Have I Been Pwned has added the US automotive marketplace Edmunds to its breach corpus with 177,860 unique email addresses. Edmunds is a widely used car-research and shopping platform offering pricing, reviews, and dealer listings. As is typical for HIBP additions, the underlying breach source and disclosure details are not published alongside the entry, but the listing lets individuals and organizations check whether their accounts appear in the leaked dataset. Affected users should anticipate car-buying-themed phishing such as financing offers, dealer-contact lures, or vehicle-quote follow-ups, and should rotate any reused passwords. The addition continues a steady run of mid-size US consumer-platform breaches surfacing in HIBP.
