My friend Lars and I were just talking about some of the research areas we are working on and randomly the conversation turned into “what shall we call it?” and then LDAPNomNom came up! So I whilst laughing (coz the name is lulz) with my buddy I downloaded and ran LDAPNomNom against a lab vm quickly! (Lars also fixed an error with readme.md that I pointed out coz my debug skillz ROCK! š )
So here we have me doing username enumeration via LDAP Ping using LDAPNOMNOM!

This post started as a reply to a great topic on LinkedIn, but I hit the character limit so now it’s a blog post!
Years ago I simulated attacks (authorized obviously for the people that have wild imaginations) on a customer which included a physical attack where I walked into a healthcare organization, armed with a suit a smile (and a USB key) I needed to gain access and attempt to move laterally and escalate privileges.

Ok you need to do some AD Security Auditing or Security Testing/Exploitation, great. Letās look at some of the common misconfigurations and some tools to help you, a list of things will obviously not be the answer, you will need a method and process to go through from recon/enumeration through to exploitation and impact (effects), but that’s what google is for (and CTFs/Labs)! This post is just me jotting down some notes, hopefully they help defenders think about improving their posture.

Whilst the common person will largely link the words “hacker/hackers” to criminal the reality is hackers are scientists/artists/creators/ComputerOperators and the choice of being a criminal or not is down to actions and consequences. So the debate about if you identify as “hacker” does that make you a criminal, well it’s nonsense isn’t it.

Cyberwarfare in Ukraine was hyped as a MASSIVE thing, yet largely it’s been more bark and bite, but perhaps people need to understand that you can’t just “CYBER” a remote network, and even if you could, let’s say you get RCE on 30 networks in a country, so what? There needs to be value, purpose and something that will support other objectives, this isn’t a CTF.

I was pottering about (not like a wizard, more like a cold infected zombie!) and an email hit my mailbox with the āHead of Cyber Architectureā at BA. I have no intention of applying but I thought.. I wonder if this is a good exercise to show people how I would go about the exercise? Well to even begin this I need to write down some notes. So I guess here we goā¦ how far I get into this āfantast footballā style scenario who knows, but hopefully it will show some people how I might do things! First up letās look at the raw requirement:
