blue box
Where recyclables go
A blue box is a device that generates tones to manipulate telephone switching systems, historically used to make free long-distance calls by bypassing billing.
The term gained notoriety in the 1970s when phone phreakers, including early tech pioneers, exploited AT&T's signaling vulnerabilities.
Blue boxes became obsolete as telephone networks moved to digital switching.
The term now sometimes refers to any unauthorized hacking device.
