Checks any email against databases of known internet leaks or data breaches, to check if your email may have been exposed, as other sensitive personal information: Have I Been Pwned (HIBP) functions as a centralized repository for data breach aggregation, indexing over 14 billion unique records sourced from public leaks and malware-driven stealer logs. The platform enables users to query email addresses and phone numbers against known compromises to identify specific data classes exposed, such as passwords, physical addresses, or IP histories. For organizational security, it provides a RESTful API for automated credential checking and a domain search feature that allows administrators to monitor entire corporate namespaces for systemic exposure without requiring the storage of plain-text passwords.
HIBP could be applied to secure the digital supply chain and protect proprietary intellectual property. Professionals in these sectors could utilize such service to:
- Integrate the Pwned Passwords API into authentication systems for Industrial Control Systems (ICS) to block the use of known compromised credentials.
- Audit engineering and research teams’ corporate identities to mitigate the risk of corporate espionage and the theft of sensitive R&D data or proprietary designs.
- Monitor innovation hubs for credential leaks that could facilitate lateral movement within a corporate network or unauthorized access to simulation environments.
- Maintain quality assurance standards by ensuring that third-party vendors and contractors adhere to strict credential hygiene, thereby reducing the risk of ransomware-induced production interruptions.
