By exploiting HPACK compression amplification and HTTP\u002F2 flow-control mechanisms, attackers can force servers to consume massive amounts of memory (32GB) within seconds using only a 100 Mbps connection. This affects major web servers including Apache, NGINX, IIS, Envoy, and Cloudflare Pingora, highlighting the critical importance of timely patching and proactive vulnerability management. The attack's effectiveness against multiple platforms underscores how protocol-level flaws can have widespread impact across the internet infrastructure.","**Immediate actions:**\n- Apply available patches for NGINX (1.29.8) and Apache httpd (CVE-2026-49975) immediately\n- Implement rate limiting and connection throttling at load balancers and firewalls\n- Monitor server memory usage and configure alerts for abnormal consumption patterns\n\n**Long-term improvements:**\n- Establish automated vulnerability scanning for all internet-facing web servers and proxies\n- Implement DDoS protection services with HTTP\u002F2 attack mitigation capabilities\n- Maintain an inventory of all HTTP\u002F2-capable infrastructure components for rapid patch deployment\n\n**Detection measures:**\n- Deploy network monitoring to detect suspicious HTTP\u002F2 traffic patterns and connection anomalies\n- Configure memory and performance baselines to identify potential DoS attacks in progress",[12,13,14,15,16],"CIS Control 7","NIST SP 800-40","CIS Control 12","NIST SP 800-61","CIS Control 1","published","2026-06-03T20:06:19.917337+00:00","2026-06-03T20:06:19.578+00:00",{"id":7,"url":21,"slug":22,"title":23},"https:\u002F\u002Fwww.bleepingcomputer.com\u002Fnews\u002Fsecurity\u002Fnew-http-2-bomb-dos-attack-crashes-web-servers-in-under-a-minute\u002F","new-http-2-bomb-dos-attack-crashes-web-servers-in-under-a-minute-f1e95b","New 'HTTP\u002F2 Bomb' DoS attack crashes web servers in under a minute",[25,31],{"id":26,"name":27,"slug":28,"description":29,"color":30},"05757c8d-6b93-4194-b35d-7359e7d33b0e","Vulnerability Management","vulnerability-management","Missing scans, no risk prioritization","#fb923c",{"id":32,"name":33,"slug":34,"description":35,"color":36},"af7fce9e-1ce8-4156-93bc-09dcfbfdf29d","Patch Management","patch-management","Unpatched vulnerabilities, delayed updates","#ef4444",[38],{"id":39,"date":40,"edition":41,"title":42,"audio_url":43},"eb19cb0d-d183-4ad0-b85a-52a15ebfb4ba","2026-06-04","morning","ThreatNoir Morning Brief — June 4","https:\u002F\u002Fcdn.threatnoir.com\u002Fpodcasts\u002F2026-06-04\u002Fthreatnoir-morning-brief-2026-06-04.mp3"]
