10 of the Best Open Source Threat Intelligence Feeds

By Walker Banerd April 30, 2019 security-orchestration-automation-response

In our quest to help security operations and incident response teams work more effectively, we’ve created a list of the top 10 open source threat intelligence feeds.

Each threat feed listed here integrates seamlessly with our award-winning D3 SOAR platform, as do dozens of the top enterprise and subscription-based threat intelligence platforms.

 

1. Department of Homeland Security: Automated Indicator Sharing

Private companies are able to report cyber threat indicators with the DHS, which are then distributed via the Automated Indicator Sharing website. This database helps reduce the effectiveness of simple attacks by exposing malicious IP addresses, email senders, and more.

 

2. FBI: InfraGard Portal

The FBI’s InfraGard Portal provides information relevant to 16 sectors of critical infrastructure. Private and public sector organizations can share information and security events, and the FBI also provides information on cyber attacks and threats that they are tracking.

 

3. @abuse.ch: Ransomware Tracker

Ransomware Tracker collects data related to ransomware attacks so that security teams can check IP addresses and URLs against those that are known to be involved in attacks. The tracker provides detailed information on the servers, sites, and infrastructure that have been exploited by ransomware actors, as well as recommendations for preventing attacks.

 

4. SANS: Internet Storm Center

The Internet Storm Center, formerly known as the Consensus Incidents Database, came to prominence in 2001, when it was responsible for the detection of the “Lion” worm. It uses a distributed sensor network that takes in over 20 million intrusion detection log entries per day to generate alerts regarding security threats. The site also provides analysis, tools, and forums for security professionals.

 

5. VirusTotal: VirusTotal

VirusTotal uses dozens of antivirus scanners, blacklisting services, and other tools to analyze and extract data from files and URLs submitted by users. The service can be used to quickly check incidents like suspected phishing emails, and every submission is retained in its database to build a global picture of cyber threats.

 

6. Cisco: Talos Intelligence

The Talos threat intelligence team protects Cisco customers, but there is a free version of their service available. Talos’ unmatched tools and experience provide information about known threats, new vulnerabilities, and emerging dangers. Talos also provides research and analysis tools.

 

7. VirusShare: VirusShare Malware Repository

VirusShare is an online repository of malware created and maintained by J-Michael Roberts, a digital forensics examiner. The site gives researchers, incident responders, and forensic investigators access millions of malware samples.

 

8. Google: Safe Browsing

The Safe Browsing service identifies dangerous websites and shares the information to raise awareness of security risks. Safe Browsing finds thousands of unsafe sites every day, many of which are legitimate sites that have been compromised by hackers.

 

9. National Council of ISACs: Member ISACs

While some ISAC feeds are quite expensive, others are free. The National Council of ISACs provides a comprehensive list.

 

10. The Spamhaus Project: Spamhaus

Spamhaus is a European non-profit that tracks cyber threats and provides real-time threat intelligence. Spamhaus has developed comprehensive block-lists for known spammers and malware distributors, which they provide to ISPs, email service providers, and individual organizations.

 

D3’s SOAR platform integrates with 200+ security tools, including threat intelligence platforms and open source tools, in order to automatically enrich incident reports with the contextual data that security analysts need to quickly identify genuine threats.
