Cybersecurity Briefing: March 6, 2022 - Ongoing Ransomware Threats

Lead Story: Ransomware Threats Intensify

On March 6, 2022, ransomware attacks continue to pose significant risks, particularly for healthcare organizations. As the digital landscape shifts under the pressures of the ongoing pandemic and geopolitical tensions, healthcare systems find themselves increasingly vulnerable to sophisticated attacks. Cybercriminals are leveraging ransomware as a tool not only for financial gain but also as a means to exploit the operational stresses caused by the pandemic response. This situation underscores the urgent need for robust cybersecurity measures and encourages organizations to prioritize incident response protocols and employee training to mitigate risks.

Secondary Item 1: Exploits of Older Vulnerabilities

Cyber actors are increasingly targeting older software vulnerabilities rather than focusing on newly discovered ones. This trend, highlighted by CISA, indicates a dangerous reliance on unpatched systems accessible via the internet. Organizations are urged to conduct thorough assessments of their software environments to ensure that all known vulnerabilities are addressed promptly. CISA Advisory

Secondary Item 2: Mailto-URLs Exploit
