What is DDoS?
Definition
A Distributed Denial of Service (DDoS) attack floods a website, application, or network with massive amounts of fake traffic from multiple sources, making it unavailable to legitimate users.
Think of it like this: thousands of people blocking a store entrance so real customers can't get in.
How It Works
Attackers use networks of compromised devices (called botnets) to simultaneously send requests to a target. The target's servers become overwhelmed and can't respond to legitimate traffic.
DDoS vs. DoS:
- DoS (Denial of Service): Attack from a single source
- DDoS: Attack from many sources simultaneously (much harder to stop)
A Brief History
- Early 2000s: First major DDoS attacks hit Yahoo, Amazon, eBay
- 2010s: Attacks grew exponentially with IoT device exploitation
- Today: Attacks regularly exceed 1 Tbps, targeting businesses of all sizes
Why Do Attackers Launch DDoS Attacks?
Financial Gain
- Ransom demands: "Pay or stay offline"
- In 2020, over 100 financial firms were targeted by Ransom DDoS campaigns
Competitive Sabotage
- Taking down competitors during critical business periods
- E-commerce attacks during sales events
Hacktivism
- Political or ideological protests
- Targeting organizations attackers disagree with
Diversion Tactic
- DDoS as a smokescreen while stealing data
- Part of Advanced Persistent Threat (APT) campaigns
- Security teams focus on DDoS while real breach happens elsewhere

This isn’t just protection—it’s proof. Customers can see the battle happening at the edge and know their service provider is actively keeping them safe.
