In the event your company has already fallen victim to a ransomware attack, CISA guidance recommends these steps. Here is some high-level guidance to begin to recover:
01. Isolate Infected Systems: Immediately isolate infected systems from the network to prevent the ransomware from spreading to other devices.
02. Assess the Damage: Assess the extent of the attack and determine which systems and data have been affected. Conduct a thorough investigation to identify the source and scope of the attack.
03. Restore Data from Backups: Restore your data from backups, if available. Ensure that the backups are clean and do not contain any malware.
04. Implement Additional Security Measures: Implement additional security measures to prevent future attacks. This may include updating software, implementing access controls, and training employees on cybersecurity best practices.
05. Conduct a Post-Incident Review: Conduct a post-incident review to evaluate the effectiveness of your response and identify areas for improvement. Use this review to update your incident response plan and improve your security posture.
