More than half of computer users have illegally logged on to someone else’s wi-fi connection yet only 11 people have been arrested for the crime, an investigation by The Times has found.”Wi-fi tapping” or “piggybacking” has boomed in the past few years as hackers take advantage of unsecured computers to access the internet without paying for it.Police regard it as a serious offence because intruders can download pornographic materials and illegal images without being caught.
