The infected code can provide your device’s access to the hacker remotely. And on the perfect attack time, Your smart devices get involved in the attacks.

How does a DDOS Attack is performed?

Generally, All the websites are hosted on servers with specific limits. These limits here include having 10,000 server requests per second. Which means that the resources of the server can allow 10,000 people to surf the site in a second.

So the hacker researches all the resources of the server and starts the attack. The hacker along the with the bot army together sends millions and trillions of requests per second on to the targeted site.

Thus the server or the CPU/GPU resources of the site cannot handle those requests and makes it impossible to surf for organic visitors or users. Within no time the server gets crashed.
