All about IOC files: what they are and how to write them.

Contents

What Are They?

IOC files are a list of MD5 hashes, IP addresses, or domains. The lists must all be of the same indicator type. Each entry must be on it's own line. No formatting, quotes, or escape characters are necessary. Entries are processed as chained OR statements (e.g. ipaddr:8.8.8.8 OR ipaddr:127.0.01).
