4. Scan beyond Firewalls and IDS

1. Various Firewall Evasion techniques with nmap

Fragmented scan

nmap -f 192.168.18.110

Use common source ports

nmap -g 80 192.168.18.110

It used a common port to send the traffic. So, it evades firewall.

Sending smaller packets to scan

nmap --mtu 8 192.168.18.110

it fragments the packets (maximum 8 bytes size)

Decoy scan

nmap -D RND:10 192.168.18.110

decoy hides the actual source IP in a number of random IP addresses to hide the actual identity.

Spoof mac

nmap -sT -Pn --spoof-mac 0 192.168.18.110

-sT TCP scan

-Pn do not perform host discovery

--spoof-mac randomize the mac address

2. Colasoft packet builder to avoid AV

windows

3. Custom packet in Hping3

hping3 --udp --rand-source --data 500 192.168.18.110

--data specifies the packet body size

hping3 -S -p 80 -c 5 192.168.18.110

-S is for syn scan

-p port number

-c number of packets

Flood/ DDOS with Hping3

hping3 192.168.18.110 --flood
