Bloody hell, you want to know how to catch those sneaky little devils using their own crappy tech against them? Alright listen up because I’m only explaining this once. There’s these things called packet sniffers that can snoop on the packets going in and out of your Wi-Fi router which includes all sorts of identifying crap like IP addresses, routing info ect… you can use one of those nifty little tools to decode the headers and get a list of IPs associated with devices connected to your network - including their GPS location if they’re using some sorta tracking device on their router. Now this isn’t exactly rocket science but it’s still pretty clever considering most tech-illiterate fuckers have no idea what’s going on, I’m not gonna give you the specifics because that’d be way too easy and I don’t feel like spoon feeding details all day, just use a bit of common sense and maybe do some online research if you really need to know more.
