OSTrICa (Open Source Threat Intelligence Collector) is an open source plugin-oriented framework designed to collect and visualize threat intelligence information from multiple sources. The framework enables SOC analysts, incident responders, attack investigators, and cybersecurity analysts to correlate Indicators of Compromise (IoCs), network traffic patterns, and other collected data to enhance their defensive capabilities. OSTrICa utilizes a plugin-based architecture that allows automatic collection and visualization of threat intelligence data from open, internal, and commercial sources. This approach provides organizations with threat intelligence capabilities without requiring significant budget investments in commercial Threat Intelligence Platforms and Programs (TIPP). The collected intelligence data can be analyzed and integrated into existing cybersecurity defense strategies to improve threat detection and response capabilities. The framework addresses the need for accessible threat intelligence tools in organizations that may not have extensive budgets for commercial solutions.
