Mitra is a Python CLI tool that generates weird files such as binary polyglots, near-polyglots, polymocks, parasites, and zippers across many file formats. It is aimed at security research and demonstrating risks of poorly designed file formats.

Use cases

  • generate a polyglot file that is valid as two formats at once
  • append arbitrary data to a PDF while keeping it valid
  • create a PNG/DICOM polyglot for parser testing
  • demonstrate security risks of a badly designed file format
  • extract the two payloads from a polyglot file separately
  • test whether a file parser can be tricked by overlapping bytes

When to choose

  • you are doing security research on file format parsers
  • you need to quickly generate polyglot or near-polyglot test files
  • you want to explore which format features enable format abuses
  • you need proof-of-concept files for a format design review

When to avoid

  • you need a general-purpose file format converter
  • you want production tooling that fixes checksums or validates outputs
  • you need a GUI or non-technical workflow
  • your target format is not among the supported layouts
