If you are a business owner, assume that an email.xls file exists somewhere on your network. Find it. Delete it. Secure it. If you are a curious student, look, but do not touch.

If you spend any time in the world of OSINT (Open Source Intelligence) or ethical hacking, you have likely encountered the term "Google Dorking." Among the thousands of specialized search strings (dorks), one stands out for its terrifying simplicity and effectiveness:
This dork specifically finds spreadsheets that are likely to contain columns of email addresses, names, and often passwords. You might be thinking: How can a spreadsheet be on Google if it isn't public?
