Unicornscan is a new information gathering and correlation engine built for and by members of the security research and testing communities. It was designed to provide an engine that is Scalable, Accurate, Flexible, and Efficient. It is released for the community to use under the terms of the GPL license.


It currently has hundreds of individual features, a main set of abilities include:

  • Asynchronous stateless TCP scanning with all variations of TCP Flags.
  • Asynchronous stateless TCP banner grabbing
  • Asynchronous protocol-specific UDP Scanning (sending enough of a signature to elicit a response).
  • Active and Passive remote OS, application, and component identification by analyzing responses.
  • PCAP file logging and filtering.
  • Relational database output.
  • Custom module support.
  • Customized data-set views.


Unicornscan comes pre-installed in Kali Linux. We can easily install if it installed:

# update your system
sudo apt update && sudo apt upgrade
# install unicornscan
sudo apt install unicornscan -y


Options: Get all available options:

unicornscan -h


unicornscan <options> <target>

TCP Scan: Perform a TCP SYN scan:

unicornscan -msf –v -I IP_ADDRESS/24

UDP Scan: Perform a UDP scan on a whole network range:

unicornscan –mU –v -I IP_ADDRESS/24

At the time of performing scans with unicornscan, we can see the packets on Wireshark.

That’s it. Thanks for reading.
