Apple Air Tags

Not quite. They are not hacked AirTags. Some one buys an AirTag and syncs it to their phone. They then somehow hide it on you or your car or anything else. Perhaps dropping it in a coat pocket or attaching it to your car. This is not YOUR AirTag it is THEIR AirTag that reports back to them.
The software fix that Apple implemented sends you a message if an air tag that isn’t yours remains in proximity to you. This would work if you have an iPhone not sure,if it works for an Android phone.
