Second Chance Product Manual

Second Chance is a tool for Outlook and Microsoft 365 (formerly Office 365) which prompts your users before they visit a potentially unsafe or unknown website. Users who click on URLs in their email, or on URLs located within attachments downloaded from their email, will be prompted by Second Chance and can choose to either "continue" to the website or "abort" their action. Aborting the action could provide your user a "second chance" to avoid a malware infection from a dangerous website.

Second Chance can be installed on a per-client basis or deployed through Group Policy (GPO). You can decide what URLs are "safe" to visit in your organization--these URLs you define will not trigger a prompt window to appear.

It is important to note that Second Chance is not an endpoint protection tool--it is a user behavior analysis and security awareness training tool. Should a user click on a link in their email or a link within an attachment they’ve downloaded from their email, the prompt they receive will be a "second chance" for your users to think twice before they navigate to a potentially dangerous site.

Settings

The Settings tab allows you to customize the content of your prompt messages and manage your "No Prompt" Domains.

 

Prompt Settings

The Prompt Settings area allows you to alter the content of your prompts and modify additional prompt settings.

Before installing, we recommend you consider what content you'd like to include in the prompt messages that appear when your users click on links in their email or within attachments they've previewed or opened from their email.

If you're not ready to do this before installation, remember that you can update the prompt content at any time and the next prompt your users see will match your current settings.

Second Chance will trigger four different types of prompts:

1. General Prompt: For general URLs which have not been added to the No Prompt Domain list.
2. Punycode Prompt: For Punycode links.
3. Attachment Prompt: For links clicked within attachments that have been downloaded from email.
4. URL Unwinding Prompt: For rewritten or shortened URLs.

To edit the content of the prompts, click on SECOND CHANCE at the top of your screen, then click the Settings tab.

 

General Prompt Text

In this area, you can modify the Message Banner, Message Prompt, Continue button, and Abort button. This text will appear on all Second Chance prompts.

Message Banner: This is the banner at the top of the prompt (maximum of 30 characters). 

Message Prompt: This text can serve as a reminder to the user to consider where the link is taking them and to check for red flags (maximum of 255 characters).

Abort Button: This button allows the user to cancel their current action and not visit the link they just clicked on (maximum of 40 characters).

Continue Button: This button allows the user to move forward with their action and visit the link they just clicked on (maximum of 40 characters).

Example of General Prompt:

Punycode Prompt Text

In this area, you can modify the Punycode Description, which indicates that Punycode was detected within this particular link. This text will only appear on the Punycode prompt.

Example of Punycode Prompt:

Attachment Prompt Text

In this area, you can modify the Attachment Description, which indicates that this link was clicked on from an attachment the user downloaded or previewed from their email. This text will only appear on the Attachment prompt.

Example of Attachment Prompt:

URL Unwinding

In this area, you can modify the URL Unwinding Description, which indicates that this was a rewritten or shortened URL. The prompt will decode or unwind the clicked URL to display the actual destination. This text will only appear on the URL Unwinding prompt.

Decode Shortened URLs: This setting will unwind URLs that have been shortened through the use of common URL shortening services. For a list of all supported URL shorteners, click here.

Decode Rewritten URLs: This setting will unwind URLs that have been rewritten by your mail or security environment. For a list of all supported URL rewriters, click here.

Example of URL Unwinding Prompt:

Additional Prompt Settings

The three available Additional Prompt Settings will modify when and if Second Chance prompts appear for specific types of links. These settings are checked "on" by default. A description of each is below:

Do Not Prompt on Internal Links:
This will enable/disable prompts on links that appear to be navigating to your internal network (non-routable domains).

Do Not Prompt on KnowBe4 Phishing and Training Links:
This will enable/disable prompts for KnowBe4's set of phish domains. Enabling this setting means that your users will not receive prompts when clicking phishing links within KnowBe4 phishing tests.

Note: If you check "Use KnowBe4's 'No Prompt Domains' List", this will automatically prevent prompts on KnowBe4's phishing and training links by default. 

Use KnowBe4's "No Prompt Domains" List:
This will enable/disable prompts for domains that exist on KnowBe4's "No Prompt Domains" list. This list contains sites that are deemed to be safe, do not have a history of being exploited by attackers, and likely do not pose a risk to your users.

Note: By default, if you check this box, you will also disable prompting for any KnowBe4 phishing and training links.

Back to top

 

No Prompt Domains

Beneath the Settings tab, you can click on ”No Prompt Domains” to define what URLs should not receive Second Chance prompts. Here, you'll see a list of the No Prompt Domains you've already added. Any URLs with domains matching your "No Prompt" Domains will not be prompted by Second Chance.

No Prompt Domains can be websites that your employees need to frequently access to meet the needs of their job responsibilities or any other websites that you deem to be appropriate for your organization. You can add up to 1,000 domains.

There are two ways to enter the URLs:

1. Add individual domain:
   This will add a single domain to your No Prompt Domains list. Domains you add must be in proper domain format (Example: sub.domain.net, internet.co, knowbe4.com).
   
2. Upload a CSV file:
   This method allows you to import multiple domains at once by uploading a CSV file (.csv). The .csv file you upload must have a header of Domain. Beneath the Domain header, you should add a single domain to each cell, line by line. Domains you add to this .csv must be in proper domain format (Example: sub.domain.net, internet.co, knowbe4.com).
   
   Note that enabling the "Replace all" checkbox will replace all of your current No Prompt Domains with your newly-uploaded .csv.

Installation Methods

There are three main installation methods for Second Chance. As a best practice, we recommend installing Second Chance on a single machine to review its functionality prior to deploying to the rest of your organization.  

 

A) Standard Installation

This method will install Second Chance on a per client basis.

1. Log in to your KnowBe4 console and click the Second Chance tab.
2. Download the Second Chance Training Device Installer (SecondChanceSetup.exe file).
3. Open the installer file you just downloaded and follow the installation steps as prompted.
• Accept the Second Chance License Agreement and click Install.
• Enter your license key when prompted.
• Click Finish to complete the installation.
4. To test that the installation was successful: Open the mail client on the machine where you installed Second Chance. Click on a link within an email and make sure you're receiving Second Chance prompts.

 

B) Command-line Installation

This method will install Second Chance on a per client basis by using a command-line.

1. Download and Save the Second Chance Training Device Installer (SecondChanceSetup.exe file) located beneath the Overview tab.
2. Open an elevated Command Prompt window (Run Command Prompt as an administrator).
3. In the Command Prompt window, navigate to the folder where you saved the Training Device Installer.
4. Enter the following command, then hit Enter:
   Note: Edit the red fields below to match the name of the SecondChanceSetup.exe installation file you downloaded as well as your license key.
   SecondChanceSetup.exe /q /ComponentArgs "KnowBe4 Second Chance":"LICENSEKEY=""XXXXXXXXXX"""
   

   Alternatively, you have the option to install Second Chance with a proxy using the following command:

   SecondChanceSetup.exe /q /ComponentArgs "KnowBe4 Second Chance":"LICENSEKEY=""XXXXXXXXXX"" PROXYSERVER=""hostname:port"""
   Note: Enter in your hostname and port.
5. Open the mail client on the machine where you installed Second Chance.

6. Click on a link within an email and make sure you're receiving Second Chance prompts.

 

C) Group Policy (GPO) Installation

This method will allow you to deploy Second Chance to specific organizational units (OUs) or your entire organization.

Note that we strongly recommend testing the below Group Policy on a single machine before deploying to your entire domain. To do this, you'll want to create and link your GPO to a test OU, containing the machine that you'd like to test Second Chance on, rather than link it to your domain, steps 6-7 below.

1. Log in to your server as an Administrator.
2. Create a shared folder on your domain.
   • Right-click the folder and open Properties.
   • Under the Security tab, add Domain Computers with "Read" permissions.
   • Make sure you have "Write" permissions on the folder and that SYSTEM has "Read & Execute" permissions.
3. Download and Save the Second Chance Installer (SecondChanceSetup.exe file) to your shared folder.
4. Create a .bat (batch) file within the shared folder using the following lines:
   NOTE: Edit the red fields below to match the location of the shared drive where you saved the SecondChanceSetup.exe installation file as well as your license key. 
   copy /B /Y "\\NetworkPath\Name of Shared Folder\SecondChanceSetup.exe" "%TEMP%\SecondChanceSetup.exe"

"%TEMP%\SecondChanceSetup.exe" /q /ComponentArgs "KnowBe4 Second Chance":"LICENSEKEY=XXXXXXXXXX"""

    

   Alternatively, if you have a proxy server filtering outbound traffic, you can specify the proxy server within the .bat file using the following lines:
   copy /B /Y "\\NetworkPath\Name of Shared Folder\SecondChanceSetup.exe"
"%TEMP%\SecondChanceSetup.exe"

"%TEMP%\SecondChanceSetup.exe" /q /ComponentArgs "KnowBe4 Second Chance":"LICENSEKEY=""XXXXXXXXXX"" PROXYSERVER=""hostname:port"""
   
   

   Note:

   Second Chance is proxy-aware and will try to connect to the internet with the proxy server specified for the local user's account. If your proxy is configured in a manner that Second Chance cannot automatically detect, you can use this PROXYSERVER switch during installation to manually specify the proxy server Second Chance will use to connect to the internet.

5. Save the .bat file in the shared folder you created. The shared folder should now contain the .exe file and the .bat file.
6. Next, we'll create a Group Policy. Open the Group Policy Management Tool (gpmc.msc).
7. Open the Forest and Domains drop-down and then right-click your domain (Example: Domain.local or Domain.com).
   These instructions deploy to your whole domain--we recommend testing this GPO on a single test OU (with a single test device placed within that OU) to see how it works.
8. Click Create a GPO in this domain, and Link it here...
9. Name your GPO and click OK.
10. Your new GPO will appear in the list. Right-click and select Edit...
11. From the drop-down menu, select Computer Configuration -> Policies -> Windows Settings -> click Scripts.
12. Double-click Startup Scripts to bring up Startup Properties.
13. Click Add... under the Script tab to open the Add a Script window.
14. Click Browse... and select the .bat file you saved in Step 4.
15. Click Open, then click OK to save the new Startup Script.
16. Click OK to close the Startup Properties screen.
17. Close the Group Policy Management Editor.
18. Under the Group Policy Management screen, right-click your new GPO and ensure there is a checkmark next to "Link Enabled". Your GPO should now be active.

As long as the GPO is active, the batch file is run each time a computer, that is subject to the GPO, starts.

To test that the installation was successful: Open the mail client on a client machine within your domain. Click on a link within an email and make sure you're receiving Second Chance prompts. If you're not, check out our Troubleshooting tips at the bottom of the page.

User Experience

Once Second Chance is installed and the service is running, your users will see a prompt the first time they click on a URL that you have not added to the “No Prompt” domain list.

Here is an example of that prompt:

The prompts will vary depending on the link they're clicking on. If it is a Punycode link, the user prompt will look slightly different. You can update the content of the prompt messages in your Second Chance Settings.

 

What happens if my user continues or aborts their action?

If they choose to abort their action, the prompt will be closed, and the URL will not be opened. If they choose to continue, their browser will navigate to the URL they clicked on. Either action taken will be recorded in the data and reports on your console.

Troubleshooting

If you’ve installed through Group Policy and you are not seeing Second Chance prompts, follow the below steps on the client machine where it should be been installed:

1. Check your Add/Remove Programs list for "Second Chance". If you don't see it, attempt to follow the Command Prompt instructions shown below. If you do see Second Chance in your list of Programs, move on to the next step.
2. Open the Services application, services. msc, and check to see if the following services are running. If not, you can restart the computer or start or restart the services so that you can receive Second Chance prompts when you click on a link. 
   • knowbe4.secondchance.service
   • knowbe4.secondchance.opmanger
3. Command Prompt Instructions:
   • Open an elevated Command Prompt (cmd) (run as Admin) on the client device you’re attempting the install on and enter the following commands to troubleshoot:
     • gpupdate /force
       • This entry will force an update of Group Policy on the client machine you are logged in to.
     • gpresult /r
       • This entry will let you review whether or not the Group Policy you set up is being applied to the client machine you are logged in to.
4. Make sure you are using a UNC file path with your GPO installation (Example: \\Server\Volume\File).
5. Restart the machine you're trying to install Second Chance on.
6. If installing using a .bat file, it needs to be run with sufficient privileges.
