U.S. Senator Ron Wyden has called for an FTC investigation into Microsoft, citing serious cybersecurity negligence linked to ransomware attacks, particularly following a breach at Ascension Healthcare. Wyden’s concerns stem from a contractor’s inadvertent click on a malicious link leading to vulnerabilities in Microsoft’s software, specifically outdated encryption standards like RC4. He argues that Microsoft’s monopolization of operating systems exacerbates national security risks, as the company has not yet issued necessary updates or warnings about these vulnerabilities. While Microsoft acknowledges these concerns, it emphasizes a gradual approach to phasing out outdated standards to avoid disrupting customer systems.
