HackTheBox – Precious Write-up

Hi everyone! This article is on a Linux easy machine that requires enumerating the downloaded metadata of the PDF file from tbe website for foothold, enumerating directories for password to another user, and finally exploiting sudo privilege misconfiguration and Yaml.load Ruby deserialization for privilege escalation. Let’s get started! 1. Nmap $ IP=10.10.11.189 $ sudo nmap […]

South Korea Trip 2023

Hi everyone! Recently I went to South Korea and it was my first time going to South Korea. It was a really short trip as we only went there for 4 days 3 nights. The 4th day was practically nothing as our plane departed at 1pm. Thus, we had to rush to the airport after […]

HackTheBox – Photobomb Write-up

Hi everyone! This write-up is on an easy Linux machine which focused on enumerating the webpage source for backdoor access to login to a webpage, using command injection vulnerability for initial access, and path hijacking via sudo for root privilege. Let’s get started! 1. Nmap enumeration $ IP=10.10.11.182 $ sudo nmap -sC -sV -p- $IP […]

Flare-On 9 Write-up

Hi there! This year is my first time taking part in Flare-On CTF. This year’s Flare-On was held from 1st October 2022 to 12th November 2022. There are a total of 11 challenges in this year’s Flare-On. Do download and reverse engineer the binary as my write-up doesn’t include screenshots the whole reverse engineering process. […]

HackTheBox – Trick Write-up

Hi everyone! This is a Linux machine where the initial access is very CTF-like thus is not to my liking. However, I like the privilege escalation method as it is not very common. The initial access requires us to enumerate DNS such as zone transfer to reveal the subdomain name. There are plenty of rabbit […]

HackTheBox – Support Write-up

Hi everyone! This machine is an Active Directory machine where we have to enumerate SMB shared folder, use dnSpy to reverse engineer a .NET binary for LDAP credentials, LDAP query to find another user’s credentials, initial access via winrm, and privilege escalate using Kerberos Resource-based Constrained Delegation. Let’s get started! Nmap enumeration $ IP=10.10.11.174 $ […]

HackTheBox – Timelapse Write-up

Hi everyone! This is a Windows machine that only test Active Directory related content during privilege escalation. For initial access, we have to enumerate SMB for a password protected ZIP file which stores a password protected PFX file. Cracking using zip2john and crackpkcs12 was done before generating a public and private key using the PFX […]

HackTheBox – RedPanda

Hi everyone! This is a Linux machine that requires exploiting SSTI in a Java SpringFramework application via a search bar on the webpage for RCE and then initial access. For privilege escalation, we will need to emulate what group the user is in, discover a log file he/she has access to, use pspy to discover […]
