On the night of October 6, 2025, the internet experienced a seismic event: a massive Distributed Denial of Service (DDoS) attack disrupted major platforms including Steam, PlayStation Network, Riot Games, Hulu, Epic Games, and even infrastructure providers like AWS and Cloudflare. The suspected source? The Aisuru botnet, which unleashed a staggering 29.69 terabits per second of traffic – the largest DDoS attack ever recorded. Multiple news sites reported.
What Happened?
- Targeted Platforms: Gaming services (Steam, Riot Games, PlayStation Network), streaming platforms (Hulu), and cloud infrastructure (AWS, Cloudflare).
- Type of attack: Sophisticated TCP Carpet Bombing techniques that mimic legitimate traffic.
- Effects: Millions of users worldwide lost the connection to their services. Ranked games were deactivated, streaming services were unavailable and even major cloud providers began to falter.
What companies need to learn from this
1. DDoS protection is not a luxury
Even if your company is not the size of Steam or AWS, DDoS attacks are increasingly affecting SMEs. Protection mechanisms such as traffic filters, rate limiting and cloud-based defense solutions are indispensable today.
2. planning resilient infrastructure
Attackers are using increasingly sophisticated methods. Companies need to design their systems in such a way that they remain stable even under high loads – for example through load balancing, redundant systems and emergency plans.
3. monitoring and early warning systems
AI-supported systems can detect unusual traffic at an early stage and react automatically. Investing here saves valuable time in an emergency.
4. awareness and responsiveness
Technology alone is not enough. Employees also need to know how to react in the event of an attack – for example, through clear communication channels and defined escalation processes.
Conclusion: the threat is real – and it is growing
The attack on October 6, 2025 shows: The dimensions of modern cyber attacks go beyond all previous ideas. Companies must act now – preventively, strategically and holistically.
