#networktraffic — Public Fediverse posts

Ah, yet another thrilling deep dive into the arcane world of wire-level #sorcery 🧙‍♂️! Who knew that analyzing a #CLI tool's network traffic could be this exhilarating? 🚀 Spoiler: It's mostly just shouting "Sign in" and "Sign out" at you while you desperately search for relevance. 🔍

🦈 Wireshark Useful Filters – Quick Guide for Network Pros 🌐

Wireshark is the go-to tool for packet analysis 📡. With the right filters, you can cut through the noise and find exactly what matters 🔎. Here are some of the most useful ones every cybersecurity pro 🛡️ and network engineer ⚙️ should know:

✨ Host & IP Filters
ip.addr == 192.168.1.10 → traffic from/to one host 🖥️
ip.src == 10.0.0.5 → packets from a source 📤
ip.dst == 8.8.8.8 → packets to a destination 📥

✨ Protocol Filters
http → all HTTP traffic 🌍
dns → DNS lookups & responses 🔤
tcp / udp → filter transport layer 📡

✨ Port Filters
tcp.port == 443 → HTTPS 🔒
udp.port == 53 → DNS 📡
tcp.port == 22 → SSH 🔑

✨ Conversation Tracking
tcp.stream eq 5 → follow a single TCP session 🔄
http.request → show only client requests 📤
http.response → show only server responses 📥

✨ Error & Suspicious Activity
tcp.flags.reset == 1 → connection resets ⚠️
icmp → ping/echo packets 🛰️
ssl.handshake → TLS handshakes 🔐

⚠️ Disclaimer:
For educational & authorized use only. Always analyze traffic in labs or systems you manage. 🚫🔒

My favorite pentesting setup.

Today i'm setting up the #KaliLinux #Docker #container for my #ansible #playbook. This setup has some pretty cool advantages for me.

I can:

• access the shell and files using #SSH and #SFTP.
• customize the installation to the fullest extend using the #Dockerfile.
• easily route the #networktraffic through a #vpn using #gluetun.
• reproduce the setup (i love Docker).
• use GUI apps from that container using X11Forwarding or by installing a #vnc server.

This has been my favorite #pentesting setup so far for obvious reasons. I can access a fully configured pentesting environment on all my devices, always accessible and ready to go.

In case anyone is interested in the setup, it will be included in my ansible playbook, which will be published on this repository.

Don't mix up #WireShark and #WireGuard: One is for analyzing #networktraffic and the other one is for hiding and encrypting network traffic (besides other things).

And yes, I verbally mix them up often enough even though I know exactly which one does what. Seems to be a #dyslexia thing.

One example why to use strong #passwords for users who use file sharing over #SMB even when the file transfers are #encrypted.
If the SMB traffic is captured/eavesdropped, then the attacker can try to crack the user password.
The attacker is able to extract challenge/response values from the Session Setup and then use #passwordcracking tools such as #hashcat

If the attack is successful, the attacker will gain not only the access to the user account, but it is also possible to decrypt the captured SMB file transfers. There is lack of perfect forward secrecy in this encryption.

For more details and practical examples, see this blog post:

Recent #TryHackMe room inspired me to publish blog about Decryption of #SMB traffic

Summarized 3 methods of decryption in #Wireshark:
- with user password
- with NTLM hash
- without them, just by cracking the captured #network traffic

Hello everyone.
In today's article, we learn to listen to our own TCP/UDP packets using the Python socket model.

We wish everyone a good reading and working.

Egal ob KI, Machine Learning (ML), Erweiterte Realität (XR) oder Digital Twins - alle diese Technologien haben etwa gemeinsam: Sie sorgen dafür, dass der Datenverkehr weiter stark zunimmt. Glaubt man dem Global Network Traffic 2030 Report von Nokia, so wird der Datenverkehr zwischen 2022 und 2030 mit einer durchschnittlichen jährlichen Wachstumsrate (CAGR) von 22 bis 25 Prozent zunehmen.
