This script is located on my Github, and will have the most recent updated version. It gathers each indicator by type, IE: IPv4, URL, Hostname etc, and then exports each seperate indicator type into CSV files that can be imported into another system like your SIEM. I work in a primarily windows workstation environment and Powershell is my goto language for just about everything since since it is native on every system since Windows 7.īelow is a script I developed to gather indicators from all subscribed pulses on OTX with powershell.

You can ingest your feed to the platform and receive statistics for the contents quickly with many more factors included than what is listed above.So I wanted to automate IoC(Indicators of Compromise) collection and discovered AlienVault OTX product. If you want to evaluate your intelligence feeds please contact us to set up a trial. ![]() We will expand on this report each month. If you have open source feeds you want us to add to the report please contact us. This is why we weigh the originator score more heavily than the overlap score. For retrieving the OTX data, we’re going to choose the HTTP Built-in connector and then the HTTP action. Low overlap makes a feed very valuable, as it provides data no other feed provides, but the reverse isn’t automatically true: a feed may have a high overlap score, but still be very valuable because it is often the first to report observables. These indicators are then written in json format and the pulse is updated via the OTX API. We pull all active/online and verified phishing URLs from phishtank API and parse the file for URLs reported as IRS phishing scams. In the second chart, we have added the overlap percentage: what percentage of the data in a feed also appears in other feeds. Open Threat Exchange is an open community that allows participants to learn about the latest threats, research indicators of compromise observed in their environments, share threats they have identified, and automatically update their security infrastructure with the latest indicators to defend their environment. This is an automated process that is updated hourly by the Vertek MTI Labs Team.
