Threat Feed
The most recently confirmed actively-exploited vulnerabilities from CISA's Known Exploited Vulnerabilities (KEV) catalog — the highest-confidence "patch this first" signal available. No theoretical CVEs, no proof-of-concept exploits: every entry here has confirmed real-world exploitation.
How this stays current: This feed is fetched from CISA's official KEV catalog every time ByteTempest deploys an update to this site — not on every page load. We do this server-side during our build process rather than from your browser, because CISA's feed (like most government data feeds) doesn't permit direct cross-origin requests from arbitrary websites. The result is data that's accurate as of our last deploy, which in practice is frequent. For the canonical, real-time source, see CISA's KEV catalog directly →.
