PowerShellArsenal
A PowerShell module for reverse engineering that disassembles code, analyzes malware, parses memory structures, and inspects Windows internals.
What is PowerShellArsenal?
PowerShellArsenal is a comprehensive PowerShell module designed to assist reverse engineers in analyzing software, particularly malware and system internals. It provides a suite of tools for disassembling both managed and unmanaged code, performing memory analysis, parsing file formats, and extracting low-level Windows OS information.
Reverse engineers and security analysts focusing on malware analysis, Windows internals, and binary forensics, especially those working in PowerShell environments.
Developers choose PowerShellArsenal for its extensive, integrated toolset that combines disassembly, memory inspection, and file parsing into a single PowerShell module with v2 compatibility and clean, object-oriented output, avoiding reliance on external command-line utilities.
Overview
A PowerShell Module Dedicated to Reverse Engineering
Use Cases
Best For
- Disassembling native and managed code using the Capstone Engine and IL disassembly tools.
- Analyzing .NET malware by extracting strings, resources, and manipulating assemblies.
- Inspecting and scraping process memory to extract strings and query virtual memory information.
- Parsing PE files, LIB symbols, and object files both on-disk and in-memory.
- Querying low-level Windows OS information like system details and process environment blocks.
- Performing binary analysis tasks such as entropy calculation and string extraction from files.
Not Ideal For
- Environments where PowerShell is unavailable or disfavored, such as Linux or macOS systems
- Teams requiring graphical user interfaces for interactive malware analysis
- Projects focused on non-Windows binaries or cross-platform reverse engineering
- Real-time, continuous monitoring of system activity or malware behavior
Pros & Cons
Pros
Integrates disassembly, memory analysis, and file parsing into a single PowerShell module, reducing reliance on external utilities like Sysinternals strings.exe, as shown in the Misc and Parsers sections.
Ensures backward compatibility with older Windows systems, a key philosophy mentioned in the README, making it accessible in legacy environments.
Emphasizes outputting custom objects instead of Write-Host, per the style guide, facilitating pipeline integration and data manipulation in PowerShell scripts.
Each tool can run individually, enhancing flexibility, and the module is easy to install in standard PowerShell paths, as detailed in the Usage section.
Cons
Heavily relies on Windows internals and APIs, such as kernel32 and ntdll calls, making it unsuitable for analyzing non-Windows software or operating in cross-platform setups.
Lacks GUI support, which can be a drawback for analysts preferring visual tools like IDA Pro or x64dbg for interactive debugging and exploration.
Requires manual module installation, unblocking files for internet downloads, and familiarity with PowerShell, which can be cumbersome for newcomers or in restricted IT environments.
