The article covers that under the section "detection".
TL;DR: You can easily detect it while it communicates via GSM, and the device is also shielded quite badly, resulting in lots of easily detectable RF interference while it works.
All you need is a cheap RF detector. Having access to a full spectrum analyzer or a SDR will make this even easier.
All this gets much harder while the thing lies dormant, waiting for noise activation or commands. So the "quick bug sweeps" you see in the movies are more difficult.
- Cthulhu_ 2y agoWe used to have keychain lights that would start to blink whenever a nearby phone went off, I can imagine it could be set off by a device like this lol.
- ChrisMarshallNY 2y ago> So the "quick bug sweeps" you see in the movies are more difficult. Not if the sweepers are talkative (assuming that the device is sound-activated).
- alexey-salmin 2y agoGood ones record long spans of audio, then transmit them in short infrequent bursts outside of working hours. You can leave GSM recording equipment overnight and analyze logs, but even when you see it in the logs it'll be hard to locate the device physically when it's not transmitting.
