Python Networking: TCP and UDP
In the last installment we looked at IP headers. One thing you might have seen missing is the port numbers. That's pretty important for making an internet connection. Well it turns out that IP tends to encapsulate other protocols (which is why it has protocol as part of the header). In this article we'll be looking at two popular protocols for internet traffic: TCP and UDP. Before we begin though install scapy which we'll be using to make things easier, and dnslib that will be used during the UDP section:

Is it possible to send raw data over an IP network, not encapsulated in TCP or UDP?

Pros and Cons of Rust for Cybersecurity
But, due to the young ecosystem, Rust isn't often the best choice for the 2nd category. There are exceptions: while working on a ROP exploitation CLI tool, I was surprised to find the top 3 fastest x86-64 disassemblers are all written in Rust. But other languages just have more mature security ecosystems. Python in particular has some amazing libraries like scapy and bindings for yara.

What's the "best" coding language to know/learn?
You can also manipulate them in higher languages or scripting such as Python. Check out Scapy as a good example of constructing packets from scratch. Python is powerful and also worth learning.

Has anyone ever had their homelab or network hacked? What happened?
Nope, this doesn't work any more. Shodan checks all ports (so any attackers using data from Shodan already know which ports you have open), and tools like masscan (https://github.com/robertdavidgraham/masscan) let you portscan the entire IPv4 address space in less than 10 minutes.

Private server intruded
https://github.com/LogoiLab/mcsl https://github.com/robertdavidgraham/masscan
The discord user at the time used the tool "Masscan" to scan every 25565 port on the internet, he claims he was able to get the entire internet scanned in just a few minutes with a 512MB buyvm slice.
- PSA: Masscan has changed his IP. Please block the new one on your firewall! Its likely our vps reporting worked.

Is this something i should worry about? Its whitelist, online mode, and the ip/user has been banned. Its been happening for a week now
Masscan is a tool for scanning large segments of the internet for open ports. I've used it previously and it's not an inherently malicious tool.
