Troy Hunt's "Have I Been Pwned" (HIBP) has received a significant update, moving from a static database of breached accounts to a real-time API-based system. This "HIBP 2.0" allows subscribers to receive notifications the moment their data appears in a new breach, offering proactive protection against identity theft and fraud. The change also brings new features like domain search, allowing organizations to monitor employee accounts for breaches. While the free public search for individual accounts remains, the enhanced features are available through a paid subscription, supporting the continued operation and development of this valuable security service. This shift allows HIBP to handle larger and more frequent data breaches while offering users immediate awareness of compromised credentials.
Troy Hunt, the creator and maintainer of the popular data breach notification service "Have I Been Pwned" (HIBP), has announced a significant overhaul of the platform, dubbing it "HIBP 2.0." This update introduces several major improvements focusing on enhanced user experience, improved data handling, and greater accessibility.
One of the most significant changes is the shift to a new search engine built on k-anonymity. This innovative approach allows users to search for their email addresses without directly exposing the address to the HIBP server. Instead, the first five characters of the hashed email address are sent to the server, which returns all matching hashes. The final verification of a breach is then performed client-side within the user's browser, significantly enhancing privacy and security. This eliminates the previous requirement for the entire hashed email address to be sent to the server, reducing the risk of potential exposure.
The revamped website also boasts a redesigned user interface with a more modern and streamlined aesthetic. This includes improved navigation and a more intuitive presentation of breach information. Beyond aesthetics, the update emphasizes accessibility, ensuring the platform is usable for a wider audience, including those with disabilities.
In addition to the front-end changes, HIBP 2.0 incorporates substantial back-end improvements. The entire codebase has been rewritten using .NET 6, leveraging the latest advancements in the framework for improved performance, stability, and maintainability. This modernization lays the groundwork for future enhancements and ensures the long-term viability of the service.
Furthermore, Hunt addresses the issue of data storage, highlighting the ever-growing challenge of managing the massive volume of breach data. He discusses the complexities of data retention, particularly concerning older breaches and the potential for future inclusion of additional datasets. While acknowledging the increasing costs associated with storage, Hunt reaffirms his commitment to keeping HIBP free for individual users, emphasizing the importance of providing this crucial service without cost as a public good. The updated architecture is designed to better handle this growing data volume while also optimizing search performance.
Overall, HIBP 2.0 represents a significant leap forward in the evolution of the service, combining enhanced privacy features with a modernized platform and a continued commitment to free accessibility for all users. The k-anonymity implementation, coupled with the backend rewrite and UI/UX improvements, positions HIBP to continue its vital role in empowering individuals to take control of their online security.
