Caller ID spoofing

Caller ID spoofing is the practice of causing the telephone network to display a number on the recipient's caller ID display which is not that of the actual originating station; the term is commonly used to describe situations in which the motivation is considered nefarious by the speaker. Just as e-mail spoofing can make it appear that a message came from any e-mail address the sender chooses, caller ID spoofing can make a call appear to have come from any phone number the caller wishes. Because of the high trust people have tended to have in the caller id system, spoofing can call the system's value into question.

Nokia ImageShack

In Nokia phones to tilt the screen image by 90,180,270,360 degrees use the following codes

"*#5511#" by 90 degrees

"*#5512#"by 180 degrees

"*#5513#"by 270 degrees

"*#5514#"by 360 degrees

when the call is connected a pre-recorded voice asks to enter the mobile number
then press the mobile number of whom you want to know the credit.
then it asks for pin,then just enter "1234".

Hacking Caller ID: unblocking blocked phone numbers

At The Last HOPE hacker conference, Kevin Mitnick, arguably the most famous hacker of all, demonstrated how call blocking can be hacked, and the hidden phone number exposed.

The hack starts with a VoIP telephone number. Mitnick uses Flowroute as his provider, but he told me afterwards that the same thing can also be accomplished with a few other VoIP providers.

Kevin Mitnick speaking at The Last HOPE conference

He starts by forwarding calls to an Asterisk server that he maintains.

According to Wikipedia, "Asterisk is an open source/free software implementation of a telephone private branch exchange (PBX)". The Asterisk website says it runs on GNU/Linux, OpenBSD, FreeBSD, and Mac OS X. On the hardware side, all you need is a computer to use Asterisk with VoIP calls (to interface with the public telephone network requires additional hardware). In other words, it's not an expensive thing to set up.

Asterisk has its own scripting language. Once a phone call hits Mitnick's Asterisk server, a script that he demonstrated analyzes information in the SIP header. The script can see the originating phone number and can also tell that the caller wanted their number hidden. But, just because you ask for something doesn't mean you'll always get it.

Mitnick's script forwards all calls to his cellphone. But, calls that requested privacy have an arbitrary three digit code pre-pended to the phone number. The net effect is that, when Mitnick's cellphone rings, he not only sees the callers' phone number, he can also tell that they tried to hide it.

The basic issue, as I see it, is that once telephone calls become computer data, they can be manipulated like any other type of data.

Caller ID can be hacked in other ways too. In June 2007, Good Morning America did a story on Caller ID spoofing. That is, calling from one phone number but making it appear that you called from another number. Mitnick briefly appeared in that story which is available on YouTube.
