FoIP, short for
Fraud over Internet Protocol, is the act of taking
advantage of
VoIP security vulnerabilities to steal
network capacity. The term was used after a
well-known criminal case where two men tapped into corporate and
service provider networks and routed millions of minutes
in calls illegally. One of the first uses of the term FoIP as an acronym for
Fraud over Internet Protocol
appeared in an article on
Datamation. (Datamation is owned by the same parent company as Webopedia.)
