Protection Against Malware and Ransomware

Block Lists for the Security Community Since 2005

We offer non-commercial block lists in formats compatible with several of the most commonly used open source DNS, firewall, IPS/IDS and AV platforms – SpamAssassin, ClamAV, and SquidGuard, among others. These lists include verified data for active malware and ransomware.

non-commercial subscription

Configuration guides for several commonly used systems are available on our website. If you still need help, check out our tech support options. Or, better yet, write a configuration guide (that we don’t already have) and submit it to us for a FREE Basic Defense Block List subscription ($40 value).

The Malware Patrol project began over a decade ago as a group sharing malicious URLs. This community, more active than ever, continues to collect, analyze, and monitor malware. We gladly provide a platform and resources to facilitate the collection and distribution of our community’s data because we believe that information sharing is one of the most effective ways to fight cyber threats.

Participate in our community. Send your suspect emails and URLs to void@malware.com.br or set up a spam trap. All submissions are verified hourly and any new malicious URLs will be immediately added to our block lists. A single submission could help protect thousands of users — and our regular contributors are eligible for a FREE Basic Defense Block List subscription ($40 value).


If you plan to use our data to protect your customers, a commercial license is required.
