I read an article on the New Straits Times Online yesterday on DNS poisoning and it mentions that it is a step up from phishing. While we have a slight control over email phishing and all we have to do to safeguard our information is not to simply click on any link that come in via email, Private Message or Instant Message, for DNS poisoning, many people would unsuspectingly surf on replica websites because the DNS servers have been changed by hijackers. That is certainly scary and dangerous, isn’t it?
Also, I am glad to be reminded that free public wi-fi is great, like the Penang state-wide wi-fi project that I mentioned in my previous post, we really have to be extra careful using free wi-fi which is not password locked. Never use free wi-fi to surf financial websites or websites that require you to disclose personal and sensitive over the web. You would be better off performing internet banking or online transactions in a secure environment like your home.
