Caller-ID Spoofing for the rest of us

November 22, 2004 by in Tech with 8 Comments

Thanks to Camophone.com, now you can make calls anywhere to the United States and you are in control of the Caller ID that is sent to whoever you are calling. You can have the number of the White House switchboard (202-456-1414), how about Michael Eisner (Chairman of Disney – 818-560-5151) or just about anyone else you can think of.

I have tried the service, it is CHEAP, and works! Pros: they only take payments via PayPal. However there is one MAJOR problem: With this Caller-ID spoofing service, mimicking a persons number, you can gain access to a cellphone voicemail box that is set to read caller ID and grant access without a password. Virtually all major carriers are vulnerable to this flaw.

    I’ve never researched how callerid works before, but I’ve always assumed it was spoofable.
    I’m surprised to hear that there are voicemail services that take that callerid info as authentication.
    I guess I’d have to know more about callerid, but I’d suspect the problem isn’t with this service, it’s with the voicemail systems using this not-intended-to-be-secure piece of info for authentication.
    But hey, maybe I’m totally wrong and callerid was meant to be secure and unspoofable from the beginning.

    Um. CallerID spoofing will not get around most cell phone security. Cell phone companies will look at the ANI (automatic number identification) instead of the CallerID. Caller ID is easily spoofed using a PRI Circuit.

    Not sure why people are paying for this service. This CallerID spoofing was shown by Kevin Mitnick on live television a while back on The Screen Savers on TechTV. Although he did not/could not provide exactly what he had dialed before the phone number; he said it is not that hard to find out how to do this spoof by doing a little research on the Internet.

    just google “orange box”

    For all you that didn’t know, Kevin Mitnick did this by dialing into a PBX that was set to display a different outgoing number (look it up, it is possible) and then dialed out of that and to Leo’s cell. Because he was using the PBX’s dial-tone, it displayed his number as whatever number was programmed into the PBX (in this case his acomplice programmed it to be the White House).
