FBI and CISA Warn of Medusa Ransomware Threat Targeting Critical Sectors

The Medusa ransomware group has compromised over 300 organizations and employs double extortion tactics, prompting urgent cybersecurity measures.

The Medusa ransomware group has targeted over 300 victims since 2021, focusing on critical sectors such as healthcare, education, and technology.
Medusa uses a double extortion model, encrypting data and threatening to release it unless a ransom is paid.
The FBI and CISA recommend enabling multi-factor authentication (MFA) for webmail accounts like Gmail and Outlook, VPNs, and critical system access to enhance security.
Organizations are advised to maintain segmented, secure backups of sensitive data and regularly update and patch software to close vulnerabilities.
Authorities discourage paying ransoms, as it does not guarantee data recovery and may encourage further criminal activity.
