pwnedOrNot
Check breached emails and find exposed passwords from public dumps
...The tool works by interacting with the HaveIBeenPwned (HIBP) API to determine if a given email address appears in breach databases. If the email is found in a breach, the tool proceeds to search for associated passwords within publicly available data dumps. This two-phase approach allows investigators, security professionals, and researchers to assess the exposure level of compromised accounts using publicly accessible breach information. The tool displays useful breach details such as the name of the breach, the affected domain, the breach date, and several status indicators related to the authenticity and status of the breach. pwnedOrNot can also analyze domains to determine whether they have been involved in breaches and can list all breached domains available through the HIBP database.
