The hidden threat lurking in your Windows machine

Modern Windows environments are a battlefield of sophisticated malware that can hide deep inside the kernel, hijack system callbacks, or masquerade as legitimate processes. Traditional antivirus products often miss these stealthy components, leaving analysts and developers scrambling for a reliable way to expose, dissect, and neutralize them.

Enter OpenArk – an open‑source, single‑executable anti‑rootkit framework that gives you direct visibility into the OS kernel, processes, memory, drivers, and more. Whether you’re a reverse‑engineer hunting a persistent threat, a developer needing a low‑level debugging aid, or a security team looking for a cost‑free, auditable tool, OpenArk puts powerful investigative capabilities at your fingertips without vendor lock‑in.

Why Choose OpenArk?

• Zero‑dependency, one‑click binary – A single OpenArk.exe works on 32‑ and 64‑bit Windows (XP through 11) without installing runtimes or libraries.
• Full source transparency – All kernel and user‑mode modules are open on GitHub, enabling security audits, custom extensions, and community‑driven improvements.
• Comprehensive kernel toolkit – Access to driver/object memory, callbacks, IDT/SDT, NDIS/WFP filters, and hotkey management that would otherwise require a custom driver.
• Rich user‑mode utilities – Process/thread/module inspection, DLL injection, memory scanning, token manipulation, and a built‑in console for ad‑hoc commands.
• Extensible “CoderKit” & “Bundler” – Parse PE/ELF files, bundle directories into a standalone executable, and script repetitive tasks—all from the same UI.
• Cost‑free and vendor‑agnostic – No licensing fees, no telemetry, and no hidden backdoors. You keep full control of your investigative workflow.

Spotlight on Key Features

Getting Started

1. Download the binary

OpenArk ships as a single executable. Grab the latest release from the GitHub releases page or the official website.

# Example using PowerShell to download the latest release (replace URL with actual asset link)
Invoke-WebRequest -Uri "https://github.com/BlackINT3/OpenArk/releases/latest/download/OpenArk.exe" -OutFile "OpenArk.exe"

2. Run with Administrator privileges

Many kernel‑level features require elevated rights. Right‑click OpenArk.exe → Run as administrator.

3. Explore the built‑in console

When the UI launches, press Ctrl+~ to open the console. Try a few starter commands:

# List all processes with PID, name, and token info
ps

# Dump memory of a specific process (replace 1234 with the PID)
memdump -p 1234 -o dump.bin

# Inject a DLL into a process
inject -p 1234 -d C:\path\to\my.dll

4. Build from source (optional)

If you want to extend OpenArk or compile a custom kernel driver, follow these steps:

git clone https://github.com/BlackINT3/OpenArk.git
cd OpenArk

# Open the solution in Visual Studio 2022 (requires the Windows Driver Kit)
# Build the `UNONE` (user‑mode) and `KNONE` (kernel‑mode) projects

Tip: The repository includes a Manuals folder with detailed build instructions and API references. See the full documentation at https://openark.blackint3.com/manuals/.

Comparison with Proprietary Alternatives

OpenArk delivers comparable (and often deeper) kernel visibility without the licensing fees, telemetry concerns, or vendor lock‑in that come with commercial products.
