tommyq Posted August 17, 2020 Share Posted August 17, 2020 Hi. I'm trying to devise a means to quite literally find a phone - perhaps in a field etc. I can see with various tools some makes of phones and even detect how far away they are by seeing the signal strength. However, some phones appear to be silent or perhaps are using random MACs? In my use case I wont know the MAC address of the phone so all I need is to know there is one and how far away it is. I appreciate the range is limited, but thats fine. I've seen old and newish Samsung phones get detected while out of range from their APs. Equally, I've seen Huawei not. What happens for the ones that cant be detected away from their home AP is that as they come in range, I suddenly see them. This is with the likes of airodump-ng, kismet, and from gitgub trackerjacker. On the Tetra, I cant see this 2nd class of phone with Recon, signal strength or site survey modules. I'd tried to use the Tetra with the likes of airodump-ng in parallel to get get the Tetra to respond to probe requests. My assumption if the phone isn't using random MACs is that it is in fact silent until the AP reaches out 1st. Does anybody have any thoughts or way of detecting such devices. My remaining idea is to simply try to detect any 2.4G signals emanating from the phones. Thanks. Quote Link to comment Share on other sites More sharing options...
