# synflood

SYN flood denial-of-service (DoS) attack coded in C using raw sockets. Generates random spoofed IPs at each new packet.

## Build

`make clean` 


`make`

## Usage

`sudo ./synflood    `

## Example

`sudo ./synflood 1.2.3.4 OWNED 10 80`

Will create 10 threads which will send the following TCP/IP packet in loop:

```
