Introduction

QDoctor, developed by QAX-Anti-Virus, is a non-traditional Anti-Rootkit (ARK) tool designed for comprehensive emergency response on Windows systems. It integrates traditional ARK functionalities with common incident response requirements, significantly enhancing the efficiency of identifying and locating potential malicious items. QDoctor's robust log export and import features allow users to extract detailed system information, enabling professionals to quickly diagnose system anomalies and even build automated threat analysis systems.

Installation

QDoctor is available as a single executable file, supporting both X86 and X86_64 systems. You can download the latest version directly from its GitHub releases page: https://github.com/QAX-Anti-Virus/QDoctor/releases/download/latest/QDoctor.exe

Supported Systems:

  • Windows 7, 8, 8.1, 10, 11 (x86/x64)
  • Windows Server 2008 R2, 2012, 2012 R2, 2016, 2019, 2022 (x64)

Important Notes:

  • Due to the nature of ARK tools, there is a risk of system crashes. Always save your data before use.
  • For Windows 7 and 8, you may need to install SHA-2 signature patches or disable driver signature verification.
  • The tool might be flagged by security software, including QAX's own products. Please verify the signature and add it to your whitelist if necessary.
  • Memory integrity verification (kernel isolation) can cause driver loading failures. If this occurs, disable the feature and restart your system.

Examples

QDoctor offers a user-friendly interface with powerful diagnostic capabilities. Here are some of its key features and functionalities:

Special Features:

  • One-click Structured Data Export: Export comprehensive structured data from all tabs, including file hash values, for easy analysis.
  • Data Import: Seamlessly import data exported from other machines, facilitating remote troubleshooting and analysis.
  • Adversarial Sample Penetration: Possesses the ability to penetrate some adversarial samples, providing deeper insights.

Core Functionalities:

  • Basic System Information: View MAC address, system version, and other fundamental details.
  • Autostart Items: Inspect common registry startup entries, scheduled tasks, services, drivers, and WMI entries.
  • Process Management: Monitor processes, threads, modules, memory, handles, and kernel callbacks. Perform actions like pausing, terminating, unloading modules, or closing handles. Includes signature verification and Hook scanning.
  • Kernel Analysis: Explore driver modules, unloaded modules, system callback functions, micro-filter drivers, NDIS callbacks, SSDT/ShadowSSDT tables, DPC timers, FSD drivers, object information, kernel work queues, and device stacks.
  • Network Monitoring: View network connections for all processes, supporting IPv4 and IPv6 TCP/UDP connections.
  • System Patches & Software List: Review installed system patches and a list of installed software, similar to "Add/Remove Programs."
  • System Logs: Access application, security, setup, and system event logs.
  • File System: A simple file manager to browse system drives and perform forced file deletions.

QDoctor's ability to export structured data is a significant advantage. This feature allows users with threat intelligence resources to build automated threat analysis systems, enabling rapid detection of threats by uploading the exported compressed logs.

Why Use

QDoctor is an indispensable tool for cybersecurity professionals and enthusiasts engaged in Windows system security and incident response. Its unique blend of traditional ARK capabilities, advanced diagnostic features, and structured data export makes it highly effective for quickly identifying system anomalies, detecting sophisticated malware, and streamlining the entire threat analysis process. It empowers users to gain deep insights into their system's state, making it a valuable asset for maintaining system integrity and responding to security incidents.
