With the FBI watching us all the time, you can never be sure if its safe to say something. Even if your not into good stuff, its still nice to know that your the only one on the phone. You don't want your sister listening in on you. It is also well known that alot of the major BBS's are being monitored by the feds. Well, we hope that the information presented here will allow you to feel safer on your telephone. Most telephone surveillance devices used on hackers numbers are very simple. They usually save the good stuff for spys and people like that. It is impossible to tell if the good stuff is on, but we have listed ways to detect some of the cheaper machines, and in some cases how to shut them off or screw them up. The MLT-2. This device is one of the mainstays of BS (BELL security). Its main weakness is in that give tones to do its operation. A friend of MAD!'s is currently working on a device he plans to call a purple box that will detect these tones. You will just be able to keep it on, and it will report on any such tones. We will keep you updated in future files. Ok, if the MLT-2 is in MON (monitor) mode, you can do the following: A good old loud 2600hz will usually switch it to LOOP mode. Some times a 7200 will execute a TT (dial mode). These will get them off your back for a while. If you own a MLT-2 also, you can damage the other MLT-2. First get the other MLT-2 into loop mode. Now wait till it gets to LIN (test the inside part of the loop). Now do a K2. This will put the MLT-2 into a state of limbo. Now to finish up, do a MLT SOAK test. This will put the offending machine out of commission for a little while. If you have an OMEGA BOX (nice little things), a flat tone will put the MLT-2 into a LRM (fast loop measurement), thus getting it off your line). CONDUCTER TAGGER and ANALYZER test. This will show you approxamatly how many people are on a line. First you need to hook a volt/ohms meter up to the phone box in your wall. Hook the line and the ground up to the red and green wires. You can use one made for it, or you can modity the kind you use to check batterys by putting aligator clips on it. Now the volt meter will rise an fall depending on how many people pick up the phone, and how good the connection is. If your sister picks up the phone, it will fall. It picks up operators, and whatever. Most of the cheaper tapping machines will be detectable. Tape recorders can also be detected. Even a person on a test phone will show up. Its a great tool. Try using it on conferences some time. If you have friends (or enemys) that like to listen to their phone conversation out a phone boxes with test phone theres something you can do about it. The following information comes from Abbie Hoffman and George Hayduke in the classic book 'Getting Even' the complete book of dirty tricks. Cut the female end off an ordinary extension cord. Unscrew the mouthpiece on the telephone. You will see a terminal for a red wire and one for a black. Attach one of the wires from the extension cord to the red, and one to the black. Now plug the extension cord into a power socket. According to Hoffman you are sending 20 volts of electricity back through equipment made for 6 volts. Fizz. Any infomation that is passed over phone line can be intercepted by the phone company. Thanks to MR. X of a bell company we have learned how to defeat most surveillance devices using Blue/Omega boxes. The blues range is very limited, but the omega boxes covers most of them.

ADS monitoring test. ADS is the new trace/monitoring test being used by AT&T, MCI, soon SPRINT, and more. It is very fast and accurate, but it has many many faults. After much testing we found that if you do a 7200 and ADS is on the line, a volt meter will go go crazy. A simple gold will make a pop if ADS is on the line. For a lot more on ADS see MAD!'s upcoming DETECTING LINE TRACES. TAP TEST NUMBERS Lately MAD! has as been seeing alot of those tap test #'s. Our friends at the phone company said there are such #'s, but they will only detect certain things. Here is a small list. We are not sure if they work, and didn't have time to test them. We will print the results in an upcoming file. If they do, we will print about 25 of them. This came from someone named JOHN DOE but were not sure what system. Here it is... I GOT A # TO SEE IF YOUR BEING TRACED. WHEN YOU CALL IT USING YOUR PHREAKING SERVICE,YOU SHOULD HEAR A TONE THAT GOES UP IN FREQUENCY,THAT MEANS YOUR NOT BEING TRACED. IF YOU HEAR A STEADY TONE, THEN YOUR BEING TRACED AN YOU'D BETTER HANG UP IN LESS THAN 30 SECONDS OR YOU RUN THE RISK OF BEING TRACED...THE # IS 617-890-9900. ENJOY, HACKER SMITH Also you see the number posted around 200-xxx-xxxx. This is a ADS system used by bell linemen from phone boxes (see the MAD! file on TEST PHONES for info on phone boxing.). It is not a trace test at all.
