Drive-By Hacking With A Can Shows Huge Security Problems
An experiment carried out in London, UK, has shown just how bad security of wireless networks is among commercial companies there.
Using a can to make an antenna, drive by hackers found over 60 wireless networks in companies that are in no way secure, in only 30 minutes. Other studies have shown around 67% of companies do not even have simple security processes in place.
Security companies say "Many companies are going out and buying a wireless access point to see what it can do. The problem is that they have opened a great big back door into their network."
