"I don't think the public knows how bad things have gotten," said Kathryn Showers, head deputy district attorney of the High Technology Crimes Division. "For example, there is a practice called `war ganging' where if someone has a wireless laptop, they can come and park outside your home, and if you don't have a router on the system to protect transmissions, they can monitor what you are doing and use your IP address to commit crimes."
So, disturbed by this but enlightened, I went out and bought a nice Ryobi 1/4" router at Home Depot, and as soon as I figure out how to plug it into my PC, I'm sure my DSL transmissions will be safe from war gangers committing any crimes.
