--=] National Security Anarchists [=-- --=] Volume I, Issue IV [=-- --=] Date Released: 8/14/91 [=-- == NSA Editorial == Welcome to National Security Anarchists Issue 4. Yes we at NSA do admit this Issue has taken some time since our previous releases. Not to worry NSA is still in existence and we shall continue always. Why for the delay, Muds. Trust me, Muds eats Hackers. If you are planning to play muds, Rest assured that you best say bye bye to your Hacking Career. As I type this Introduction, Dead Addict is blabbing "Dick Van Dyke, Starring Dick Van Dyke". And has raised an interesting question. Why do these old shows have separate beds for the Married Coupled. And also these Married Couples have Children?!? Many of you have raised a point that is obvious. We copy our material from books/trash/manuals. Yes we do and we always have admitted it. Our Motto states "Plagiarism is the Basis of Creativity". Why do we copy straight from the manuals/trash? Simple! The best source of Information is from the Source. Here is a simple analogy to explain it even more. Information is a juicy Steak. And Most groups take this information and reword it. Thus this is Second Hand teaching, and plus you are learning what they learned. Therefore that is in comparison to chewing up a steak and feeding you tasteless bits. Now we at NSA give you that Steak, unchewed, unprocessed, so you to can enjoy that same flavor that we experience when examining this material. Also many of our readers have made several interesting ideas and comments for the newsletter. Now The Serious Side of Hacking is available in this Newsletter. What is The Serious Side of Hacking, well let I'll let Dead Addict explain his section. NSA has released SlimJim Version 1.0 into the Hack/Phreak world. SlimJim is a Unix Utility for MS/DOS machines. SlimJim slims those large password files and makes them smaller. Plus SlimJim is very fast even on IBM XT compatible computers, and saves you space at the same time. SlimJim can be found on various Hack/Phreak boards. Soon Silicon Slave Version 2.0 will be released. Yes, another Hack/Phreak utility from NSA. Silicon Slave is a collection of common Hack/Phreak utilities incorporated into one program. Details will be released later. ___Your Editor___ Mind Rape ------------------------------------------------------------------------------- Table of Contents Section Subjects -------- ------------------------------------------------------------------- 4.0 NSA Editorial 4.1 Table of Contents % 4.2 Anti-Pirate Video Techniques/GTE Project 358 4.3 The Challenge of the Industries <Submission> % 4.4 405MB Optical Line Terminating Multiplexer Glossary % 4.5 Human Speech Understanding/GTE Project 426 4.6 VMB Shuffle <Submission> 4.7 Serious Side of Hacking 4.8 Info World 4.9 NSA Information % - If you are not an authorized USWest/GTE/AT&T/MCI/SPRINT/NEC Employee, you are not permitted to read this information.

Emphasis was placed on development of hardware and software to demonstrate the feasibility of network-based copyright protection. Figure 358-1 depicts VCS functional blocks. The copyright protection scheme encrypts video material by scrambling each vertical field and embedding program serial number, field number, and error correction codes in one horizontal line of the vertical blanking interval (VBI). Public domain encryption techniques are used to recover 15-bit pseudo-random descrambling codes. Decryption requires the keys(s) provided by a remote database, accessed through a low-speed communication link (telephone network). This allows viewing control and revenue collection by intelligence in the remote database, but facilitates copying and distribution of protected material. The encryption scheme has two levels, one for protection of video descrambling codes embedded in the VBI, and one for protection of messages between the home and the remote database. The encryption technique assumes the potential pirate knows the encryption algorithm and demonstrates years of work time to decrypt protected material without database-controlled keys. The copyright protection scheme provides high-integrity protection of video material until the key(s) is released, which provides security for live broadcast and/or the recording and distribution phase of video cassettes. While there are various schemes for protecting decrypted material from copying during viewing, including locating the decryption function inside a special TV or video monitor, none of the schemes provides significant protection from the sophisticated pirate. --------------------------------- == Figure 358-1 == == Viewing Control System = --------------------------------- Clocks Phase Locked Analog Subsystem to Hortzontal Rate __________ /--------------\----1.007 MHz Clk------------------------------>/ \ | GenLock |----503.5 kHz Clk------------------------------>| MC6859 | | Video Timing |----2.014 Mhz Clk--->/-----------------\ | | | Recovery |----Vert Drive------>| | | Data | |--------------|----Hor Blanking---->| |PA7-PA0 | Security | | | | MC68HC05 |------->| Device | | VBI | | |PC7-PC0 | | | Detection |<------------------->| Microcomputer |------->| (DES) | | Insertion | | Unit | \__________/ |______________| | | | | PA7-PA0 | (MCU) | | Descramble/ |<--------------------| |PA7-PA0/-----------\ | Scramble |<--------------------| |<----->| On | | | PB7-PB1 | |PB7-PB0| Screen | \______________/ 15-Bit \_________________/------>| Prompts | ^ ^ Descramble/Scramble | | \___________/ | | Control | | | | \_/ \_/ VCR | RS-232 Port | TV This project supports the implementation of a small field-deployable viewing control-copyright protection system. Results will be used as building blocks to define a viewing control field demonstration for the Cerritos ][ testbed. The past year has seen the development for VCS of MCU software that is modular for flexibility during further development, yet does not exhaust the capacity of the Motorola 6805 microcontroller and is able to operate within the bounds of visual field time. VCS processing in the microcontroller of the Home Unit is now able to serve three levels of message encryption and apply up to five scrambling keys to each video program. It can also handle midtape video start, viewing time control, and session cancellation. Developments of message overlays and application of "anti-pirate" copy signatures are now under way and are scheduled for completion in the 1991's. A significant effort during 1990 was the design and implementation of a unique scheme for generating robust scrambling codes that preserve the smoothness of the presentation. The method is based upon encryption of successive field numbers. It produces scrambling codes that are uniformly distributed and unpredictable, hence largely pirate-proof, yet can be easily recovered by the system when videotape flaws prevent reading of field numbers from the tape itself. Six patents were filed on viewing control system techniques during the year. Preliminary meeting were held with three studios, one TV manufacturer, and one anti-taping technology company. A presentation was also made to the T3 Standards Committee. This project also supports activities relating to standards, including attendance at T1Y1 and HDTV groups, as well as the EIA Multiport Receiver Group. A North American standard for compressing digitized video is under active investigation by the T1Y1.1 Experts Group on DS3 TV. GTE Laboratories had increased activity in this field by attending the meetings held by the Experts Group. These meetings are usually attended by representatives of the T1Q5.5 Experts Group who are concerned with performance standards for digitized video transmission and represent the broadcasters and others. ------------------------------------------------------------------------------- --=] National Security Anarchists [=-- --=] Volume I, Issue IV [=-- --=] Presents [=-- == The Challenge of the Industries == == Dennis C. Hayes == == Speech at BellCore's CPE WorkShop == == Contributing Writer == == Mobius Drux == Below is a capture from HAYES, it is from the President of Hayes speaking on the future of ISDN. Hey, folks this is the future so it would be to your advantage to at least know whats going on. "Waiting for ISDN to Happen..." That phrase is a phrase that is seen often -- in magazines we read -- in speeches we hear or in meetings we attend. "When will ISDN happen?" Our market and product planning departments ask. Our customers ask. The analysts and media make their predictions. In the last two years, the magazine articles and speeches are changing: something has happened. In the last year people are now questioning "WILL ISDN ever happen?" As for the question, "Will ISDN ever happen?", we all know the answer is yes. ISDN will happen and ISDN is happening. The countries in North America cannot afford to allow our communications services to be incompatible or non-competitive with communications services used by our companies' and America's global competitors. ISDN is happening in Europe and is beginning in Asia and our region of the world cannot afford to be left out. ISDN must happen in North America. But there is a perception problem and the members of our computer and telecommunications industries must solve the problems that still inhibit the commercialization of ISDN. If we were to graph the public interest in ISDN, we would see a "Spike of Expectation" during 1986 - 1987 -- even into 1988. People believed that ISDN would make an impact on businesses and were excited about the possibilities of using this technology. But when the expectations were not met, excitement was followed by a "Valley of Disappointment." We must begin building the excitement again -- but at a realistic level of steady growth -- where the public interest matches the industry's capability. A steady growth of capability over the next year or two will rebuild confidence. We must provide concrete and tangible evidence of this steady growth of ISDN deployment on an ongoing basis. Keep in mind the person who has to make the decision to buy the service. What makes the MIS Manager or Telecommunications Manager buy the service and products that implement ISDN? What makes them convince the CIO that ISDN is worth the investment? The COS (Corporation for Open Systems) announcement about ISDN 1 has rekindled public interest and is a step in the right direction, but we and all of our colleagues in the industry must remove the real and perceived barriers to successful commercialization. Part of the problem that caused the "Valley of Disappointment" comes simply from the concept of time in the computer industry being so different from the concept of time in the telecommunications industry. The computer industry: predominantly data oriented -- and not regulated. People expect computer technology to change rapidly and it usually does. It is much easier for the computer industry to develop new products because they do not face the barriers that the telecommunications industry faces. Look at local area networking. It took several years but it was fairly easy for the computer industry to bring that technology into businesses. LANs were market and technology-driven applications that faced no regulatory barriers. The telephone industry, on the other hand, is a much older industry that is affected by a number of restraints which throttle change: compatibility with the existing network and the federal and state regulatory barriers -- just to name two. The telephone industry's roots are with voice services to residential customers even though data traffic is rapidly growing. There is less understanding of data services and very little understanding of the integration of voice and data by most employees in North American telephone companies. So the two different cultures must meet. And ISDN needs to bring the merger of these two industries together very quickly. ISDN is causing a tighter coupling, tighter integration -- particularly with the integration of voice and data -- making computers and telecommunications come together faster. But as we all know -- there are barriers we face. In March 1988, I gave a speech for an ISDN User's Group here in Atlanta on "Removing the Barriers to ISDN." I am sure that many of you have heard or have made a similar speech: All of us must work to overcome the barriers, from those in the industry who provide the service and equipment to the customers who use the service and buy the products. It is our job to motivate the customers. ISDN is being limited. Limited by service availability, the regulatory environment, tariffs, incompatibility between products, complexity of provisioning and installation, and knowledge about deployment -- just to name a few of the barriers. Deployment plans and capital budget are crucial elements that throttle the retooling of the telephone company workforce. Service providers must rethink the way they develop and deploy technology. If they want to play an increasing role in the rapidly growing data market, the telephone companies will learn to think of central offices as "data centers." CPE vendors must evaluate and revise the way they develop and provide equipment to users, as well as the way the applications get implemented to use the service. And as we begin to break down these barriers we must focus on our customers' needs, keeping in mind the person who has to make the decision to buy the service and equipment. We must offer the service and products that make communications more efficient and cost effective, and that give the user a competitive advantage in his business. But, how can we expect a customer to implement ISDN today? We make it difficult for the MIS Manager or Telecommunications Manager to buy the service and our products. An MIS Director cannot plan a nation-wide or global network for their company because he cannot easily determine where service is available now -- and more importantly when service will be deployed during his planning horizon. And, there is no direct single place to go to find the answer. Very few user companies are US-based only. And certainly very few companies are based only in one service area. So an MIS Director is faced with going to a multitude of sources to collect data just to evaluate if ISDN is a viable technology for an important application and no one can tell him where to find all the needed information. People in the communications business must communicate and share information. With the two industries working together we can leverage our technical expertise to benefit our customers. ISDN is technically successful and working today even though improvements will be made as standards evolve. What is needed now is the ability for cooperative competition to allow the successful commercialization in the North American markets. Customer needs can be met by cooperative behavior between competitors which will remove real or perceived barriers that the customer faces. The Japanese understand cooperative competition. Look at the development of the VHS tape player. The modem industry understands cooperative competition. The development of CCITT V.42bis is an example of cooperative competition, where companies worked together to offer the public the best technical solution for compression in modems. It is time to ask our legal departments how we can work together rather than allowing them to say that we can't. There are areas such as standards, sharing information with customers, and removing the barriers where we can legally work together without crossing the line into areas where we compete for business. ISDN commercialization takes a great deal of team work from all of us: Service Providers; Switch Vendors; CPE Vendors; Applications Developers; Resellers. And, we must always be focusing on the end user and their needs. Our goal as an industry should be to provide total customer satisfaction -- which will mean offering a range of solutions. Some of the visionary people in the two industries believe that fiber optics and broadband ISDN are the future. Basic Rate Access (BRA) and Primary Rate Access (PRA) have their places. BRA can offer a range of applications that can create the desktop telecomputing environment that starts the shift from the paper-based office to one that is electronically-based. Today the Xerox copier and the fax machine support the paper-based office. Basic Rate ISDN is the technology which can initiate a wide-area change in multiple locations and to electronic-based communications. Trends show that businesses are changing. They need to be more competitive in the global marketplace. They require a shorter cycle time from decision making to implementation and they can no longer act as a single unit. A business must work together with multiple enterprises. ISDN can be a major catalyst that transforms businesses today and brings people into the equation. I believe that the integrated services and performance of ISDN will fundamentally change the way people and businesses communicate. ISDN is not a faster modem. It is not a "nicer" telephone. It is not easier wide-area, dial-up switched 56K digital circuit and packet communications. It is the combination of these things offered economically, worldwide, that are the ingredients for an "office revolution" and a new market for all of our industries. ISDN can fuel the transition to an electronically-based office. Things are happening in the computer industry -- large screen workstations from companies such as Sun, HP, DEC, Apple and IBM. Applications like IBM Office Vision, AT&T's Rhapsody, and Lotus Notes. Workstations are no longer for "data" processing -- they are for information processing and with the integration of voice and data, information processing can be brought to a new level of interaction between the people who make decisions and take action based on the information. I am sure when the copier was first developed, no one imagined how businesses would change -- with the ability of the printing press at their immediate disposal. We in the ISDN industry can just begin to think about what can happen with true multimedia integration. With voice and data integration, people will be able to work on documents together -- no matter where they are located. Much of my company's focus has been on developing products that provide the platform for good integration of voice and data --- not just products for voice -- or products for data. And, we realize the importance of applications developers, the people who understand how work is done in an insurance company, a transportation company, a retailer, or manufacturing company. These are the people that have to drive the implementation of applications for the end user and can assist us in exploring the integration of voice and data. We need those people who understand the way businesses work to develop the applications needed by real users who don't yet know how multimedia integration can change their ability to get work done. We have developed PC adapters for the computer to work with the service and we have focused on the program interfaces (the Hayes Standard AT Command Set for ISDN and the Hayes ISDNBIOS). These interfaces give applications developers a platform to write their programs and provide the connection between the CPE and the computer. We strongly believe that it is the applications that will make customers want to use any service. ISDN will be successfully implemented only when our customers perceive it as faster and better, and offering improved price performance and giving them some real advantage over their existing telecom and datacom solutions. ISDN must allow our customers to meet their needs of today but also allow them to take a large step forward in doing difficult tasks more easily. ISDN must provide reasonably priced applications that are not readily available today with alternative or bypass communications solutions. Our challenge is to bring our two industries together and to make ISDN happen. To remove the barriers. Don't just create another spike of expectation and excitement. This afternoon the computer industry has an incredible opportunity -- the opportunity to work together with the telecommunications industry to make ISDN happen. For CPE vendors, applications developers, switch manufacturers and telecommunications service providers to work together to launch a new technology which will bring competitive advantage to our North American customers, and fulfill user needs for easily accessed, integrated, efficient, and cost effective integrated communications. A simple concept: customers and suppliers working together letting each other know what they need to make something happen. Bellcore has given both industries this workshop to begin the talks and to open the lines of discussion between the two industries. And, going forward, they will continue to play this role through their Resource Personnel. Together the two industries can make ISDN a reality. Just as we heard for six or seven years "This is the year of the LAN" announced by our or another of the LAN company's CEO's, there were six or seven years of the LAN leading to the success we see today. Today's LAN is an important business tool. If we grasp the opportunity Bellcore has given the industry here today on top of all that is already being done throughout the industry, then surely we will be able to look back and say 1991 was the first year we claim "This is the year of ISDN." _ _ _ __ ' ) ) ) / / ) / / / ____/___o . . _ / / __ . . _., / ' (_(_) /_) <__(_/_/_) o o /__/_/ (_(_/_/ /\_ - A MD 20/20 production for the continued Pursuit of FREEDOM of COMPUTER INFORMATION (c) Copy-It-Right ------------------------------- ------------------------------------------------------------------------------- --=] National Security Anarchists [=-- --=] Volume I, Issue IV [=-- --=] Presents [=-- == 405MB Optical Line Terminating Multiplexer == == Glossary == This section explains the basic terminology used for operation/maintenance of the FD-39001A O-LTM.

In addition, substantial support was provided to GTE Airfone, and research was also directed at understanding how factors associated with wireless communication (e.g., time delays, low-bit-rate speech coders, various channel impairments) can influence conversations. In 1990, Project 426 continued to support Project 533 (Application of Automatic Speech Recognition to Telephone Operations) by providing information on the characteristics of calls to Customer Service Order Centers (CSOCs). Project staff completed analysis of a large set of conversations have been cataloged on a variety of dimensions. Based on the information in the database, a report was prepared on automating customer service contacts by means of computer-based speech recognition. In addition, work has started on characterizing vocabulary in different types of conversations (e.g., orders to install versus disconnect service) via automatic indexing and cluster analysis. To support detailed analysis of these recorded conversations, the VAX speech editor was rewritten using a C++ style object-oriented user interface. A study to analyze the timing of question-answer sequences between CSOC representatives and customers is now under way. The long-term issues pertinent to the development of speech-based automated systems were addressed in a paper presented at an international conference. Topics discussed included methods for measuring the complexity of dialogue, convergence (the process by which conversant adopt aspect of each others speech), and the use of dialogue control acts (extra conversational steps that ensure that the conversation proceeds smoothly). Project staff also completed a report on an experiment performed in 1989 that was designed to investigate the effects of attentional constraints on the processing of natural and synthetic speech. In 1990, work continued on evaluating conversations recorded under controlled conditions that simulated one or more factors found in mobile telecommunication systems. A new test procedure designed in 1989 was refined, and measurement techniques were developed. Using this new procedure, an experiment to investigate conversation dynamics over delay circuits with 600 and 1200 ms lags was completed. Resolving the delay question is an important first step in the project's investigations of conversation dynamics in wireless channels because speech-compression techniques can introduce a delay on the order of 150 ms (delays due to switching or transmission may add significantly to this figure). The project team is now in the process of testing subjects in a second study that includes speech coder/bit error conditions using the two-way ASET board developed by the Speech Technology Group. Work in support of the second-generation Airfone system focused on the design and operation of Seatfone ][. In 1990, project staff completed a series of experiments and reports, including a study on user preference for membrane keypads, a study of dialing performance using membrane keypads under different feedback conditions (both auditory and visual), an assessment of a new Seatfone handset, detailed comments and suggestions on a set of flow charts intended to illustrate the call-sequence logic of Seatfone ][, and a report on the quality of new speech prompts. In addition, work has now started on a comprehensive evaluation of the Seatfone ][ design using a prototype developed by Airfone and ASIC Designs, and on the preparation of detailed user-interface specifications. ------------------------------------------------------------------------------- --=] National Security Anarchists [=-- --=] Volume I, Issue IV [=-- --=] Presents [=-- == VMB Shuffle == == Contributing Writer == == Mobius Drux == This Phile is hopefully the first in a series of Philes on VMB's. This is also dedicated to Night Stalker (.aka. Flt 255 of (313) in memory of..) , and all the fellows at NSA and Disconnected, including but not limited to those who have helped, Dark Druid, I-Shence-Master, Mind Rape, A.O.D., Dead Addict and Mommie Dearest. I would like to add that all this information contained here within is not intended to cause, direct or in any means relate to any illegal activities. I can also say the following is true. Title 18 of the United States Code, Section 1030, (Revised 1986) gives the Secret Service, among other Federal law enforcement agencies, the right to investigate fraud and related activities in connection with "Federal-Interest computers." --------------------------------------------------------------------------- - The above is true and the information below is for educational purposes - - only. Plus the information should be free to all! - =========================================================================== 8.8.91 VMB Number 1.00 A Info Series on 800.xxx.6245 MAIL Scans =========================================================================== The purpose of this Phile was to Scan the 800.xxx6245, where xxx is all the possible prefixes. 6245 represents MAIL on DMTF fones. So I realized that many people would take the time to check out this sub-prefix, 6245. I have done all the initial information scanning and did not try to invade these systems. I hope this information will help you to better understand VMB's. Heck if you don't know what a VMB is you should do a little research. I believe LOL #10 or 12 is on VMB's. I will however cover some basics. VMB - stands for Voice Mail(Message) Box, this is a voice message system, that allows messages, call transfers. ect. - Most work on a 3 or 4 digit mail box and an associated password to access that box. The problem is alot of systems are getting security wacko and have Password, then Box or 8 digit boxes and 8 digits Passwords combos. This phile is not meant for you to hack these numbers but just as an informational source. As an Anarchist or CyberPhreak you can appreciate the wealth of this information. These Corporations generally do not take the time to listen. I really doubt if they even use there VMB's, however if you have a gripe leave a message to those concerned. ======================================================================== -------- Doing The VMB Shuffle or How to spend a Summer Day ----------- ------------------------------------------------------------------------ [A] FH (Fuckin Hacker) 2.0 - Modifications and Setups that were used. [1] Main Menu , Type D for Utilities [2] Type A for Config Modem Suggest putting ATL0 or ATL1 in your Modem Initialization string to turn the speaker low. [D] PBX Dialing - Turn to YES [E] Outgoing Digit - Set to 1800 [I] Speaker - ON [3] Go to the Target and Valid files and leave only one entry, you can delete all the entries, it will leave one that is set at default values. [4] Go next to EDIT EXTENDERS Remember this is a VMB run so you need no extenders, but will Add new ones. Choose ADD. [A] None leave blank [B] None leave blank - The PBX option in the config modem takes care of the outdial digits. [C] Leave at Local [D] Adjust to your board or leave as defaults. [E] Adjust to your board or leave as defaults [F] leave off [G] Answer Delay - set to 0 [H] Target Delay - set to 35 or more [I] 0 [J] Code First - YES [K] Sequential - I use sequential so I can watch when the cycle ends and ESC back and flag ones that completed off or read just the scan to the next prefix series. [L] Code Length - 7 [M] Code Template - ##abbbb where ## is the Digit Cycle, a is the change cycle and bbbb in this case was 6245. (Mail). I use a random scan search for example I know that the first two digits of a prefix cannot be 1 or 2 and the third cannot be 0, so I set up my ADDs in a random number sequence to cover the numbers from 2 to 9, ie. 8,2,9,5,7,3,6,4 so the first template is 82X6245 then 22X6245 then 92X6245. The X is important since this is what changes from scan to scan. FH doesn't go in order and may hit an code sequence two or three times so you may hit an prefix once every 15 dials. [N] Starting Code - ##abbbb where # is your starting number ie 82, a is always 1 on the initial pass and increases, bbbb in this case is 6245. All other values I leave at default, once I have added the prefixes, I go to the extender flagging and flag them all. [5] Flag Extenders - flag all your additions [6] ESC and start HACKING from the main menu. I may add that I created a batch file that would random hack and wait for 5 - 15 minutes both ways. Do not spend 8 hours or even more than 30 minutes Scanning even if you have alot of Ports, running. ------------------ FH VMB Hints and Thins to Watch For. --------------- [B] Pay Attention here. Alot of people miss these hints, they will save you time and will even force you to listen durin scanning. You hear a click before the ringing, this is 99% a invalid prefix, prepare to hit the SpaceBar to skip this prefix. You here a dial tone, hey this may be a PBX, let us know! If you hear some DMFT tones then another ringing, this may be a Diverter. You get a message to leave a message, Hit * or # if it continues wait for a double beep. This can be a diverter or a backdoor into a PBX or you can just playback the messages or other stuff. You get a Carrier, fast hit spacebar record the number. In the setup I have provided FH may error out because of no Code File stated. Check the Carrier later. VMBing works best at night, after business hours, since most companies have operators during the day, and you will miss and piss off people during the daytime. Be careful of the MCI/US Sprint lines, they have Level D ANI and see a display of who called. If they have CA (Call Accounting) then they have a record of your number on a printout (Sweep Finder). Most Passwords can be the box number or an variation, for boxes try either 999,9999,1000 or 1111 these are generally the default Telco administrator boxes. These are just a few notes...Now for the Good stuff. Remember, These numbers are current as of 8.8.91 so they are fresh, don't burn them out. If you do get a Slave going let me know. If there are any additions or comments let me know.

Poetic hackers are perhaps one of the most neglected minorities in the country. Looking on a list of possible scholarships, I see "Homosexual, Blind, Black Agraphobes", but no poetic hacker. Lets face it, society just ignores us. Fellow hackers just ignore us. No more. Now we have an entire dedicated section in the most prestigious hacking newsletter (that has my name on it) ever produced. Now, why me, why not our capable editor Mind Rape? Very good question... I was going to let him write this section... Then I heard some of his poetry. I handle this section now. (offence intended, Mind Rape). However, this is not only a poets forum, we also support many other neglected hacker topics. What topics you say? Lotsa topics.... Previously unreleased boxes, cool anarchy techniques, and much, much, more. Mind Rape wanted to call this area "Hacker Sarcasm". I said "ikes, that sucks, Mind Rape". But we tried to keep a humoristic view about it, and hopefully there will be a pinch of humor in all of this writing. Where to complain if you do not like any of this: fuck you, go to hell, lemme see you do better, you uncreative, unapreciative louse. (wow, that's pretty cool word too - "louse") Unclaimers, Reclaimers, Disclaimers, Recliners - I hereby claim every hacking technique ever to be discussed here WORKS. I don't know what the word RECLAIMERs means. The only DISCLAIMER this section has is that we take no responsibility for the MANY crimes we hope to encourage you, and your friends to commit. RECLINERS, great to laze around in. Ok, kids, that looks like about it for now.... enjoy the TSSOH articles contained herein (wow, what a cool word!), and Mind Rape, I sure hope to hell you don't want me to write an introduction EVERY issue.

This dear soul was kind enough to take me under his wing and show me some of his incredible inventions. Luckily for all of us he was not only interested in saving some money (he too abhors the idea of paying for ANY phone call), but had a healthy interest in anarchy as well. The INVISIBLE box I am about to describe is SO incredible it makes the blotto box look like the DONUTHIN box (to be released at a later time in this series). DISCLAIMER: Important! This file was DESIGNED to ENCOURAGE others to break laws, commit anarchy, and create havoc. If you have NO intention of doing all of the above please do NOT read this. I however will take NO responsibility for the MANY laws I hope I to encourage you to break. USAGE: Essentially this is an improved blotto box. But the blotto box, as we know was bullshit, this WORKS! (I have, um, er, friends that have told me so, I would NEVER break any laws myself). Through the use of the RS232 port on your 50mhz IBM compatible we will show you how to destroy ANY, I repeat ANY area code you wish to destroy. I know this sounds incredulous but there is an essential flaw in the surge protect system that is installed around the country. (This system is the reason that the blotto box did not work and was bullshit). One of the incredible features that this box has is that it is IMPOSSIBLE to trace with existing current technology. WHAT MAKES THIS BOX POSSIBLE: The flaw with the infamous blotto box is that it tried to instantly fry the area code (another flaw is that it tried to kill the area code that you were IN). The INVISIBLE box slowly builds up voltage in the remote target until the required voltage is established, then discharches just enough voltage to create a spike to demolish an area code. MATERIALS NEEDED: Honda Generator: Note: (hey, WOW, they DID get SOMETHING right on that blotto bullshit) How to obtain: Rent (this costs a bit, so stay with me) Steal! (preferred method) 486 50mhz IBM Compatible: Why all this power? One of the reasons that this has not been done before is that there is not enough speed to properly kill off area codes with a wimply 486 25mhz, so we have to use a 50mhz machine. How to obtain: Again, NSA STRONGLY recommends that you steal one of these. (the chair-through-the-window-technique is suggested). !!!MOST IMPORTANT!!!! The National Security Anarchists Release Of "Area Sucking, Smashing Heroific Osculator: Lancaster Engineered" I know the title is a bit of a mouthful, but the writer of the program (my friend I was telling you about) insisted, so NSA finally gave in, and released it under that name. This program has already been released to the general public, and can be found on ANY worthwhile H/P/A/C/V/K/W board in the country. The interface between the components has been explained in detail with the docs to that accompany the program. (we tried to think of an acronym for the program, but were at a loss). Well I guess thats pretty much it. I would explain how to use the program, but it is SO painfully obvious once you load it in, I would feel like an idiot spending precious disk space explaining it here. NOTES: I would like to thank my friend (Lancaster) for thoughtfully engineering this, and taking the time and energy to write the program (he spent four LONG months doing so). I would also like to announce with pride that this program is now Windows compatible, and soon will be released for various other systems depending on the hardware that is currently available on some systems. Thank you, and happy area code killing.

Therefore resulting in the mixture of both, Info World. This is where one can develop a good source of knowledge of Teleco/Hacker Information. Here, one can see what new advancements have taken place/problems have happened in the Teleco/Hacker World. Also one can see and theorize how Ma Bell can use her new technology to destroy us. Even if the idea is petty, but expand on that idea. We do tell you our views so that hopefully Hackers/Phreakers will develop their own, be able to create their own views/theories. To create that realization for him/herself, which then creates a better understand of our Society and yourself. Do you limit your imagination... ------------------------------------------------------------------------------- ------------------------------------- == PAC Bell, NEC Sign SMDR Pact == == Telephony == ------------------------------------- Pacific Bell has inked an agreement to market NEC Technologies' Centrex-based station message detail recording (SMDR) and call accounting equipment to it's California Centrex customers. The additional products are expected to help make Pacific Bell's Centrex offering more attractive and competitive with customer premises-based network solutions. The NEC gear, known as Centrex Telemanagement, lets telecos offer call accounting, traffic management, automated directory, facilities management, and equipment and feature inventory through the central office. The equipment can interface with AT&Ts 5ESS and 1AESS switches, Northern Telecom's DMS-100, and NEC's own equipment, according to Susan Schneider, product marketing specialist with Boxborough, Mass. based NEC Technologies. ----------------------------------- == MCI Readies Data Platform == == Telephony == ----------------------------------- MCI has unveiled the platform that will bring its Virtual Private Data Services (VPDS) into the future, as well as the first offering via platform: a frame relay service. At the International Communication Association show in Anaheim, California, in the first week of June. MCI unveiled plans to deploy a nationwide, cell-based network platform to support next generation broadband data services under its VPDS umbrella. The first service offered on the platform, frame relay, will be available in the second quarter of 1992., according to Don Heath, MCI vice president for data marketing. The network also offers a migration path to future services, including switched multimegabit data service and asynchronous transfer mod-based broadband integrated services digital network, he said. "What MCI is offering is a clear migration path to tomorrow's communications networks," Heath said. "We're opening the door to make broadband ISDN services a reality." The broadband platform will be cell-based, using 53-byte, fixed-sized data packets. Initially, MCI will offer the data services on permanent virtual circuits. Later, MCI will offer switched virtual circuits, which will permit direct dial-up network with ISDN primary rate interface access. Network access will be offered at 56Kb/s, fractional T-1 and T-1 speeds; the backbone will operate at full T-1. ---------------------------------------- == AT&T Previews New Marine Cable == == Telephony == ---------------------------------------- AT&T Submarine Systems will introduce a new undersea cable product line at Telecom '91 in Geneva this October, the company said at the beginning of June. Known now as the SL2000 cable system, the product will be renamed, and a prototype exhibit will be on display at the show. Although AT&T will design, install and maintain the system, the company has been working with Kokusal Denshin Denwa of Japan for the past year to develop optical amplifier technology for the SL2000 according to Debra Guancione, product manager for AT&T Submarine Systems. Current underseas systems require repeaters every 20 mile to 60 miles. AT&T hopes to reach beyond 60 miles by the time the product becomes available for service in 1995. The cable system will package together bit rate-sensitive terminal equipment, dispersion-shifted fiber, optically amplified repeaters and cable, all configured according to customer requirements. It will offer rates of 5 Gb/s, 25 Gb/s or 622 Mb/s per fiber pair. ----------------------------------- == Motorola and Pactel Trial == == Telephony == ----------------------------------- Motorola and PacTel Corporation will conduct field tests and market trails of Code Division Multiple Access (CDMA) digital cellular technology. The trials will take place in PacTel Cellular's Southern California service area. The agreement follows more than a year and a half of CDMA testing already conducted by the two companies. Among the activities planned for the trial is the validation of Common Air Interface (CAI) specification. CDMA and TDMA represent two competing technologies designed for migrating cellular systems to a digital standard and increasing subscriber capacity. -------------------------------- == Teleport Opts for ISDN == == Telephony == -------------------------------- TC Systems, a subsidiary of the Telport Communications Group, is now providing local ISDN connectivity for Manhattan-based customers that need to maintain ISDN links with both Europe and the far Esat. The first customer to sign up for the new service is banking giant Citicorp, who will use it to establish connections with London, Brussels, Dusseldorf, and Singapore. TC Systems also operates one of the nations' largest ISDN "islands" consisting of over 6000 BRI liens, currently being used by its parent company Merill Lynch. ------------------------------------ == New York Tel Decentralizes == == Telephony == ------------------------------------ New York Telephone is reorganizing along geographical lines, it disclosed Friday. The goal is to bring services, "closer to our customers," a spokesman said, but gave no exact date for full implementation of the new organization. The reorganization creates three geographic market areas, each under a group vice president, Douglas Mello, previously president of Nynex Business Information Systems, will be responsible for midtown and southern Manhattan and for the company's special data services for its top 200 accounts. Arnold Eckelman, former assistant vice president-operations, will be responsible for norther Manhattan, the Bronx, Brooklyn, Queens and Staten Island. Particia Higgins, formerly AT&T's vice president for international sales operations, will head the company's Long Island, mid-state and upstate New York operations. The decentralization is necessary to respond to "enormous" changes in the telecommunications marketplace, including increased competition, said Richard Jalkut, president and CEO. The new organizations "will give us the flexibility we need to respond to these changes," he said. ------------------------------------ == San Bernerdino Outage == == Internal GTE/AGCS Document == ------------------------------------ On 6/19/91 at 7:34 P.M. San Bernardino, Ca. which serves 55,000 subscribers experienced a 2 hour and 9 minute outage. This outage was caused by a fault in the Space Switch Interface Controller (SIC). The SIC is the interface between the APC/TPC's and the Space Switch portion of the Base Unit Network. Without the SIC no call processing can take place since no network paths can be established. The SIC portion of the GTD-5 is a duplex device and should not cause a total outage. However, under certain double fault or backplane fault conditions a duplex device can cause system outages. San Bernardino has had a history of SIC problems, but none that had caused a problem of this magnitude. During early 1990 West Area personal worked on the SIC - and no problems were reported for 8 months. Beginning 6/21/91 (after the latest outage) I have been working with AGCS and West Area TSS personnel to resolve this problem. AGCS TAC and R&D personnel were dispatched to the site to work with local personal on Saturday and Sunday nights (6/22 and 6/23) to try and isolate the problem. While using a scope to monitor certain suspect leads, a SMA syndrome similar to the syndromes output during previous problems was output. No outage occurred. Based upon this SMA being output when the pin was touched, a decision was made to replace on of the wires that appeared to be very tight and could possibly have "worn through" insulated or could have been pulling against another pin. After replacing the wire AGCS and TSS personnel could not cause the syndrome to be generated. On 6/24/91 we held a meeting to assess the progress in resolving the problem. At that time we could not get more than a 70 percent comfort level that the fault that had caused the outage had been cleared by replacing the wire. Inspection of the wire under a microscope has not displayed any flaws. Based upon the risk that another outage could occur, TSS west and myself have recommended that the SIC backplane be replaced as soon as possible. AGCS is currently procuring the backplane. A decision has been made to use a roll around/portable frame to house a temporary SIC while the backplane is being replaced. The same concept used for the SVR 1641 16 Port BPC retrofit will be used in San Bernardino to replace the SIC backplane. This process will minimize the outage time caused by the changeout. ------------------------------------------------------------------------------- --=] National Security Anarchists [=-- If you feel that you have talent in journalism and wish to have you Name/Group appear in National Security Anarchists Newsletter, please send your submissions to The Frayed Ends of Sanity 602/861+3167.
