CHAPTER SEVEN
Pay Up or Else!
The nightmare began online and ended with federal agents
storming a house in suburban Blaine, Minnesota. The agents had onlyy an IP
address associated with child pornographyy downloads and even a death
threat against Vice President Joe Biden. Byy contacting the Internet service
provider associated with that IP address, the agents acquired the user’s
phyysical address. That sort of tracking was veryy successful back in the dayys
when everyyone still had a wired connection to their modems or routers. At
that time, each IP address could be phyysicallyy traced to a given machine.
But todayy most people use wireless connections within their homes.
Wireless allows everyyone inside to move around the house with mobile
devices and remain connected to the Internet. And if yyou’re not careful, it
also allows neighbors to access that same signal. In this case the federal
agents stormed the wrong house in Minnesota. Theyy reallyy wanted the
house next door to it.
In 2010, Barryy Vincent Ardolf pleaded guiltyy to charges of hacking,
identityy theft, possession of child pornographyy, and making threats against
Vice President Biden. Court records show that the trouble between Ardolf
and his neighbor began when the neighbor, who was in fact a lawyyer and
was not named, filed a police report sayying that Ardolf allegedlyy
“inappropriatelyy touched and kissed” the lawyyer’s toddler on the mouth. 1
Ardolf then used the IP address of his neighbor’s wireless home router
