Chrome Extension PAB

Google Workspace Phish Alert Button (PAB) Product Manual

The Phish Alert Button (PAB) Chrome Extension for Google Apps or Google Workspace gives your end-users the ability to report suspicious emails and empowers your employees to take an active role in managing the problem of phishing and other types of malicious emails. The tool can also provide your IT or risk management team with early warning of possible phishing attacks or malicious emails so they may take timely and effective actions to prevent security breaches or network compromise.

Paid Integration: If you are using our full-featured Phishing and Training console, the PAB will also track if your users report our simulated phishing emails, so you can see which users are successfully identifying potentially malicious emails.

We encourage you to inform all of your users of this tool before making it accessible. To help inform your users, here are helpful resources that you can use to assist with the implementation of the PAB:

  2. Hover over the app icon to the left of the PAB Extension ID: hfokdlmjeppdmpbngjpnlnijogcecaop.

User Experience

Once the PAB add-in is installed, upon their next Chrome restart, your users will be prompted with a pop-up message to Allow the KnowBe4 PAB app. They must click Allow on this pop-up message.

After allowing the PAB app, your users will see the PAB as an orange Phish Hook within Gmail.

A user can use the Phish Hook to report any email as a phishing email. The reported email will be in the user's Sent Items as a forwarded message and will be deleted from the user's Inbox. If the user incorrectly reported the email, they can retrieve it from their Deleted items/Trash.

Note: Users cannot use the PAB to report multiple emails at once. However, if an email has multiple emails associated with it, ALL of the emails will be reported when you report the email.
Note: The PAB uses Campaign Recipient ID (CRID) validation to detect whether or not an email that is marked with a training header is a simulated phishing email. If a message has a valid CRID and is reported for the first time (within the past hour) from the same account where the PAB was installed, it will be treated as simulated. A simulated message will be deleted and only shown as reported in the console instead of forwarded to PhishER.

To instruct your users on how to use the PAB, you can provide our How To Use the Phish Alert Button (PAB) in Gmail for Google Chrome article.
