Credential exposure rarely starts inside your own infrastructure. Most cases originate from third-party breaches, password reuse, or historical leaks that resurface on forums and marketplaces. Timing matters: if you find out late, account takeover attempts are already underway.
Detection
The Data Exposure Scan flagged a recent post that contained credentials tied to a corporate domain. The finding was consolidated into an actionable report: affected emails, posting context and signals suggesting the credentials were plausible.
Response
After validating the alert, the team enforced password resets and session revocation across the affected accounts, and rolled out MFA where it was missing. Access logs were reviewed to rule out suspicious activity.
Key takeaways
- Credential exposure often comes from third parties: external visibility is critical.
- Reducing time from detection to reset limits takeover risk.
- Enforcing MFA and strong password policies reduces reuse impact.
