Windows Medium machine - Voleur.

HTB Active Directory Microsoft's directory service for managing users, computers, and permissions across a Windows domain. Windows Linux Sudo Linux command for running as another user — misconfigured sudo rules are a common privilege escalation path. SSH Secure Shell — encrypted remote login, targeted via key theft, brute force, or misconfigured access. Nmap A network scanner used to enumerate open ports, services, and versions on a target. DNS The Domain Name System — translates hostnames to IPs; often leaks subdomains and internal naming during recon. NTLM Windows' legacy authentication protocol — vulnerable to relay and pass-the-hash attacks. WinRM Windows Remote Management — used for remote PowerShell access, often the lateral-movement endpoint on AD boxes. SMB Server Message Block — Windows file-sharing protocol, frequently abused for enumeration and lateral movement. Password Cracking Recovering a plaintext password from a captured hash via brute-force or wordlist attacks. BloodHound A tool that maps Active Directory trust relationships as a graph to reveal hidden attack paths to Domain Admin. LDAP Lightweight Directory Access Protocol — used to query Active Directory; often vulnerable to injection or anonymous binds.

Linux Intermediate machine - Updown.

HTB Linux Sudo Linux command for running as another user — misconfigured sudo rules are a common privilege escalation path. SSH Secure Shell — encrypted remote login, targeted via key theft, brute force, or misconfigured access. DNS The Domain Name System — translates hostnames to IPs; often leaks subdomains and internal naming during recon. PHP LFI Local File Inclusion — a web vulnerability letting an attacker read arbitrary files on the server. Git Brute Force Systematically trying many credential combinations until one succeeds. SUID A Linux permission bit that runs a binary as its owner — misconfigured SUID binaries are a classic privesc vector. Cronjob A scheduled task on Linux — often abused for privilege escalation when it runs as root with a writable script. RFI Remote File Inclusion — a web vulnerability allowing an attacker to include and execute a remote file.
