Dutch Osborne discusses port scanning using Node.js, noting that it can be done for fun or during security assessments where tools like NMAP are not allowed. He then introduces a demonstration of a Node.js port scanner and provides resources, including a link to his GitHub page containing a simple Node.js port scanner code.

2. About Me
• Cyber Security Engineer at Aleta Technologies
• Love to code (sometimes haha)
• I have a little over 600 video games in my steam library
(It’s a bad habit, kids. Don’t start it.)

3. Why In The World Would You Use Node.js For
Writing a Port Scanner?
• Fun.
• You are on one of “those” red team assessments. The ones where the
RoE do not allow you to use NMAP/Angry IP/Solar Winds/etc in your
pen test.
• Tired of writing port scanners in other languages (python would be
what I normally use).

4. DEMO TIME!
