U.S. Senator Ron Wyden has urged the Federal Trade Commission to investigate Microsoft for alleged cybersecurity negligence, linking the company’s practices to significant ransomware attacks on critical infrastructure, including healthcare organizations. Wyden criticized Microsoft’s default configurations and outdated encryption technologies, asserting these practices threaten U.S. national security. A Microsoft spokesperson countered that while RC4 encryption is being phased out, its complete removal could disrupt customer systems. This incident highlights the ongoing concern over cybersecurity vulnerabilities within major tech companies and the need for robust security measures to protect sensitive data and infrastructure.
