SQLMap DNS Collaborator

Summary: PortSwigger's BApp Store lists SqlmapDnsCollaborator, a Burp Suite extension by Luca Capacci, version 1.0, that enables DNS exfiltration with Sqlmap with zero configuration, requiring no domain name or public IP, only a computer running Sqlmap and Burp. The listing was last updated 24 March 2021 and rates overall system impact as Low, with PortSwigger noting that extensions are written by third-party users and come with no warranty of quality or usefulness.

What you should know: DNS exfiltration is a channel most outbound controls watch far less closely than HTTP, and this extension removes the two setup barriers - a domain and a public IP - that previously limited who could run it, so a tester or attacker with Sqlmap and Burp needs nothing else.
