Found a rather interesting data breach search site which is an extension of Troy Hunts famous &#x27;Have I been pwned?&#x27; site. Pwned Tools - https:&#x2F;&#x2F;pwnedtools.com&#x2F;sandbox&#x2F; provides further insights into a user&#x27;s breached email address or addresses. It&#x27;s currently in Beta by looks of it but works quite well.
