carrier scanner
<security> (Or "wardialer") A program which uses a modem to dial a series
of phone numbers (say, from 770-0000 to 770-9999), and keeps a log of what phone
numbers answer with a modem carrier. The results of such a search were generally
used by people looking to engage in random mischief in random machines.
Since the 1980s, wardialers have generally fallen into disuse, partly because of
easily available "caller ID" technology, partly because fax machines are now in
wide use and would often be logged as a carrier by a wardialer, and partly
because there are so many new and more interesting venues for computerised
mischief these days.
