Extract logs based off events from sysmon. Comes as a package, cli and ui.

Sysmon Extract

Sysmon Extract is a library to extract events from the sysmon log type based off the event id. They can be extracted as a file (any big data format) with support for HDFS or in memory as a Spark or Pandas DataFrame. As a note, this library works best with Spark as it leverages it for the ETL process.

The library comes with a library, cli and UI.

sysxtract -i /media/sidhu/Seagate/empire_apt3_2019-05-14223117.json -e 1 -e 2 -lc log_name -ec event_data -s -a host.name -o /home/sidhu/output.json

Let's break it down.

Input file: -i /media/sidhu/Seagate/empire_apt3_2019-05-14223117.json

Sysmon Events to extract: -e 1 -e 2

Column in the dataset that describes the log source (Sysmon, Microsoft Security, Microsoft Audit, etc.): -lc log_name

Column in the dataset that contains the nested sysmon data (often event_data): -ec event_data

Output as a single file: -s

Additional columns to extract: -a host.name

Output file name: /home/sidhu/output.json

UI

sysextract -ui

Package

Using the example above:

from sysxtract import extract

# Extract to a file
extract(
    "/media/sidhu/Seagate/empire_apt3_2019-05-14223117.json",
    [1, 2],

    event_column="event_data",
    additional_columns="host.name",
    single_file=True,
    output_file="/home/sidhu/output.json"
)

# Extract to a file using an existing Spark cluster

    additional_columns="host.name",
    single_file=True,
    output_file="/home/sidhu/output.json",
    master="spark://HOST:PORT" # mesos://HOST:PORT for yarn/mesos cluster

    single_file=True,
    output_file="/home/sidhu/output.json",
    spark_sess=spark, # spark session variable, usually named spark
)

# NOTE: Must provide an existing Spark Session
extract(
    "/media/sidhu/Seagate/empire_apt3_2019-05-14223117.json",
    [1, 2],
    log_column="log_name",

    additional_columns="host.name",
    single_file=True,
    spark_sess=spark, # spark session variable, usually named spark
    as_spark_frame=True
)

# Extract to a Pandas DataFrame
df = extract(
    "/media/sidhu/Seagate/empire_apt3_2019-05-14223117.json",
    [1, 2],
    log_column="log_name",

# Extract using SparkDf as input
# NOTE: Must provide an existing Spark Session
df = extract(
    spark_df,
    [1, 2],
    log_column="log_name",
    event_column="event_data",
    additional_columns="host.name",
    single_file=True,
    as_pandas_frame=True
)

# Extract using PandasDf as input
# NOTE: To use a Pandas DataFrame as input and a Spark DataFrame as output, a Spark Session must be provided.
df = extract(
    pandas_df,
    [1, 2],
    log_column="log_name",
    event_column="event_data",
    additional_columns="host.name",
    single_file=True,
    as_pandas_frame=True
)

Installation

pip install sysxtract

Since this library leverages Spark, specifically PySpark, you need to install it manually. This allows for version compatability when connecting to existing clusters.

pip install pyspark==$VERSION.

If you're going to use spark locally:

pip install pyspark
