The Floor Plan: A Map for Modern Heists

Your Home’s Layout is Publicly Available—Here’s Why That’s Dangerous

In our previous guide, we discussed how car thieves use "Relay Attacks" to steal keyless vehicles. But there is a missing link: How do they know exactly where to stand to pick up your key’s signal? The answer lies in your floor plan, which is likely still floating around on Australian property sites.

A GPS for Car Thieves

A relay attack works by amplifying the signal from your key fob inside your house. If a thief knows your floor plan, they don't have to guess where your keys are. They can see the "entryway nook" or the "kitchen island" on the diagram and walk directly to the corresponding exterior wall with their amplifier. By knowing the thickness of your walls and the layout of your foyer, they can execute a car theft in under 60 seconds without ever touching your door.

The "Invisible" Security Threat

Floor plans reveal more than just room sizes. They show:

• The "Core" of the Home: Where people naturally congregate and leave valuables.
• Internal Access Points: How the garage connects to the living area.
• Privacy Vulnerabilities: Which bathrooms or bedrooms are visible from specific exterior vantage points.

Why DIY Removal Isn't Enough

Many homeowners try to email sites like Domain or RealEstate.com.au themselves, only to be met with automated "no" responses or told that the data belongs to the agent. Because these floor plans are often indexed by "shadow" sites and data brokers, the "ghost" of your floor plan can haunt the web for decades.
