Senator Ron Wyden has criticized Microsoft for delivering "dangerous, insecure software" that contributed to a ransomware attack on Ascension, a major hospital network, and has urged the FTC to investigate the company's cybersecurity practices. Wyden highlighted longstanding vulnerabilities, particularly the use of the outdated RC4 encryption algorithm, and accused Microsoft of prioritizing profits over security while failing to provide adequate protections for its users. He argues that Microsoft's dominance in the enterprise operating system market poses a significant national security risk due to its negligence in addressing these issues.
