Healthcare & Cybersecurity: From Emerging Threats to Strategic Responses: A Weekly Cybersecurity Roundup

Today's cybersecurity highlights include the emergence of "Rockstar 2FA," a phishing-as-a-service platform targeting Microsoft 365 users, and a critical zero-day vulnerability in Windows Server 2012 with unofficial patches issued. The Rhysida ransomware gang attacked Alder Hey Children's Hospital, risking sensitive data exposure, while Cabot faced a breach compromising 394,000 client files. Industry moves include major acquisitions by CrowdStrike, Cybereason, and others, emphasizing enhanced cloud and healthcare security. Meanwhile, a Russian influence operation leverages AI to target Ukraine and global narratives, ransomware groups recruit cybersecurity experts, and a data broker exposed 600,000 unprotected files, underscoring persistent vulnerabilities across sectors.
