Cloudflare and Akamai have reported mitigating the largest DDoS attack in history, peaking at 29.7 Terabits per second (Tbps). The attack, launched by the “Aisuru” IoT botnet, specifically targeted European financial institutions using massive UDP floods.
Business Impact
This attack volume redefines the “worst-case scenario” for availability. Traditional on-premise DDoS appliances would be instantly overwhelmed. An attack of this magnitude can take down not just individual banks, but regional internet exchanges if not mitigated at the edge.
Why It Happened
The “Aisuru” botnet leverages millions of compromised consumer IoT devices (cameras, routers) connected to high-speed 5G and fiber networks, allowing it to generate unprecedented volumetric traffic.
Recommended Executive Action
Verify your organization’s DDoS resilience. Ensure critical customer-facing services are protected by a cloud-based scrubbing provider capable of absorbing multi-terabit attacks. Test your “failover” plans for a scenario where primary internet links are saturated.
