Free / Open Source Compromise Assessment Tools

OTX ( Open Threat Exchange ):

 

                                     AlienVault provides OTX Endpoint Threat Hunter and its free, fast, and simple.

AlienVault threat hunting service delivers as much threat intelligence power as OTX Endpoint Threat Hunter. It is the Open & free service that natively uses the community-powered threat intelligence of OTX to scan your endpoints for known indicators of compromise (IOCs).

OTX Endpoint Threat Hunter uses the same agent-based approach as expensive endpoint security tools and DIY open source agents without the expense, complexity, or guesswork. 

How It Works

• OTX Endpoint Threat Hunter is available to any registered Open Threat Exchange (OTX) user. It’s free to join OTX.
• To get started, download and install the AlienVault® Agent on the Windows or Linux devices you want to monitor. The AlienVault Agent is immediately ready to find threats.
• You can launch a query on any endpoint from OTX by selecting a pre-defined query that looks for IOCs in one or more OTX pulses.
• Once launched, the AlienVault Agent executes the query, and the results of the query display on a summary page within OTX.

CERTitude:

 

       is a Python-based tool which aims at assessing the compromised perimeter during incident response assignments. It allows analysts to perform large scale scans of Windows-based information systems by searching for behavioral patterns described in IOC (Indicator of Compromise) files. The tool is currently composed of two main components:

• The Python Flask-based web interface, used to configure the scans and visualize their results;
• The scanner that connects to remote targets and runs the search for IOCs.

CERTitude is an open-source tool developed by the CERT-Wavestone. It is brought to you freely, but user support is only provided on a best-effort basis.

Compatibility

CERTitude is compatible with a wide range of target Windows operating systems, from XP / 2003 to Windows 10 / Server 2016. Though CERTitude can be run from a Linux host, it is only fully supported on Windows as some features may not be implemented on Linux.

Features:

• Ability to scan hosts in a way that prevents the target workstation from knowing what the investigator is searching for
• Ability to retrieve some pieces of data from the hosts
• Multiple scanner instances (for IOCs and/or hash scans) can be run at the same time for parallel scanning
• Built with security considerations in mind (protected database, secure communications with hosts using IPSec)

Free Indicators of Compromise (IOC) Tools - FireEye

IOC Finder

FireEye Indicators of Compromise (IOC) Finder is a free tool for collecting host system data and reporting the presence of IOCs. IOCs are open-standard XML documents that help incident responders capture diverse information about threats.

The IOC Finder features:

• Collection of full data, sufficient for general IOC matching requirements
• Usage of a portable storage device for collection from multiple hosts
• IOC hit reporting in simple text, full HTML and full MS Word XML formats
• Generation of reports for specific hosts or all hosts

IOC Editor

 

FireEye Indicators of Compromise (IOC) Editor is a free tool that provides an interface for managing data and manipulating the logical structures of IOCs. IOCs are XML documents that help incident responders capture diverse information about threats, including attributes of malicious files, characteristics of registry changes and artifacts in memory.

The IOC Editor includes:

• Manipulation of the logical structures that define the IOC
• Application of meta-information to IOCs, including detailed descriptions or arbitrary labels
• Conversion of IOCs into XPath filters
• Management of lists of “terms” used within IOCs

IOC Writer

IOC Writer provide a python library that allows for basic creation and editing of OpenIOC objects.

Provide a python library that allows for basic creation and editing of OpenIOC objects. It supports a basic CRUD (Create, Read, Update, Delete) for various items.
Items do not have built in Read operations, since all items can be accesed with built in ElementTree syntax or the use of XPATH to select portions of the IOC.
