How to write an analysis plugin

Create file and class

  • Plugin file in plaso/analysis/
  • Test file in tests/analysis/
    • Create an empty subclass of tests.analysis.test_lib.AnalysisPluginTestCase

Write minimal tests

  • Write a test that loads your plugin
  • It will fail initially, but running the test while you're developing your plugin gives you a quick way to see if your code is doing what you expect.

Develop plugin

  • Implement your subclass of AnalysisPlugin
  • You'll need to define/override:
    • NAME
    • ExamineEvent()
    • CompileReport()
  • You may also want to override:
    • URLS
    • ENABLE_IN_EXTRACTION, if your plugin is eligible to run while Plaso is extracting events.

Expand tests

  • Add additional tests that test your plugin

Register classes

  • Edit plaso/analysis/ to import your plugin in the correct alphabetical order.
