Sources

Most of the resources listed below provide lists and/or APIs to obtain (hopefully) up-to-date information with regards to threats. Some consider these sources as threat intelligence, opinions differ however. A certain amount of (domain- or business-specific) analysis is necessary to create true threat intelligence.

Critical Stack Intel	The free threat intelligence parsed and aggregated by Critical Stack is ready for use in any Bro production system. You can specify which feeds you trust and want to ingest.
Cymon	Cymon is an aggregator of indicators from multiple sources with history, so you have a single interface to multiple threat feeds. It also provides an API to search a database along with a pretty web interface.
Deepviz Threat Intel	Deepviz offers a sandbox for analyzing malware and has an API available with threat intelligence harvested from the sandbox.
Emerging Threats Firewall Rules	A collection of rules for several types of firewalls, including iptables, PF and PIX.
Emerging Threats IDS Rules	A collection of Snort and Suricata rules files that can be used for alerting or blocking.
FireHOL IP Lists	A firewall blacklist composed from IP lists, providing maximum protection with minimum false positives. Suitable for basic protection on all internet facing servers, routers and firewalls.
Hail a TAXII	Hail a TAXII.com is a repository of Open Source Cyber Threat Intelligence feeds in STIX format. They offer several feeds, including some that are listed here already in a different format, like the Emerging Threats rules and PhishTank feeds.
I-Blocklist	I-Blocklist maintains several types of lists containing IP addresses belonging to various categories. Some of these main categories include countries, ISPs and organizations. Other lists include web attacks, TOR, spyware and proxies. Many are free to use, and available in various formats.
MalwareDomains.com	The DNS-BH project creates and maintains a listing of domains that are known to be used to propagate malware and spyware. These can be used for detection as well as prevention (sinkholing DNS requests).
OpenPhish Feeds	OpenPhish receives URLs from multiple streams and analyzes them using its proprietary phishing detection algorithms. There are free and commercial offerings available.
PhishTank	PhishTank delivers a list of suspected phishing URLs. Their data comes from human reports, but they also ingest external feeds where possible. It's a free service, but registering for an API key is sometimes necessary.
SSL Blacklist	SSL Blacklist (SSLBL) is a project maintained by abuse.ch. The goal is to provide a list of "bad" SSL certificates identified by abuse.ch to be associated with malware or botnet activities. SSLBL relies on SHA1 fingerprints of malicious SSL certificates and offers various blacklists
Strongarm, by Percipient Networks	Strongarm is a DNS blackhole that takes action on indicators of compromise by blocking malware command and control. Strongarm aggregates free indicator feeds, integrates with commercial feeds, utilizes Percipient's IOC feeds, and operates DNS resolvers and APIs for you to use to protect your network and business. Strongarm is free for personal use.
ThreatMiner	ThreatMiner has been created to free analysts from data collection and to provide them a portal on which they can carry out their tasks, from reading reports to pivoting and data enrichment. The emphasis of ThreatMiner isn't just about indicators of compromise (IoC) but also to provide analysts with contextual information related to the IoC they are looking at.
VirusShare	VirusShare.com is a repository of malware samples to provide security researchers, incident responders, forensic analysts, and the morbidly curious access to samples of malicious code. Access to the site is granted via invitation only.

Formats

Standardized formats for sharing Threat Intelligence (mostly IOCs).

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.
STIX	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 does not only allow tool-agnostic fields, but also provides so-called test mechanisms that provide means for embedding tool-specific elements, including OpenIOC, Yara and Snort.
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 structuref 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.
