Internet Privacy & Website Tracking
Yesterday you emailed a friend to tell them about how much the kids love
the new swimming pool, and today every ad on Facebook is trying to sell you
inflatable rafts.
What’s going on here?
How did they KNOW?
If you’re a little creeped out about these eerily specific ads you’re not alone.
Privacy advocates are worried about website tracking too, and they have
their eye on the main culprit: cookies!

Cookies go back to the early days of the World Wide
Web. In 1994, developers at Netscape were trying to
figure out how to make online shopping work. The
website needed a way to “remember” who the
customer was and what they wanted to buy.
Thus, the web cookie was born.
Cookies: Delicious or Evil?
Without cookies, the internet as we know it simply
would not function. There is nothing good or evil
(or yummy) about them; they are just tools.

First-party cookies
• Are “set” by the website you are visiting.
• Used for basic functions, such as remembering your
preferences.
• Keeps track of how many times you’ve visited the page.
• Once you leave the webpage, the first-party cookie has
nothing left to do.
First-Party vs Third-Party Cookies

Third-party cookies
• Are set by a different webpage than the one you are visiting.
• The sources are often advertisements or widgets.
• Are used to track you across multiple websites and monitor your
views, clicks, and anything else that might be relevant for
marketing analysis.
• The third-party cookie can spy on you from ANY website that
displays an ad or widget from the same domain that set it in the
first place.
• This information is collected by the advertiser to construct a
picture about who you are and what you like.

Third-Party Cookies
Blocking Third-Party Cookies
Firefox
Tools > Options > Privacy
Uncheck "Accept third-party
cookies.”
Google Chrome
Settings>Advanced
Settings>Privacy>Content Settings
Check “Block third-party cookies and
site data.”
Internet Explorer 11
Tools > Internet Options > Privacy >
Advanced
Check “Override automatic cookie
handling, and then choose “Block”
under “Third-party Cookies.”
Removing Third-Party Cookies
By far the easiest way to delete third-party
cookies is to use a free piece of software
called CCleaner. It is a well-known, reputable
program with many other useful features
tuning-up your PC. And best of all, it’s FREE!
Click Download
Check “Cookies” for each browser you
use
Click “Analyze” and review the results
Then click “Run Cleaner”

There is a more persistent cookie variety that is
hard to find and remove: the “zombie cookie.”
In addition to setting typical cookies, it also sets a
“Flash cookie.”
This cookie is stored in the Adobe® Flash directory
rather than your internet browser folder.
Mutant Cookies From
Beyond the Grave?
8. © 2016 eSOZO Computer & Network Services • www.esozo.com
It works like this:
The third-party sets two standard cookies, plus one Flash
cookie.
Every time you visit a webpage, the Flash cookie checks
to make sure the standard cookies are present.
If it doesn’t find them (i.e. if you have deleted the
cookies), it recreates them!
The outcome of this is a cookie that can’t be deleted; it
keeps returning from “the dead,” again and again.
Mutant Cookies From
Beyond the Grave?
The solution? Identify and delete the Flash cookie as well.

To destroy this undead
monster, we turn once
again to CCleaner.
This time, click Cleaner and
select the Applications tab
Then check “Adobe Flash
Player” under the Multimedia
section
Click “Analyze” and “Run
Cleaner” to remove the flash
cookies
