Nuclei is a tool that allows you to scan web targets for various vulnerabilities and misconfigurations using predefined templates¹. Here are 10 powerful one-liners that you can use with Nuclei to find interesting and potentially exploitable issues:

  • Scan for all CVEs in a target list: cat targets.txt | nuclei -t cves/ -o results.txt

  • Scan for all exposed panels in a target list: cat targets.txt | nuclei -t exposed-panels/ -o results.txt

  • Scan for all subdomain takeovers in a target list: cat targets.txt | nuclei -t subdomain-takeover/ -o results.txt

  • Scan for all XSS vulnerabilities in a target list: cat targets.txt | nuclei -t xss/ -o results.txt

  • Scan for all SSRF vulnerabilities in a target list: cat targets.txt | nuclei -t ssrf/ -o results.txt

  • Scan for all SQL injection vulnerabilities in a target list: cat targets.txt | nuclei -t sqli/ -o results.txt

  • Scan for all open redirects in a target list: cat targets.txt | nuclei -t redirects/ -o results.txt

  • Scan for all misconfigured CORS policies in a target list: cat targets.txt | nuclei -t cors/ -o results.txt

  • Scan for all prototype pollution vulnerabilities in a target list: cat targets.txt | nuclei -t prototype-pollution/ -o results.txt

  • Scan for all RCE vulnerabilities in a target list: cat targets.txt | nuclei -t rce/ -o results.txt

Top 5 Tools for CTFs

Capture the Flag (CTF) competitions are a great way to test and improve your cybersecurity skills. They involve solving a variety of challenges, such as hacking into websites, cracking passwords, and reverse engineering malware.

To be successful in CTFs, it's important to have a good understanding of a variety of cybersecurity topics, as well as the right tools. Here are our top 5 picks for the best CTF tools:

  1. Burp Suite

Burp Suite is a powerful web application security testing tool. It can be used to perform a variety of tasks, including intercepting and modifying HTTP requests and responses, scanning for vulnerabilities, and fuzzing.

  1. Ghidra

Ghidra is a free and open-source reverse engineering tool developed by the National Security Agency (NSA). It can be used to disassemble and analyze machine code, as well as to debug and create software exploits.

  1. Nmap

Nmap is a network mapping and security scanning tool. It can be used to identify all of the devices on a network, as well as the services they are running and the ports they are open on.

  1. SQLMap

SQLMap is an automated SQL injection and database takeover tool. It can be used to exploit SQL injection vulnerabilities in web applications and gain access to underlying databases.

  1. Python

Python is a general-purpose programming language that is widely used in the cybersecurity community. It is a good language for learning and scripting, and it can be used to solve a variety of CTF challenges.

In addition to these tools, it is also important to have a good understanding of the Linux command line and basic networking concepts.

Here are some additional tips for success in CTFs:

Practice regularly. The more CTF challenges you solve, the better you will become at it. Work with a team. CTFs are often more fun and successful when you work with others. Don't be afraid to ask for help. There are many people who are willing to help beginners learn about CTFs and cybersecurity. With the right tools and skills, you can be successful in your next CTF competition!
