Leaked Checker API offers a powerful solution for developers and businesses to detect if an email address has been compromised in data breaches. By incorporating this service into apps and websites, it’s possible to perform pre-checks before allowing user logins or new signups, reducing the risk of unauthorized access and digital impersonation.
Leaked Checker API
Leaked Checker monitors a wide collection of dark web data breaches and provides a simple RESTful service for searching breached passwords via an account (Email or alphanumeric username). The response is returned in JSON with a number of details including the status of the search, a list of all of the breaches that the hash has been observed in and a “count” that is based on how many times the hash was observed in any of the retrieved breached databases. The search result is also padded such that attackers intercepting the response can’t determine which hash prefix was searched for, protecting users’ privacy and security.
Hackers and bad actors are exploiting the fact that leaked passwords can be used in a variety of attacks. The Verizon 2021 Data Breach Investigations Report found that 61% of data breaches involved credential information (i.e., passwords). As such, it’s critical to ensure that any passwords used by employees or customers aren’t exposed on the dark web.
