Collabfiltrator

Summary: Collabfiltrator is a Burp Suite extension, version 4.0.1, that assists in exfiltrating blind Remote Code Execution and SQL injection output over DNS via Burp Collaborator. It was authored by Adam Logue, Frank Scarpella, Jared McLaren and Ryan Griffin, last updated 31 January 2025, and is distributed through the BApp Store with an estimated overall system impact rated Low.

Bottom line: This is a tool that turns blind RCE and SQL injection into readable output by tunneling it out over DNS through Burp Collaborator, a channel most network defenses treat as routine. PortSwigger states the extension is written by third-party users and carries no warranty, so anyone installing it is trusting code it did not review.
