Utilities
Advisories, breach information, and places to check a worrying headline.
A short reference shelf, not a live threat feed. These links take you to other sites; nothing is embedded or queried in the background. The software directory’s open-source criteria apply to software recommendations, not to these government resources and reporting links.
Official advisories
- CISA cybersecurity advisories ↗
Technical advisories and recommended mitigations. Check the affected products and versions before deciding whether an advisory applies to you.
Official guidance, not a personalised assessment of your devices.
- CISA Known Exploited Vulnerabilities ↗
A catalogue of vulnerabilities with evidence of exploitation. Useful for deciding which applicable patches need attention first.
Absence from this catalogue does not mean a vulnerability is harmless.
Breach lookup
- Have I Been Pwned ↗
Check whether an email address appears in breach records held by the service. Optional notifications are handled by Have I Been Pwned.
Enter information only on the official site and review its privacy policy. A clean result is not proof an account has never been compromised.
Read its privacy policy ↗
Reporting
- BleepingComputer — data breaches ↗
Reporting on breaches and related incidents. Follow through to the affected organisation’s notice for its account-specific instructions.
An external news publication with its own advertising and privacy practices.
- Krebs on Security ↗
Security reporting and investigations by Brian Krebs, including fraud and breaches.
Reporting provides context; check dates and distinguish confirmed findings from ongoing investigations.
Resource descriptions checked October 27, 2026. These are links to public resources, not a security audit or endorsement of every claim they publish.
