Hack The Box Machine Breakdown: Rusty htb writeup hackthebox

The latest HTB machine, RustyKey, is a high-difficulty Windows box built around a realistic Active Directory (AD) attack chain. From the name and icon alone — an aged, possibly compromised key — we’re immediately pulled into the mindset of legacy access and mismanaged identity security.

The box drops you directly into the action with a valid set of credentials:

Username: rr.parker  
Password: 8#t5HE8L!W3A

That tells us one thing: enumeration and abuse of identity-based access will be central to this box.

The metaphor is clear: A key that still opens doors, but shouldn't.

This sets the tone for an attack surface involving:

• Legacy accounts
• Password reuse
• Misconfigured permissions
• Credential abuse across the domain

In corporate environments, these are all too common — and often overlooked by blue teams.

With credentials in hand, here's what we recommend:

✅ Validate Credentials

SMB: smbclient -L <IP> -U "rr.parker%8#t5HE8L!W3A"
WinRM: evil-winrm -i <IP> -u rr.parker -p '8#t5HE8L!W3A'

• LDAP binding
• RPC or WMI access

🔧 Enumerate the Domain

• rpcclient, net user /domain
• BloodHound/SharpHound
• ldapsearch

Manual recon with:

• whoami /priv
• net group /domain
• gpresult /R
• Get-ADUser, Get-NetUser, etc.
