Hi You can find out more information on the Collaborator here: https://portswigger.net/burp/documentation/collaborator The payload is randomly generated and does not contain any identifiable information. If you received an issue including the DNS interaction, you should have some further information on the requests and responses that have triggered this.

If you have a found issue associated with the DNS vulnerability, you can use that to verify the vulnerability is present. In the documentation you linked previously (https://portswigger.net/burp/documentation/desktop/tools/collaborator-client), there are screenshots of the issue generated. This includes an advisory, the requests and responses that have triggered the vulnerability, and details on the DNS interaction. All of this information can be used to verify the findings of the Scanner. If you're looking for more information on the vulnerability, beyond what the advisory has told you, have you checked out our Web Security Academy? We have a lot of learning content for different vulnerabilities on there, including practical labs that can help you put in practice the things you have learned. You can find the Academy here: https://portswigger.net/web-security
