The allintext:username operator ensures that the word "username" appears somewhere in the file’s content. In log files, this typically appears in formats like:

[2024-03-15 08:23:46] DEBUG: Password field received: P@ssw0rd123

If the log also contains the word "passwordlog" (perhaps as a filename or header), and "facebook" (indicating the OAuth endpoint), the dork will surface that exact file.

If you discovered that your domain appears in such a dork, or you want to prevent this exposure, follow these steps:

This is the wildcard. In context, "fixed" likely refers to patched vulnerabilities, corrected log configurations, or archived bug reports. It may also indicate the searcher is looking for a "fixed" version of a previous exploit, or for pages discussing how a passwordlog issue was resolved.

The combined intent: Find publicly indexed .log files that contain usernames and passwords (specifically for Facebook) where the issue might reportedly be "fixed," but the log remnants remain online.

The most intriguing part of the keyword is fixed. Why would a security researcher include "fixed" when hunting for live passwords?

Three theories:

Identify unintentionally exposed Facebook usernames/emails and passwords in publicly indexed .log, .txt, .csv, or backup files.
