The youtube video below provide a quick example of how Nebula can speed up the process of identifying vulnerabilities
Enhanced Vulnerability Identification and Exploitation: Nebula will execute a series of scripts to detect potential vulnerabilities. Leveraging AI-driven algorithms, it will subsequently try to exploit identified vulnerabilities.
Effortless Tool Usage with Natural Language: No need to remember intricate commands or switches for various tools. With Nebula, you can seamlessly communicate your intent, whether it's initiating an NMAP scan or any other task. Let Nebula translate your natural language into precise tool commands.
Direct Command Line Access: Execute suggested commands without having to copy and paste.
Monitor the IP addresses and ports you've engaged with during a penetration test using the Nebula-Watcher tool to ensure complete coverage. Visit nebula-watcher for more information.
Disclaimer: Only NMAP is currently supported for smart analysis of tool output.
Smart Analysis of Tool Outputs: Whether it's the open ports from an NMAP scan or results from other tools, Nebula provides tailored suggestions to further investigate and identify potential vulnerabilities.
Search for commands that help identify Vulnerabilities: Easily search and retrieve commands that aid in detecting vulnerabilities across a range of services. Whether you're dealing with HTTP, FTP, or SMB, Nebula guides you through.
Nebula is an AI-powered assistant specifically designed for the field of ethical hacking. It provides a unique capability for users to input commands using natural language processing, facilitating a seamless transition from intent to execution.
Additionally, Nebula offers a command search engine. Ethical hackers can effortlessly search for services, ports, or specific terms. In response, Nebula provides curated suggestions on commands that can aid in identifying potential vulnerabilities.
Currently, Nebula is integrated with and supports the following ethical hacking tools:
Our roadmap envisions Nebula's continuous expansion to incorporate the majority of the tools leveraged by ethical hackers globally. This commitment ensures that our users remain at the cutting edge of cybersecurity endeavors.

You can install exploitdb via APT or GIT, note that that will affect what you set the --exploit_db_base_location as.
Linux (debian based):
APT based install:
sudo apt -y install exploitdb
GIT based install:
sudo git clone https://gitlab.com/exploit-database/exploitdb.git /opt/exploitdb
sudo ln -sf /opt/exploitdb/searchsploit /usr/local/bin/searchsploit
sudo apt install -y libreadline-dev
Linux (debian based):
sudo apt install -y wget
The easiest way to get started is to use the docker image. Please note that the ZAP model is NOT supported in the docker image. If you would like to use ZAP please install the package using pip.
PRO TIP: Regardless of if you are using the docker or pip version, always run nebula in the same folder so that it doesn't have to download the models each time you run it.
Docker:
Pulling the image:
docker pull berylliumsec/nebula:latest
Running the image without GPU:
docker run --rm -it berylliumsec/nebula:latest
To avoid downloading the models each time you run the docker container, mount a directory to store the models like so:
docker run --rm -v "$(pwd)":/app/unified_models_no_zap -it berylliumsec/nebula:latest
Running the model with all GPU(s)
docker run --rm --gpus all -v "$(pwd)":/app/unified_models_no_zap -it berylliumsec/nebula:latest
docker run --rm --gpus all -v "$(pwd)":/app/unified_models -it nebula:latest
For autonomous mode and to use the default vulnerability scan:
docker run --rm --gpus all -v "$(pwd)/targets.txt":/app/targets.txt -v "$(pwd)"/unified_models:/app/unified_models -v $(pwd)/targets:/app/targets -it nebula_testn:latest --autonomous_mode True --targets_list /app/targets.txt
For autonomous mode and to use your own nmap vulnerability scan:
docker run --rm --gpus all -v "$(pwd)/targets.txt":/app/targets.txt -v "$(pwd)"/unified_models:/app/unified_models -v $(pwd)/targets:/app/targets -it nebula_testn:latest --autonomous_mode True --nmap_vuln_scan_command="nmap -Pn -sV --exclude-ports 21 --script=vulscan/vulscan.nse" --targets_list /app/targets.txt
PIP:
pip install nebula-ai
To run nebula simply run this command:
nebula
For performing operations that require elevated privileges, consider installing via sudo
sudo pip install nebula-ai
Then run:
sudo nebula
OPTIONAL nebula-watcher installation
PIP:
To install nebula-watcher:
pip3 install nebula-watcher
Docker
Pulling the image:
docker pull berylliumsec/nebula_watcher:latest
Running the docker image :
docker run --network host -v directory_that_contains_nmap_results/nmap_plain_text_or_xml:/app/results -v where/you/want/the/diagram:/app/output berylliumsec/nebula_watcher:latest
To change the diagram name from the default:
docker run --network host -v directory_that_contains_nmap_results/nmap_plain_text_or_xml:/app/results -v where/you/want/the/diagram:/app/output berylliumsec/nebula_watcher:latest python3 nebula_watcher.py --diagram_name /app/your_diagram_name
For optimal performance and to ensure access to the most recent advancements, we consistently release updates and refinements to our models. Nebula will proactively inform you of any available updates to the package or the models upon each execution.
PIP:
pip install nebula-ai --upgrade
pip3 install nebula-watcher --upgrade
Docker:
docker pull berylliumsec/nebula:latest
docker pull berylliumsec/nebula_watcher:latest
In this beta release, there are three primary applications for Nebula:
Using the autonomous mode, ethical hackers can supply a list of targets in a file named targets.txt. Nebula will run an NMAP vulnerability scan and then attempt to exploit the vulnerabilities using a combination of scripts and AI.
Within the search engine capability, ethical hackers can input port numbers or specific service names. In return, they will receive recommended commands to assist in the identification of potential vulnerabilities.
Pro Tip: For optimal results, search using service names or port numbers. This approach is more effective than entering a full sentence or broad query.
DISCLAIMER: The results provided by this tool may contain inaccuracies or may not be suitable for all scenarios. We highly recommend users to review and, if necessary, modify the suggested commands before executing them. Proceed with caution and always ensure you are acting within legal and ethical boundaries Queries can be presented naturally to the AI-driven assistant, which then translates them into specific commands.
Nebula can process results from NMAP scans (plain text or XML format) and suggest commands to run to detect vulnerabilities on services running on open ports.
Using the optional Nebula-Watcher, ethical hackers can automatically monitor the IP addresses and ports that they have engaged with during a penetration test to ensure maximum coverage .

Nebula can be run in autonomous mode or manual mode.
Nebula can be run in autonomous mode or manual mode.
To activate the autonomous mode, run:
nebula --autonomous_mode True
By default it will run the vuln, exploit, vulnscan, service detection -sV, and treat the host as online -Pn. You can override this by passing in your own nmap command and scripts:
nebula --autonomous_mode True --nmap_vuln_scan_command 'nmap -Pn -sV --script=your_script'
There is no need to add output flags such as -oX and -oN as those will be automatically added.
Nebula will run an initial vulnerability scan, parse the results, attempt to discover more vulnerabilities. Your targets should be placed in a plain text file
titled targets.txt. This is also customizable by using the --targets_list arg:
If Nebula recognizes any CVEs, it will try to exploit them. By default, the commands are limited to 1 commands per service/port. You can set the number of commands like this:
For up to 5 commands per service with open ports:
nebula --autonomous_mode True --attack_mode raid
To run every possible command per service with open ports:
nebula --autonomous_mode True --attack_mode war
If you want to do a dry-run of autonomous mode so that it does not attempt to exploit any vulnerabilities, set testing mode to True:
Note that testing mode will still perform a vulnerability scan, but it will not attempt to discover more vulnerabilities or attempt to exploit them
nebula --autonomous_mode True --testing_mode True
For bruteforce/password spraying attacks (if available or recommended by AI), provide these files usernames.txt and passwords.txt in the directory where you run nebula from.
Depending on how many IP addresses you provide, you may have several files to review. After Nebula is done in autonomous mode, it will drop into manual mode where you can view the results.
Nebula will try to execute available Metasploit modules using the standard remote ports, your local IP (or whatever ip you specify via args), and a random port. Even if you provide incorrect arguments to Metasploit, it won't shut down; it'll just notify you of the error. Hence, we've included placeholders for certain arguments, whether or not they're required.
{{ LHOST }}
{{ RHOST }}
{{ RPORT }}
{{ LPORT }}
In upcoming versions, we aim to improve this feature. As with other features, you can check out the outcomes in the view previous results menu option. For a deeper dive, launch the msfconsole and customize as needed. Our primary objective with the autonomous mode is to pinpoint exploits and demonstrate a quick proof of concept (POC) whenever possible using.
Note that results will only generally be written to a file if it is not empty.
Upon initial access to Nebula, users are greeted with several options:
Enter a New Command: This prompt allows users to input commands using natural language. Subsequently, the system predicts and suggests a command for execution. Users have the discretion to either execute the generated command as is or modify it. After initiating the command, they can choose to await its completion or proceed with other tasks. Queries should be formulated as commands rather than questions, see the natural language examples section for more information.
Pro Tip: In the beta version, for optimal performance, limit your queries to a combination of up to two switches.
In the above screenshot, the user asks the NMAP model to perform a top 10 port-scan on 192.168.1.1.
View Previous Results: After a command's execution, users can review the output via this option.
In the above screenshot, the user reviews the output of the top 10 port-scan.
Process Previous Results: Currently optimized for NMAP results (in plain text or XML format), Nebula enables users to select previous scan findings and obtain command suggestions to assess potential vulnerabilities of uncovered ports. Users have the flexibility to select a suggested command, modify it if needed, and execute. Support for results from other tools is planned for future releases.
In the above screenshot, the user asks Nebula to process the results of the top 10 port scan, Nebula provides suggestions on what commands to run, and the user chooses suggestion number #8 and runs the corresponding command after editing it.
In the above screenshot, the user views the results of running the suggested command. In this case, the result is a list of HTTP methods supported by 192.168.1.1.
Select a Model: Users can choose from one of the three available natural language processing models (note that the actual name of the models/version may vary from what is seen in this screenshot).
Search by keywords: By leveraging this feature, users can input keywords—such as port numbers or service names—and obtain command suggestions to identify vulnerabilities related to that specific service.
Pro Tip: For optimal results, search using service names or port numbers. This approach is more effective than entering a full sentence or broad query.
Results Storage: A folder named results is created (if it does not already exist) in the working directory where nebula is invoked.
Escape prompt screen without entering a prompt: To escape the prompt screen without entering a prompt, simply hit the enter key.
NMAP:
Note that for nmap commands, -oX and -oN are automatically appended. The plain text version is for you to be able to easily read while the xml version is for processing, please do not remove them
Examples:
CRACKMAPEXEC:
For crackmap, always include a username and a password in your prompt or indicate that you would like to use a null session:
ZAP:
The ZAP model currently only supports "full scan". Be sure to use the terms full scan in your commands.
