So this CTF is categorized as easy, but I would actually say that getting foothold was pretty hard. Once inside, its pretty straight forward enumeration and lateral movement if you’ve done enough information gathering. Anyway, as always I like to start with an nmap scan to see what we’re working with. # Nmap 7.92 scan…

https://www.tryhackme.com/room/attacktivedirectory This CTF is more “guided and less challenge based”. Its one of the more interesting Windows rooms I’ve tried on THM. Enumeration We start with NMAP scan. # Nmap 7.60 scan initiated Fri Aug 6 12:08:59 2021 as: nmap -sC -sV -oN nmap.result 10.10.195.136 Nmap scan report for ip-10-10-195-136.eu-west-1.compute.internal (10.10.195.136) Host is up (0.00046s…

This is an interesting CTF where, based on the name of this machine, I’ll have to analyze a pcap file and try to get some information out of it. So as always, I start with the enumeration stage. Enumeration From the NMAP scan I see that port 21, 22 and 80 are open. Lets check…
Enumeration In the enumeration stage I start off by doing an NMAP scan. There are a couple of interesting ports open, among other things port 445 (SMB) and 1433 (mssql). I’ll run ‘enum4linux’ against the server. The interesting take from that scan was that it dosent require username or password to connect to SMB. We’ll…
