A fake HP printer that's actual an office-camouflaged cellular eavesdropping device
Scary. "Oliver’s creation isn’t intended merely to stage an elaborate office prank. He wants to demonstrate the inherent privacy flaws of the cellular connections our phones depend on. His Stealth Cell Tower, after all, is no different from the devices known as IMSI catchers, or “stingrays,” that police use to hijack cellphone connections and spy on and track criminal suspects. “GSM is so broken and phones are so desperate to get hooked up that they’ll just hop onto anything that looks like a cell tower,” Oliver says. “IMSI catchers are most commonly deployed at protests. It’s worrying, when you’re looking at activist movements organizing themselves over SMS and calls.” Instead, he says, his mischievous printer should serve as a reminder to the paranoid to end-to-end encrypt their communications. He recommends the free encryption app Signal. “My project is intentionally built to humiliate GSM in a sense,” says Oliver. “It’s broken, and we need to encrypt our stuff end-to-end.”"
