Avaliable Attacks (will add more soon)

TCP SYN Flood: A TCP SYN flood attack exploits the TCP handshake process. It sends a barrage of SYN requests to the target, overwhelming its ability to respond and establish legitimate connections.

ICMP Flood (Ping of Death): An ICMP flood attack sends a high volume of ICMP Echo Request (ping) packets to the target, aiming to overwhelm its network bandwidth and processing power.

UDP Flood: A UDP flood attack involves sending a large number of UDP packets to random ports on the target system, causing it to become overwhelmed as it processes the packets and replies with ICMP Destination Unreachable messages.

HTTP Flood: An HTTP flood attack aims to overload a server with HTTP requests, exhausting its resources and potentially leading to denial of service.

How it works:

  • Let's take UDP Flood as an example.

  • A UDP flood attack can be initiated by sending a large number of UDP packets to random ports on a remote host. As a result, the distant host will:

    • Check for the application listening at that port;
    • See that no application listens at that port;
    • Reply with an ICMP Destination Unreachable packet.

  • Thus, for a large number of UDP packets, the victimized system will be forced into sending many ICMP packets, eventually leading it to be unreachable by other clients. Net Strike can also spoof the IP address of the UDP packets, ensuring that the excessive ICMP return packets do not reach you, and anonymizing your network location.

  • However, unlike other types of attacks, HTTP Flood works in a somewhat different manner.

  • An HTTP flood attack aims to overload a server with HTTP requests. This type of attack can take various forms, such as GET or POST requests. As a result, the target server will:

    • Receive an overwhelming number of requests;
    • Attempt to process each request as a legitimate user;
    • Exhaust its resources (CPU, memory, bandwidth), potentially leading to slow responses or complete unavailability.

  • For a large number of HTTP requests, the server may become unresponsive or crash. Net Strike can generate high volumes of HTTP requests, emulating the behavior of multiple clients and stressing the target server.

Note

Including headers in the HTTP flood requests makes the requests appear more legitimate, as if they are coming from a real browser. This helps to avoid simple filtering mechanisms that may block requests without common headers. You can add more headers if you want.
