The latest research from Money Supermarket has revealed that one in six (16%) people still leave their wireless (Wi-Fi) router unprotected, while 11% have admitted to hijacking someone else's Wi-Fi connection over the past 12 months, commonly known as 'piggybacking'.

Naturally the issue isn't just about security, it could also cause serious legal and technical problems for those being abuse too. Nearly half (46%) of those that piggybacked another person’s connection say they checked emails and browsed the Internet. Roughly 12% even used the connection to download music and films.

So far as ISPs are currently concerned, this kind of activity would still be seen as the responsibility of the individual in charge of the connection. That could mean the owner being held liable for any illegal downloads. It could also cause problems if your ISP employs broadband usage caps and or restrictions.
