+# You can configure several matchers. They should look like this:
+#
+# matcher_name:
+#     event_field_name: sha256_hash
+#     bq_project: 'project_name'
+#     bq_query: 'SELECT DISTINCT hash FROM project.dataset.tablename WHERE hash IN UNNEST(@sha256_hash)'
+#     tags: ['bigquery-sha256-match']
+#     emojis: ['SKULL']
+#
+# The fields are used as follows:
+#     * matcher_name: Name for the matcher entry.
+#     * event_field_name: Field name in a Timesketch event that you want to match against.
+#     * bq_project: Google Cloud Project you want to run the BigQuery job under.
+#     * bq_query: Query that is used to match Timesketch events. Results from this query 
+#       will be tagged. Match the "IN UNNEST(@sha256_hash)" part to your event_field_name.
+#       This example would tag any Timesketch events which have a "sha256_hash" field that
+#       has a matching row in BigQuery in the "hash" column.
+#     * tags: Tags to apply for matching Timesketch events.

+# Config file for analyzing data to detect whether data sources
+# are present in the data set or not.
+#
+# Each analyzer definition in this file defines sets of requirements
+# that are needed to determine if a certain type of data is present
+# in the sketch. In addition to the parameters given in this definition
+# start and end time are defined as parameters to the data analyzer
+# to further limit the data set that is searched.
+#
+# The analyzer is simple, it runs the query, which is defined either as a
+# query_string or a query_dsl. Then a particular field or an attribute
+# of the resulting data set is fetched and compared against a regular
+# expression. If there is a match in the regular expression then a True
+# value is returned, and that data is considered to be part of the
+# overall dataset for that time period, otherwise False is returned and
+# we assume that data is missing from the total dataset.
+#
+# These are the available fields:
+#       description         Simple string that provides a bit more description
+#                           of the data that is being analyzed.
+#
+#       notes               A message that may be displayed to the user if the
+#                           data source is not present in the dataset, perhaps
+#                           helpful hints on where the data is defined, how to
+#                           collect it, or how to add it to Timesketch.
+#
+#       query_string        A query string (OpenSearch Query String) that
+#                           defines the search string that will be used to find
+#                           data within the dataset. This is the same search
+#                           string as can be found in the Web UI of Timesketch.
+#
+#       query_dsl           A query DSL (OpenSearch Query DSL) that defines the
+#                           full query DSL that is used to find data within the
+#                           the dataset. Each data analyzer needs to define
+#                           either a query_string or a query_dsl. If both are
+#                           defined the query_string is used and query_dsl
+#                           is ignored.
+#
+#       attribute           The attribute or field that will be further
+#                           inspected by a regular expression in order to
+#                           determine if the data exists within the dataset.
+#
+#       regular_expression  The regular expression that is run on the data from
+#                           the field or the attribute that is fetched from the
+#                           the attribute definition.
+#
+#       re_flags            Each regular expression can define a flag, which is
+#                           a list of flags as strings from the re module.
+#                           These include:

+  Remote Desktop Protocol (RDP) is a protocol developed by Microsoft which provides a user with a graphical

+description: |
+  PsExec is a command-line tool that allows you to execute commands on remote computers.
+  It is part of the Sysinternals suite of tools, which are a collection of free and
+  open-source utilities for Windows system administration.
+
+  It works by establishing a remote connection to the target computer and then executing
+  the specified command. The command can be anything that you would normally run on a local
+  computer, such as a batch file, a PowerShell script, or a simple command-line instruction.
+
+  PsExec can be used to move from one computer to another on a network. This can be

+display_name: Windows Lateral Movement
+description: |
+  Lateral movement is the process of an attacker moving from one system to another within a network
+  after they have gained initial access to a system. This can be done through a variety of methods,
+  such as exploiting vulnerabilities in software or using stolen credentials.
+
+  Once an attacker has gained lateral movement within a network, they can then access sensitive data,
+  install malware, or disrupt operations. Lateral movement is a critical step in many cyberattacks,
+  as it allows attackers to gain deeper access to a network and ultimately achieve their goals.
