Credential leakage occurs when usernames, email addresses, and passwords are exposed through data breaches, infostealer malware, or publicly shared datasets.

Once exposed, credentials are often reused in automated attacks such as account takeover or credential stuffing.

Many organisations are affected without being aware of it.
