PuppyFinder.com

In early 2017 the online puppy marketplace PuppyFinder suffered a significant data breach. The incident resulted in the unauthorized exposure of a database containing sensitive user information. Security researchers discovered that the leaked data included personal details of thousands of users who were looking to buy or sell pets on the platform. The breach was primarily attributed to a vulnerability that allowed attackers to gain access to the backend storage where member information was kept. This incident highlighted risks for niche classifieds websites and the importance of securing personal data against credential stuffing and other common attack vectors.
