使用静脉进行 DoS 攻击

Question

我是静脉新手，我想使用泛洪技术进行 DoS 攻击。我曾尝试发送一条消息，用于在发生事故时使用，例如，由特定汽车发送一百万次。这足以进行 DoS 攻击吗？我可以让这段代码更复杂吗？

void TraCIDemo11p::handlePositionUpdate(cObject* obj) {
    BaseWaveApplLayer::handlePositionUpdate(obj);   
    if (externalID == "2"){ //2 is the attacker
       for (int i = 0; i<1000000; i++)
            sendMessage(mobility->getRoadId());
     }

注意：我使用的是 omnet 5.0、sumo-0.25.0 和 Venes-4.4、TraCIDemo11p.cc

Answer 2

您好，我使用 PingApp 进行了 DOS 攻击。我觉得你可以参考PingApp的源码。重要的部分是让 sendInterval 为 0.0001s。希望这会有所帮助！
