ModemScan is a Microsoft
Windows software program which facilitates the auditing and discovery of
modems and FAX machines. This type of software is commonly referred to as a
wardialer or war dialer. Wardialing (also known as telephone scanning or
war dialing) is the practice of dialing all the phone numbers in a range in
order to find those that will answer with modem or FAX tones.
Definition:
war dial or wardial
(noun)
To use a cracking tool, a program that calls a given list
or range of phone numbers and records those which answer with handshake tones
(and so might be entry points to computer or telecommunications systems). The
war dialer is one of the most important tools in the phreaker's kit. These
programs evolved from early demon dialers.
Why does your
organization
need the ModemScan™ wardialer?
Remote access into many
organizations' information systems is sometimes available through ordinary
analog phone lines, also known as POTS (Plain Old Telephone Service) lines.
Hackers use software tools war dial these phone lines. They usually target all
the phone numbers owned by a local company or organization. After
systematically dialing all or some phone numbers, also known as wardialing,
war dialing or telephone scanning, they extract numbers which returned
information about the remote systems in the targeted organization. This first
line of information, known as the "banner", is then used to try default or
weak passwords for that specific system. Following this simple process
repeatedly, usually allows unauthorized access into the target's IT systems.
Why not wardial with
other freely available wardialers?
Other
wardialers (war dialers) are difficult to configure, hard to schedule over
multiple days, and usually leave you sifting through hundreds, if not
thousands, of pages of irrelevant data in a plain text file. For past users of
ToneLoc, ModemScan, will save hours of time just in configuration, let alone
reporting.
What can a company do to
protect its Information System resources against unauthorized wardialing?
Periodic and systematic
auditing of all owned phone lines by wardialing (war dialing) is the current
methodology used by most security departments and external auditors for modem
detection. ModemScan can facilitate this process and provide reports of all
modems which responded and the type of response discovered during the war dial
process.
