If you’re running a wireless network at home it’s always a good idea to enable WEP (Wired Equivalent Privacy). If not enabled, of if enabled with an easily guessable password, anyone who can get within range of your access point will be able to access your network. This could allow them the ability to access network shares on your PCs (if you have any enabled) or even for them to use your broadband connection.
While it’s tempting to think that having someone “borrow” your broadband connection is relatively harmless, consider this.
Wireless security for home networks is in the spotlight following an unusual arrest in Canada, where a man stands accused of downloading child pornography over a hijacked Wi-Fi connection.
Toronto police said they stopped a car last week for a traffic infraction when they found the driver naked from the waist down with a laptop computer on the front seat, playing a pornographic video that had apparently been streamed over a residential wireless hot spot. The driver was charged with possession, distribution and creation of child pornography, as well as theft of telecommunications—a first in Canada, according to local authorities.
If the “authorities” decided to trace your broadband usage, it would be difficult for you to prove that you didn’t access the child porn site (although forensic analysis of your computer would not show any evidence that you accessed it, that wouldn’t necessarily exonorate you, since they’d have evidence to show that the stream came through your router).
While it wouldn’t land you in jail and get you listed as a sex offender, another possible problem would be if a wardriver used your connection to send spam. Since almost every ISP outlaws spam as part of their AUP (Acceptable Use Policy), and the spam would have your IP address on it, they’d just assume that you sent it and cancel your account. You would have a difficult time proving otherwise, unless the spammer was caught in the act (and they’re a lot less likely to be sitting outside your house with their pants down
).
