Burp Infiltrator without DNS lookup

Franz | Last updated: Apr 24, 2017 12:39PM UTC

Dear Portswigger Team, Thanks for the brilliant work on Burp Infiltrator. I frequently run Burp Collaborator in internal environments without any outbound Internet connectivity, which means I have to set up Burp Collaborator without DNS interaction support. As you mentioned in Burp Infiltrator's documentation, "The instrumentation hook performs a DNS lookup of the mutated Burp Collaborator domain.". As the DNS lookup will always fail in my set up, Burp Infiltrator will unfortunately fail to detect any invocation of unsafe functions with user-supplied input. Could you please add in a future version of Infiltrator the option to use HTTP(S) requests instead of DNS lookups as an initial check? This would be highly appreciated. Thanks and kind regards, Franz
