For example, the following command starts the calculator via node.js:Įcho require('child_process').exec("calc.exe") | "%ProgramFiles(x86)%\NVIDIA Corporation\NvNode\NVIDIA Web Helper.exe" -iįrom attacker perspective, this opens two possibilities. It can be started in interactive mode which means that scripts can be passed via pipe (payloads are not written to disk).

Nearly similar PowerShell advantages can be achieved by abusing node.js from NVIDIA if the target system has these drivers installed. However, it’s the first binary which gets removed from the whitelist by administrators, PowerShell v5 provides very good logging (attack detection and forensic), Device Guard UMCI (user mode code integrity) places PowerShell in Constrained Language mode and Antivirus solutions monitor malicious invocations of PowerShell.
Nowadays, the most common technique to bypass application whitelisting is to start PowerShell, because the target code can be passed inside arguments, it has full access to the Windows API, it is a signed binary from Microsoft and it can be found on all newer systems. Since this file is already on the system and it has a valid signature, it will be whitelisted by the application whitelisting solution. That means we can find node.js on systems with NVIDIA drivers installed. This is a renamed version of node.js (but signed by NVIDIA Corporation) which can be verified via the meta data of the file: %ProgramFiles(x86)\%NVIDIA Corporation\NvNode\NVIDIA Web Helper.exe The following executable gets installed by NVIDIA: ĭuring a quick research in a different area, I came across a system which had NVIDIA drivers installed. Other good and recommended sources of known bypass techniques and hardening guides are blog posts from Casey Smith (subtee), Matt Nelson (enigma0x3) and Matt Graeber (mattifestation). Knowing these bypass techniques is really important for administrators who maintain such protected environments because special rules must be applied to prevent these attacks. SEC Consult Vulnerability Lab is doing research in this area since several years, bypass techniques were already presented in 20 at conferences such as CanSecWest, DeepSec, Hacktivity, BSides Vienna and IT-SeCX, see. This can be achieved on Microsoft Windows 10 or Server 2016 with Microsoft Device Guard. Another concept is to enforce code and script integrity via signatures.

How to properly Install Nvidia Drivers on High Sierra 10.13 (17A405) If pairing a Nvidia Graphics card with High Sierra follow this alternative guide: The steps below will guide you through the process of getting your Nvidia hackintosh working: If you are using a 7/9/10 series Nvidia card you will need the web drivers. If you are using an old graphics card like a GTX 650 / 660 / 670 / 680 you will not need Web Drivers as there is native support baked in from once upon a time Apple was using Nvidia cards in their Mac’s. If you are using the latest Pascal Graphic Cards i.e.
You will need to download the version that matches the version of macOS you are using.
