into a programmable card. But I did not read if programmable cards of today (that are usable with Comp128V1-SIM-Cards) in theory would work or not - just because KI is not (yet) readable/hackable it is just no topic.

What's the situation so far? Btw: as no system is absolutely secure, I assume that it is just a matter of time until as many information will be available for hacking Comp128V2/V3-Cards. But it could also last several years until ...

Thanks for clarification

1. KI itself is not useful without Algorithm. So you need 1) Algo (v2 or v3 or call it whatever else) and 2) Ki value of the SIM with this Algo. Then you can start to make a clone (single or multiple i.e. multi-SIM).
Could the different versions of Algo be implemented into a singl card - is the question of sufficient space for the code, i.e. - theoretically no problem.

2. About "several' years.. i consider myself as a realist, not an optimist.
No chance to the "soft" resolution - only "hard" (i.e. extremely highcost penetration into the "crystal" for the code and Ki extraction).

Thanks - meaning: using "cards of today" will not be usable because of lacking the appropriate algo ...

Thanks - I assume that this fact might also be an explanation that 12in1 was replaced by 6in1 - just because more/higher algo needs more space and space inside multicards is limited ...

I would not exclude that it could be one day either by helps of "social engineering" that leads to a leakage of "prominent position" - or by someone who worked at such an enterprise and takes the info out to damage the former employer ... or is the card constructed that extraction of algo and Ki is theoretically impossible without destroying the chip?

Hi
I have a question...
If I have Ki code of my sim card(comp128 v2/v3) could I clone it?

How did you get the KI code?

Does it really matter how he got it?
