API Recon

  1. Check for documentation

    • Swagger -> /openapi.json

    • GraphQL -> https://graphql.org/learn/introspection/ -> https://github.com/prisma-labs/get-graphql-schema

    • manual -> site:target.tld intitle:api | developer

  2. Search for APIs

    • site:target.tld inurl:api

    • intitle:"index of" "api.yaml" site:target.tld

    • intitle:"index of" intext:"apikey.txt" site:target.tld

    • allintext:"API_SECRET*" ext:env | ext:yml site:target.tld

  3. Enumerate endpoints / methods

    • https://wordlists-cdn.assetnote.io/data/automated/httparchive_apiroutes_2023_08_28.txt

    • swagger -> https://github.com/danielmiessler/SecLists/blob/master/Discovery/Web-Content/swagger.txt
