Backslash Powered Scanner

Summary: PortSwigger lists Backslash Powered Scanner, a Burp Suite extension by James Kettle at version 1.30, as a complement to Burp's active scanner that uses a novel approach to find and confirm both known and unknown classes of server-side injection vulnerabilities. The listing says the approach, evolved from classic manual techniques, brings casual WAF evasion, a tiny network footprint, and flexibility against input filtering, with a whitepaper at PortSwigger's blog and a last update of 30 April 2025.

Key Takeaway: The extension targets unknown classes of server-side injection, not just known signatures, and its stated WAF evasion and small network footprint mean traffic from it may not look like a scan to your defenses. PortSwigger also states that extensions are written by third-party users of Burp and come with no warranty of quality or usefulness.
