About This Tool

The ELF Viewer provides static analysis of ELF binaries by parsing core structures such as the ELF header, program header table, and section header table. It determines architecture (32- vs 64-bit), endianness, entry point, interpreter path, and basic metadata. This supports quick validation of artifacts, compatibility checks, and asset inventory in development and security workflows. The tool outputs a structured data model suitable for automation and a human-readable summary for rapid triage. It is designed to integrate into CI pipelines, incident response playbooks, and asset management processes where non-executable inspection is required.
Core logic adheres to the ELF specification, with optional deep-dive capabilities such as symbol table extraction, dynamic section parsing, and NX/PIE status detection. It preserves safety by performing only static analysis and returning deterministic results across multiple toolchains. The unique value lies in providing a single source of truth for binary metadata, enabling reproducible checks across environments and teams, and supporting automation-friendly formats for downstream tooling. Use cases include pre-release artifact verification, dependency auditing, and quick investigations of unknown binaries found in repositories or build artifacts.

How to Use

  1. Upload the ELF binary file to the tool via the file input.
  2. Optionally select analysis_level (basic or full) to control depth of data extraction.
  3. Run or wait for automatic analysis to complete; results are produced as structured data and a summary.
  4. Review the metadata: architecture, entry point, sections, and, if available, symbol tables and dynamic links.
  5. Export results as JSON for automation or log the summary for manual review.

Frequently Asked Questions

Find Quick Answers

What formats are supported?
The tool supports ELF binaries (32-bit and 64-bit) for Linux and compatible platforms. It validates the magic header and class before parsing. Non-ELF formats or heavily obfuscated/encrypted binaries may be rejected or only partially analyzed with explicit indicators.
What outputs are produced?
Primary outputs include a structured data summary with architecture, bitness, endianness, entry point, sections, and program headers. If available, symbol tables and dynamic entries are included. All results are machine-readable JSON and also presented in a human-readable form for quick review.
Is it safe to use in CI or security workflows?
Yes. The tool performs static analysis only and does not execute binaries. It is non-destructive and designed to be safe for integration into CI pipelines, artifact scans, and incident response workflows. Use containerized environments to further isolate the analysis.
