Clever Caller ID Tricks With VoIP

Posted by timothy on from the making-the-most-of-the-line dept.

An anonymous reader writes "securityfocus.com has an interesting article collecting some clever exploits for VoIP. According to the article, using 'the open-source Linux-based PBX software Asterisk, used in combination with a permissive VoIP provider' can be used to fool caller id, and even get caller numbers that are supposed to be private."

    so is voip going to turn into something like the email spam mess once the peddlers of Mydixaflopin and their cronies start figuring out how to use it?

    The article states something of this kind: a 21 year old 'hacker' (quotes are mine) used VOIP line and a Linux based program named Asterisk to unveil blocked phone numbers and spoof his number. - well, that proves it, Linux is evil.

    Seriosly though, the only reason this is a problems is due to the fact that the VOIP providers are sending too much information to the end user and relying on the users' software to not reveal the caller's number.

    Clearly Linux causes invasion of privacy.

    So what?

    I should point out that it is possible to set your caller ID to 5318008. It was fun on an inverted calculator and I don't see how inverted caller ID is any different.
