Hashcat Potfiles and Output Files
In this lab, you will learn how to manage and interpret the results of a Hashcat cracking session, focusing on the potfile, showing cracked passwords, and isolating uncracked hashes.
Linux
Hashcat Hashing Fundamentals
In this lab, you will learn the fundamentals of hashing, including common hash types, how to generate a hash, and how to prepare for a basic Hashcat attack.
Linux
DAY 07: The Network Navigator
In this challenge, you'll step into the role of a network administrator to diagnose and resolve common network issues on a Linux server using essential command-line tools.
Linux
SMB Enumeration and Guest Access
In this lab, you will learn to perform Server Message Block (SMB) enumeration. You'll use `nmap` to identify the SMB service, exploit a guest access misconfiguration with `smbclient`, and retrieve a flag from a shared directory, simulating a common network vulnerability.
Linux
HTTP Enumeration and Directory Traversal
In this lab, you will learn to perform HTTP service enumeration and exploit a directory traversal vulnerability. You'll use `nmap` to identify a web server, then use `curl` to read a restricted file outside the web root and capture the flag.
Linux
Hashcat Dictionary Attacks
In this lab, you will learn how to use Hashcat to perform a dictionary attack to crack a password hash.
Linux
DAY 08: The Software Steward
In this challenge, you'll step into the role of a System Administrator to manage software packages on a Linux server, including updating, installing, verifying, and removing applications.
Linux
Hashcat Installation and System Benchmark
In this lab, you will learn how to install Hashcat, the popular password recovery tool, on a Linux system. You will also perform a system benchmark to measure its performance.
Linux
DAY 09: The Backup Sentinel
In this challenge, you'll act as a system administrator to master Linux backup and recovery, protecting critical data using `tar` and `cron`.
Linux
User Account Creation
In this lab, you will learn the fundamental Linux commands for user account management, including creating, modifying, and deleting user accounts, and granting administrative privileges.
Linux
Nmap Scanning and Telnet Access
In this lab, you will learn the basics of network enumeration. You'll use `nmap` to scan a target for open ports, identify a vulnerable Telnet service, and gain access to retrieve a flag, simulating a basic penetration test.
NmapLinux
Rsync Enumeration and Anonymous Sync
In this lab, you will learn to enumerate and exploit a misconfigured Rsync service. You'll use `nmap` to detect the service, connect anonymously to sync files from a remote target, and retrieve a flag, highlighting risks in backup synchronization services.
Linux
RDP Enumeration and Weak Password Access
In this lab, you'll enumerate Remote Desktop Protocol (RDP) services, identify vulnerabilities, and gain access using weak credentials. Use `nmap` for scanning, `xfreerdp` for connection, and retrieve a flag from the remote desktop session.
Linux
Telnet Brute Force and Weak Credentials
In this lab, you'll enumerate weak credentials for a Telnet service using a wordlist. You will scan with nmap, use hydra for a brute-force attack, and gain access to a target system to retrieve a flag, highlighting the risks of weak passwords.
Linux
Hashcat Brute-Force with Mask Attacks
In this lab, you will learn how to use Hashcat's powerful mask attack feature. You'll explore built-in and custom character sets to crack passwords with known patterns, and compare its efficiency against traditional dictionary attacks.
Linux
FTP Enumeration and Anonymous Access
In this lab, you will learn the basics of network enumeration and file transfer protocol exploitation. You'll use `nmap` to scan a target for open ports, identify a vulnerable FTP service, gain anonymous access, and retrieve a flag, simulating a basic penetration test.
NmapLinux
DAY 06: The Process Overseer
In this challenge, you'll act as a system administrator to manage and monitor Linux processes, from listing and prioritizing them to handling misbehaving and background tasks.
Linux
DAY 10: The Script Artisan
In this challenge, you will step into the role of a system administrator to write a powerful shell script that automates file management tasks, learning about variables, conditionals, and loops along the way.
