mmquant | Last updated: Feb 15, 2022 01:29PM UTC

I can't dig the TXT record from the Burp Collaborator server. dig returns empty answer section $ dig txt dobc.mmquant.net @165.22.xx.xx ... ;dobc.mmquant.net. IN TXT I can see the DNS requests in the Burp Collaborator server log 2022-02-15 13:22:10.725 : Received DNS query with type TXT from [89.177.xx.xx] for [dobc.mmquant.net] containing no interaction IDs. DNS A record for the dobc.mmquant.net subdomain gets returned correctly $ dig a dobc.mmquant.net @165.22.xx.xx +short 165.22.xx.xx This is my config file # cat collaborator.config.json { ... "dns" : { "ports" : 53 }, ... "customDnsRecords": [ { "label": "_acme-challenge", "record": "275fe5b909adb10e41c78066e9485f7d", "type": "CNAME", "ttl": 60 } ] } Burp version 2022.1.1

Both types - CNAME/TXT - don't work.
