Oregon FBI’s Tech Tuesday: Building a digital defense against unwanted cookies

Oregon FBI

This week marks Data Privacy Week – a national and international effort to teach consumers and businesses how to better manage personal information and keep it secure. In honor of that - this week's Tech Tuesday focuses on privacy matters related to internet tracking.

Welcome to the Oregon FBI’s Tech Tuesday segment. Today: Building a digital defense by cracking the cookie code.  

Unfortunately, we are not talking about chocolate chip or even snickerdoodle varieties. We are talking about the kind of cookie that follows you around the internet. 

Our partners at the Federal Trade Commission explain it well: 

When you visit a website, that site might place a file called a cookie on your browser. Websites use cookies to customize your browsing experience. When a website you visit places a cookie on your browser, that’s a first-party cookie. Examples include: 

  • A news website shows local weather and stories about topics you’re interested in. 
  • A website remembers your username or items you left in your shopping cart. 

The websites you visit often allow other companies to place cookies as well — for example, to deliver ads targeted to you. These are third-party cookies. Here’s an example of a third-party cookie: 

  • An advertising company places a cookie and sees that you visited a website about running. It then shows you an ad for running shoes when you visit other sites. 

Ready to go on a cookie diet? You can choose to have more privacy when you go online by adjusting the privacy settings on the browsers you use. These settings let you do things like:

  • see what cookies are on your computer and delete them 
  • decide what type of cookies you want to allow, including tailoring those settings by website 
  • turn on private browsing mode 

If you clear your cookies instead of blocking them, they’ll be set again when you browse, so you may need to clear them from time to time. 

This FTC webpage walks you through how to make changes on some of the most common browsers. 

If you are the victim of an online fraud, you should report the incident to the FBI’s Internet Crime Complaint Center at or call your FBI local office.
