A federal agent with the Department of Homeland Security called for help last year. A friend working in another part of government was worried that someone might have been following them when they met a confidential source. Their source's cover might have been blown if they were being followed. It was a very important matter of life and death.

There are detection routes if you want to know if you're being followed. Changing lanes on a freeway is one of the things you can do if you drive. It is possible that a car is following you. It didn't feel right. He was just looking for an electronic supplement. He was concerned about the confidentiality of the confidential person.

Edmondson, a hacker and digital forensics expert, decided to build his own anti- tracking tool after failing to find any existing tools that could help. If the same phone is spotted multiple times within the past 20 minutes, the system will alert you. It can alert you if you are being followed. The research project will be presented at the Black Hat security conference in Las Vegas this week and was built using parts that cost less than $200. The underlying code is open-sourced by him.

There has been an increase in the number of ways that people can be tracked. Either software or hardware can be used for tracking. Stalkerware that can be installed directly on people's phones can give attackers access to all your location data, messages, photos, videos, and more, while physical trackers have been used to track where people are in real time Some anti- tracking tools have been added by Apple.

There are a lot of tracking tools that are easy to purchase. There is so much that can be done to spy on people, and so little that can be done to help them.

The homemade system works by scanning for wireless devices around it and then checking its logs to see if they were present within the last 20 minutes. It was intended to be used when people are on the move rather than sitting in a coffee shop.

A few components make up the anti- tracking tool. A portable charge powers the system, a small waterproof case protects the device, and a wi-fi card is used to look for nearby devices. The device shows the notifications on the screen. It is possible that each alert is a sign that you are being followed.
