A dark web data leak occurs when stolen information from a breach is shared or sold on hidden online platforms. These leaks often include email credentials, financial records, internal documents, or full customer databases.

Unlike initial breaches, dark web leaks create long-term exposure. Once data enters underground markets, it can be resold repeatedly or released publicly to increase pressure on victims.

Monitoring and understanding these leaks is now a critical part of cybersecurity awareness.
