Hey, Windows user- if you haven’t made sure you’re running the latest version of Internet Explorer, do it now. If you’re lacking the motivation, take a look at this video that shows just what might happen to you if you were to misspell google.com. Scary. (See a blog posting about this video here. Note that the link to the video on that site is currently broken.)
You also can't always trust websites that you normally trust. A few days before the Super Bowl, the official website of Dolphin Stadium was hacked (that's where the Super Bowl was held). Website visitors running Windows might have been infected with a Trojan keylogger/backdoor if they hadn't already installed a couple of Windows security patches.
And if you’re thinking you’re safe from attack just because you’re running some other OS, take a look at this recent report: Some researchers set up 4 Linux boxes and watched as the servers were attacked on average once every 39 seconds. The hackers most often attempted to access the machines with user names of "root" and "admin" using passwords which were variations of the user name or "123." Man, I thought I was the only one using 123...
Another recent study states that 70% of websites are at immediate risk of being hacked! Well, maybe that number is a little high. But the point is, if you are on the Internet, you better watch out. Have a nice day.
