Why now
  • Multiple critical vulnerabilities exploited within days of disclosure.
  • Oracle flaw exploited before public exploit code surfaced, showing advanced attacker capabilities.
  • Citrix and Cisco vulnerabilities also targeted immediately after PoC release.
Why it matters
  • Exploitation shortly after disclosure increases risk to unpatched systems.
  • Early attacks before public exploit code indicate sophisticated threat actors.
  • Highlights the critical need for rapid patch deployment and monitoring.
