The Register: Not all networks can handle AI traffic – and experts are sounding alarms. “AI is reshaping the demands on network infrastructure, and many organizations are not prepared – including some of the so-called neocloud providers offering AI services. A study by analyst biz Omdia finds that many rent-a-GPU providers have scaled up their compute infrastructure to handle AI workloads, […]

🦈 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.
