Microsoft Chance Intelligence Python Protection Apparatus.

msticpy is a library for InfoSec investigation and having a look
in Jupyter Notebooks. It incorporates capacity to:

  • query log knowledge from a few property
  • enrich the data with Chance Intelligence, geolocations and Azure
    helpful useful resource knowledge
  • extract Indicators of Procedure (IoA) from logs and unpack encoded knowledge
  • perform delicate analysis similar to anomalous session detection and
    time collection decomposition
  • visualize knowledge the usage of interactive timelines, process timber and
    multi-dimensional Morph Charts

It moreover incorporates some time-saving pocket e-book equipment similar to widgets to
set query time boundaries, select and display items from lists, and
configure the pocket e-book surroundings.

The msticpy package deal was once as soon as to start with complex to support
Jupyter Notebooks
authoring for
Azure Sentinel.
While Azure Sentinel continues to be a big point of interest of our art work, we are
extending the data query/acquisition portions to tug log knowledge from
other property (in recent years Splunk, Microsoft Defender for Endpoint and
Microsoft Graph are supported on the other hand we
are actively running on support for info from other SIEM platforms).
Lots of the portions can be used with knowledge from any provide. Pandas
DataFrames are used as the ever-present input and output construction of with regards to
all portions. There may be a data provider to make it blank to and process
knowledge from local CSV knowledge and pickled DataFrames.

The package deal addresses 3 central needs for protection investigators
and hunters:

  • Acquiring and enriching knowledge
  • Analyzing knowledge
  • Visualizing knowledge

We welcome feedback, pc virus critiques, guidelines for brand new choices and contributions.

Setting up

For core arrange:

pip arrange msticpy

If you’re the usage of MSTICPy with Azure Sentinel you will have to arrange with
the “azsentinel” further package deal:

pip arrange msticpy[azsentinel]

or for the most recent dev assemble

pip arrange git+https://github.com/microsoft/msticpy

Documentation

Whole documentation is at ReadTheDocs

Development notebooks for a lot of the modules are inside the
clinical docs/notebooks
folder and accompanying notebooks.

You’ll be able to moreover browse all over the trend notebooks referenced at the end of this report
to appear one of the vital capacity used in context. You’ll be able to play with one of the vital package deal
functions in this interactive demo on mybinder.org.

Log Data Acquisition

QueryProvider is an extensible query library all for Azure Sentinel/Log Analytics,
Splunk, OData
and other log knowledge property. It moreover has explicit support for
Mordor knowledge gadgets and the usage of local knowledge.

Built-in parameterized queries allow difficult queries to be run
from a single function title. Add your personal queries the usage of a smooth YAML
schema.

Data Enrichment

Chance Intelligence providers

The TILookup elegance can seek for IoCs all the way through a few TI providers. built-in
providers include AlienVault OTX, IBM XForce, VirusTotal and Azure Sentinel.

The input is generally a single IoC observable or a pandas DataFrame containing
a few observables. Depending on the provider, it is conceivable you’ll be able to require an account
and an API key. Some providers moreover enforce throttling (specifically for free
tiers), which might perhaps impact appearing bulk lookups.

Azure Helpful useful resource Data, Storage and Azure Sentinel API

The AzureData module incorporates capacity for enriching knowledge relating to Azure host
details with additional host details exposed by means of the Azure API. The AzureSentinel
module means that you can query incidents, retrieve detector and having a look
queries. AzureBlogStorage signifies that you’ll be able to be told and write knowledge from blob storage.

Protection Analysis

This subpackage incorporates a variety of modules helpful for running on protection investigations and having a look:

Anomalous Assortment Detection

Come across odd sequences of events to your Place of business, Full of life Record or other log knowledge.
You’ll be able to extract sessions (e.g. procedure initiated by way of the identical account) and decide and
visualize odd sequences of procedure. For instance, detecting an attacker surroundings
a mail forwarding rule on somebody’s mailbox.

Time Assortment Analysis

Time collection analysis means that you can decide odd patterns to your log knowledge
taking into account not unusual seasonal variations (e.g. the average ebb and drift of
events over hours of the day, days of the week, and so forth.). The use of every analysis and
visualization highlights odd guests flows or instance procedure for any knowledge
set.

Time Assortment

Visualization

Event Timelines

Display any log events on an interactive timeline. The use of the
Bokeh Visualization Library the timeline keep an eye on permits
you to visualize a variety of instance streams, interactively zoom into explicit time
slots and read about instance details for plotted events.

Process Trees

The process tree capacity has two main portions:

  • Process Tree creation – taking a process creation log from a bunch and development
    the parent-child relationships between processes inside the knowledge set.
  • Process Tree visualization – this takes the processed output displays an interactive process tree the usage of Bokeh plots.

There are a choice of software functions to extract explicit individual and partial timber from the processed knowledge set.

Data Manipulation and Device functions

Pivot Functions

Lets you use MSTICPy capacity in an “entity-centric” way.
All functions, queries and lookups that relate to a particular entity type
(e.g. Host, IpAddress, Url) are gathered together as methods of that
entity elegance. So, if you want to do problems with an IP care for, merely load
the IpAddress entity and browse its methods.

base64unpack

Base64 and archive (gz, zip, tar) extractor. It will try to decide any base64 encoded
strings and try decode them. If the outcome seems like one of the supported archive types it
will unpack the contents. The results of every decode/unpack are rechecked for extra
base64 content material subject material and up to a specified depth.

iocextract

Uses not unusual expressions to seek for Indicator of Compromise (IoC) patterns – IP Addresses, URLs,
DNS domains, Hashes, file paths.
Input is generally a single string or a pandas dataframe.

eventcluster (experimental)

This module is supposed to be used to summarize large numbers of
events into clusters of more than a few patterns. Top amount repeating
events can regularly make it difficult to appear unique and engaging items.

This is an unmanaged learning module performed the usage of SciKit Be told DBScan.

auditdextract

Module to load and decode Linux audit logs. It collapses messages sharing the identical
message ID into single events, decodes hex-encoded knowledge fields and performs some
event-specific formatting and normalization (e.g. for process get began events it is going to
re-assemble the process command line arguments proper right into a single string).

syslog_utils

Module to support an investigation of a Linux host with simplest syslog logging enabled.
This incorporates functions for collating host knowledge, clustering logon events and detecting
client sessions containing suspicious procedure.

cmd_line

A module to support he detection of known malicious command line procedure or suspicious
patterns of command line procedure.

domain_utils

A module to support investigation of domain names and URLs with functions to
validate a web page name and screenshot a URL.

Pocket e-book widgets

The ones are made out of the Jupyter ipywidgets collection
and group of workers now not extraordinary capacity useful in InfoSec tasks similar to tick list pickers,
query time boundary settings and instance display into an easy-to-use construction.
