This project is a parsing library for Windows EVTX log files. Our goal was to
make a resilient parser which provides a nice interface to interact with the
events programmatically. We opted for an event representation as a map which
is perfect to represent BinXML tree like structure. As a consequence, it is very
easy to (de)serialize events with the standard Go API. We also provide the
necessary APIs to query specific values of the event.
An example is better than a long talk:

}Some utilities are packaged with this library and can be used without any dependencies.
Evtxdump can be used to print in JSON format the events of several EVTX files. The events are printed ordered by time and not by their order of appearance in the file.
Evtxdump can also be used to carve Events from raw data. It can be very convenient
to recover corrupted EVTX or to carve deleted EVTX files from disk images. We advise
you to select the option -t made to print the timestamp as integer at the
beginning of each line of the output. This can be used later on to sort the events
for timelining purposes (with sort command for instance).
Usage of evtxdump: evtxdump [OPTIONS] FILES...
-V Show version and exit
-brURL string
Kafka Broker URL
-c Carve events from file
-cID string
Kafka client ID
-cpuprofile string
write cpu profile to this file
-d Enable debug mode
-l int
Limit the number of chunks to parse (carving mode only)
-memprofile string
write memory profile to this file
-o int
Offset to start from (carving mode only)
-start value
Print logs starting from start
-stop value
Print logs before stop
-t Prints event timestamp (as int) at the beginning of line to make sorting easier
-tag string
special tag for matching purpose on remote collector
-tcp string
tcp socket address for sending output to remote site over TCP. Only for type tcp
-topic string
Kafka topic
-http string
url for sending output to remote site over HTTP. Only for type http
-type string
Type of remote log collector. "http" - JSON-over-HTTP, "tcp" - JSON-over-TCP, "kafka" - Kafka
-u Does not care about ordering the events before printing (faster for large files)
docker build -t MonaxGT/evtxdump .
docker run -it --rm -v /tmp:/app/data evtxdump /app/data/log.evtx
Evtxmon is a small command line tool used to monitor in realtime the logs as they appear in the evtx files.
Usage: evtxmon [OPTIONS] EVTX-FILE
-V Show version information
-d Enable debug messages
-f value
Event ids to filter out
-s Outputs stats about events processed
-t value
Timeout for the test
-w string
Write monitored events to output file
Some values are not parsed (because we did not have samples to test), so if you see "UnknowValue: ..." in your output, it means it is not supported. So please provide us a sample of file so that we can implement it.
