MCProof
Every public website gets probed by automated bots looking for password files, old plugins and login pages to guess at. Your server writes all of it down in its access log, and almost nobody reads it. Upload yours and we'll show you every attempt: who tried, what they went after, and whether anything got through.
/var/log/nginx/access.log or /var/log/apache2/access.log.A "got a success response" result means your server answered 200 to an attack request. It is a lead to check, not proof of a breach, because many sites answer 200 to every address. Automated analysis, not a forensic investigation.
