Today, CISA is announcing the creation of the Ransomware Vulnerability Warning Pilot (RVWP). Through the RVWP, CISA: Proactively identifies information systems—belonging to critical infrastructure entities—that contain vulnerabilities commonly associated with ransomware intrusions. Notifies the owners of the affected information systems, which enables the owners to mitigate the vulnerabilities before damaging intrusions occur. Review the RVWP webpage for details, including information on the authorities and services CISA leverages to enable RVWP notifications. Please share your thoughts.
