Intruder crashes Burp when using SOCKS5 proxy with DNS through proxy

Alex | Last updated: Jan 11, 2021 02:18AM UTC

Whenever I set Burp to go via a SOCKS5 proxy and I tick the box to send DNS requests through the proxy, everything works fine (proxy, repeater, etc) except Intruder, which shows an error "Failed to resolve hostname" and then the entire Burp freezes completely. I have to kill the process. This is on MacOS (both Catalina and Big Sur). I noticed that quite some time ago (sorry don't remember the Burp version it started happening on, think it was 2020.11.??). I'm now on 2020.12.1.
