Home wi-fi could be hacked in five seconds

Wireless internet networks in millions of homes can be hacked in less than five seconds, a study claims today. The wi-fi hacking means criminals can spy on the activities of families, perhaps stealing their identity and banking details to raid their accounts. The hackers could also use the wi-fi access to tap into illegal pornography or upload and download stolen music and movies without being traced. Security risk: According to new research, a quarter of private wireless networks do not have a password An. ‘ethical hacking’ experiment in six cities, using freely available software, found almost 40,000 home wi-fi networks at high risk. Separately, there are concerns about the security of those who use free wi-fi networks offered by coffee shops and other businesses. The study, commissioned by card protection and insurance firm CPP, highlights a ‘cavalier’ attitude to keeping data safe.
