scapy VS bettercap

Example Network Scanner Scapy

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:

I've coded my small ARP spoofer in Go because I love the language, though it can very well be coded in other languages, for example Python with Scapy.

Tshark can't do that. The Wireshark app does update its Conversations window pretty frequently when doing a live capture, so that might be a reasonable alternative. Otherwise you could probably also cobble something together yourself with a tool like scapy or some other Python library, but that would clearly be more work.

I don't know if you can do it within the gui, I don't see anything but perhaps a bit of Python code would do it. There is a python library called Scapy that may have functions to help you along the way.

you can do this with Bettercap

I've been learning some common lisp, reading through Practical Common Lisp, and it's really neat. People say the good ideas of lisp got adapted in other languages and sure that's true of garbage collection, lambda's and some others, but I'm seeing plenty incredible stuff I haven't seen elsewhere, the condition system that among other things lets you fix and resume your program on exception, real interactive development, flexible object system, macros way more understandable than in other languages with AST macros as in lisp the AST is simple, an expressive dynamic language at high level of ruby and python while being an order of magnitude faster performance. Quicklisp also is really neat, how many other package managers can load new dependencies without restarting your application? And I was learning it with idea that it's not just of historical or hobby interest but legitimately a good choice I can use for new programming projects today for many tasks, but I just learned something that makes it impossible for me to consider, which is complete lack of security of quicklisp. You go to the website and see sha256 hash and PGP signature for quicklisp download, awesome it seems at the security standard you expect for a package manager. But then the actual quicklisp client does all downloads over http with no verification. What this means in practical terms is basically if you use quicklisp, anyone on your local network can easily hack your computer, by MITM (man-in-the-middle) the traffic and serving you backdoored software when you install packages from quicklisp. mitm6 will MITM windows machines on normal networks, bettercap can MITM linux and os x on most networks. Aside from attackers on your local network there's plenty other scenarios, you can go near office of CL using company and set up a open WIFI access point with same name as company wifi and hack their developers, using quicklisp over something like Tor is extremely dangerous at present as it would let the exit node backdoor the packages you download, and then in less likely but still should be protected against scenarios is just if quicklisp.org or any router between you and it is compromised, you can be hacked.
