Submission + - Rayhunter: A New Tool from EFF to Detect Cellular Spying (androidauthority.com)

Rayhunter uses an open-source software package designed to look for evidence of IMSI catchers in action, running on an old Orbic Speed RC400L mobile hotspot. The great thing about that choice is that you can pick one up for practically nothing — we’re seeing them listed for barely over $10 on Amazon, and you can find them even cheaper on eBay.

There’s an installation script for Macs and Linux to automate getting set up, but once the Orbic is flashed with the Rayhunter software, it should be ready go, collecting data about sketchy-looking “cell towers” it picks up.

Right now, much of the use of IMSI catchers is still shrouded in mystery, with the groups who regularly employ them extremely hesitant to disclose their methods. As a result, a big focus of this EFF project is just getting more info on how and where these are actually used, giving protestors a better sense of the steps they’ll need to take if they want to protect their privacy.

Comment 31-bit date? (Score 4, Interesting) 29

Grasping for straws here, but if Garmin used a signed 31-bit integer for their smartwatch date processing, and they used an epoch of January 19, 1991, it would overflow right about now... coincidentally they set up their first dedicated manufacturing facility and sold their first product to the US Army in 1991.

Heuristics are bug ridden by definition. If they didn't have bugs, then they'd be algorithms.
