LinkVortex writeup

LinkVortex is a Linux box that involves subdomain enumeration and source‑code disclosure via a .git directory. We will reuse hardcoded credentials, exploit a Ghost CMS arbitrary file read (CVE‑2023‑40028) to obtain SSH credentials, and escalate privileges through environment variable manipulation in a custom script.

Administrator writeup

Administrator is a Windows Active Directory box that demonstrates permission chaining, BloodHound enumeration, and password‑spraying. We will use a recovered PasswordSafe database for credential spraying, perform targeted Kerberoasting, abuse DCSync, and finally use pass‑the‑hash to gain domain administrator access.

Titanic writeup

Titanic is a Linux box that starts with a local file inclusion (LFI) vulnerability in a Flask web application. We will discover a subdomain, extract credentials from a Gitea instance, crack hashes, and escalate privileges via an ImageMagick configuration‑path vulnerability (GHSA‑8rxc‑922v‑phg8).

TheFrizz writeup

TheFrizz is a hybrid box that combines web exploitation, database credential extraction, and Active Directory lateral movement. We will exploit a Gibbon CMS RCE (CVE‑2023‑45878), extract and crack hashes, use Kerberos authentication, and abuse Group Policy Objects (GPO) for privilege escalation.

TombWatcher writeup

TombWatcher is a Windows Active Directory box that involves lateral movement through multiple user accounts, Kerberoasting, shadow credential attacks, and certificate template abuse. We will perform BloodHound enumeration, set a service principal name for Alfred, Kerberoast to obtain Alfred’s hash, then leverage GenericAll permissions to manipulate SAM, John, and CERT_ADMIN accounts, finally using ESC1 vulnerability to request a certificate as the domain administrator.
