evtx2es 1.3.1

Fast import of Windows EventLogs(.evtx) into Elasticsearch.

Evtx2es

Fast import of Windows EventLogs(.evtx) into Elasticsearch.

Life is too short and there is not enough time to process huge Windows EventLogs with pure-Python software.
evtx2es uses Rust library pyevtx-rs, so it runs much faster than traditional software.

Usage

When using from the commandline interface:

$ evtx2es /path/to/your/file.evtx

When using from the python-script:

from evtx2es import evtx2es

if __name__ == '__main__':
  filepath = '/path/to/your/file.evtx'
  evtx2es(filepath)

Arguments

evtx2es supports importing from multiple files.

$ evtx2es file1.evtx file2.evtx file3.evtx

Also, possible to import recursively from a specific directory.

$ tree .
evtxfiles/
  ├── file1.evtx
  ├── file2.evtx
  ├── file3.evtx
  └── subdirectory/
    ├── file4.evtx
    └── subsubdirectory/
      ├── file5.evtx
      └── file6.evtx

$ evtx2es /evtxfiles/ # The Path is recursively expanded to file1~6.evtx.

Options

--host:
  ElasticSearch host address
  (default: localhost)

--port:
  ElasticSearch port number
  (default: 9200)

--index:
  Index name of Import destination
  (default: evtx2es)

--size:
  Number of grouped documents during bulk insertion (Normally, It doesn't need to change this option.)
  (default: 500)

--scheme:
  Scheme to use (http, or https)
  (default: http)

--login:
  The login to use if Elastic Security is enable
  (default: )

--pwd:
  The password linked to the login provided
  (default: )

Examples

When using from the commandline interface:

$ evtx2es /path/to/your/file.evtx --host=localhost --port=9200 --index=foobar --size=500

When using from the python-script:

if __name__ == '__main__':
    evtx2es('/path/to/your/file.evtx', host=localhost, port=9200, index='foobar', size=500)

With the Amazon Elasticsearch Serivce (ES):

$ evtx2es /path/to/your/file.evtx --host=example.us-east-1.es.amazonaws.com --port=443 --scheme=https --index=foobar

With credentials for Elastic Security:

$ evtx2es /path/to/your/file.evtx --host=localhost --port=9200 --index=foobar --login=elastic --pwd=******

Note: The current version does not verify the certificate.

Appendix

Evtx2json

Extra feature. :sushi: :sushi: :sushi:

Convert from Windows Eventlog to json file.

$ evtx2json /path/to/your/file.evtx /path/to/output/target.json

Convert from Windows Eventlog to Python List[dict] object.

from evtx2es import evtx2json

if __name__ == '__main__':
  filepath = '/path/to/your/file.evtx'
  result: List[dict] = evtx2json(filepath)

Output Format Example

Using the sample evtx file of JPCERT/CC:LogonTracer as an example.
