Top 10 Malware Feeds to Supercharge Your Threat Detection

Cyber threats are evolving at an alarming rate. According to AVG, there are around 190,000 new malware attacks every second, and the AV-TEST Institute detects over 450,000 new malicious programs and potentially unwanted applications (PUA) every single day. With such a massive wave of threats, staying ahead isn't just a challenge, it's a necessity.

That's where malware feeds come in. These real-time data sources help security teams detect and respond to emerging threats before they cause damage. But with so many options out there, which ones are truly worth your time?

In this article, we break down the top 10 malware feeds you should use to strengthen your security and protect your organization.

What are Malware Feeds?

Malware feeds are continuous streams of data about potential and active security threats, which are necessary to detect and respond to cyber threats. They give you insight into malware patterns and behavior so you can identify and mitigate these threats.

A malware feed, being a threat intelligence feed, can be defined as a "real-time, continuous data stream that gathers information related to cyber risks or threats," according to Crowdstrike.

Through these feeds, you get accurate, high-quality data about attackers, threats, and Indicators of Compromise (IoCs), which helps your overall cybersecurity posture.

Not all threat intelligence feeds are created equal, there are big differences in the sources and types of data they provide. Good malware feeds focus on different types of threats. Understanding the different types of malware feeds and their characteristics is the first step to using them effectively.

Types of Malware Feeds

Malware feeds can be broadly categorized into open-source, commercial, and community-driven, each serving different cybersecurity needs.

1. Open-source malware feeds are usually free or low-cost, and they are managed by online communities that share knowledge. While these feeds can give you valuable information, they may not have the coverage of commercial products.

2. Commercial malware feeds are products you buy from third-party providers, and they offer more support and reliability than open-source feeds.

3. Community-driven malware feeds rely on user contributions, which can make them more relevant but may not match the depth of commercial feeds.

Choosing a malware feed should be based on the organization's specific needs, considering cost, reliability, and relevance. In many cases, a hybrid approach that combines different types of sources provides more comprehensive threat intelligence.

Microsoft states that threat intelligence "includes data and analysis that give security teams a comprehensive view of the threat landscape," so a hybrid strategy is an excellent idea.

Good malware feeds should give you full threat data and real-time insights that are actionable, relevant, accurate, and trustworthy. So, let's take a look at some of the most valuable feeds available today.
