Update May 13: In an effort to enhance user experience and highlight the most timely and actionable information for cyber defenders, CISA announced a shift in how we share cybersecurity alerts and advisories. We recognize this has caused some confusion in the cyber community. As such, we have paused immediate changes while we re-assess the best approach to sharing with our stakeholders.   Starting May 12, CISA is changing how we announce cybersecurity updates and the release of new guidance. These announcements will only be shared through CISA social media platforms and email and will no longer be listed on our Cybersecurity Alerts & Advisories webpage.   The focus of our Cybersecurity Alerts & Advisories webpage will now be on urgent information tied to emerging threats or major cyber activity. CISA wants this critical information to get the attention it deserves and ensure it is easier to find. We’ll continue to communicate releases and updates to our stakeholders. To stay informed, subscribe to receive our email notifications on CISA.gov. You can also follow us on X @CISACyber for timely cybersecurity updates.  Note: If you’ve previously used RSS feeds to track Known Exploited Vulnerabilities Catalog updates, please subscribe to the KEV subscription topic through GovDelivery to continue receiving notifications.    We greatly appreciate stakeholder feedback which played a part in this change and thank you for staying connected with CISA.
