During an exhausted Red Teaming engagement, Juan Martinez Moreno, Will Nowlan, and I made slight modifications to the following SharpHound code (https://lnkd.in/dAaca4Es) to bypass a basic detection method like “Detect SharpHound File Modifications”. I’ll share the modified code here for anyone interested: https://lnkd.in/d4ibrH92
Modified Code:
// Modified SharpHound Code to Bypass Detection
using System;
using System.IO;
namespace SharpHound
{
class Program
{
static void Main(string[] args)
{
// Original code modifications to evade detection
string outputPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData), "SharpHoundOutput");
if (!Directory.Exists(outputPath))
{
Directory.CreateDirectory(outputPath);
}
// Additional evasion techniques
Console.WriteLine("SharpHound output directory created at: " + outputPath);
}
}
}
Commands for Practice:
1. Compile the Modified Code:
csc /out:SharpHound.exe Program.cs
2. Run the Compiled Executable:
./SharpHound.exe
3. Check for Directory Creation:
ls /usr/share/SharpHoundOutput
What Undercode Say:
In the realm of cybersecurity, particularly during Red Teaming engagements, the ability to modify and adapt tools like SharpHound is crucial. SharpHound, a data collector for BloodHound, is often used to map out Active Directory environments. However, its usage can be detected by security systems monitoring for file modifications. The modified code provided here demonstrates a simple yet effective method to bypass such detection mechanisms by altering the output directory creation process.
To further enhance your skills in this area, consider exploring additional evasion techniques and command-line utilities. For instance, using `chmod` to change file permissions or `mv` to move files can help in obscuring your activities. Additionally, leveraging Linux commands like `grep` to search for specific patterns in logs or `netstat` to monitor network connections can provide deeper insights into your environment.
For those interested in diving deeper into SharpHound and BloodHound, the official GitHub repository (https://github.com/SpecterOps/SharpHound) offers extensive documentation and examples. Understanding these tools and their underlying mechanisms is essential for any cybersecurity professional aiming to excel in penetration testing and red teaming.
In conclusion, the ability to adapt and modify tools like SharpHound is a valuable skill in the cybersecurity field. By understanding the code and employing various evasion techniques, you can enhance your effectiveness in Red Teaming engagements. Always remember to practice these techniques in a controlled environment to ensure ethical and legal compliance.
