1) Q: How is my information protected on the PhishER platform?

A: PhishER uses all of KnowBe4's security and privacy best practices, as detailed on our Security page. For an added layer of protection, you can enable multi-factor authentication on your admin account in the KnowBe4 console.

2) Q: Do I need to use the PAB to forward emails to my PhishER inbox?

A: As an alternative to using the PAB, you can manually forward all user-reported emails to a PhishER-generated email address tied to your organization's PhishER platform.

With this method, you can download the .eml file, attach the .eml file to an email, and send it to PhishER. PhishER will recognize this process as a PAB report.

Keep in mind, this method of email forwarding requires that forwarded emails are transmitted in a .eml format (RFC 822), which includes the complete headers and email body from the original email.

Visit the PhishER Settings article for more information on how to set this up.

3) Q: How do I provide PhishER access to users?

A: To provide access to a user to manage PhishER, you must Enable PhishER access in their KnowBe4 Security Awareness Training platform User Profile. Security Awareness Training platform admins will automatically have access to PhishER.

4) Q: Where do I find my Saved Rooms?

7) Q: Is there a limit to how many Reporting Emails I can generate?

A: No. You can generate as many reporting email addresses as you would like.

13) Q: How quickly can we get our PhishER platform set up?

A: Setup time will vary based on your environment. If you're using KnowBe4's free Phish Alert Button in your organization, you can get started with PhishER in just a few clicks. PhishER offers System Rules to get you started with dispositioning emails fast. However, you'll want to spend some time customizing rules, tags, and actions to help you process and respond to reported emails faster.

14) Q: Can I use PhishER to process and block viruses?

A: No, PhishER was not designed to be a mail filter. The purpose of PhishER is to provide your organization with a platform to evaluate all suspicious emails reported by your users. However, you can use PhishER to detect commonalities in the reported emails to automate your incident response actions.

15) Q: Can I open up attachments in PhishER safely?

A: KnowBe4 does not advise that you open up attachments in PhishER, even if VirusTotal marks them as safe. Any attachments that you want to analyze can be opened in a safe, secure sandbox.

16) Q: Is the data sent to and from my PhishER platform encrypted?

A: Yes, PhishER utilizes TLS protocol for communication in and out of the platform.

17) Q: How is PhishER access managed?

A: An account admin can enable or disable PhishER access for any admin or user from the individual's User Profile settings in the KnowBe4 console.

 

18) Q: Can I inform an end-user when a message is tagged as SPAM?

A: In PhishER, you can alert an end-user when a message is tagged as SPAM by creating an Action that includes the following settings for steps 1, 2, and 3 on the Action Details screen:

1. For Choose how this action should be triggered, select the Specify Tags option. Then, select HAS ANY and add all of your spam-related PhishER tags.
2. (Optional) For Choose the action to be taken on matched messages, we recommend that you select the Set Status, Set Priority, and Set Category actions. For the Set Status action, select Resolved from the drop-down menu. For the Set Priority action, select Low from the drop-down menu. For the Set Category action, select Spam from the drop-down menu.
3. For Choose how you would like to report this action, select the Send Email option. When this option is selected, you can create a custom email response that will automatically send to the recipients (end-users) of your choice when a message is tagged as SPAM. Visit our How to Create a Custom Email Template in PhishER article for more information.

 

19) Q: What are some recommendations for PhishML thresholds?

A: Here are some recommended settings when it comes to using the PhishML thresholds:

• A lower confidence threshold value (80-90) will lead to an increase in the number of messages that are automatically tagged by PhishML as being clean, spam, or a threat. We suggest setting a lower confidence threshold for PhishML to identify messages that are spam. This will allow PhishER admins to quickly resolve or eliminate non-threatening messages.
• A higher confidence threshold value (95-99) will lead to a decrease in the number of messages that are tagged by PhishML as being clean, spam, or a threat. We suggest setting a higher confidence threshold for PhishML to identify messages that are either clean or a threat. This will allow PhishER admins to prioritize messages that need further analysis or review before taking an action.

 

20) Q: What security levels are required to enable PhishRIP with Google Workspace (formerly G Suite)?

A: In order to enable PhishRIP with Google Workspace, you must have a Google Workspace Account Admin email address.

 

21) Q: What can I do when I integrate PhishER with my KnowBe4 Security Awareness Console?

A: The integration between PhishER and the KnowBe4 Security Awareness Console provides you with a better understanding of how your users interact with real phishing emails. With certain Actions being reported to your Security Awareness Console, you can create a Smart Group that targets specific users based on how they treated real phishing emails. For example, you can create a smart group that searches for users that did not report threats and then use this information to create a targeted training campaign and to reiterate the importance of using the Phish Alert Button.

 

22) Q: What permissions do I need to connect my Microsoft 365 instance to PhishRIP?

A: In order to grant PhishRIP access to all of the mailboxes in your Microsoft 365 instance, you must have a Microsoft 365 Admin account with global permissions enabled. This account can then accept the permissions needed to connect to Microsoft 365. The account information used to sign in to Microsoft 365 will not be stored in PhishER. This email address can also be removed by another Microsoft 365 admin. You can find the required permissions in our PhishER Settings article.

 

23) Q: What version of YARA does the PhishER platform support?

A: The PhishER platform currently supports YARA version 3.11.0.

 

24) Q: What security measures are in place to ensure that information is not lost or stolen when using PhishRIP?

A: PhishRIP uses the information entered into the Customized Criteria feature to pull any emails that are similar to any potentially threatening emails that have been sent to PhishER through the Phish Alert Button.

You can also limit the access of the users that you add to the PhishER platform by using the new Security Roles feature. With Security Roles, you can grant Limited or Full access to the following console areas:

• Rooms
• Inbox
• Rules
• Actions
• PhishRIP
• Settings

Using security roles, you can specify which admins have the access to be able to initiate PhishRIP queries.

Finally, if there is ever anything quarantined and later you discover that message to be clean, you can easily restore the message from inside PhishER.

 

25) Q: What format of the PEM TLS certification is required for the PhishER TLS connection settings for Syslog?

A: The format of the PEM TLS certification should include the header, a new line, the certificate information, a new line, and the footer. Below is an example of the accepted format:

26) Q: When a PhishFlip campaign is started, is the tracking duration always set to 3 days? Is there any way to modify it?

A: Yes. By default, all PhishFlip campaigns are set to have a tracking duration of 3 days. Currently, this setting cannot be modified.

 

27) Q: Will PhishFlip work with attachments found in reported emails?

A: Yes. PhishFlip will convert the attachment into an HTML template.

 

28) Q: How can I use attachment prefixes to find emails with similar attachments?

• random
• ran
• rando
