The Palm like tool of hacker (VII): telephony and phreaking
We follow with this series of articles on the Palm like tools of hacking, centering in this case in the telephony and the Phreaking to us.
Phreaking is a term coined in the computer science subculture to denominate the activity of those individuals that orient their studies and leisure towards the learning and understanding of the operation of telephones of diverse nature, technologies of telecommunications, operation of telephone companies, systems which they compose a wire net and finally; applied electronics to telephone systems.
The goal of phreakers is generally to meet intellectual challenges of increasing complexity reacted with security incidences or failures in the telephone systems that allow them to obtain nonaccessible privileges of legal form.
The term “Phreak” is a conjunction of the words phone (telephone in English) and freak (monster in English). Also one talks about to the use of several frequencies of audio manipulating a telephone system, since the word phreak is pronounced of form similar to frequency (frequency).
Phreak is a closely tie discipline with hacking conventional. Auque often is considered and categorisen like computer science a specific type of hacking: hacking oriented to the telephony and closely tie with the electronics, in fact phreaking is the germ of hacking since the telephone system is previous to the extension of computer science at popular level, hacking arose from the contact of phreakers with the first personal computer science systems and communications networks.
Many tools of phreaking and telephony for our Palm exist generally:
- DigiDialer is a telephone marker DTMF (marking by tones) for our Palm. Simply we must approach the Palm the earpiece of the telephone, and through loudspeaker it will emit the tones necessary to dial the number that we want. This avoids to us to have to key we the number, not even to remember it. The program allows to concern the telephone numbers of the list of Contacts of the Palm.

- Similar to the previous one, DTMF GIVES is a Desktop Accesory to generate tones DTMF to realise telephone calls.
- War dialing or wardialing is a method to scan automatically telephone numbers using a modem, normally calling to each number in a local area to discover what computers or faxes it has available. Then it is tried to accede to them guessing the passwords. The name of this technique makes reference to the film of 1983 Games military, where the protagonist used her computer to call to each telephone of Sunnyvale, California, looking for other computers. A program for PalmOS exists, TBA that will serve to us if our Palm is connected to a modem. For other systems many programs of wardialing exist. For PC the famous THC-Scan program exists, of which I have found a tutorial in video.
- Spoofing, in terms of security of networks, makes reference to the use of techniques of suplantación of identity generally with malicious uses or investigation. SMS Spoof sends messages SMS modifying the telephone number of the sender, doing so it seems that the message has been sent from this other number.

- A Network Box is an apparatus that simulates the inserted salary currencies on a pay telephone, emitting certain sounds that the telephone interprets. RedPalm is a Network Canadian Box that generates tones of the currencies “to quarter”, “tell me” and “nickel”. This application requires to also install cbasPad, a BASIC interpreter. The source code is really very simple.
- You make a draft Extra is a program for telephones Kyocera and Treo to control the telephone cost approximately, and to obtain interesting statistics of the use.

- Smorse (Simple Morse code to sender) sends Morse code through loudspeaker of the Palm to 1-80 words per minute. At more speed it is not possible due to the limit of 10 milliseconds of resolution of the internal loudspeaker.
- Like curiosity, although related to telephony (at least the traditional one) RJ45 it is not a small program for Palm that shows the ways to finish a network cable we are going when it to crimpar: direct (host to hub) and cruzado (host to host).
Everything a world the one of phreaking, and as always, a world transferable to our Palm. In next post we will see the last chapter of this series of posts dedicated to how using the Palm like tool of hacking.

The programita of the RJ45 used in my HandSpring Viewfinder when it was that way going to mount, networks, walks that it did not remove to me from more from a mess the aforesaid one!
What wonder of post Marks, did not know the one to me of spoofing of the SMS
Thank you very much They went, I am glad of which it has surprised to you with some
It is fundamental to by hand take the scheme of the network cable, although you make thousand cables, soon to the weeks already you have forgotten the order.
