Hi guys,
Just wondering, what do you feel about GSM security? Do you think that mobile traffic is really secure, there are no loopholes?

Nothing connected to a network is really secure - there will always be exploits.

No.

GSM security is flawed, the A5 (both A5/1 and A5/2) algorithm used in GSM has been broken, and there is a way to clone SIMs as well. The new A5/3 version of the encryption is somewhat more secure, but still breakable... In other words, GMS is protected agains casual eavesdroping, and that's as far as it goes.

Here are some interesing resources:
