What if I told you that there's a spy with silent access to your organization’s central filing system? What if you followed my lead and discovered that spy copying every confidential file within the vault housing your filing systems? That's what #DCSync looks like in Active Directory. By impersonating a domain controller, that spy —an attacker— can extract sensitive data, including user credentials, without raising alarms. Your #ActiveDirectory holds the keys to your organization, and a successful DCSync attack can leave it exposed. That's where you bring me in. I'll identify accounts with permissions that could perform a DCSync attack, which helps you address flagged accounts before attackers can exploit them.

Purple Knight acts as your vigilant city inspector, uncovering hidden threats like DCShadow and protecting your city like Batman watches over Gotham. Secure your city plans.

Imagine a VIP guest list at an exclusive event. ?? It’s meant to ensure only certain individuals can enter the event venue. But what if someone slyly slips his or her name on "The List?" That person could gain special access without anyone noticing. #AdminSDHolderModification gives your uninvited guest entry to the event, complete with an open bar and swag bags. #AdminSDHolder is a mechanism designed to protect privileged accounts in Active Directory. If attackers manipulate it, they can secure long-term control over your environment. AdminSDHolder misuse can be subtle and difficult to spot, leaving your most sensitive accounts exposed. With Purple Knight guarding your VIP list, he can scan for signs of tampering (bribes not accepted!), helping you identify where the guest list might have been altered so you can take action. Protect your VIPs. Trust #TheRealPurpleKnight to uncover hidden threats and "guests" who shouldn't be on your VIP list.

If your castle walls are tall and strong, but your gate hinges are rusty, an attacker can walk right in. No scaling the walls, no breaching the barricades. That’s #ZeroLogon, a vulnerability that lets attackers bypass authentication on your domain controller with zero effort if your defenses aren’t up to date. ?? Your #ActiveDirectory is the heart of your IT kingdom, and keeping it secure means more than just maintaining a wall. Installing the latest security patches on your domain controllers is like reinforcing those gate hinges to keep intruders out. Finding those rusty hinges in a big castle, however, can be challenging. #TheRealPurpleKnight, your loyal champion, scans your castle walls for vulnerabilities like ZeroLogon and points out exactly where you need to strengthen your defenses. https://lnkd.in/d5xDHSvq Read the blog: Zerologon Exploit Explained ?? https://lnkd.in/gJckBHJP

Kerberos, the legendary three-headed dog, was meant to keep the dead in the underworld. But in your #ActiveDirectory, Kerberos attackers are finding ways to distract this guard dog so they can sneak past. ?? ?? ?? ?? #Kerberoasting is how attackers target accounts with a Service Principal Name (SPN). They request a service ticket, export it, and crack it offline to reveal weak passwords. When that happens, your trusted three-headed defender becomes a puppy ready for a cuddle. Keep your Kerberos guard dog on high alert with help from #TheRealPurpleKnight to identify Kerberoastable accounts. ??? Read the blog: Kerberoasting Explained ?? https://lnkd.in/gF5ZfF6H
