Hi. I'm not going to write a mad big introduction to this article, because
I dont feel their is a need for one. All I want to say here is that this
article is intended for the more "hardcore" phreak, yes, hardcore phreak, not
for lame ass calling card leeching kiddies who call themsleves phreaks. If
you are intersted in hacking telephony switches, and you have prior/prefixed
knowledge of Meridian, read on..

Through my experience, I've seen alot of meridian admins go through many
different and sometimes repetitive lengths to supposidly secure an internal
PSTN connected PABX. In this article I'm going to share my knowledge of
PBX switch hacking, and enlighten you to the intricate techneques that can
be used to "trunk hop" etc. The information provided in this article has been
obtained from my own personal accounts of hacking telephony switches, which
I'd like to state, I don't participate in anymore.

Now, for the sake of timesaving, I'll setup a possible scenario.. Consider
the following:

o You have stumbled accross a nice Meridian Mail system, which you
have already compromised by finding yourself a few boxdes in their.
You discover that the Meridian Mail system you have gained access
to belongs to a certain telco, and is used for internal
communication between emloyees high up in the hierarchial chain.

Now, any "normal" phreak would gradually take over the system by finding as
many free boxes as possible and hnading them over to friends, or would keep
the nice lil' system to themselves as a means of obtaining information about
the telco that owns the PBX, via the the means of eavesdroping on used
voicemail boxes. This is a very primitive form of remote eavesdroping, which
this file is not designed to illistrate.

Meridian PBX systems are all administered by a primary system console, which
can be remotely accessed by many different protocols. The most popular of
which is remote dialup via assigned extensions. If the companys main switch
is centrex based, it is likely that the meridian admin console is accessable
via IP on the companys intranet. If you manage to gain access to the
actual switching conponment, you are likely to have the following privalges
on the meridian based network:

o 100% control over every single inbound/outbound trunk group
o Access to every single voicemail box on the switch
o Access to trunk/group/node administration

Basically, the meridian administration module is designed to make the admin
(or whoever has access to it) GOD over the entire system, I say GOD because
you could do anything you wanted, as far as your telephony derived
imagination extends. OK, enough of this.. I'm just going to stop going on
about what if's for the time being, now I'm going to concentrate on the
factual based information, and how one would go about accessing such a
switch.

The simpilist way to find the internal dialup to a meridian switch is to
scan the internal extensions which the switch controls. It's generaly a
good idea to begin scanning network/node extensions such as 00,01,02,03[xx]
etc. What you are looking for is a modem carrier, which when you connect
should ask you for a singular password, which in most cases is bypassed
by hitting control-SD. Once you are in, you should recieve the switches
command line prompt, somthing similar to this:

>

or

SWITCH0>

OMG, I hear you think.. It looks like a DMS switch prompt.. Well, it is, in
a funny kind of way. Meridian switches are designed to emualte certain levels
of DMS-100 O/S types, so you'll find that many of the BCS leveled commands
that you know from DMS will be usefull here. The information that follows
has been obtained from public Meridian Mail Administration sources on the
net..

Basic Meridian 1 Security Audit
-------------------------------

"Users will go nuts calling a radio station to win a free toaster,
taking over all the trunks in your phone system."

An audit of the Meridian 1 telephone system will ensure that every possible
"system" precaution has been made to prevent fraud. The first step involves
querying data from the system in the form of printouts (or "capturing" the
data to a file in a PC). The next step is to analyze the data and confirm the
reason for each entry. Please be advised that this procedure is not designed
for all "networked" Meridian 1 systems, however, most of the items apply to
all systems. Use at your own risk.

PRINTOUTS REQUIRED FOR SECURITY AUDIT: It is suggested that you "capture" all
of the data from these printouts to separate files. This can be accomplished
with a PC and communications program. For the BARS LD90 NET printout, try
this file. (enclosed in faith10.zip barparse.zip)

------------------------------------------------------------------------------

GATHERING DATA FROM LD81
------------------------
List (LST) the following FEAT entries to form an information base on the
telephones.

------------------------------------------------------------------------------
NCOS 00 99 CFXA UNR TLD SRE
FRE FR1 FR2 CUN CTD
------------------------------------------------------------------------------

DATA BLOCK REVIEW ITEMS
-----------------------
From the printouts, a review of the following areas must be made. Some of the
items may or may not be appropriate depending on the applications of the
telephone system.


------------------------------------------------------------------------------
CFN - Configuration Verify that History File is in use.
------------------------------------------------------------------------------
PWD - Passwords Verify that FLTH (failed login attempt threshold) is
low enough. Verify that PWD1 and PWD2 (passwords) use
both alpha and numeric characters and are eight or
more characters long. Note any LAPW's (limited access
passwords) assigned. Enable audit trails.
------------------------------------------------------------------------------
CDB - Customer Verify that CFTA (call forward to trunk access code)
Data Block is set to NO. Verify NCOS level of console. Verify
that NIT1 through NIT4 (or other night numbers) are
pointing to valid numbers. EXTT prompt should be NO
to work in conjunction with trunk route disconnect
controls (See RDB)
------------------------------------------------------------------------------
RDB - Trunk Route Verify that every route has a TARG assigned. Confirm
Data Block that FEDC and NEDC are set correctly. ETH is typical,
however for maximum security in blocking trunk to
trunk connections, set NEDC to ORG and FEDC to JNT
Confirm that ACCD's are a minimum of four digits long
(unless for paging). If ESN signaling is active on
trunk routes, verify that it needs to be. ESN
signaling, if not required, should be avoided. NOTES
ON TGAR: For demonstration purposes, this document
suggests that sets be a "TGAR 1". The only
requirement for TGAR is that it match one of the TARG
numbers assigned in the Route Data Block
------------------------------------------------------------------------------
ACD - Automatic Verify ACD queues and associated NCFW numbers.
Call Distrobution Verify all referenced extensions.
------------------------------------------------------------------------------
DISA - Direct Remove DISA if not required. If required, verify that
Inward System security codes are in use.
Access
------------------------------------------------------------------------------
ESN - Electronic AC1 is typically "9". If there is an AC2 assigned,
Switched Network verify its use. If TOD or ETOD is used - verify what
NCOS levels are changed, when they are changed and
why they are changed. Apply FLEN to your SPNs to
insure nobody is ever allowed to be transferred to a
partially dialed number, like "Transfer me to 91800"
Study EQAR (Equal Access Restriction) to insure that
users can only follow a "Carrier Access Code" with a
zero rather than a one: (1010321-1-414-555-1212 is
blocked but 1010321-0-414-555-1212 is allowed with
EQAR)
------------------------------------------------------------------------------
NCTL - Network Use LD81 FEAT PRINT to verify all NCOS being used.
Control Does NCOS 0 = FRL 0? Does NCOS X always equal FRL X
in the NCTL? Does FRL 0 have any capabilities? - It
should not be able to dial anything.
------------------------------------------------------------------------------
FCAS - Free Call Confirm the need to use FCAS and remove it if
Screening possible. FCAS is usually a waste of system memory
and complicates the system without saving money.
------------------------------------------------------------------------------
DGT (DMI) - Digit Confirm all numbers referenced in the "insert"
Manipulation section of each DMI table.
------------------------------------------------------------------------------
RLB - BARS Route Are any RLB ENTR'S assigned FRL 0 - typically, only
List Block the RLB that handles 911 calls should have an FRL 0.
If DMI is in use, confirm all "inserted" numbers.
------------------------------------------------------------------------------
CDP - BARS Are all CDP numbers valid? Check the RLBs they point
Coordinated to and see what the DMI value is. Confirm insertions.
Dialing Plan
------------------------------------------------------------------------------
NET - ALL - BARS Add 000,001,002,003,004,005,006,007,008,009 as SPNs
Network Numbers pointing to a route list block that is set to LTER
YES. These entries block transfers to "ext. 9000" and
similar numbers. Point SPN "0" to a RLI with a high
FRL, then consider adding new SPNs of 02, 03, 04, 05,
06, 07, 08, 09 to point to a RLI with a lower FRL so
that users cannot dial "0", but can dial "0+NPA
credit card calls. Check FRL of 0, 00, 011 and
confirm that each is pointed to separate NET entry
requiring a high FRL. Remove all of shore NPAs (Like
1-809 Dominican Republic) if possible. Regulations
are almost non-existent in some of those areas and
they are hot fraud targets. Verify blocking 900 and
976 access. Also consider blocking the NXX of your
local radio station contest lines. Users will go nuts
calling a radio station to win a free toaster, taking
over all the trunks in your phone system. Restrict
the main numbers and DID range within the BARS
system. There is no need to call from an outgoing to
an incoming line at the same location.
------------------------------------------------------------------------------
TRUNKS Confirm that all trunks have TGAR assigned. Confirm
that all incoming and TIE trunks have class of
service SRE assigned. (caution on networked systems)
Confirm that all trunks have an NCOS of zero.
NOTES ON TGAR: For demonstration purposes, this
document suggests that sets be a "TGAR 1". The only
requirement for TGAR is that it match one of the TARG
numbers assigned in the Route Data Block
------------------------------------------------------------------------------
SETS-PHONES Does every phone have a TGAR of 1 assigned? (This
must be checked set by set, TN by TN). Can you change
every phone that is UNR to CTD? Review LD81 FEAT
PRINT to find out the UNR sets. CTD class of service
is explained below. Confirm that all sets are
assigned CLS CFXD? Confirm that the NCOS is
appropriate on each set. In Release 20 or above,
removing transfer feature may be appropriate. Confirm
that all sets CFW digit length is set to the system
DN length. NOTES ON TGAR: For demonstration purposes,
this document suggests that sets be a "TGAR 1". The
only requirement for TGAR is that it match one of the
TARG numbers assigned in the Route Data Block Apply
Flexible Trunk to Trunk Connections on the set, and
FTOP in the CDB if deemed appropriate. These
restrictions are done on a set by set basis and allow
or deny the ability to transfer incoming calls out of
the facility.
------------------------------------------------------------------------------
VOICE MAIL PORTS Each port should be CLS of SRE Each port should be
NCOS 0 - NCOS 0 must be known to be too low to pass
any call Each port should be TGAR 1 (all trunk routes
must be TARG 1 also) NOTES ON TGAR: For demonstration
purposes, this document suggests that sets be a
"TGAR 1". The only requirement for TGAR is that it
match one of the TARG numbers assigned in the Route
Data Block NOTE: If you are used to your Mail system
doing outcalling, you can forget about that working
after applying these restrictions.
------------------------------------------------------------------------------

CLASS OF SERVICE AND TRUNK GROUP ACCESS RESTRICTIONS:
-----------------------------------------------------
EXPLANATION OF CLASS OF SERVICE SRE:
------------------------------------
NTP DEFINITION: Allowed to receive calls from the exchange network.
Restricted from all dial access to the exchange network. Allowed to access
the exchange network through an attendant or an unrestricted telephone only.
Essentially, an SRE set can do nothing on it's own except dial internal and
TIE line extensions. If a trunk is SRE - it will work normally and allow
conference calls and transfers.

EXAMPLES OF 'SRE' IN USE:
-------------------------
Voice Mail cannot connect to an outgoing line, but can receive incoming
calls. Callers on the far end of a TIE line cannot call out through your end
(for their sake, both ends should be SRE).

EXPLANATION OF CLASS OF SERVICE CTD:
------------------------------------
If a route access code is accessed (if there was no match between the TGAR
and TARG), the caller cannot dial 1 or 0 as the leading digits. If the caller
makes a "dial 9" BARS call, the NCOS will control the call.

EXPLANATION OF TGAR AND TARG:
-----------------------------
The best restriction is to have all trunk routes TARG'd to 1 and all TNs
(including actual trunk TNs) TGAR'd to 1. This will block all access to
direct trunk route selection.

BENEFITS OF IMPLEMENTING THESE SECURITY RESTRICTIONS
----------------------------------------------------
No incoming caller will have access to an outside line unless physically
transferred or conferenced by an internal party. If voice mail ports are SRE
and NCOS 0 and have a TGAR matching the TARG - they will not be able to
transfer a call out of the system, regardless of the voice mail system's
resident restrictions assigned. No phone will be able to dial a trunk route
access code. Consider allowing telecom staff this ability for testing.

Layered security:
-----------------
If in phone programming, TGAR was overlooked on a phone, the CTD class of
service would block the user from dialing a 0 or 1 if they stumble upon a
route access code. If in programming, the CTD class of service was
overlooked, both TGAR and NCOS would maintain the restrictions. If in
programming, the NCOS is overlooked, it will defaults to zero, which is
totally restricted if NCTL and RLBs are set up correctly.


Quick Tour of a Simple Meridian 1 BARS Call
-------------------------------------------
Basic Automatic Route Selection. If you dial "9", you are accessing BARS.
"9" is the "BARS Access Code"

1. A telephone dials "9" - BARS activates.
2. The telephone calls a number - Example: 1-312-XXX-XXXX
3. The PBX hold the digits while it looks up "1-312" to figure out what
Route List to use for processing the call.
4. The Route List determines the possible trunk routes that can be used.
5. The Route List checks the facility restriction level of the telephone
and compares it to its own required facility restriction level.
6. The Route List checks to see if any special digit manipulation should
be performed.

LD90 NET
--------
The LD90 Network overlay is where area codes and exchanges are defined. If a
prefix is not entered into LD90, it cannot be dialed through BARS. Each area
code or exchange refers to a "Route List" or RLI which contains the
instructions for routing the call.

LD86 RLB (or RLI)
-----------------
The RLB is a "list" of possible trunk routes that an area code or exchange
can be dialed over. Each "ENTR" or list entry contains a trunk route. Each
entry also has a "minimum Facility Restriction Level" or "FRL" that must be
met before a phone can access that entry. In the following example, the first
entry can be accessed by phones whose NCOS equals an FRL of 3 or above. The
second entry can only be accessed by phones whose NCOS equals an FRL of 6 or
above. Along with the trunk route and the FRL, you can apply specific "digit
manipulation" with the DMI entry. The DMI entries are explained here.

LD87 NCTL
---------
The FRL to NCOS "relationship" is built in the NCTL data block. The FRL and
the NCOS do not necessarily have the equal one another, however they usually
do. A higher FRL/NCOS has more capability than a lower FRL/NCOS. For an NCOS
number to have any capability, it must first be defined in the NCTL data
block.

Very rarely, I can not dial up the host MCA card. It simply won't answer, so
the following usually clears it up:

ITEM
ITEM OPE YES
DCD ON
PRM OFF

If that doesn't work, since 020 0 04 31 is "digital", it could be disabled.

LD 32 and ENLU it.

You could very easily modify this script to say, change an ASCII list of TNs
/TYPEs to TGAR 1, and have it executed at 2:00 a.m. The s0 and s1 variables
would change from DN & NAME, to TN & TYPE, and add Waituntil "2:00:00" "7/16
/99" to kick it off at 2:00 a.m.

Little Known Meridian 1 Features And Programming Tricks
=======================================================
HELP and Error Lookup

HELP - Type " ? " at many prompts
LOOKUP - At " > " sign, type
ERR AUD028 to find out what AUD028 indicates.
At any other prompt, type " ! ", then you will receive " > "
symbol for getting ERR lookup.

Find Sets with a Certain Feature
================================
LD81
REQ LST
FEAT CFXA
FEAT UNR

Lists all sets that have the "Call Forward External Allow"
feature, then lists all UNR sets.

Inventory and Identification Commands
=====================================
LD32
IDU l s c u (or) IDC l s c
LD22
CINV (and) ISSP
LD30
UNTT l s c u

Speed Call Stuff
================
Create many Speed Call lists at once. LD18 REQ: NEW 100 - Creates 100 lists.
When memory is plentiful, make Speed Call list number the same as the persons
DN. Need to increase MSCL in LD17 Find a "Controller" in LD81 by: REQ:LST,
FEAT:SCC, then the Speed List Number

Allow Restricted Sets to Dial Certain Long Distance Numbers.
============================================================
Add the numbers to a System Speed Call List. Assign an NCOS to the "List"
that replaces the users NCOS during the call. Alternate: Add the suffix of
the telephone number to an ARRN list in the prefixes RLI. This will point
only that number to a new RLI with a lower (or higher if you choose) FRL.
Look up ARRN in LD86

PBX Clock Fast or Slow?
=======================
LD2
SDTA X Y -- x y
X = 0 for "subtract time each day" -or- 1 for "add time each day"
Y = 0-60 seconds to be added or subtracted each day.
Daylight Savings Question?
TDST Look this one up in LD2 before changing

Phantom DNs, TNs, and "MARP to Voice Mail" TNs
==============================================
Phantom TN with FTR DCFW ACD Queues with NCFW but no Agents 2616 Sets with
AOMs (AOMs can be in "software", but do not need to be "installed" on the
set). This is an excellent "MARP TN" for DNs that need to HUNT/FDN to Voice
Mail

Digit Display on Trunk Routes and ACD Queues
============================================
Find Trunk Route Access Codes - name in LD95 like any other DN ACD Numbers -
name in LD95 like any other DN IDC Numbers - name in LD95 at DCNO prompt.

Limited Access Passwords
========================
Print PWD in LD22 before starting
LD17
LAPW 01
PW01 12345
OVLA 10 11 20

Identify Trunks, Routes and TTY Ports with "DES" Entry
======================================================
LD17 ADAN
DES can be 1-16 characters
LD16 RDB
DES can be 1-16 characters
LD14 TRK
DES can be 1-16 characters
TKID - enter telephone number

Free Up or Block DN Range
=========================
Change your SPRE Code to 4 digits LD15 - SPRE XXXX Assign all current feature
codes as Flexible Feature Codes To hide DNs from appearing in LUDN printouts,
enter DN prefix ranges as an FFC for "Ring Again Activate"

Save "Call Forward" Status upon Reload/Sysload
==============================================
LD17
CFWS YES

Call Waiting "Buzz" on Digital Sets is Not Long Enough
======================================================
Turn on Flexible Incoming Tones Allowed
LD15
OPT SBA DBA
LD 11
CLS FITA

"DSP" Display Key Applications
==============================
Youre on the phone, another call comes in...Press DSP, then ringing line to
see whos calling. Press DSP, then Speed Call, then entry number to view
entries. Rls23 Update - automatic Display CLS TDD

NHC - No Hold Conference
========================
With NHC, other party is not placed on hold while adding conferees. You can
also disconnect conferee called with NHC
LD11
KEY X NHC
Rls23 Update - Conf. Display/Disconnect
LD11
CLS CDCA

Call Forward Indication on 2500 Sets
====================================
Add Call Forward Reminder Tone. Special dial tone is heard only when call
forwarded.
LD15
OPT CFRA

Override Call Forwarded Phone
=============================
Add Flexible Feature Code for "CFHO". Dial CFHO code, then dial extension.
LD57
CODE CFHO
On sets needing ability to perform override
CLS CFHA

Call Forward ONLY Internal Calls - Let Externals Ring
=====================================================
Great when you need to prioritize external callers.
LD11
KEY X ICF 4 ZZZZ

"Delayed" Ring on Multiple Appearance DNs
=========================================
Non-ringing (SCN) keys will ring after a certain duration. Great for areas
where many of the same DNs appear.
LD11
DNDR X
(X = 0-120 seconds of delay before SCN keys will start to ring)

Audible Reminder of Held Calls
==============================
Receive "buzz tone" every X seconds to remind user that call is on hold. Also
reminds user that Conference/Transfer was mishandled - call was never
transferred
LD15
DBRC X (X = 2-120 seconds between reminders)
LD11, CLS ARHA

Which Call "On Hold" is Mine
============================
Exclusive Hold sets held calls to "wink" at holding set, but stay "steady" at
other sets.
LD10/11
CLS XHA

Change Ring Cadence/Tone
========================
There are 4 ring styles, adjusted in the CLS of the digital set.
LD11
CLS: DRG1 -or- DGR2 -or- DRG3 -or- DRG4
Set pesky customer phones to DRG4 !

BFS - Nightmare in Shining Armor ?
==================================
BFS Keys allow the user to monitor the Call Forward and busy status of a set,
activate and deactivate Call Forward, and can be used as an Autodial key.
NOTE: Cannot perform MOV command with BFS. User can also forward sets by
accident.
LD11
Key XX BFS l s c u (target sets TN)

More Than 4 DNs Answered by One Mailbox?
========================================
Add up to 3 DNs to DN list in mailbox programming. Add 4th and all additional
DNs in "Voice Service DN" (VSID) Table and set to "EM" to the mailbox.

1 Single LineTelephone, 3 DNs, 3 Users, 3 Mailboxes? How?
=========================================================
Create one 2500 set with one of the three DNs. Create 2 Phantom TNs, each one
with a new DN and DCFW each of them to the 2500 sets DN (from above) Add the
three mailboxes…now any of the three numbers will ring the one set, but
messages will be separated!

Change An NCOS After Hours
==========================
Here's an excerpt from the LD86 ESN data block that has NCOS 3 & 4 change to
NCOS 2 after 4:30PM and all day on weekends

<snip>

AC1 9
AC2
DLTN YES
ERWT YES
ERDT 0
TODS 0 06 00 16 29
7 00 00 05 59
7 16 30 23 59
RTCL YES
NCOS 0 - 0
NCOS 1 - 1
NCOS 2 - 2
NCOS 3 - 2
NCOS 4 - 2
NCOS 5 - 5

<snip>

Oops..the Console Went Into NITE...During the DAY!
==================================================
Use NITE entries that are based on "Time of Day". See Night Service in
Features Book If the console goes into NITE during the day, send them to
either a set of DNs next to the console, or a voice menu/thru-dialer
explaining that there are "technical difficulties". After hours, NITE calls
goes to where they should.

Just Two Security Tricks
========================
Create SPNs in BARS of: 000 thru 009 and create a Route List Block for them
with LTER=YES Now when Phreakers ask for extn 9000, they get nobody. Use the
FLEN entry on SPNs 0, 00, 011 so that nobody can transfer a caller to 9011,
90, etc.

Break Into Meridian Mailbox?
============================
Simply make the mailbox "Auto-logon". For remote access, add their DN to your
set. Convenient if you need to access an employees mailbox without changing
their password. Useful for modifying greetings of an absent employees or
allowing a temporary employee access to a mailbox without divulging the
regular employees password.

Tracing Phone Calls
===================
TRAC 0 XXXX (X=extension)
TRAC l s c u
TRAC l s c u DEV (Adds BARS info)
TRAT 0 X (X=Console number)
TRAD (see book, traces T1 channels)
ENTC (see book, traces TN continuously - up to 3 TNs at a time ! )

Forgot your M3000 Directory Password?
=====================================
LD32
CPWD l s c u

Another Idea
============
Use a PC to log into your PBX, then activate the "capture file". Now run a
TNB and keep it as a file rather than on paper. If your TNB file is large,
try a high power text editor, which can open even 20meg files in seconds.
Search the Internet "Text Editor" Keep copies so you can go back and see how
a set was programmed when you out it by mistake.

*/

Using the above information you could sucessfully do the following:

a) Setup your own trunk configurations that allow outgoing calls.
b) Reset lines and trunks, reconfugure lines and trunks.
c) Set an internal extension(s) to share the same multiplexed trunk as you
so you can effectivly listen in on any incomming/outgoing phone call
made on that extension.
d) Set up calls that don't exist with no trunk assignment.
e) Set any users voicemail box with auto-logon paremters temporarily.
f) Close down the entire network
g) Set every phone in the company to ring forever...
h) Re-route incomming/outgoing trunk calls to any destination.
i) Park your own incomming line as "on console" so you can answer calls made
to a pre-set extension.
j) Make yourself the company oprtator.
k) Trace phonecalls, audit logs etc.
l) Set all trunks to loopback on one another.
m) Anything you want?

Thats just a few ideas. But before you do ANYTHING, you should be aware that
anything you do could have devestating impact on the companys phone switch.
For example, say you accidently commanded the system to shut down.. You would
effectivly be killing 6000+ peoples phone lines, which would yield colosal
financial burden/loss onto the company. Generaly I'm just saying, be nice..
Just because you have the power to do such things, it doesnt mean you have to
do it. :)

A final note: In the aftermath of obtaining access to a merdian switch, it is
generaly advisable to erase all trace of you ever being on there. This can
be achived by reseting trunk audit logs, and erasing any log of your incoming
trunk setups. Therefore, if the real admin decided to track what was going on
he/she would get nowhere because the lines you used to initially call into
the system DO NOT EXIST. Its just a case of using your imagination. Don't be
destructive, Don't alter anything that would be noticed, Generally don't be
a f00l.. Thats the end of this file, I hope you enjoed it. Take it easy.
