HackTheBox - Sauna

Sauna from HackTheBox is an easy rated machine, in which we first identify an Active Directory user through a list of team members on a web page and get credentials for it through ASREP Roasting. We then identify a service account and find its password in the AutoLogon credentials. That user has DCSync privileges, which we can use to dump the hash of the Administrator and use that hash to get Administrator access. Read more

HackTheBox - Forest

Forst from HackTheBox is a Windows box, in which we first enumerate users via SMB and then use ASREP Roasting to get AD credentials of a service account. After that, we can add that account to an Exchange group that allows the assignment of DCSync privileges in order to dump NTLM hashes. Port Scanning The open TCP ports indicate that we’re dealing with a domain controller for the htb.local domain running Windows Server 2016: Read more

INE Lab - From XSS to Domain Admin

This lab starts by exploiting a stored XSS vulnerability and a vulnerable Java browser plugin to get a (unprivileged) remote shell on one of the company’s internal network machines. In a next step, using the socalled Group Policy Preferences (GPP) vulnerability, it’s possible to get local administrator credentials. Bypassing UAC allows to further escalate the privileges to SYSTEM and force a domain administrator to login to the machine, by preventing an importing application to work,so that the user will contact IT support.
