Think before you click

More and more legitimate-looking “advertising” on major websites turns out to be malicious. Criminals pay for and post ads to try to get you to click on them so they can direct you to a compromised website. Compromised websites can infect your computer with ransomware. Or they may display popups that claim your computer has a virus and tell you to dial a toll-free number to “fix” your computer, and then they’ll claim to be Microsoft technical support and ask for your credit card information.

This exploit was recently found on Comcast’s Xfinity website, where a malicious ad claimed to compare Direct TV to Comcast. Users who clicked on the ad were directed to a site that installed malicious software on all computers that weren’t protected against that kind of attack.

What should you do? Stay vigilant when you’re online, keep your security systems up to date, and think before you click.

The Information Technology Department updates your work computer with the latest versions of software, but you need to update any other devices you use as well as the applications and operating systems you use at home.
