A methodology is a decision loop, not a linear checklist. You gather facts, choose the cheapest action that could confirm or kill a hypothesis, record the result, and re-enter the loop. Phases below are named for orientation; in practice you drop back to enumeration every time something new appears — a share, a password, a hostname, a service banner. 2025–2026 context: This methodology is built for a landscape where identity is the new perimeter (OAuth, SAML, ADCS, cloud IAM), defenders automate containment (EDR, SOAR, automated account disabling), and exploits are increasingly deterministic (page-cache LPEs, parser differentials) rather than memory-corruption races. The loop is more important than ever: “Try harder” is not a strategy; “Read the source, check the clock, reuse the password” is.

Copy-paste command sheet for a general pentest or an OSCP-style exam: one block per phase, checkboxes for the steps, exact commands for the tool versions shipped on current distributions. It is the companion to the methodology — the methodology explains why and when, this page is what you actually type. Every command is a template: read it, substitute the variables, and check the precondition before running it. Version drift is the #1 cause of a “broken” cheat sheet. Recent tool releases changed flags in nxc, certipy, impacket, ligolo-ng, and hashcat. Before trusting a command: nxc --help, certipy <subcommand> -h, impacket-<tool> -h, hashcat --example-hashes. If your install predates mid-2026, several of the modules below (ADCS ESC17, nxc --ntds --use-vss, --remove-mic) will not exist.

A problem-first index of the recurring techniques that decide the boxes on the OSCP-like lab list. Each pattern is deliberately small: when to reach for it, the prerequisite check that must pass, the commands worth memorising, and the machines where it was the difference between stuck and rooted. It sits between three neighbours: the command checklist you run at the start of every box, the Linux, Windows and AD machine pages that walk one box end-to-end, and the “Cross-machine patterns” summary at the end of each machine page. This page is the layer that transfers: a technique is worth learning when you can name two machines it appears on and the condition that makes it fire. Nothing here is a walkthrough, and every command still needs its placeholders replaced.

One row per box for the whole OSCP-like list — 76 machines: 39 Linux, 18 Windows, 16 AD and 3 non-AD. Use it to pick a box by technique, to revise a path in 30 seconds, and to tick off what you have actually rooted. Detail lives in Linux, Windows and Active Directory; this page only routes you there. How to use this page Revision: read the row, then explain the path out loud without looking at the page. If you stall on the privesc cell, open the machine page. Progress: [ ] → [x] only when you rooted it unaided (no writeup, no hint). Reset a tick if you needed help. Choosing by technique: scan the Key tool or CVE and Privesc / path columns, not the names. The Study tracks below give ready-made orders. Gaps: the Coverage check shows which phase you have been avoiding — usually the one you keep skipping.

Consolidated index of 39 OSCP-like HTB Linux boxes — one path per box, the non-obvious steps that decide it, and the exact commands worth memorising. These are edge-case notes, not walkthroughs: every command must be adapted to the target (IPs, vhosts, ports, usernames, payload paths), and the source writeup remains the walkthrough of record. Companion pages: Command Checklist · Pattern Library · Methodology · Machine Index. How to use this page Start with a full TCP scan plus the UDP ports people skip (161, and NFS/mountd on dynamic ports), then fuzz vhosts before directory-brute-forcing the IP root. Treat every credential as a username+password pair and spray it at SSH, su and the application itself before hunting another bug. After landing a shell, run the triad — sudo -l, SUID/capabilities, and pspy/cron/timers — plus ss -tnl for localhost-only services. When an exploit fails, read the application’s own source and config (.git, backups, *.inc.php, JAR/ZIP contents) before assuming the target is patched. Enigma Path: NFS export /srv/nfs/onboarding holds an onboarding PDF with webmail creds → Roundcube mail001 → password reuse to a second mailbox → OpenSTAManager 2.9.8 support portal → www-data → DB hash → haris → OliveTin on 1337 → root.

Eighteen standalone Windows boxes from the OSCP-like list — one intended path each, the non-obvious step that decides it, and the exact command worth memorising. These are edge-case notes, not walkthroughs: every IP, hostname, port, user and payload path must be adapted to the target, and the linked writeup remains the walkthrough of record. Companion pages: Command Checklist · Pattern Library · Methodology · Machine Index. How to use this page Full port scan, then UDP. nmap -sT -p- --min-rate 5000 --max-retries 1 is the baseline; several boxes answer on nothing in the top 1000 (Chatterbox, Arctic) and services hide on UDP (AChat on 9256). Enumerate SMB and RPC before attacking. Null sessions, share listings (smbclient -N -L //IP when smbmap fails), and RID cycling (lookupsids, 1000–1050) often produce the userlist no wordlist would give you. Re-try every credential against SMB, WinRM, RDP, MSSQL and the application itself — including username-format variants (admin vs admin@domain, user vs DOMAIN\user). Then run whoami /priv, check service ACLs and writable service paths before any kernel exploit. Assume Defender and AppLocker. Prefer living-off-the-land, shell_exec over system, staged and encoded payloads; a payload that does nothing is usually AV or .NET-version mismatch, not a broken exploit. Markup Path: Default creds on the MegaShopping login → Order page posts raw XML to /process.php → XXE reads Daniel’s id_rsa → SSH → users-writable job.bat run by a SYSTEM schedule.

The AD half of the OSCP-like HTB list — one path per box, the step that actually decides it, and the exact command worth memorising. These are edge-case notes, not walkthroughs: every IP, domain, user and path must be adapted to your target, and the linked writeup remains the walkthrough of record. Companion pages: Command Checklist · Pattern Library · Methodology · Machine Index. How to use this page Assumed breach vs unauthenticated. Only five boxes hand you credentials at the start — Administrator (olivia:ichliebedich), Certified (judith.mader:judith09), EscapeTwo (rose:KxEPkKe6R8su), Puppy (levi.james:KingofAkron2025!) and Signed (scott:Sm230#C5NatH). For those, the first ten minutes are --shares, BloodHound, certipy find and per-service auth checks — not brute force. Everything else starts with null SMB/RPC, a web bug, or a share. BloodHound before exploitation. Collect with bloodhound-python -c all --zip (or bloodhound-ce-python) and read the Abuse Info of each edge; rights on the domain node show up as GetChanges/GetChangesAll, not as an edge called “DCSync” (Sauna). Every found secret is a reuse test. Fan out nxc smb/ldap/winrm/mssql/ftp with --continue-on-success; a service that fails is not the service that matters (Return: WinRM but no SMB admin; Administrator: FTP but no WinRM for benjamin). Try the actual account name when a config spells it differently (Sauna). ADCS, delegation and time. None of Active/Forest/Sauna/Flight/Return/Blackfield/Cicada/TheFrizz/Administrator/Monteverde exposes a CA — do not burn exam minutes on Certipy there. The ESC paths live in Escape (ESC1), EscapeTwo (ESC4→ESC1) and Certified (ESC9). Clock skew is the single most common time sink: sudo ntpdate <dc fqdn>, expect the VPN to drop, reconnect — but note that AS-REP roasting tolerates hours of skew (Sauna).
