NetBIOS

Okay.

Same goes with the NetBIOS.

So with the NetBIOS, you can get the information because NetBIOS is open for entire network because uh with the help of net wires entire system in the network generally communicate with each other so this port will always be open you can use an mb lookup and you can find the detail and you can get to know which system is workspace this system is uh client this system is server this system is like master browser or browser election services where it is running all information you can get it from this one command and with the help of this lady

okay

OK, sometime it's revealed the original MAC address, but here zero zero zero is giving its mean this is not a MAC address.

Heads up."

Is that, like, some, some, like, NetBIOS thing or something? That sounds like some very old school pre-IP networking thing.

I feel like I used to...

W- people would goof around with it, sending messages, like, at my early job to other computers.

You bypass the edge defenses completely.

You will see a terrifying amount of open ports, NetBIOS broadcasts, internal routing protocols, all because you are operating from a zone of inherent trust.

But if I go down the street to a coffee shop, hop on their public Wi-Fi, and point my scanner at the company's public IP block.

Then you are now conducting a penetration test from an external perspective, and honestly, you'll probably see almost nothing.

Now, right below the cryptography, we hit layer five, the session layer.

Protocols like NetBIOS, RPC, and sockets.

What exactly constitutes a session in this context?

A session is a persistent, stateful dialogue between two machines.
