Explore how shells connect to the kernel as command line interfaces and compare zsh, bash, and sh on Kali Linux. Learn bind and reverse shells and remote setup with ssh.

Explore Kali Linux reverse shells in practice by cloning VMs, configuring a NAT network, and using netcat to listen on port 4444 and execute a /bin/sh on connection.

Compare telnet and ssh, noting telnet's port 23 plain text credentials versus ssh on port 22 with encryption, then configure ssh keys, enable pub key authentication, and disable root login.

Explore the z shell on Kali Linux, customizing the shell, enabling autocorrection, and leveraging tab completion, globbing patterns, and aliases to streamline terminal workflow.

Explore shells, reverse shells, and secure communication in Kali Linux, compare Telnet and SSH, and discover zsh features, preparing you for advanced command line use and penetration testing tools.

Learn vim, the command-line text editor, through hands-on basics: navigate with normal mode, insert and visual modes, perform copy, paste, delete, and split screens, and save or customize vimrc settings.

Explore nano in Kali Linux from scratch, a beginner-friendly text editor with a bottom cheat sheet, and learn essential shortcuts for editing, cutting and pasting, searching, saving, and exiting.

Master wget, a noninteractive network downloader for Kali Linux, to fetch files, download pages, and mirror websites from command line, using manual pages, piping, and recursive downloads with rate limits.

Learn curl, a command line tool for transferring data over http, https, and ftp to interact with servers and test APIs within Kali Linux cybersecurity workflows.

Explore John the Ripper, a tool to crack hashed passwords on Kali Linux using single-mode cracking, dictionary attacks, and rule-based word lists such as rockyou.

Explore Hashcat, a GPU-accelerated hash cracking tool with dictionary, brute force, and mask attacks, compare it to John the Ripper, and test sha1, MySQL five, and MD5.

Explore essential tools in Kali Linux, including vim and nano for editing, wget and curl for downloading, and password cracking with John the Ripper and Hashcat.

Explore five phases of penetration testing, ethical hacking, from reconnaissance to reporting, including active and passive information gathering, scanning with nmap, exploitation, post-exploitation, privilege escalation, and vulnerability reporting and recommendations.

Explore google dorking, a Kali Linux reconnaissance technique using advanced operators to reveal hidden directories, sensitive files, and vulnerable devices, with passive and active recon.

Download the OWASP broken web applications project from SourceForge and import its vmdk into VirtualBox, then configure NAT networking for the Kali VM to access the target web apps.

Use nmap to scan networks and map open ports and services. Learn how version detection and vuln scripts reveal CVEs on the OWASP VM.

Explore how DNS translates domains into IP addresses and how whois, dig, and ping aid reconnaissance in Kali Linux.

Apply Burp Suite to intercept http traffic and test a vulnerable web app. Configure Firefox proxy, install the Burp CA certificate, and run intruder for brute force login.

Enumerate hidden web pages with fuzzing and go-buster, using a word list and dictionary attack. Analyze different response codes and consider cookies for authenticated enumeration.

Duplicate a login page with wget, host it locally with Python and Apache, and capture credentials with Wireshark. Compare manual setup to automated tools like Blackeye and note phishing risks.
