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.
