🚨 Iranian fingerprint inside American networks... And hacks that stayed hidden for weeks
Broadcom researchers have uncovered an advanced cyber-spying campaign carried out by the Iran-linked MuddyWater group, after observing its presence within the networks of several companies in the United States without drawing attention for some time.
Technical analysis has shown that attackers used a backdoor based on the Deno environment to run remote commands inside the infected systems, a style that provides high concealment because this environment is less used in traditional malware. Attackers also attempted to transfer data off targeted networks via Rclone tool to cloud storage...

🌐 Networking Basics Every IT Professional Should Know

If you're starting your journey in Networking, CCNA, or Cybersecurity, understanding these core concepts is essential. This quick guide covers some of the most important building blocks of modern networks.

📌 Key Networking Concepts

🔹 Network – Connects multiple devices to share data and resources.
Types include LAN, WAN, and MAN.

🔹 Switches – Connect devices within a Local Area Network (LAN) and forward frames based on MAC addresses.

🔹 Router – Directs data packets between different networks using routing protocols.

🔹 VLAN (Virtual LAN) – Segments a network into multiple logical...

Researchers in Japan have achieved a breakthrough that could transform the future of global connectivity. By pushing fiber-optic technology to its limits, they managed to send data at speeds faster than anything previously recorded, opening the door to a new era of internet performance. What makes this achievement even more remarkable is that it builds on existing cable infrastructure, meaning worldwide networks could one day be upgraded without starting from scratch.

This leap in speed has profound implications. From enabling real-time VR and immersive metaverse experiences to powering scientific research that requires instant data transfer, the possibilities are endless. Financial...

Did you know Jack Dorsey, the co-founder of Twitter, has launched a new messaging app that works without the internet

Instead of using Wi-Fi, mobile data, or cell towers, the app uses Bluetooth to connect phones directly to each other. Messages hop from one device to the next, forming a local network. No internet. No signal. No central servers.

What makes it different?
🔒 End-to-end encrypted (messages stay private)
👤 No phone number, no email, no account needed
🌍 Works even when networks are down or restricted

Why this matters:
This kind of technology can be critical during natural disasters,...

🔐 How HTTPS Works (Step-by-Step)
HTTPS = HTTP + TLS/SSL Security

It ensures secure communication between Client (Browser) and Server.

1️⃣ TCP Handshake (Connection Setup)
Before security, a reliable connection is needed:
Client → TCP SYN
Server → SYN + ACK
Client → ACK
✅ TCP connection established

2️⃣ Certificate Verification (Trust Building)
Client sends Client Hello
Server replies with:
Server Hello
SSL Certificate
Server Hello Done

🔍 Browser verifies:
Certificate Authority (CA)
Domain name
Expiry date

👉 Uses Asymmetric Encryption
Public Key (shared)
Private Key (server only)

3️⃣ Key Exchange (Security Setup)
Client generates a Session Key
Encrypts it...
