This is Jim Sykora, Trimarc Security Consultant and author of an awesomesauce white paper, "Owner or Pwned.” Jim smashes a year’s worth of research into 54 pages, complete with code snips, screenshots, and of course, Kenny Loggins references. Read the white paper to learn about discovering and remediating AD object ownership issues: https://lnkd.in/eNScCVse And since it’s Day 26 of #30DaysOfVision, we’d be remiss if we didn’t mention that Trimarc Vision checks for the ability to take ownership of privileged objects in #ActiveDirectory. Why is this important? Well, the default behavior in Active Directory allows the Owner of an AD Object to fully control that Object. Do you know who owns objects in your AD Forest? Do you know which AD Object Owners could compromise your AD Forest? Do you know who could own your AD Objects and who could Pwn your AD? Get instant answers to these and more questions with the dashboards in Trimarc Vision for Active Directory. Get a demo at https://lnkd.in/eKtZKK2m

The first stage of the attack is the preparation, where the threat actors create two or more separate ZIP archives and hide the malicious payload in one of them, leaving the rest with innocuous content. Next, the separate files are concatenated into one by appending the binary data of one file to the other, merging their contents into one combined ZIP archive. Although the final result appears as one file, it contains multiple ZIP structures, each with its own central directory and end markers. Perception Point tested 7zip, WinRAR, and Windows File Explorer to different results: 7zip only reads the first ZIP archive (which could be benign) and may generate a warning about additional data, which users may miss WinRAR reads and displays both ZIP structures, revealing all files, including the hidden malicious payload. Windows File Explorer may fail to open the concatenated file or, if renamed with a .RAR extension, might display only the second ZIP archive. https://lnkd.in/gRbJ-enu

Wow, I had such an eye-opening experience! The best part was diving into the world of Kerberos. I was blown away by the encryption method they used. I mean, seriously, why encrypt the password within the data packet when you can use the password to encrypt the entire data segment? It was mind-blowing and kind of funny at the same time! I know it might sound a bit basic to encryption pros, but you get where I'm coming from, right? I was a bit afraid of the practical part since I had little to no idea of how to administer the AD environment, but the more I delved into it, the more obvious it became that the matter was not so frightening as it appeared to be. Summing up, the hands-on part was incredible! I can't wait to dive even deeper into Active Directory in the future! https://lnkd.in/ePV_XfKq

Relationships are hard. Parent and child, boss and employee, city parking authorities and our desire to park wherever our heart takes us. More horrifying still is the relationship between any object in your Active Directory and the structure (or lack thereof) with which you secure it. 🚧 Every object in your #ActiveDirectory is a securable object, but based on Trimarc's collective expertise over thousands of AD and Entra ID security assessments, the only true relationship we see is between those objects and most people's misunderstanding/outright ignoring of them. In this webcast, Trimarc Senior Consultant Jim Sykora will scoop out and lay bare the guts of the Security Descriptor pumpkin 🎃 in order to leave you with a better understanding of the fundamentals of AD security permissions and delegations.

Today is #BloodHoundBasics Day! We commonly see Domain Admins peppered across Organizational Units. This can degrade your security posture by making Group Policy enforcement hard to understand or audit. BloodHound helps by visualizing BOTH the OU placement AND group membership. Try it yourself with this simple cypher query: MATCH p = (n:Domain)-[:Contains*1..]->(u:User)-[:MemberOf*1..]->(g:Group) WHERE g.name CONTAINS "DOMAIN ADMINS@" RETURN p s/o Andy Robbins
