Coordinated port scan from APAC IP blocks (142.x.x.x) targeting SSH (22), HTTP (80), HTTPS (443). Attack pattern matches known botnet signature BH-2847. Automated blocking triggered at 02:17:31 (+8s). Zero successful intrusions. Threat neutralized.
Attack Duration
14 seconds
Action: Firewall rules updated. IP blocks added to global blacklist. Monitoring window extended +6h.
Sudden spike in connection requests (+2,847 req/s) caused brief latency increase (41ms → 67ms p50). Load balancer auto-scaled +2 instances at 02:17:29. Peak resource utilization: 78% CPU, 64% memory. System stabilized within 22 seconds. No customer-facing impact.
Latency Impact
+26ms peak
Action: Auto-scaling threshold lowered from 80% to 70% CPU to pre-empt future spikes. Cost impact minimal.
Attack triggered auto-scaling, adding $0.18/hour ($4.32/day if sustained). However, early detection saved estimated $127/day in potential downtime costs. Auto-scaling response was cost-efficient: 2 instances for 22 seconds = $0.001 total. ROI: 127,000%.
Potential Savings
$2.40/day
Action: Recommend pre-warming 1 instance during 00:00-06:00 CST (APAC prime time). Cost: +$1.20/day. Benefit: -15ms avg latency, faster attack response.
This attack matches pattern BH-2847 (botnet herder operating since 2024-11). APAC scan frequency: every 6-8 hours. Next attack predicted at 08:00-10:00 CST (92% confidence). Attack surface: SSH brute-force → web service enumeration → API discovery. Motive: credential harvesting for proxy network.
Attack Frequency

Next Attack ETA
08:00-10:00 CST
Action: Recommend SSH rate limiting during 08:00-10:00 CST window. Monitor for pattern evolution.
