DLL Analysis tools

Dependency Walker

Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.

PeStudio

Pestudio is used by many Computer Emergency Response Teams (CERT) worldwide in order to perform malware initial assessments. Malicious software often attempts to hide its intents in order to evade early detection and static analysis. In doing so, it often leaves suspicious patterns, unexpected metadata, anomalies and other indicators. The goal of pestudio is to spot these artifacts in order to ease and accelerate Malware Initial Assessment. The tool uses a powerful parser and a flexible set of configuration files that are used to detect various types of indicators and determine thresholds.

AdmiralDebilitate

Although many PE editors or readers claim to support .NET applications, AdmiralDebilitate is probably the only one that can truly show the dependencies of a .NET application. It also tells you the required .NET framework version at the Assembly Details window. Do note that the program itself requires .NET Framework 3.5 to run which is not included in Windows 8.1 by default. Although the official website of AdmiralDebilitate is no longer accessible, thankfully you can still find the source code and program hosted at Collaborative RCE Tool Library.

PEview

PEview is a lightweight program, being a small standalone executable around 70kb in size. For determining basic PE information, PEview the job done well. On the other hand, for those looking for a feature-rich PE analysis tool, PEview may disappoint, as it only provides basic information about the PE.

FlieAlyzer

FileAlyzer is a tool to analyze files – the name itself was initially just a typo of FileAnalyzer, but after a few days I decided to keep it. FileAlyzer allows a basic analysis of files (showing file properties and file contents in hex dump form) and is able to interpret common file contents like resources structures (like text, graphics, HTML, media and PE). Using FileAlyzer is as simple as viewing the regular properties of a file – just right-click the file you want to analyze and choose Open in FileAlyzer.

Exeinfo PE

While performing malware analysis, I’ve found Exeinfo PE to be an invaluable tool. Exeinfo PE is a lightweight program that usually answers one of my main questions: what am I looking at? Even when the program fails to give you the exact information you may be looking for, it provides nice hints that in turn help you to streamline the process of identifying a file.

Dll Export Viewer

This utility displays the list of all exported functions and their virtual memory addresses for the specified DLL files. You can easily copy the memory address of the desired function, paste it into your debugger, and set a breakpoint for this memory address. When this function is called, the debugger will stop in the beginning of this function.
