New York case underscores Wi-Fi privacy dangers

Password-protect your wireless router.

It’s unknown how often unsecured routers have brought legal trouble for subscribers. Besides the criminal investigations, the Internet is full of anecdotal accounts of people who've had to fight accusations of illegally downloading music or movies. Whether you’re guilty or not, “you look like the suspect,” said Orin Kerr, a professor at George Washington University Law School, who said that’s just one of many reasons to secure home routers. Experts say the more savvy hackers can go beyond just connecting to the Internet on the host’s dime and monitor Internet activity and steal passwords or other sensitive information. A study released in February provides a sense of how often computer users rely on the generosity — or technological shortcomings — of their neighbors to gain Internet access. The poll conducted for the Wi-Fi Alliance, the industry group that promotes wireless technology standards, found that among 1,054 Americans age 18 and older, 32 percent acknowledged trying to access a Wi-Fi network that wasn't theirs. An estimated 201 million households worldwide use Wi-Fi networks, according to the alliance. The same study, conducted by Wakefield Research, found that 40 percent said they would be more likely to trust someone with their house key than with their Wi-Fi network password. For some, though, leaving their wireless router open to outside use is a philosophical decision, a way of returning the favor for the times they've hopped on to someone else’s network to check e-mail or download directions while away from home . “I think it’s convenient and polite to have an open Wi-Fi network,” said Rebecca Jeschke, whose home signal is accessible to anyone within range. “Public Wi-Fi is for the common good and I'm happy to participate in that — and lots of people are,” said Jeschke, a spokeswoman for the Electronic Frontier Foundation, a San Francisco-based nonprofit that takes on cyberspace civil liberties issues. Experts say wireless routers come with encryption software, but setting it up means a trip to the manual.
