Malware Patrol

We are a company of threat data experts based in the USA and Brazil. Our history is one of community spirit and dedication to internet security that began in 2005 when a group of like-minded individuals began sharing malicious links through a mailing list. The decade plus we have spent collecting, analyzing, and sharing data has allowed us to develop an extensive network of sensors, sharing agreements, and community contributors, resulting in a vast database of unique and historically rich – intelligent – threat data.

Our automated systems verify the data every day to ensure that it contains only active threats, and we are continually updating the technology we use to scour the web for malicious campaigns. Malware Patrol’s indicators of compromise (IOCs) are now used by thousands to protect networks and assets in more than 175 countries and we offer commercial and non-commercial versions of our data.

Commercial Data

Enterprise – A wide range of data – malware samples, malicious IPs, C&Cs, anti-mining, and more – for security researchers and enterprises. For those with specific data and/or ingestion requirements, we can fully customize feed contents and/or formats.

Business Protect – A data package with the goal of protecting your customers and networks against malware infections, the transmission of compromised data, and communications with botnets and command and control (C2s) servers.

e-Assets – Insight into threats related to your company’s most valuable electronic assets – domains, IP addresses, system access credentials.

Non-Commercial Block Lists 

The data offered in these block lists is strictly for personal or non-commercial use, such as home computers and internal networks. It cannot be used to protect external customers or included in any commercial security products or services. The block lists are available in a variety of formats, compatible with the most popular content filters, firewalls, and proxy systems.

Free Guard – Completely free, updated every 72 hours.

Basic Defense – Monthly and annual subscription options, updated every 4 hours.
