Another Caller ID Spoofing Operation Opens Its Doors

from the not-just-for-annoying-pranks dept

Remember a couple months back when someone tried to set up a business for collections agencies letting them spoof their caller ID? This was the same business that quickly shut down when the owner claimed he received death threats concerning the business. Well, now, with a bit more anonymity, another company is offering a similar service — but this one (for a price) is open to anyone, not just collections agencies and private investigators. While this is mostly just used for pranks, it could have more serious consequences. As the article notes, some cell phones from T-Mobile use the caller ID to let you into your voicemail without a password — a setting that many people leave on by default. Another potential misuse of such a system could be to jump on VoIP systems. A few companies are now coming out with bridge devices that let mobile phone subscribers call into their home VoIP system. The system recognizes the caller ID and gives the caller an outgoing dialtone, so they can make international calls on their mobile phones at VoIP prices. If you know the VoIP number and the mobile phone number of someone who has such a system, you could spoof their VoIP system into letting you make all the calls you wanted… on their bill.

Not sure about that

It seems to me your other misuse wouldn’t quite work properly (with the current spoofing technology). It would seem to me that the bridging device would look for incoming wireless calls and the caller ID info there. That would mean a hacked cell phone (not such an improbable thing).

However the current systems use a fixed line to call you and the intended phone number, but the spoofing occurs in the middle, not on your phone.

Anyway, its a good point from a cell phone hacking point of view.
