AWS Signer
Summary: PortSwigger lists a Burp Suite extension, Burp Extension for AWS SigV4 Signing, version 2.1.0, last updated 29 January 2025, that lets a user create a profile specifying which credentials sign requests. The extension checks each request passing through Burp and, if it carries both the "X-Amz-Date" and "Authorization" headers, re-signs it with the profile's credentials and updates the headers.
Why it matters: The extension rewrites AWS SigV4 signing on any request that already carries an X-Amz-Date and Authorization header, so a tester's profile credentials replace whatever identity the request was signed with. PortSwigger states the extension is written by third-party users and makes no warranty about its quality or usefulness.
