Understand NETBIOS and SMB Attacks

The video tutorial covers the evolution of SMB versions from Windows 2000 to Windows 10, highlighting the security improvements in each version. It introduces tools in Kali Linux, such as NBTscan and enum4linux, for gathering network information and identifying vulnerabilities in SMB implementations. Additionally, it discusses using Nmap scripts for SMB discovery, emphasizing the importance of using the latest SMB versions to ensure security.

• SMB version 2.1

• SMB version 3.0.2

• SMB version 3.1.1

What is the primary function of the NBTscan tool in Kali Linux?

• To encrypt network traffic

• To scan for open ports

• To perform a denial-of-service attack

• To gather NetBIOS information

Which tool provides more detailed information than NBTscan?

• Wireshark

• enum4linux

• Metasploit

• Nmap

What kind of information can enum4linux provide about a Windows machine?

• Open ports and services

• User accounts and groups

• Firewall rules

• Installed software

What is the purpose of the SMB OS Discovery script in Nmap?
