TryHackMe - Disk Filtration challenge

-






     Someone decided corporate secrets are a free-for-all and our dear Liam thought he could play sneak-and-leak. This writeup walks through the hunt: the breadcrumbs on the endpoint, the USB that betrayed him, the dusty hotspot he used to dodge network logs, and the little executable the external actor insisted he run. Read it like a detective novel, but with more registry keys and less melodrama. Screenshots are left exactly where you asked — because evidence should always stare you in the face.


Scenario

Tech THM discovered their critical data had been leaked to the competitors. After an internal investigation, the company suspects Liam, a recently terminated employee who was working as a system engineer with Tech THM. This suspicion was raised as Liam had access to the leaked data in his company-provided workstation. He often worked late hours without clear justification for his extended presence. He was also caught roaming around the critical server room and taking pictures of the entry gate. Following these suspicions, Liam’s workstation (provided by the company) was investigated. The initial investigation suggests that an external entity was also helping Liam.

TryHackMe - Typo Snare Threat Hunter Simulator (medium level)

  Threat Hunt Walkthrough The "Typo Snare" scenario on TryHackMe is a fantastic real-world simulation of a sophisticated, multi-stage attack. It starts with a simple mistake and escalates to a full domain compromise, culminating in ransomware. This post will walk you through the entire attack chain, phase by phase, showing you how to find each piece of evidence using Elastic KQL queries. Phase 1: Initial Access & Execution What Happened: The attack began when the user perry.parsons on workstation WKSTN-03 needed a 7-Zip tool. He googled it, clicked a typosquatted link ( 7zipp.org ), and downloaded a trojanized installer. This installer executed a PowerShell script ( 7z.ps1 ) directly from the attacker's server to establish the initial foothold. How to Find It: You are looking for a PowerShell process that was likely spawned by a browser and contains a command to download and execute a script ( iwr for Invoke-WebRequest and iex for Invoke-Expression ). KQL Query...

TryHackMe - Threat Hunting Simulator - Health Hazard

  Scenario overview After months of juggling content calendars and caffeine-fueled brainstorming, co-founder Tom Whiskers finally carved out time to build the company’s first website. It was supposed to be simple: follow a tutorial, install a few packages, and bring the brand to life with lightweight JavaScript magic.   But between sleepless nights and copy-pasted code, Tom started feeling off. Not sick exactly, just off. The terminal scrolled with reassuring green text, the site loaded fine, and everything looked normal.   Then, a strange file appeared on the system. No one could say where it came from. It wasn’t part of the tutorial, didn’t match any known dependencies, and didn’t even run.   It just waited.   Scenario objectives Determine how a threat actor first gained a foothold on the system. Identify suspicious activity that may point to the initial compromise method. Investigate signs of malicious execution following the initial access. Analyse the logs ...

TryHackmMe Side Quest AOC 2025 - Scheme Catcher (Insane Level)

  Second Side Quest (Scheme Catcher) started with discovering the key in the Advent of Cyber Day 9 room and using it to remove the firewall on the target machine. Afterwards, fuzzing a web application on the target for directories we were able to discover a file with a binary inside and analyzing the binary we discovered another endpoint. Checking out this endpoint we discovered the application running on another port and reverse enginering it we discovered a Use-After-Free vulnerability and with a heap exploitation exploit we were able to get remote code execution and a shell inside a container. Inside the container we discovered a SSH key which we used to get a shell on the host and reverse engineering and exploiting a vulnerable kernel module we were able to escalate to root and complete the room. Python Script : #!/usr/bin/env python3 from pwn import * import io_file context . update ( arch = " amd64 " , os = " linux " , log_level = " error "...
