Volt Typhoon Targets U.S. Critical Infrastructure Amid Surge in Ransomware

On February 6, 2024, the Cybersecurity and Infrastructure Security Agency (CISA), along with the FBI and NSA, issued a dire warning about state-sponsored cyber actors from China, known as Volt Typhoon. These attackers have gained persistent access to critical infrastructure systems in the U.S., particularly within the communication and energy sectors. Organizations are urged to patch vulnerabilities frequently exploited by such actors to mitigate risks. This alert comes alongside a severe ransomware attack affecting Lurie Children's Hospital, which had to take its systems offline due to demands from the Rhysida group, severely impacting essential medical services. Furthermore, February has unveiled multiple new vulnerabilities, including CVE-2024-21762 affecting Fortinet FortiOS, posing a remote code execution risk, and urgent patches from Microsoft addressing critical issues in Outlook. These incidents highlight the escalating threats in the cyber landscape and the critical need for robust defenses.
