Credential Leak Detection (Breach Database Exposure)

high
CWE-521Data Protection

What is Credential Leaks?

Employee and customer email addresses associated with your domain may appear in public data breaches. Attackers use these leaked credentials for credential stuffing attacks against your login endpoints.

How it works

Attackers download breach databases from dark web marketplaces and forums. They extract email-password pairs matching your domain and attempt them against your login pages, password reset flows, and API endpoints. Because most people reuse passwords, a breach at an unrelated service often grants access to your systems.

Impact

Account takeover, unauthorised access to internal systems, lateral movement through the organisation, data exfiltration, and business email compromise. A single leaked admin credential can provide full system access.

How ShieldReport detects this

ShieldReport cross-references email addresses associated with your domain against the HaveIBeenPwned breach database and flags any matches with the specific breach source, date, and exposed data types.

How to fix it

Force password resets for all affected accounts. Enforce multi-factor authentication across the organisation. Implement breach-aware password policies that reject known-compromised passwords. Monitor for new breaches continuously.
