Automating Password Retrieval with Gopher 2 Grabber

In this tutorial, I'll delve into the world of automations and explore how to bypass security measures on a Linux box. Specifically, we'll focus on the 'Beyond Root' challenge from HackTheBox (HTB), where we'll use various tools and techniques to retrieve the administrator password.

First, let's start with RunasCs.exe, a powerful tool that allows us to bypass User Account Control (UAC) and gain a shell with administrator privileges. This will give us the necessary permissions to proceed with our automation script.

Next, I'll write a Go program that fetches the seed and encrypted blob from the box, generates the decryption key using the seed, and then decrypts the blob to reveal the password for an admin user. To accomplish this, we'll use various tools such as Napper, which provides us with two interesting coding challenges wrapped in a story of real malware and a custom LAPS alternative.

In addition to these automations, I'll also find a draft blog post on the box that discusses a new internally developed solution to replace Last Automated Password Sync (LAPS), which stores passwords in a local Elasticsearch DB. We'll use this information to gain further insight into the box's security measures.

Throughout this tutorial, we'll explore various tools and techniques such as Nmap, FFuf, Hugo, Feroxbuster, Burp Suite, Ghidra, Go, YouTube, UAC, RunasCs, Scheduled Tasks, and more. By the end of this article, you'll have a comprehensive understanding of how to automate password retrieval with Gopher 2 Grabber.

In conclusion, automating password retrieval with Gopher 2 Grabber requires a combination of technical skills and creativity. By leveraging tools such as RunasCs.exe, Napper, and Go programming language, we can bypass security measures and gain access to administrator passwords. Remember to always exercise caution when attempting these types of challenges and to follow proper ethical hacking protocols.
