Re: [PEN-TEST] War Dialling

I would warn you that the PBX list is not the real list you want.  All companies have non PBX or DID lines - straight 
analog lines...  All companies using a PBX have locations with needs for a non dial 9, prefix numbers so these are the 
ones you should concentrate on getting.  Get the actual phone bills so you can validate the "actual" listing of numbers 
you really own.  On our side I found twice as many modems on the analog lines as I found on the PBX lines.  Also most 
PBX systems allow you to print the settings so you could just turn the ports off and see who complains and replace or 
secure the system that was connected to the port and update the PBX entries and your lists.  Also make it a policy that 
all analog lines MUST go through the modem pool (if you have one) and the PBX 2nd choice and prohibit non-controlled 
analog lines.

I've found that it is always best to go directly to the PBX switch
administrators to get the range of numbers that are valid.  You can then use
ranges of a data file of valid numbers in tools like ToneLoc or THCscan.

Subject: [PEN-TEST] War Dialling


Being a new member to this list I am not sure how much this topic has been
aired.  How ever I wonder if anyone has any ideas, or pointers on how they
would eliminate irrelevant numbers on a war dialling exercise.

If acme.com, a global company, has a very wide range of numbers how is it
best to seek out the numbers that are relevant to the IT departments.
Obviously there is the social engineering approach, however I am interested
in any other ideas.

Apologies if this has been discussed B4
