If a ransomware incident occurs at your organization, the FBI, CISA and NSA recommend the following actions:
- Follow the Ransomware Response Checklist on p. 11 of the CISA-Multi-State Information Sharing and Analysis Center (MS-ISAC) Joint Ransomware Guide.
- Scan your backups. If possible, scan your backup data with an antivirus program to check that it is free of malware.
- Report incidents immediately to CISA at https://us-cert.cisa.gov/report, a local FBI Field Office, or U.S. Secret Service Field Office.
- Apply incident response best practices found in the joint advisory from Australia, Canada, New Zealand, the United Kingdom, and the United States on Technical Approaches to Uncovering and Remediating Malicious Activity.
