If you found this file on your own computer or within a browser's data folder, it is likely not a security breach but a legitimate tool:
Attackers can immediately use the passwords to log into websites, databases, or FTP servers, bypassing the need for complex hacking techniques [1]. Ensure autoindex is set to off in your configuration
(advanced search) to find sensitive files that have been accidentally left public on web servers. What the Search Query Means "Index of"
If a site administrator accidentally leaves a file named password.txt , credentials.txt , or similar in a public-facing folder, that file becomes accessible to anyone with a browser. The Role of Google Dorking (advanced search) to find sensitive files that have
Beyond search engines, automated botnets continuously scan the global IPv4 address space. These bots send HTTP requests to common paths (like /backup/ , /config/ , or /database/ ) looking for open directories and standard file names. Once found, the contents are scraped automatically and aggregated into credential stuffing lists. The Risks of Plaintext Credential Exposure
