How to use Detect-It-Easy: identify and inspect executable files

Updated · written with AI from the project's own documentation and checked against our catalogue data

Detect-It-Easy (DiE) is a cross-platform tool for file identification and static inspection. It examines a file without running it and reports what the file is, such as its compiler, packer or protector. This guide covers where to get it safely, what it is suited for, and how to read its analysis of an unknown binary.

Quick start

  1. 1Get DiE from an official source. Download a release or beta build from the official DIE-engine releases page linked in the README, not from detectiteasy.com.
  2. 2Choose your platform. DiE is listed for Windows, Linux and MacOS. Pick the build that matches your system.
  3. 3Clone the repository if you want source. Run git clone https://github.com/horsicq/Detect-It-Easy to get the source code.
  4. 4Open the file to analyse. Load the unknown executable into DiE. The file is inspected statically and is never launched.
  5. 5Review the identification. Read the reported compiler, packer or protector and note which results are signatures and which are heuristic findings.
  6. 6Verify important findings. Check key results against another tool before acting on them.

What Detect-It-Easy does and who it is for

DiE reads executable formats and uses signature databases and heuristic checks to report what a file is. Because the analysis is static, the file is never launched. The README describes it as used by malware analysts, cybersecurity experts and reverse engineers.

It is a good fit for triaging unknown Windows executables, checking whether a binary is packed or protected, and file type identification in digital forensics. It is not meant for opening or converting ordinary documents, and it is not a sandbox for running suspicious files.

  • Malware analysts triaging unknown Windows executables
  • Reverse engineers checking whether a binary is packed or protected
  • Digital forensics work that needs file type identification
  • Developers who want to script checks through the DiE API library

Download Detect-It-Easy from an official source

Use the release links in the official project repository. The README warns that detectiteasy.com is not affiliated with the project and should not be used to download DiE.

The README lists a download page for release and beta builds, and a separate DiE API Library for developers. The project lists no prerequisites.

  • Download release or beta builds from the official DIE-engine releases page linked in the README
  • Developers can use the die_library repository for the DiE API Library
  • Do not download DiE from detectiteasy.com

Get the source code with git

If you prefer to work from source, the README gives a single clone command for the main repository.

git clone https://github.com/horsicq/Detect-It-Easy

Analyse a file and read the results

Open a file in DiE and review the identification it reports. With heuristic scanning enabled, the PE heuristic engine runs as a separate analysis layer that can corroborate, qualify or reject database results, and it marks each heuristic conclusion visibly so you can tell it apart from signature matches.

Treat findings as evidence to verify, not as a verdict. The README notes that heuristic checks are designed to control false positives, but the output assumes some familiarity with executable structure.

  • Check packer and protector reports, which can come from signatures or heuristics
  • Look at the evidence behind each heuristic finding before drawing conclusions
  • Compare results with other tools when a finding matters

Understand what the heuristic checks look for

The PE heuristic engine covers headers, sections, imports, exports, resources, .NET metadata, overlays and reachable startup code. Its passes include code and protection checks, native and .NET anti-analysis probes, native anomaly checks and packer or protector detection.

The engine reports these as passes and evidence, not as a complete list of every check it performs.

  • Packers, cryptors, SFX archives and high entropy
  • Anti-debugging and anti-analysis probes
  • Obfuscation in .NET assemblies
  • Licensing and DRM clues in .NET code

What people use it for

  • Triaging an unknown Windows executable to see whether it is packed
  • Confirming the compiler or toolchain that produced a binary
  • Checking a suspicious .NET assembly for obfuscation
  • Adding automated file identification to a workflow through the DiE API library

Frequently asked questions

Is Detect-It-Easy free?

The source does not state a price, but the project is published under the MIT licence, which you can check in the repository. A donation link is also provided in the README.

What is Detect-It-Easy used for?

It identifies what a file is, such as its compiler, packer or protector, using static inspection. Malware analysts, security experts and reverse engineers use it to understand unknown binaries.

Does Detect-It-Easy run the file?

No. The README says the file is never launched. Analysis works from headers, sections, imports, resources and similar structures.

Which operating systems does Detect-It-Easy support?

The README lists Windows, Linux and MacOS.

Is Detect-It-Easy safe to download?

Download only from the release links in the official repository. The README warns that detectiteasy.com is not affiliated with the project.

What are alternatives to Detect-It-Easy?

Comparable projects include PEiD, Exeinfo PE, CFF Explorer and Ghidra. Ghidra is a broader reverse engineering framework, while the others focus on PE file inspection.

Our verdict

Detect-It-Easy suits malware analysts, reverse engineers and forensic examiners who need to identify packed or protected executables without running them. It is less suitable for beginners without binary format knowledge, for ordinary document work, or for anyone who needs a sandbox to execute suspicious files.
