Supported Protocols and Key Features

• Multiple Protocol Support : Inject handles Ethernet, ARP, IP, ICMP, TCP and UDP.
• Network Packet Injecting : Create and send custom network packets on specified network interfaces.
• Payload Integration: Load payload files into network packets.
• Network Sniffing : Capture network packets with customizable filtering options to focus on specific network protocols.

Installation

• Clone the repository from GitHub or GitLab:

git clone https://github.com/fksvs/inject
git clone https://gitlab.com/fksvs/inject

• Change directory to inject:

cd inject

• Build the project:

make

Usage Examples

Ethernet packet with the payload payload.txt to the MAC address 00:11:22:33:44:55 using wlp5s0 network interface:

inject eth -i wlp5s0 -K 00:11:22:33:44:5 -a payload.txt

---

ARP request from the MAC address 00:11:22:33:44:55 asking who has the IP address 192.168.0.1:

inject arp -i wlp5s0 -K 00:11:22:33:44:55 -S 192.168.1.50 -D 192.168.0.1 -r 1

---

IP packet from the IP address 192.168.1.40 to the IP address 192.168.1.1 with TTL of 48:

inject ip -S 192.168.1.40 -D 192.168.1.1 -T 48

---

TCP packet with the payload file payload.txt from the IP address 192.168.1.50 to the IP address 192.168.1.1 with the source port 4444, the destination port 80, and the SYN flag:

inject tcp -S 192.168.1.50 -s 4444 -D 192.168.1.1 -d 80 -f syn -a payload.txt

---

UDP packet with the payload file payload.txt from the IP address 192.168.0.2 to the IP address 8.8.8.8 with the source port 4444 and the destination port 53:

inject udp -S 192.168.0.2 -s 4444 -D 8.8.8.8 -d 53 -a payload.txt

---

ICMP packet with the IP address 192.168.0.2 to the IP address 8.8.8.8 with the ICMP type 8 (echo request) and code 0:

inject icmp -S 192.168.0.2 -D 8.8.8.8 -t 8 -C 0

---

Sniffing all supported network protocol packets:

inject sniff

---

Sniffing only TCP and UDP packets:

inject sniff -t -u
