-
- NOTE1: In case you didn't know VMB stands for Voice Mail Box
-
- NOTE2: This is the information that I have gathered from hacking
- Meridians, and is not guaranteed to be 100% accurate
-
- NOTE3: Disclaimer : There is none, I did this article to encourage people to
- go and fuck around with Meridians, so sue me.
-
- ------------
- Introduction
- ------------
-
- Before we begin, Let's shed a little light on the subject of Meridian. This
- is one of my favorite VMB systems to hack, because:
-
- Number 1 : There are many Meridian VMB Systems throughout the country, in
- -------- 800 exchanges and numbers local to you. You can bet that there
- are at least 10 - 15 different corporations using Meridian
- throughout your area code
-
- Number 2 : (The Most Important by far.) Almost ALL Meridian mails
- -------- use the Mail Box number as the default password. (Unless changed
- manually)
-
- Number 3 : About 95 percent have outdialing features. Most don't have long
- -------- distance access, but this can still be very useful for diverting
- calls, and getting free calls in that area code.
-
-
- Ok, enough light shed on the matter. Let's get to identifying and hacking
- those fuckers!
-
- --------------------------
- Identifying Meridian VMB's
- --------------------------
-
- Most Meridian VMBs just come right out and say exactly what they are. I'd
- say about 8 out of 10 will just come out, right after it answers and say:
-
- "MERIDIAN MAIL"
- <wait 1 second>
- "MAILBOX?"
-
- or just
-
- "MAILBOX?" (it is ALWAYS a female computer [digitized] voice)
-
- Half the time you will only hear "RIDIAN MAIL". (This must be caused by
- a timing bug in Meridian.) Once you hear that, write the # down, since
- it may be useful in the future for such things as 3rd party billing
- (more on that later), as a code line or just as a personal VMB. If you know
- for a fact (or a guess in that matter) that this is a Meridian mailbox but
- when you call it, it just says 'Leave a message' or has someone actually
- talking instructing you to leave a message, then you have reached what might
- be a direct VMB line. These are usually numbers people pay more money for, that
- will give them a direct 800 number instead of going through the "mailbox #"
- part.
-
- These are the best, but probably the hardest to hack, because even though
- (according to a recent poll) about 70% of people are stupid enough to leave
- their mailbox number as their password, if you are serious and want to
- pay that much for a direct line, you are probably going to change the
- password. Even though I have seen many that do have the default, the
- odds are against it.
-
- Ok back to the point. If you find a direct VMB, call all the numbers around
- it, because chances good are that you will find the system that just asks
- for a box number, very close. I would recommend about +50 numbers and -50
- numbers and you'll find the root system. You will also find many other
- direct boxes in your quest.
-
- NOTE: The ROOT SYSTEM is the number you call and simply hear 'MAILBOX' or
- 'MERiDiAN MAiL'
-
- Another thing to remember is that you have to find out how many digits your
- mailbox #'s are going to be. The number of digits I've seen in my career
- differs from about 2 digits (rare) to 6 (also fairly rare). The most likely
- # of digits it will probably have is 4, or 5... Call your VMB and when it asks
- for mailbox #, hit '111#' (Note: You ALWAYS have to end a command on a Meridian
- mail system with an '#') if it says (with a quick response) 'INVALID box #'
- then try a 4 digit code. Sometimes (yeah, I know it sucks) you will
- have to fuck around for a while before you can tell how many digits, or even
- worse you may never know, and have to keep alternating #'s of digits, until
- you hit a valid box.
-
- Hacking The Fuckers:
-
- First off, think of what you are going to record as an outgoing message before
- you go and hack it. Decide if this should be a code line, or a personal VMB,
- or... Both? Here are the first default boxes you should try before dialing
- random ones:
-
- 111 222 333 444 555 666 777 888 999 000 100 200 300 400 500
- 600 700 800 900 123 234 345 456 567 678 789 890 901 121 212
- etc. etc. etc.
-
- If boxes are 4 digits, add a trailing number. If you don't know the length,
- mess around a while, you'll get one.
-
- If you call someone's direct VMB and you hear a message like "You have
- reached So&So's VMB please leave a message, and I will return your call as
- soon as possible" there are a few ways to transfer to a different mailbox.
- Try simply hitting #, that might just hang up on you, unfortunately.
- Call back try hitting *. When you hear 'MAiLBOX' you just struck home.
- Try entering 123#.
-
- Now, a few things can happen. Either:
-
- 1 It will transfer you to 123's mailbox
- 2 It will say invalid mailbox, or simply 'MAILBOX' again
- 3 It will say Password
-
- When you hear 123's mailbox you can try and hack it by hitting *, and hope
- it will ask 'PASSWORD?' If it doesn't then you can't do much with this
- system except leave messages for that person (What Fun). If it does ask
- "PASSWORD?" then try the box # as the default password. (On your quest for a
- valid VMB you will find that MANY MANY people are total fucking morons
- and keep their password at the default) others will make it something easy to
- remember like 123# or 111# etc. etc. etc. If the password is not the Default
- then just write this number down in a notebook and move on.
-
- If all else fails and you can't figure out how to get to the MAILBOX prompt you
- should call all the #s around the one you found to try and find the root
- system.
-
-
- If you get in, (with the default or otherwise) it will probably say:
-
- 'MAILBOX EMPTY' or 'YOU HAVE n MESSAGES'
-
- If you press 7* it will reply with:
-
- Message option 0 (unknown at this time)
- Reply 1 (used to reply to a previous message)
- Play envelope 2 (unknown at this time)
- Forward 3 (Forward your mail to another box)
- Reply all 4 (Reply with a multi-mail)
- compose 5 (send multi-mail)
- delete 6 (used to delete mail [duh])
- send 9 (sends single mail [must have mailbox number ready)
-
-
- if you press 8* it will reply with:
-
- Mailbox options 0 (Changes operator code (not useful)
- login 1 (Gives you the option to transfer mailbox's)
- greeting 2 (Can change greeting (internal & external)
- logoff 3 (Kicks you off the system)
- password change 4 (Changes VMB password [verifies 2x]
- distribution list 5 (Not useful)
- goto 6 (Takes you back to 'MAILBOX EMPTY'
- Personal verification 9 (Lets you record a name for personal verify)
- to exit press # (logoff)
-
- This is not all very useful, the most you can do with these commands is listen
- to people's mail (which can be fun), and/or take it over for your own code line
- or personal VMB. The whole point of hacking Meridians is the outdial function.
- Once you have successfully gotten into the VMB dial '0*' (Zero-Star).
- It should say:
-
- 'YOU HAVE REACHED A SYSTEM THAT WILL CONNECT YOU TO THE NUMBER THAT YOU ENTER.
- PLEASE ENTER THE NUMBER OR THE NUMBER OR THE NAME OF THE PERSON YOU WISH TO
- REACH. PRESS 11 FOR A NAME, SPELL THE LAST NAME THEN THE FIRST NAME blah,
- blah, blah.'
-
- This is the jackpot. With this you can call ANYWHERE (hopefully) for free, any
- time (unless the VMB has hours [...some do...]) To dial out, try this first:
-
- just dial a local number (ex 432-1342#)
-
- >From there it may beep and say 'THAT # CANNOT BE REACHED' or it may connect
- you. If it connects you, great! You just found an untraceable way of hacking!
- Call back and try 1-npa/xxx-yyyy (if that works, then abuse the hell out of it
- as soon as possible, because it wont last for long :) ) If those two methods
- don't work try these.
-
- 9+1+npa/xxx-yyyy (works most of the time)
- 8+1+npa/xxx-yyyy (not probable)
- 0+1+npa/xxx-yyyy (Possible)
- 9+xxx-yyyy
- 8+xxx-yyyy
- 0+xxx-yyyy
-
- If none of those work, then you're shit out of luck. Use it for a code line.
- If it did work, think of the possibilities, 900 numbers (for gaining access
- to boards), Tons of free LD, untraceable calls............
-
- On to the last subject of part 1.
-
- ------------------------------
- Another Way To Make Free Calls
- ------------------------------
-
- Sorry, this only works on Direct VMB's, sometimes only the ones in your local
- exchange, its a long shot, but hell, its free. (But don't do this from your
- home phone, stupid.)
-
- Change the outgoing message on the direct VMB to 'Operator, this number accepts
- all collect and 3rd party billings' Call up the operator and ask for AT&T,
- once they come on tell her you would like to make a 3rd party billing. Tell
- her the number you're billing to is the VMB #, then tell her the number you
- wish to call. She'll say, "wait," AND a few moments later she'll come back
- and say they accepted. Presto! You're in!
-
- If you get busted, say you read a text file on how to do it, you didn't think
- it would work... (act innocent, alwayz worked for me :)
-
-
- You can leave me comments, suggestions or threats at my VMB
- (not a Meridian currently) *(800)775-0728* (direct)...
