Cell-site simulators (CSS, also known as Stingrays or IMSI catchers) are devices that masquerade as legitimate cell-phone towers, tricking phones within a certain radius into connecting to the device rather than a tower. Our new tool, Rayhunter, can help you find them. https://www.eff.org/deeplinks/2025/03/meet-rayhunter-new-open-source-tool-eff-detect-cellular-spying
Meet Rayhunter: A New Open Source Tool from EFF to Detect Cellular Spying

Rayhunter is a new open source tool weโ€™ve created that runs off an affordable mobile hotspot that we hope empowers everyone, regardless of technical skill, to help search out cell-site simulators (CSS) around the world.

@esoteric_programmer @eff @pluralistic Much of @pluralistic 's most dystopian shit is 100% real. The rest is technically feasible.

@Plumbert @eff @pluralistic so, the 3d printed federated disney ride from makers can also be real? if those things presented in there could exist, then we could do so much, especially if we could, somehow, 3d print circuitry, we could 3d print computers even, or other 3d printers, the possibilities are endless. Imagine if even half the tech from walkaway could exist, obviously excluding the whole people's brains being transfered to computers part, we would have much more of a chance to make a better world

A funny story about this (or somthing similar), in Oslo a few years back someone used similar tech to try to swindle people on the street. So they picked the most populated street in the countrey, karl johans street. The thing is that it was near parlament, stortinget. So when they were trying to scam people, they suddenly got arrested for spying on parlament. (The charges was later changed to trying to scam people.)

these things are useually ilegal because you need a license to operate radio technology in almost all juristrictions. However that works more as a barrier for entry to competing companies, than it does as a deterant to criminals.
