Purple Knight

Happy birthday to...me! 🎉🎂 Today marks another year of scanning hybrid identity environments, uncovering Indicators of Exposure (IoEs) and Indicators of Compromise (IoCs), and helping IT defenders fortify their #ActiveDirectory, Entra ID, and Okta security. Over the years, I've assessed tens of thousands of environments, identifying risky configurations and security gaps that could give attackers the foothold they seek. With 185+ security indicators mapped to MITRE ATT&CK and ANSSI frameworks, I don't just detect threats: I provide guidance so organizations can reduce their attack surfaces with prioritized remediation. And I’m just getting started. 💪 My birthday wish this year is to empower more IT teams with actionable identity security insights. Want to celebrate with me? 🥳🎁 Give yourself the gift of security — run a Purple Knight scan today. https://lnkd.in/d5xDHSvq #HappyBirthdayToMe #TheRealPurpleKnight

You know it's a good night when you start ordering a beer and somehow end up bartending yourself. #TheRealPurpleKnight is always ready to step in and save the day. Flashback Friday to last week, when all of Semperis came together to fuel our culture and spark new ideas. From tackling cybersecurity threats to comparing cocktails, we know that a strong, connected team is the foundation of everything we do. Nothing strengthens a team like stepping away from our screens and coming together IRL. Will you be at our next get-together? Join #TeamSemperis 🤝 https://lnkd.in/gYcvjUax Marco Magnaguagno, Rory Douglas, Jelena Begena, Chris Eves, Nico Devoti, Matt Hawkins, Jessica Sutton, Rocío Oñate Dancausa

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.

Imagine a rogue contractor sneaking into your city’s planning office and quietly altering blueprints to critical infrastructure. That’s #DCShadow, an attack where adversaries impersonate a domain controller to make undetected changes to your Active Directory. 🛠️ Your #ActiveDirectory is the control hub of your organization —your city— and safeguarding it means protecting those blueprints. 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. Protect your organization. Trust #TheRealPurpleKnight https://lnkd.in/d5xDHSvq P.S. 👕 Another shirt entered the Semperis Swag Store yesterday. Check it out 👀 https://lnkd.in/g6A84g7u Want this shirt?

It's a show-your-love kind of season, and we're showing it to our community with T-Shirt giveaways this month (a different shirt every week!). 👕💜 This shirt 👉 https://lnkd.in/g3rjzqZU 👈 is fresh in the Semperis Swag Store and two lucky winners can earn one by commenting below on what they like most about Purple Knight. Why stop there? Head over to Forest Druid's channel for another shirt giveaway (and for the other half of this picture): https://lnkd.in/etaMMj5e #TheRealPurpleKnight and #LadyOfThePerimeter go together like wine and cheese (perfect pairing) or tomato & basil (zesty).

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

Not all roasting happens around a campfire with marshmallows. 🔥🍡 In cybersecurity, #ASREPRoasting is how attackers exploit accounts with Kerberos Pre-Authentication disabled to crack passwords offline.

With a free security assessment, you can uncover hidden risks and keep your identity store safe from the flames.
