TryHackMe - Volt Typhoon challenge (medium level)

-

 




Introduction

I’m publishing today a walkthrough of the new TryHackMe room named “Volt Typhoon” where you’re supposed to investigate a suspected intrusion by the notorious APT group Volt Typhoon.


What is Volt Typhoon?


       Volt Typhoon – also known as Vanguard Panda, Brronze Silhouette, Dev-0391, UNC3236, Voltzite, and Insidious Taurus – is a state-supported Chinese cyber operation that has compromised thousands of internet-connected devices.


How does it work?


      Volt Typhoon works by exploiting vulnerabilities in small and end-of-life routers, firewalls and virtual private networks (VPNs), often using administrator credentials and stolen passwords, or taking advantage of outmoded tech that hasn’t had regular security updates – key weaknesses identified in US digital infrastructure.


      In this challenge, we need as a security analyst investigate the intrusion realized by Volt Typhoon by retracing their steps over various log types from a two-week time frame during which the suspected attack occurred with Splunk.







Execution part :     


       In the Execution part, we’re told the following information : “Volt Typhoon is known to exploit Windows Management Instrumentation Command-line (WMIC) for a range of execution techniques.

       In the second question from this part we know that they’re using “ntdsutil” tool that is a “command-line tool that provides management facilities for Active Directory Domain Services (AD DS) and Active Directory Lightweight Directory Services (AD LDS).”



Defense Evasion:

      In the third question you can look also for the term "“HKEY” will be more easy.





I hope you enjoy with this challange !!

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 ...

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...

        Dive into the heat of a live phishing attack as it unfolds within the corporate network. In this high-pressure scenario, your role is to meticulously analyze and document each phase of the breach as it happens. First I let all the alert to come to correlate them together. You start from the CRITICAL ones (0 alert) - HIGH - MEDIUM - LOW. I check all dns alert , all of them was false positive , nothing suspicious . On the Process ones you must to check on splunk , search on google if you don't know the specific process . I make one mistake , with the attashments invoice.pdf.ink , apparently it was true positive , but I check the SHA-256 on VirusTotal , nothing suspicious..  I realy enjoy with this SIM , Have Fun !!
