ALL-TIME RECORD INCIDENT REPORT · OCTOBER 18, 2026
All-Time Record L7 DDoS: 9.4+ Billion Requests.
Official technical incident report on deflecting a coordinated dual-wave distributed HTTP/2 TLS 1.3 assault generated by Reborn C2 | illegal service. The assault delivered over 9.4 Billion total requests across two massive waves (6.0B initial barrage + 4.39B follow-up barrage) with peak burst spikes surging to 10.0M req/s and sustained pressure between 500k–900k req/s. Through inline Nginx in-memory PoW fast-path validation, 16-core CPU affinity, and kernel netfilter /24 blackholing, the platform held 100% operational availability with 4.4 ms origin response latency.

Wave 1: Initial 6.0B Flood & TLS 1.3 Key Share Poisoning
Massive flood delivering ~6.0 Billion requests. Attackers deployed corrupt TLS 1.3 Key-Share extensions and HTTP/2 stream multiplexing, attempting to choke local verification queues.

Live Engineering: Nginx In-Memory Fast-Path Deployment
Security team hot-patched Nginx edge: implemented inline in-memory PoW fast-path checking ($mit_pow_need), pinned 16 worker processes across all 16 physical CPU cores, and tightened /24 subnet concurrency.
21:30:22 UTC
Wave 2: Reborn C2 Maximum Assault (4.39B Requests)
Reborn C2 launched follow-up barrage targeting /record/ with 24.0M req/s capacity. Attack ramped from 33.5k to 433k+ continuous RPS in under 10 seconds.
21:30:32 UTC
All-Time Peak Record (866.8k RPS · 10.0M/s Burst Spike)
All-time record peak: 866,787 requests ingested in 2 seconds (sustained 500k–900k req/s). In-memory fast-path rejected 99.8% of hostile connections via HTTP 444 in zero CPU cycles without touching backend workers.
21:34:00 UTC
Hardware Wire Drops & Subnet Blackholing
Attacking /24 subnets blackholed in Netfilter; 1,933,867 raw packets dropped on wire; 5,539,388 malicious HTTP/2 sessions discarded at edge proxy.
21:38:00 UTC
Full Recovery: Dual-Wave Assault Defeated
Reborn C2 fleet exhausted. 9.4+ Billion total requests successfully mitigated. Origin latency steady at 4.4 ms, CPU load dropped to 0.84, zero origin degradation.
