Almost certainly a shortened version of "WarGames
dialer", from the film WarGames.
1. carrier scanner
2. A program which attempts to break a password of known
length by iterating thru all possible combinations of
characters that could make up that password.
This approach is not feasable for cracking most passwords
these days. However, as late as the mid-1980s, some
long-distance companies required only very short numeric
access codes (e.g. five digits) to verify the identity of
their customers. Wardialers were created which would, running
unattended, call up long-distance providers' local connect
numbers and iteratively try possible access codes. Codes
which worked were logged for later illicit use.
These wardialers had a high success rate because of the small
range of possibilities to iterate through, e.g. 10000 for a
five digit access code, compared to hundreds of trillions of
combinations for an eight-character alphanumeric code.
Long-distance providers soon required longer passwords and
took advantage of technology for rapidly tracing the phone
numbers that wardialers were being run from, such that running
wardialers became pointless and dangerous.

(jargon) | demon dialer
n.
A program which repeatedly calls the same telephone number. Demon dialing
may be benign (as when a number of communications programs contend for
legitimate access to a BBS line) or malign (that is, used as a prank or
denial-of-service attack). This term dates from the blue box days of the
1970s and early 1980s and is now semi-obsolescent among phreakers; see {
war dialer} for its contemporary progeny.

war dialer
(jargon) | war dialer
n.
[originally from ‘wargames dialer’, a reference to the movie War Games] 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). Some of these programs
have become quite sophisticated, and can now detect modem, fax, or PBX
tones and log each one separately. The war dialer is one of the most
important tools in the phreaker's kit. These programs evolved from early
demon dialers.
