Spoof Proof - Domain Spoofing Validation

Summary: PortSwigger's BApp Store lists SpoofProof, a Burp Suite extension by Chetanya Sharma (AggressiveUser), version 1.0.3, last updated 24 February 2025, designed to verify email domain spoofing vulnerabilities and validate DNS-based email security configurations including DMARC, SPF, and DKIM. PortSwigger states the extension is written by a third party and makes no warranty about its quality or usefulness for any particular purpose.

Bottom line: Domain spoofing validation lands in the hands of whoever installs a third-party extension into Burp, and PortSwigger explicitly disclaims any warranty on quality or fitness - so the DMARC, SPF, and DKIM results your team acts on carry no vendor assurance behind them.
