| Hackers used hundreds of thousands of internet-connected devices that had previously been infected with a malicious code – known as a “botnet” or, jokingly, a “zombie army” – to force an especially potent distributed denial of service (DDoS) attack. | Hackers used hundreds of thousands of internet-connected devices that had previously been infected with a malicious code – known as a “botnet” or, jokingly, a “zombie army” – to force an especially potent distributed denial of service (DDoS) attack. |
| The aim of a DDoS attack is to overwhelm an online service with traffic from multiple sources, rendering it unavailable. Dyn said attacks were coming from millions of internet addresses, making it one of the largest attacks ever seen. | The aim of a DDoS attack is to overwhelm an online service with traffic from multiple sources, rendering it unavailable.
