Dropping Python 3.6 support

As of this release, we only officially support Python 3.8 and above. Python 3.6 is nearly 8 years old and is no longer supported by a lot of packages that we depend on. There are also a bunch of features such as dataclasses and better type hinting that we'd like to start using.

 

We will try to support Python 3.6 if the fixes required are small and contained but make no guarantees of it working completely on
Python prior to 3.8.

 


Package re-organization and module search

One of our main goals for v2.0.0 was to re-organize MSTICPy to be more logical and easier to use and maintain. Several years of organic growth had seen modules created in places that seemed like a good idea at the time but did not age well.

The discussion about the V2 structure can be found on our GitHub repo here: #320.

 

Due to the re-organization, many features are no longer in places where they used to be imported from!

 

We have tried to maintain compatibility with old locations by adding "glue" modules. These allow import of many modules from their previous locations but will issue a Deprecation warning if loaded from the old location. The warning will contain the new location of the module - so, you should update your code to point to this new location.

 

This table gives a quick overview of the V2.0 structure

 

folder description
msticpy.analysis data analysis functions - timeseries, anomalies, clustering
msticpy.auth authentication and secrets management
msticpy.common commonly used utilities and definitions (e.g. exceptions)
msticpy.config configuration and settings UI
msticpy.context enrichment modules geoip, ip_utils, domaintools, tiproviders, vtlookup
msticpy.data data acquisition/queries/storage/uploaders
msticpy.datamodel entities, soc objects
msticpy.init package loading and initialization - nbinit, pivot modules
msticpy.nbwidgets nb widgets modules
msticpy.transform simple data processing - decoding, reformatting, schema change, process tree
vis visualization modules including browsers

 

Notable things that have moved:

  • most things from the sectools folder have migrated to context, transform or analysis
  • most things from the nbtools folder have migrated to either:
    • msticpy.init - (not to be confused with __init__) - package initialization
    • msticpy.vis - visualization modules
  • pivot functionality has moved to msticpy.init

 

Module Search

If you are having trouble finding a module, we have added a simple search function:

 

    import msticpy as mp
    mp.search("riskiq")

Matches of module names will be returned in a table with links to the module documentation:

 

Modules matching 'riskiq'

Module Help
msticpy.context.tiproviders.riskiq msticpy.context.tiproviders.riskiq

 


Simplifying imports in MSTICPy

The root module in MSTICPy now has several modules and classes that can be directly accessed from it (rather than
having to import them individually).

 

We've also decided to adopt a new "house style" of importing msticpy as the alias mp. Slavishly copying the idea from some of great packages that we use (pandas -> pdnumpy -> np, networkx -> nx) we thought it would save a bit of typing. You are free to adopt or ignore this style - it has no impact on the functionality.

 

    import msticpy as mp
    mp.init_notebook()
    qry_prov = mp.QueryProvider("MDE")
    ti = mp.TILookup()

Many commonly used classes and functions are exposed as attributes of msticpy (or mp).

 

Also, a number of frequently used classes are imported by default in the init_notebookfunction, notably all of the entity classes. This makes it easier to use pivot functions without any initialization or import steps.

 

    import msticpy as mp
    mp.init_notebook()

    # IpAddress can be used without having to import it.
    IpAddress.whois("123.45.6.78")

init_notebook improvements

  • You no longer need to supply the namespace=globals() parameter when calling from a notebook. init_notebook will automatically obtain the notebook global namespace and populate imports into it.
  • The default verbosity of init_notebook is now 0, which produces minimal output - use verbosity=1 or verbosity=2 to get more
    detailed reporting.
  • The Pivot subsystem is automatically initialized in init_notebook.
  • All MSTICPy entities are imported automatically.
  • All MSTICPy magics are initialized here.
  • Most MSTICPy pandas accessors are initialized here (some, which require optional packages, such as the timeseries accessors are
    not initialized by default).
  • init_notebook supports a config parameter - you can use this to provide a custom path to a msticpyconfig.yaml overriding the usual defaults.
  • searching for a config.json file is only enabled if you are running MSTICPy in Azure Machine Learning.

 


Folium map update - single function, layers, custom icons

The Folium module in MSTICPy has always been a bit complex to use since it normally required that you convert IP addresses to MSTICPy
IpAddress entities before adding them to the map.

 

You can now plot maps with a single function call from a DataFrame containing IP addresses or location coordinates. You can group the data
into folium layers, specify columns to populate popups and tooltips and to customize the icons and coloring.

 

Folium-one-line.png

folium_layers.pngfolium_tooltips.png

plot_map

A new plot_map function (in the msticpy.vis.foliummap module) that lets you plot mapping points directly from a DataFrame. You can
specify either an ip_column or coordinates columns (lat_column and long_column). In the former case, the geo location of the IP address
is looked up using the MaxMind GeoLiteLookup data.

 

You can also control the icons used for each marker with the icon_column parameters. If you happen to have a column in your data that contains names of FontAwesome or GlyphIcons icons you can use that column directly.
More typically, you would combine the icon_column with the icon_map parameter. You can specify either a dictionary or a function. For a dictionary, the value of the row in icon_column is used as a key - the value is a dictionary of icon parameters passed to the Folium.Icon class. For a function, the icon_columnvalue is passed to the function as a single parameter and the return value
should be a dictionary of valid parameters for the Icon class.

 

folium_class_icons.png


You can read the documentation for this function in the docs.

 

plot_map pandas accessor

Plot maps from the comfort of your own DataFrame!
Using the msticpy mp_plot accessor you can plot maps directly from a pandas DataFrame containing IP or location information.
The folium_map function has the same syntax as plot_mapexcept that you omit the data parameter.

 

    df.mp_plot.folium_map(ip_column="ip", layer_column="CountryName")
 

folium_accessor.png

 

Layering, Tooltips and Clustering support

In plot_map and .mp_plot.folium_map you can specify a layer_column parameter. This will group the data by the values in that column and create an individually selectable/displayable layer in Folium. For performance and sanity reasons this should be a column with a relatively small number of discrete values.

 

Clustering of markers in the same layer is also implemented by default - this will collapse multiple closely located markers
into a cluster that you can expand by clicking or zooming.

 

You can also populate tooltips and popups with values from one or more column names.

 

"Classic" interface

The original FoliumMap class is still there for more manual control. This has also been enhanced to support direct plotting from IP, coordinates or GeoHash in addition to the existing IpAddress and GeoLocation entities. It also supports layering and clustering.

 


Threat Intelligence providers - async support

When you have configured more than one Threat Intelligence provider, MSTICPy will execute requests to each of them asynchronously. This will bring big performance benefits when querying IoCs from multiple providers. 

Note: requests to individual providers are still executed synchronously since we want to avoid swamping provider services with multiple
simultaneous requests.

 

We've also implemented progress bar tracking for TI lookups, giving a visual indication of progress when querying multiple IoCs.

Combining the progress tracking with asynchronous operation means that not only is performing lookups for lots of observables faster
but you will also less likely to be left guessing whether or not your kernel has hung.

 

Note that asynchronous execution only works with lookup_iocs and TI lookups
done via the pivot functions. lookup_ioc will run queries to multiple providers in seqence
so will usually be a lot slower than lookup_iocs.

 

    # don't do this
    ti_lookup.lookup_ioc("12.34.56.78")
    # do this (put a single IoC in a list)
    ti_lookup.lookup_iocs(["12.34.56.78"])

 

TI Providers are now also loaded on demand - i.e., only when you have a configuration entry in your msticpyconfig.yaml for that provider.
This prevents loading of code (and possibly import errors) due to providers which you are not intending to use.

 

Finally, we've added functions to enable and disable providersafter loading TILookup:

 

    from msticpy.context import TILookup
    ti_lookup = TILookup()

    iocs = ['162.244.80.235', '185.141.63.120', '82.118.21.1', '85.93.88.165']
    ti_lookup.lookup_iocs(iocs, providers=["OTX", "RiskIQ"])

Time Series simplified - analysis and plotting

Although the Time Series functionality was relatively simple to use, it previously required several disconnected steps to compute
the time series, plot the data, extract the anomaly periods. Each of these needed a separate function import. Now you can do all of these
from a DataFrame via pandas accessors. (currently, there is a separate accessor -df.mp_timeseries - but we are still working on consolidating our pandas accessors so this may change in the future.)

 

Because you typically still need these separate outputs, the accessor has multiple methods:

  • df.mp_timeseries.analyze - takes a time-summarized DataFrame and returns the results of a time-series decomposition
  • df.mp_timeseries.plot - takes a decomposed time-series and plots the anomalies
  • df.mp_timeseries.anomaly_periods - extracts anomaly periods as a list of time ranges
  • df.mp_timeseries.anomaly_periods - extracts anomaly periods as a list of KQL query clauses
  • df.mp_timeseries.apply_threshold - applies a new anomaly threshold score and returns the results.

See documentation for these functions.

 

Analyze data to produce time series.

    df = qry_prov.get_networkbytes_per_hour(...)
    ts_data = df.mp_timeseries.analyze()

Analyze and plot time series anomalies

    df = qry_prov.get_networkbytes_per_hour(...)
    ts_data = df.mp_timeseries.analyze().mp_timeseries.plot()

 

TimeSeriesAnomalieswithRangeTool.png

 

Analyze and retrieve anomaly time ranges

    df = qry_prov.get_networkbytes_per_hour(...)
    df.mp_timeseries.analyze().mp_timeseries.anomaly_periods()
    [TimeSpan(start=2019-05-13 16:00:00+00:00, end=2019-05-13 18:00:00+00:00, period=0 days 02:00:00),
     TimeSpan(start=2019-05-17 20:00:00+00:00, end=2019-05-17 22:00:00+00:00, period=0 days 02:00:00),
     TimeSpan(start=2019-05-26 04:00:00+00:00, end=2019-05-26 06:00:00+00:00, period=0 days 02:00:00)]
    df = qry_prov.get_networkbytes_per_hour(...)
    df.mp_timeseries.analyze().mp_timeseries.kql_periods()
    '| where TimeGenerated between (datetime(2019-05-13 16:00:00+00:00) .. datetime(2019-05-13 18:00:00+00:00)) or TimeGenerated between (datetime(2019-05-17 20:00:00+00:00) .. datetime(2019-05-17 22:00:00+00:00)) or TimeGenerated between (datetime(2019-05-26 04:00:00+00:00) .. datetime(2019-05-26 06:00:00+00:00))'

 


DataFrame to graph/network visualization

You can convert a pandas DataFrame into a NetworkX graph or plot directly as a graph using Bokeh interactive plotting.

 

You pass the functions the column names for the source and target nodes to build a basic graph. You can also name other columns to be node or edge attributes. When displayed these attributes are visible as popup details courtesy of Bokeh’s Hover tool.

    proc_df.head(100).mp_plot.network(
        source_col="SubjectUserName",
        target_col="Process",
        source_attrs=["SubjectDomainName", "SubjectLogonId"],
        target_attrs=["NewProcessName", "ParentProcessName", "CommandLine"],
        edge_attrs=["TimeGenerated"],
    )

Pivots - easy initialization/dynamic data pivots

The pivot functionality has been overhauled. It is now initialized automatically in init_notebook - so you don't have to import and create an instance of Pivot.

 

Pivot-queries.png

Better data provider support

Previously, queries from data providers were added at initialization of the Pivot subsystem. This meant that you had to:

  • create your query providers before starting Pivot
  • every time you created a new QueryProvider instance you had to re-initialize Pivot.

Data providers now dynamically add relevant queries as pivot functions when you authenticate to the provider.

 

Multi-instance provider support

Some query providers (such as MS Sentinel) support multiple instances. Previously this was not well supported in Pivot functions - the last
provider loaded would overwrite the queries from earlier providers. Pivot now supports separate instance naming so that each Workspace has a separate instance of a given pivot query.

 

Threat Intelligence pivot functions

The naming of the Threat Intelligence pivot functions has been considerably simplified.

 

VirusTotal and RiskIQ relationship queries should now be available as pivot functions (you need the VT 3 and PassiveTotal packages installed
respectively to enable this functionality).

 

More Defender query pivots

A number of MS Defender queries (using either the MDE or MSSentinel QueryProviders) are exposed as Pivot functions.

 


Consolidating Pandas accessors

Pandas accessors let you extend a pandas DataFrame or Series with custom functions. We use these in MSTICPy to let you call analysis or visualization functions as methods of a DataFrame.

 

Most of the functions previously exposed as pandas accessors, plus some new ones, have been consolidated into two main accessors.

  • df.mp - contains all of the transformation functions like base64 decoding, ioc searching, etc.
  • df.mp_plot - contains all of the visualization accessors (timeline, process tree, etc.)

mp accessor

  • b64extract - base64/zip/gzip decoder
  • build_process_tree - build process tree from events
  • ioc_extract - extract observables by pattern such as IPs, URLs, etc.
  • mask - obfuscate data to hide PII
  • to_graph - transform to NetworkX graph

mp_plot accessor

  • folium_map - plot a Folium map from IP or coordinates
  • incident_graph - plot an incident graph
  • matrix - plot correlation between two values
  • network - plot graph/network from tabular data
  • process_tree - plot process tree from process events
  • timeline - plot a multi-grouped timeline of events
  • timeline_duration - plot grouped start/end of event sequence
  • timeline_values - plot timeline with a scalar values

 

folium_accessor.png

 

Example usage (note: the required parameters, if any, are not shown in these examples)

 

    df.mp.ioc_extract(...)
    df.mp.to_graph(...)
    df.mp.mask(...)

    df.mp_plot.timeline(...)
    df.mp_plot.timeline_values(...)
    df.mp_plot.process_tree(...)
    df.mp_plot.network(...)
    df.mp_plot.folium_map(...)

One of the benefits of using accessors is the ability to chain them into a single pandas expression (mixing with other pandas methods).

 

    (
        my_df
        .mp.ioc_extract(...)
        .groupby(["IoCType"])
        .count()
        .reset_index()
        .mp_plot.timeline(...)
    )

 


MS Sentinel workspace configuration

From MPConfigEdit you can more easily import and update your Sentinel workspace configuration.

 

Resolve Settings

If you have a minimal configuration (e.g., just the Workspace ID and Tenant ID) you can retrieve other values such as Subscription ID, Workspace Name and Resource Group and save them to your configuration using the Resolve Settings button.

 

mpconfig_edit_new_workspace.png

 

Import Settings from URL

You can copy the URL from the Sentinel portal and paste it into the MPConfigEdit interface. It will extract and lookup the full details of the workspace to save to your settings.

 

Expanded Sentinel API support

The functions used to implement the above functionality are also available standalone in the MSSentinel class.

 

    from msticpy.context.azure import MicrosoftSentinel

    MicrosoftSentinel.get_workspace_details_from_url(url)
    MicrosoftSentinel.get_workspace_name(ws_id)
    MicrosoftSentinel.get_workspace_settings(resource_id)
    MicrosoftSentinel.get_workspace_settings_by_name(ws_name, sub_id, res_group)
    MicrosoftSentinel.get_workspace_id(ws_name, sub_id, res_group)

 


MS Defender queries available in MS Sentinel QueryProvider

Since Sentinel now has the ability to import Microsoft Defender data, we've made the Defender queries usable from the MS Sentinel provider.

 

    qry_prov = QueryProvider("MSSentinel")
    qry_prov.MDE.list_host_processes(host_name="my_host")

 

This is not specific to Defender queries but is a more generic functionality that allows us to share compatible queries between different QueryProviders. Many of the MS Defender queries are also now available as Pivot functions.

 


Microsoft Sentinel QueryProvider changes

There are several changes specific to the MS Sentinel query provider:

 

  • The MS Sentinel provider now support a timeout parameter allowing you lengthen and shorten the default.

      qry_prov.MDE.list_host_processes(
          host_name="myhost",
          timeout=600,
      )
  • You can set other options supported by Kqlmagic when initializing the provider

        qry_prov = mp.QueryProvider("MSSentinel", cloud="government")
  • You can specify a workspace name as a parameter when connecting instead of creating a WorkSpaceConfig instance or supplying
    a connection string. To use the Default workspace supply "Default" as the workspace name.

        qry_prov.connect(workspace="MyWorkspace")

 


New queries

Several new Sentinel and MS Defender queries have been added.

 

 

Provider Query Description
AzureNetwork network_connections_to_url List of network connections to a URL
LinuxSyslog notable_events Returns all syslog activity for a host
LinuxSyslog summarize_events Returns a summary of activity for a host
LinuxSyslog sysmon_process_events Get Process Events from a specified host
WindowsSecurity account_change_events Gets events related to account changes
WindowsSecurity list_logon_attempts_by_ip Retrieves the logon events for an IP Address
WindowsSecurity notable_events Get noteable Windows events not returned in other queries
WindowsSecurity schdld_tasks_and_services Gets events related to scheduled tasks and services
WindowsSecurity summarize_events Summarizes a the events on a host

 

Over 30 MS Defender queries can now also be used in MS Sentinel workspaces if MS Defender for Endpoint/MS Defender 365 data is connected to Sentinel.

 

Additional Azure resource graph queries

 

Provider Query Description
Sentinel get_sentinel_workspace_for_resource_id Retrieves Sentinel/Azure monitor workspace details by resource ID
Sentinel get_sentinel_workspace_for_workspace_id Retrieves Sentinel/Azure monitor workspace details by workspace ID
Sentinel list_sentinel_workspaces_for_name Retrieves Sentinel/Azure monitor workspace(s) details by name and resource group or subscription_id

 

See the updated built-in query list in the MSTICPy documentation.


Documentation additions and improvements

The documentation for V2.0 is available at https://msticpy.readthedocs.io (previous versions are still online and can be accessed through
the ReadTheDocs interface).

 

New and updated documents

 

API documentation

As well as including all of the new APIs, the API documentation has been split into a module-per-page to make it easier to read and navigate.

 

InterSphinx

The API docs also now support "InterSphinx".
This means that references in the MSTICPy documentation to objects in other packages that support InterSphinx (e.g., Python standard library, pandas, Bokeh) have active links that will take you to the native documentation for that item.

 

Sample notebooks

The sample notebooks for most of these features have been updated along the same lines as the documentation. See MSTICPy Sample notebooks.

 

There are three new notebooks:

  • ContiLeaksAnalysis
  • Network Graph from DataFrame
  • What's new in MSTICPy 2.0

 

ContiLeaks notebook added to MSTICPy Repo

We are privileged to host Thomas's awesome ContiLeaks notebook that covers investigation into attacker forum chats including
some very cool illustration of using natural language translation in a notebook.

Thanks to Thomas Roccia (aka @fr0gger) for this!

 


Miscellaneous improvements

 

  • MSTICPy network requests use a custom User Agent header so that you
    can identify or track requests from MSTICPy/Notebooks.
  • GeoLiteLookup and the TOR and OpenPageRank providers no longer try
    to download data files at initialization - only on first use.
  • GeoLiteLookup tries to keep a single instance if the parameters
    that you initialize it with are the same
  • Warnings cleanup - we've done a lot of work to clean up warnings -
    especially deprecation warnings.
  • Moved some remaining Python unittest tests to pytest
