For years I have been telling people to be especially careful when they venture into the dark back alleys of the Internet. My thinking was that these more "wild west" areas would be home to most of the malware and other attacks.
Dark Reading analyzes a Cisco report which says that online shopping sites and search engines are over 20 times more likely to deliver malware than counterfeit software sites. Advertisers are 182 times more dangerous than pornography sites.
So, I guess I need to change my tune. Be careful when you are going about your daily business, and have fun in those dark alleys!
