Uptick in healthcare organizations experiencing targeted DDoS attacks

Healthcare organizations worldwide have been targeted by pro-Russian hacktivist group Killnet, prompting an increase in requests for assistance mitigating these types of attacks. The rise in political tensions and the conflict in Ukraine have contributed to this growing cybersecurity threat landscape. Distributed-denial-of-Service (DDoS) attacks do not require intrusion or a foothold in the target network, making them more accessible than ever before. While Cloudflare has been automatically detecting and mitigating these attacks on behalf of its customers, additional precautionary measures are recommended to improve security posture, including enabling adaptive DDoS protection, deploying firewall rules, and caching as much data as possible. Defenders who leverage automated defenses have a significant advantage over those who do not.
