Carey Smith is the founder of Big Ass Fans, a company that sells industrial, commercial and residential fans.He started working at age 9 and never stopped, gaining a tireless work ethic as he sold shoes and Christmas cards, changed bedpans and newspaper type, and washed shirts and floors. He hopes Big Ass Fans can become a 200-year company that acts in the long-term interests of its customers, employees and suppliers.If you’ve recently found your web browsing plagued by pornographic pop-ups and irritating adverts, there might be a simple – but dangerous – explanation. Security researchers at Ara Labs have warned of an active campaign which has seen attackers changing DNS settings on routers, causing unauthorised ads and adult content to appear on virtually all websites affected users visit, generating income for the attackers.DNS records work like a telephone book, converting human-readable website names like or into a sequence of numbers understandable by the internet.Websites like Twitter, Netflix and Paypal have become the essential building blocks of digital life.
It’s easy to imagine such a technique being deployed to dupe users into believing that they are visiting online genuine banking websites, but Ara Labs is reporting that this latest attack is exploiting the fact that so many websites on the internet run a Google Analytics script to measure and track visitor traffic.
Step 1: Unplug it The quickest and easiest way to make sure your external webcam can’t be used to spy on you is to disconnect it either from your computer, or the mains.
Without power, a webcam won’t work, so if you’re not using it, keep it unplugged.
Step 2: Change the password Passwords are usually the weak spot of any supposedly secure system and webcams are no different.
A webcam that connects directly to a wi-fi network (usually called IP cams) will have a video feed and settings page that’s protected by a username and password.
