Ethical Hacking: Network Attacks

Learn how WHOIS reveals domain information such as who registered the website, when it expires, and name servers, enabling hackers to gather data for social engineering and pre-attack reconnaissance.

Explore how nslookup translates a website name into an IP address, defaults to IPv4, can show IPv6, and can query MX records for mail servers.

Explore how to use DNS dumpster to uncover subdomains and hosting details for a domain, and identify DNS records such as MX, A, and TXT.

Learn how Shodan serves as a web-wide search engine to discover technology stacks, devices, and vulnerable software versions, such as Apache, cameras, and Android remote access.

Learn how to identify devices on a network and test connectivity using the ping command to determine whether hosts respond online.

Telnet provides a basic command-line interface to connect to any computer across ports, revealing unencrypted data and software version information that can expose exploitable weaknesses.

Learn how netcat acts as both client and server to connect to IP addresses and ports or listen on a port such as 4444 for bidirectional communication.

Learn to use nmap to identify a host’s ip address and open ports, scan networks, and reveal services such as web servers on port 80 and ssh on port 22.

Attackers map the victim's IP, scan for open ports, and brute-force passwords using large word lists with Hydra against FTP and other services to gain access.

Explain how attackers bypass firewalls and use the router to connect victims to a cloud server. Enable a payload on the victim's computer to grant remote access.

Learn how to set up a remote listener and establish a reverse connection to a Mac OS X workstation, using cloud CPUs or a local network for remote access.

Demonstrates setting up a netcat listener to gain remote access to a Windows XP workstation, then interact with the target's command line and maintain the connection.

Discover how to hack a Linux workstation by configuring a listener, delivering a script, and establishing a reverse shell to gain full user access on the victim's Ubuntu system.

Generate a Windows executable with MSF Venom on Kali Linux to establish a reverse shell by configuring the target IP, port, and file format.

Demonstrates using exploits and a reverse shell to access a Windows workstation, then explores advanced commands, file system navigation, and capabilities like microphone, webcam, and other system controls.

Learn how packet sniffing on the same network intercepts data not encrypted and in clear text using tcpdump and Wireshark, potentially exposing usernames and passwords.
