For example:

If you stumble upon an exposed Excel file containing real credentials, the ethical response is:

You might think that this vulnerability is a relic of the 1990s. Unfortunately, it is still rampant. Here is why:

: If the spreadsheet contains customer credentials or personal identifiable information (PII), the exposure constitutes a data breach, triggering legal penalties under frameworks like GDPR, CCPA, or HIPAA. How to Prevent and Remediate Exposure

: Limits results strictly to Microsoft Excel spreadsheets (.xls or .xlsx). username password

Searching for filetype:xls username password on Google is – it is simply using a public search engine. However, what you do with the results determines legality:

: An administrator stores a backup file or an internal asset list in a public-facing directory on a corporate web server.

filetype:log "login failed" – Searches for server log files, which sometimes accidentally record the usernames and passwords typed by users.

Organizations should proactively audit their own exposure using the same techniques attackers use. You can safely check your domain by adding the site: operator to the search query.

Even if a spreadsheet leaks and an attacker gets a hold of a valid username and password, MFA acts as a critical safety net. If MFA is enabled across all corporate accounts, the stolen password alone will not be enough for the attacker to gain entry. Conclusion
