Geo-Spoof

What is this?

This is a geological location spoofer extension for Chromium browsers

What makes this different from others?

Most all geographical location spoofers can easily be detected by one of many different methods

Detection Methods

This section contains a couple of the methods I have personally discovered to work in detecting Geolocation spoofing. Note that this is not a comprehensive list and there may be more methods out there that I am not aware of.

InstanceOf Method

let layer1 = navigator.geolocation;
if (!layer1 instanceof Geolocation) {
    console.warn("Layer 1 does not match the correct class!");
}
layer1.getCurrentPosition((layer2)=>{
    if (!layer2 instanceof GeolocationPosition) {
        console.warn("Layer 2 does not match the correct class!");
    }
    const layer3 = layer2.coords;
    if (!layer3 instanceof GeolocationCoordinates) {
        console.warn("Layer 3 does not match the correct class!");
    }
})

Prototype Method

if (Object.getPrototypeOf(navigator.geolocation).toString() !== "[object Geolocation]") {
    console.warn("Layer 1 failed prototype check!")
}

let prototypes = [
    Object.getPrototypeOf(navigator.geolocation.toString).toString(),
    Object.getPrototypeOf(navigator.geolocation.getCurrentPosition).toString(),
    Object.getPrototypeOf(
        navigator.geolocation.getCurrentPosition.toString
    ).toString(),
];

for (const i in prototypes) {
    const proto = prototypes[i]
    if (proto !== "function () { [native code] }") {
        console.warn("Function failed prototype check!")
    }
}

navigator.geolocation.getCurrentPosition(function (layer2) {
    if (Object.getPrototypeOf(layer2).toString() !== "[object GeolocationPosition]") {
        console.warn("Layer 2 failed prototype check!")
    }
});

Function ToString Method

if (navigator.geolocation.getCurrentPosition.toString() !== "function getCurrentPosition() { [native code] }") {
    console.warn("ToString check failed on root function!")
}
let last = navigator.geolocation.getCurrentPosition.toString
for (i=0;i<=100;i++) {
    if (last.toString() !== "function toString() { [native code] }") {
        console.warn(`ToString recursive check failed at iteration #${i}!`)
    }
    last = last.toString
}
