Gilad, I expected better from you (being the one who built an SMS gateway from recycled paper and used cardboard boxes). Spoofing != sniffing. Spoofing is actually much easier. Faking the GSM number you *send* to someone is easy/ier (I just have to fake the proper SMS message). Sniffing the SMS your bank sends *you* is harder. > can just as well break into > your phisical location and take what he wants or kidnap the children of > the sysadmin or any other large scale operations such as those. That's actually easier than spoofing and/or sniffing (proof: statistically. Look how many people are in jail for kidnapping, and how many for spoofing/sniffing. QED). > It all > depends on what you are protecting.

I tried to give Omer real practical advise when suddenly the conversation drifted into GSM phones and kidnapping kids.
