Fake HP Printer That's Actually a Cellular Eavesdropping Device

Julian Oliver has designed and built a cellular eavesdropping device that's disguised as an old HP printer.

Masquerading as a regular cellular service provider, Stealth Cell Tower surreptitiously catches phones and sends them SMSs written to appear they are from someone that knows the recipient. It does this without needing to know any phone numbers.

With each response to these messages, a transcript is printed revealing the captured message sent, alongside the victim's unique IMSI number and other identifying information. Every now and again the printer also randomly calls phones in the environment and on answering, Stevie Wonder's 1984 classic hit I Just Called To Say I Love You is heard.

Okay, so it's more of a conceptual art piece than an actual piece of eavesdropping equipment, but it still makes the point.
