- THE MTS-ISAC PROVIDED MARITIME CYBER THREAT INFORMATION TO PERSONNEL IN OVER 180 ORGANIZATIONS, WITH INFORMATION SOMETIMES GOING TO DOZENS OF INDIVIDUALS WITHIN AN ORGANIZATION. THESE ORGANIZATIONS INCLUDED PRIVATE INDUSTRY CRITICAL INFRASTRUCTURE STAKEHOLDERS AS WELL AS FEDERAL AGENCY ORGANIZATIONS (WHICH PROVIDED NO RESOURCES OR FUNDING TO THE MTS-ISAC IN 2025). THE INFORMATION PROVIDED TO THESE ORGANIZATIONS WAS TIMELY AND INCLUDED IN WHOLE OR IN PART (DEPENDING ON THEIR PARTICIPATION WITH THE MTS-ISAC) ACCESS TO: 98 CYBERSECURITY ADVISORIES, 844 INDICATOR BULLETINS, MORE THAN 12 WEBINARS, AND MULTIPLE OPEN CALLS TO DISCUSS CYBERSECURITY. THIS WORK WAS ACCOMPLISHED AS THE MTS-ISAC RESPONDED TO OVER 110 REQUESTS FOR INFORMATION AND ANALYZED 1,762 THREAT INFORMATION SHARES (WITH ONE SHARE SOMETIMES CONTAINING DOZENS OF ATTACHMENTS AND HUNDREDS OF DATA POINTS NEEDING REVIEW). THE OUTCOMES OF THIS WORK PROVIDED THE FOLLOWING RESULTS TO MARITIME CRITICAL INFRASTRUCTURE STAKEHOLDERS: EARLY WARNING OF CYBER THREAT ACTIVITY, INCLUDING PHISHING, CREDENTIAL STUFFING, SCANNING, VULNERABILITY EXPLOITATIONS, AND OTHER ATTACK BEHAVIORS; AND CYBERSECURITY BEST PRACTICES THAT COULD BE APPLIED TO COUNTER THOSE ATTACKS.
- THE MTS-ISAC ORGANIZED THE ANNUAL MARITIME CYBERSECURITY SUMMIT. THE SUMMIT CONSISTED OF TWO DAYS OF KEYNOTES, DISCUSSIONS, AND PRESENTATIONS ON BOTH TECHNICAL AND NON-TECHNICAL MARITIME CYBERSECURITY CHALLENGES AND A THIRD DAY DEDICATED TO MARITIME CYBERSECURITY PRACTITIONER TRAINING.

IN ADDITION TO DISCUSSING THE CHALLENGES, INFORMATION WAS PRESENTED ON BEST PRACTICES, UPDATED CYBERSECURITY STRATEGIES, USE CASES, AND LESSONS LEARNED. THE SUMMIT RESULTED IN GREATER UNDERSTANDING OF HOW TO APPROACH CYBERSECURITY CHALLENGES IN THE MARITIME SECTOR AND HELPED ATTENDEES CREATE NEW PEER RELATIONSHIPS THAT PREVIOUSLY DID NOT EXIST. THE SUMMIT DIRECTLY SUPPORTS THE MTS-ISAC'S MISSION OF IMPROVING CYBER RESILIENCY OF THE MARITIME SECTOR.
