T50

Packet Injector

T50 is a packet injector tool designed for “Stress Testing” and performing TCP/IP protocol fuzzing. It is capable of sending all protocols, such as ICMP, TCP, and UDP, using a single socket and can be used to modify network routes. T50 is considered a powerful and unique tool for IT security professionals, as it helps in advanced “Penetration Testing.”

  • DoS and DDoS attacks simulator
  • Main supported protocols include TCP, UDP, ICMP, IGMP, etc.
  • Up to 1,000,000 pps of SYN Flood if using Gigabit network
  • Up to 120k pps of SYN Flood if using 100Mbps network

  1. T50 is a fast and efficient DDoS tool that operates on layer 4 and layer 7.
  2. It can generate a wide variety of DDoS attack patterns, including SYN flood, ACK flood, and more.
  3. This tool is known for its effectiveness and can quickly identify weak points in your network defenses.
  4. When utilized responsibly on Kali Linux, T50 can significantly enhance your system's security against DDoS attacks.

  1. Send sequentially the following fifteen (15) protocols :
    • ICMP - Internet Control Message Protocol
    • IGMPv1 - Internet Group Management Protocol v1
    • IGMPv3 - Internet Group Management Protocol v3
    • TCP - Transmission Control Protocol
    • EGP - Exterior Gateway Protocol
    • UDP - User Datagram Protocol
    • RIPv1 - Routing Information Protocol v1
    • RIPv2 - Routing Information Protocol v2
    • DCCP - Datagram Congestion Control Protocol
    • RSVP - Resource ReSerVation Protocol
    • GRE - Generic Routing Encapsulation
    • IPSec - Internet Protocol Security (AH/ESP)
    • EIGRP - Enhanced Interior Gateway Routing Protocol
    • OSPF - Open Shortest Path First
  2. It is the only tool capable to encapsulate the protocols (listed above) within Generic Routing Encapsulation (GRE).
  3. Send an (quite) incredible amount of packets per second, making it a "second to none" tool :
    • More than 1,000,000 pps of SYN Flood (+50% of the network uplink) in a 1000BASE-T Network (Gigabit Ethernet).
    • More than 120,000 pps of SYN Flood (+60% of the network uplink) in a 100BASE-TX Network (Fast Ethernet).
  4. Perform "Stress Testing" on a variety of network infrastructure, network devices and security solutions in place.
  5. Simulate "Distributed Denial-of-Service" & "Denial-of-Service" attacks, validating Firewall rules, Router ACLs, Intrusion Detection System and Intrusion Prevention System policies.

The T50 tool is a high-performance mixed packet injector primarily used for network stress testing and protocol fuzzing. Here are some examples of its usage :

  1. Stress Testing : T50 can simulate high traffic loads on network infrastructure to test its resilience. For example, you can use the --flood option to send a continuous stream of packets to a target IP, such as : t50 --flood 192.168.1.1
  2. This helps identify bottlenecks or vulnerabilities in the network.

  3. Protocol Testing : T50 supports multiple protocols like TCP, UDP, ICMP, and more. You can test specific protocols by specifying them in the command. For instance, to test TCP traffic : t50 192.168.1.1 --protocol TCP
  4. Packet Injection : T50 can inject custom packets into the network to test how devices handle unusual or malformed packets. This is useful for identifying potential security flaws.
  5. DoS Simulation : While not its primary purpose, T50 can simulate Denial-of-Service (DoS) attacks to evaluate how well a system can handle such scenarios. For example : t50 192.168.1.1 --flood --turbo

These examples demonstrate the versatility of T50 in network testing and security assessments. Remember to use it responsibly and only on networks you own or have permission to test!

Terminal Installation Commands ...

$ sudo apt-get update

$ sudo apt-get install t50


GUI Installation Steps ...
Linux
  1. Update the package database : sudo apt-get update
  2. Install T50 : sudo apt-get -y install t50

Ternatively, you can use apt or aptitude if preferred :

  • Using apt :
  • $ sudo apt update

    $ sudo apt -y install t50

  • Using aptitude (if not installed, install it first) :
  • $ sudo aptitude update

    $ sudo aptitude -y install t50

The T50 tool is primarily designed for Linux systems.

Windows

Use WSL (Windows Subsystem for Linux) : Install a Linux distribution (like Ubuntu) through WSL, and then install T50 within the Linux environment.

  1. Enable WSL Open PowerShell as Administrator and run : wsl --install
  2. This installs the default Linux distribution (Ubuntu) if WSL isn't already enabled.

  3. Launch WSL Open a Terminal and enter : wsl
  4. If needed, install a preferred Linux distribution.

  5. Update the Package Repository Inside WSL, update your system : sudo apt update && sudo apt upgrade -y
  6. Install Dependencies T50 may require additional packages. Install them using : sudo apt install git build-essential -y
  7. Download and Install T50 Clone the repository :
  8. $ git clone https://github.com/fredericopissarra/t50.git

    • Navigate into the directory : cd t50
    • Compile the tool : make
    • Move the binary for system-wide use : sudo mv t50 /usr/local/bin/
  9. Verify Installation Run : t50 --help
  10. If you see usage instructions, the installation was successful!

Virtual Machine : Set up a virtual machine (e.g., using VirtualBox or VMware) with a Linux OS and install T50 there.

MacOS
  • Use Docker : There is no official T50 image on Docker Hub.
  • Use a Virtual Machine : Similar to Windows, you can run a Linux virtual machine on macOS and install T50.

Terminal Uninstallation Commands ...

$ sudo apt-get remove t50

$ sudo apt autoclean && apt autoremove


GUI Uninstallation Steps ...
Linux
  1. Remove only the T50 package : sudo apt-get remove t50
  2. Remove T50 along with its dependencies : sudo apt-get -y autoremove t50
  3. Purge T50 configurations and data : sudo apt-get -y purge t50
  4. Remove T50 configurations, data, and all dependencies : sudo apt-get -y autoremove --purge t50
Windows
  1. Remove the T50 Binary : sudo rm /usr/local/bin/t50
  2. Delete the Repository Folder Navigate to where you cloned T50 and remove it : rm -rf ~/t50
  3. Remove Dependencies (Optional) If installed just for T50, remove with :
  4. sudo apt remove --purge git build-essential -y

  5. Clean Up Unused Packages :
  6. $ sudo apt autoremove -y

    $ sudo apt clean
