Cybersecurity Threat Intelligence

Welcome to the threat intelligence community:

An ongoing & curated collection of awesome software best practices and remediation techniques, libraries and frameworks, E-books and videos, Technical guidelines and important resources about Threat Intelligence. Thanks to all contributors, you're awesome and wouldn't be possible without you! Our goal is to build a categorized community-driven collection of very well-known resources.

What is Threat Intelligence?

Threat intelligence is data that is collected, processed, and analyzed to understand a threat actor’s motives, targets, and attack behaviors. Threat intelligence enables us to make faster, more informed, data-backed security decisions and change their behavior from reactive to proactive in the fight against threat actors.

Threat intelligence is important for the following reasons:

• sheds light on the unknown, enabling security teams to make better decisions
• empowers cyber security stakeholders by revealing adversarial motives and their tactics, techniques, and procedures (TTPs)
• helps security professionals better understand the threat actor’s decision-making process
• empowers business stakeholders, such as executive boards, CISOs, CIOs and CTOs; to invest wisely, mitigate risk, become more efficient and make faster decisions

CAPEC	The Common Attack Pattern Enumeration and Classification (CAPEC) is a comprehensive dictionary and classification taxonomy of known attacks that can be used by analysts, developers, testers, and educators to advance community understanding and enhance defenses.
CybOX	The Cyber Observable eXpression (CybOX) language provides a common structure for representing cyber observables across and among the operational areas of enterprise cyber security that improves the consistency, efficiency, and interoperability of deployed tools and processes, as well as increases overall situational awareness by enabling the potential for detailed automatable sharing, mapping, detection, and analysis heuristics.
IODEF (RFC5070)	The Incident Object Description Exchange Format (IODEF) defines a data representation that provides a framework for sharing information commonly exchanged by Computer Security Incident Response Teams (CSIRTs) about computer security incidents.
IDMEF (RFC4765)	Experimental - The purpose of the Intrusion Detection Message Exchange Format (IDMEF) is to define data formats and exchange procedures for sharing information of interest to intrusion detection and response systems and to the management systems that may need to interact with them.
MAEC	The Malware Attribute Enumeration and Characterization (MAEC) projects is aimed at creating and providing a standardized language for sharing structured information about malware based upon attributes such as behaviors, artifacts, and attack patterns.
OpenC2	OASIS Open Command and Control (OpenC2) Technical Committee. The OpenC2 TC will base its efforts on artifacts generated by the OpenC2 Forum. Prior to the creation of this TC and specification, the OpenC2 Forum was a community of cyber-security stakeholders that was facilitated by the National Security Agency (NSA). The OpenC2 TC was chartered to draft documents, specifications, lexicons or other artifacts to fulfill the needs of cyber security command and control in a standardized manner.
STIX 2.0	The Structured Threat Information eXpression (STIX) language is a standardized construct to represent cyber threat information. The STIX Language intends to convey the full range of potential cyber threat information and strives to be fully expressive, flexible, extensible, and automatable.

STIX 1.x has been archived here.
TAXII	The Trusted Automated eXchange of Indicator Information (TAXII) standard defines a set of services and message exchanges that, when implemented, enable sharing of actionable cyber threat information across organization and product/service boundaries. TAXII defines concepts, protocols, and message exchanges to exchange cyber threat information for the detection, prevention, and mitigation of cyber threats.
VERIS	The Vocabulary for Event Recording and Incident Sharing (VERIS) is a set of metrics designed to provide a common language for describing security incidents in a structured and repeatable manner. VERIS is a response to one of the most critical and persistent challenges in the security industry - a lack of quality information. In addition to providing a structured format, VERIS also collects data from the community to report on breaches in the Verizon Data Breach Investigations Report (DBIR) and publishes this database online at VCDB.org.

The Detection Maturity Level (DML)	The DML model is a capability maturity model for referencing ones maturity in detecting cyber attacks. It's designed for organizations who perform intel-driven detection and response and who put an emphasis on having a mature detection program. The maturity of an organization is not measured by it's ability to merely obtain relevant intelligence, but rather it's capacity to apply that intelligence effectively to detection and response functions.

Live Cyber Attack Maps

When it comes to real-time cyber attack maps, some are funny, some seem ominous, and all of them tell a story that words alone cannot: cyber attacks never stop.

Kaspersky interactive Cyberthreats Real-Time Map	Our favorite real-time worldwide cyber attack map is from Kaspersky Lab. It looks incredibly sleek. In fact, it can easily be a conversation starter at your next party because it also works great on phones. Click "statistics" to easily find lots of details on where the data is coming from and scan the attack rankings for the day.
Deteque botnet threat map	Next, how about a live botnet threat map? Put on some classical music to go with this one and you'll have your own synchronized "attack show" of real-time botnet attacks around the globe.
Fortinet live cyber attack map	Fortinet real-time attack map. It may not be the most exciting visually, but there are a couple of cool features that make it unique. The bottom left-hand corner has easy to understand (and dramatic) cyber attack statistics, and if you look at the map you'll see a day/night map is subtly overlayed onto the cyber attack map. So you can see where bad actors like to work after dark.
FireEye real-time cyber attack map	Here's what sets this one apart: It is less dramatic with its attack graphics than some of the others, and it also shows the top attacked verticals for the past 30 days.
Bitdefender live cyber threat map	Bitdefender's real-time cyber threat map, which claims to show infections and attacks. Plus, its rapid-fire list of attacks drives home the point for non-technical folks.
SonicWall live cyber attacks map	Another really good looking live cyber attack map is from SonicWall, which was pointed out by a SecureWorld reader. We really like the easy to scan analytics at the bottom of the map which shows which countries are top attack targets right now and the average number of cyber attacks per site for the day, among other things.
Threatbutt	The last one is what you might call an InfoSec classic. Not only does this cyber threat map include the "pew-pew" sound of video games from the '80s, but it flat out says its data comes from the cloud, including the cumulus cloud! And it translates the attacks it is supposedly tracking into phrases like "it's cyber Pompeii" or "we'll just call it a glitch."
