Issue with Burp Collaborator

Mudit | Last updated: May 05, 2016 09:11AM UTC

Hi, We have a licensed version of Burp suite running and the license is issued to Cisco Systems India Pvt Ltd. We have been running Burp suite on our application and wanted to report an issue that we have been observing. Burp suite reported an issue "External Service Interaction(DNS)". Following response was reported as part of Collaborator response: "The Collaborator server received a DNS lookup of type A for the domain name bgvl6vznavuan2tr3ghrc2hosfy5myaqxhl6.burpcollaborator.net. The lookup was received from IP address x.x.x.x at 2016-May-05 07:10:44 UTC. " While Burp suite reported this, we have been trying to simulate a similar condition manually but could not. In packet capture, there were no outgoing traffic to the said collaborator input or any specified DNS address. Similarly while the Burp suite was running and the issue reported, the packet capture did not reveal any outgoing traffic for that domain specified in collaborator query. Is this an issue ? Please let us know.
