The Wi-Fi Hacking Neighbor From Hell

Hugh Pickens writes "Barry Ardolf, a Minnesota hacker prosecutors described as a 'depraved criminal,' has been handed an 18-year prison term for unleashing a vendetta of cyberterror that turned his neighbors' lives into a living nightmare. Ardolf hacked into his next-door neighbors' Wi-Fi network and used it to try and frame them for child pornography, sexual harassment, various kinds of professional misconduct, and to send threatening e-mail to politicians, including Vice President Joe Biden. The bizarre tale began in 2009 when Matt and Bethany Kostolnik moved into the house next door to Ardolf. On their first day at their new home, the Kostolnik's then-4-year-old son wandered near Ardolf's house. While carrying him back next door, Ardolf allegedly kissed the boy on the lips. 'We've just moved next door to a pedophile,' Mrs. Kostolnik told her husband. The couple reported Ardolf to the police, angering their creepy new neighbor (PDF). 'I decided to "get even" by launching computer attacks against him,' said Ardolf, who downloaded Wi-Fi hacking software and spent two weeks cracking the Kostolnik's WEP encryption. Then he used their own Wi-Fi network to create a fake MySpace page for the husband, where he posted a picture of a pubescent girl having sex with two young boys. Ardolf turned down a 2-year plea agreement last year to charges related to the Biden e-mail. After that, the authorities piled on more charges, including identity theft and two kiddie-porn accusations carrying lifetime sex-offender registration requirements."

      Reading the TFA from ars, the reason why he was caught was because he wasn't clever at all:

      1) The only reason why he was caught is because his malicious actions were intertwined with his normal web traffic (his name in plain text and Comcast packets). He could have used a clean purpose-built computer for his torture, like a laptop, that wasn't configured for his own network at all, and hid it in a safe deposit box or something and they never would have figured out where it's coming from without a long and arduous task with a spectrum analyzer.

      2) Ardolf did so much stuff on the target network that it raised suspicion. It's the same thing that happens to regular criminals: they get greedy and keep coming back for more. If he just went right for the terrorist threats and never ever connected again, his neighbors would never have had any reason to suspect external hacking. Even then, his prank emails to coworkers and social network profiles were so out there that they were obvious. There must have been many more subtle ways to do damage that aren't immediately obvious.

      3) The neighbor works for a law firm and they were willing to spend the resources to check out his home network and find the unknown device as well as install a sniffer.

    And the problems we see these days are only made worse by current marketing and advertising trends, increased paranoia and a general failure to address causes and sources.

I speak of persecution of muslims and other non-christians, homosexuals and communist party members.

    It is when paedophiles have a fear if getting caught and persecuted that they are moved from touching children to killing them after being unable to control their impulses. I believe if these troubled individuals were allowed to deal with their problems in a way that does not immediately ruin their lives (which is not really an option which is presently available) we would see a great deal less of the tragedies we have seen over the years.

When alcohol was criminalized, birth was given to massive organized crime and violence. And the "war on drugs" helps keep all sorts of organized crime and violence alive and well.

    Plug a *real* router in there somewhere so that such things can be monitored and logged and/or you can VPN over your own internal Wifi link so that even someone having complete access to your wireless isn't a problem at all. Then you don't even *need* wifi encryption turned on at all (but it's a good hindrance to any intruders) and you can play games like upside-down-ternet with people who try to get a free ride on your connection.

    That's the setup I had - just had a WPA network (WPA2 wasn't around at the time) and didn't trust WEP or (correctly, it seems now) WPA to secure my network. So I just made the wireless access point be an "untrusted" network, as it should be, on my main Linux router - which did the actual connection to the Internet and offering IP's etc.

I surfed, and my guests minds were blown that even after I'd told them the WPA password and they'd joined the wireless network they couldn't "see" anything at all.

    This also lets you block EVERYTHING coming in via wifi to your laptop except for that OpenVPN port with a decent software firewall, which means you don't have to worry about something accessing filesharing ports, or tapping into whatever junk services your PC's are exposing to the whole wifi network (which, incidentally, can save a lot of bandwidth).
