1. 개요[편집]

특정 서버나 네트워크에 과도한 트래픽을 발생시켜 정상적인 서비스 제공을 방해하는 사이버 공격.

원리는 requests로 서버에 과부화를 주는 것. ~~사실상 이코드로 DDos 공격은 불가능이다. 애초에 구글 도메인에 get을 해야하기에...~~

신기하게 깃허브에는 DDOS 코드가 존재한다...

2. 예시 코드[편집]

이게 디도스가 맞나... 싶을 정도로 그냥 트래픽만 늘리는... post를 get으로 바꾸어야 정상적을 받을 수 있다.
그냥 API 보내고 받을때 쓰는 아주 기초적인 코드다.

python

import requests

url = "https://www.google.com"

for i in range(1):
     a = requests.post(url)

print(a)
print(a.text)

        {
            HttpResponseMessage response = await client.PostAsync(url, null);

            Console.WriteLine(response);
            string text = await response.Content.ReadAsStringAsync();
            Console.WriteLine(text);
        }
    }

    return totalSize;
}

        curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);

        
        res = curl_easy_perform(curl);

        
        std::cout << "Response Code: " << res << std::endl;
        std::cout << "Response Text:\n" << response << std::endl;

사이버 공격은 엄연한 범죄이다.
