The Cybersecurity and Infrastructure Security Agency’s (CISA) Chemical Security Assessment Tool (CSAT) was the target of a cybersecurity intrusion by a malicious actor from January 23-26, 2024. While CISA’s investigation found no evidence of exfiltration of data, this intrusion may have resulted in the potential unauthorized access of Top-Screen surveys, Security Vulnerability Assessments, Site Security Plans, Personnel Surety Program (PSP) submissions, and CSAT user accounts.

Following the reporting requirements under the Federal Information Security Modernization Act, CISA notified participants in the Chemical Facility Anti-Terrorism Standards (CFATS) program about the intrusion and the potentially impacted information.

In addition to the notifications, CISA is hosting two webinars for stakeholders during which we will review the information provided in the frequently asked questions. Both webinars will cover the same material. The webinars will be held on Monday, June 24, 2024, at 2:30 pm ET (11:30 am PT) and Tuesday, July 9, 2024, at 2:30 pm ET (11:30 am PT). 

This registration is for the June 24, 2024, webinar. To register for the July 9 webinar, visit the July 9 webinar registration webpage.
