AT&T Alien Labs Open Threat Exchange (OTX) is an open and free platform that allows security professionals to share, research, and validate the latest threats, trends, and techniques. With over 200,000 global security and IT professionals submitting data daily, OTX is among the world’s largest open threat intelligence communities. It provides context and details on threats, including threat actors, organizations and industries targeted, and related indicators of compromise. When users contribute threat indicators to OTX, they can also classify, search, and filter data based on specific industries to identify the emerging threats that are most relevant to their own work. OTX adversary pages compile threat information from various sources about specific threat actors and groups. The platform automatically analyzes suspicious threats by running files/URLs through the Alien Labs malware and threat analysis engine, which includes multiple layers of automated checks, analytics, and machine learning (ML). OTX is a flexible and free model for sharing and consuming threat intelligence via the platform’s integrations with any security tooling, and its community is growing at a staggering rate.
