AuntieTuna is a browser extension that checks if each page you visit is a potential phishing website, based on snapshots of known-good websites.
For example, as a customer of PayPal, you add a snapshot of the
www.paypal.com
login to your known-good.
AuntieTuna then checks if every other page you visit looks like
www.paypal.com
.
If the page does, then AuntieTuna marks it as suspected phish.
We will do the following with AuntieTuna (10-15 min.):
The walkthrough steps are same or very close to Google Chrome. While most of the screenshots are of Mozilla Firefox, they should look similar to what you will see in Google Chrome, too.
Chromium / Chrome / Brave: Install AuntieTuna: Go to Chrome Web Store and install by clicking on the blue “Add to Chrome”. You can also sideload the extension by following these instructions.
AuntieTuna will ask for permissions (your browsing history or data is not collected in AuntieTuna: learn more). Click on “Add Extension”:
After installation, the browser will give you a notification that it has been successfully added:
Firefox: Install AuntieTuna: Go to https://auntietuna.ant.isi.edu and click on “auntietuna-0.0.x-fx.xpi” (blue box in the next picture):
You’ll be asked for permission to install an add-on. Click on “Continue to Installation”:
AuntieTuna will ask for permissions (your browsing history or data is not collected in AuntieTuna: learn more). Click on “Add”:
Chromium / Chrome / Brave and Firefox:
After installation, the Options page might open. You can close this
for now and continue with the next step:
If you want to know more:
The options page is where you can import your Known-Good
Lists (“Import Known-Good Lists”) and manage/export your
Known-Good Lists (“Manage and Export Known-Good Lists”).
“Manage and Export Known-Good Lists” shows the list of sites you
are protected on.
Currently by default, you are protected on USC’s Single-Sign On
portal (2019), PayPal (2015), and the EICAR test.
Test AuntieTuna: Try visiting a “phishing” page
by clicking on this link:
https://auntietuna.ant.isi.edu/eicar.html.
(This page isn’t actually a phish: it just contains a
test string
that we’re looking for).
You should see something like this next image:
This image shows the alert you’ll see when AuntieTuna
suspects that a visited page is phish.
Since we’re in alpha, the alert is not very prominent. There’s also
some debugging information at the bottom that you can
submit that will be very
helpful for the developers.
Inoculate with AuntieTuna: let’s see how AuntieTuna protects us
from PayPal phish by adding www.paypal.com
to our known-good.
Visit https://www.paypal.com/us/signin, then click on the
red shield (top right), and then click on the green “Add to Good
List”:
You’re now inoculated with www.paypal.com
: AuntieTuna will always
check in the background if any page you visit other than
www.paypal.com
looks like the PayPal login. If it does,
AuntieTuna will suspect that it’s phish, and alert you.
Share Your Known-Good: Open the “Options” page by clicking on the
red shield and then clicking on the orange “Options” button:
You can see in “Manage and Export Known-Good Lists” that
www.paypal.com
has its own entry (row #4):
We can “export” this known-good list to share with our friends, so
that they are also protected on PayPal. First click on the checkbox
in row #4, then click on “Export Selected”:
You can then download and share the resulting known-good list
(.json
file) directly via email, or through our website:
Use Others’ Known-Good: Let’s now import facebook.com
's
known-good. First, save the following file to your computer:
hashes.facebook-2019-10-15.json
or download it from Known-Good Lists.
Drag and drop the hashes.facebook-2019-10-15.json
file inside
the blue dashed box, or click on “Browse” and find the file:
If the import is successful, you’ll see a message saying that the
file was successfully imported, and a new entry (row #5) in your
known-good list:
You can use these instructions to import known-good lists from your
friends, or from this website.
We’re done! AuntieTuna is now silently protecting you from phishing
sites that copy from www.paypal.com
, shibboleth.usc.edu
(USC’s
Single Sign-On portal), and facebook.com
.
Next, try the following:
