Senator Wyden Urges FTC Probe of Microsoft Ransomware Lapses
🔍 Senator Ron Wyden has asked the Federal Trade Commission to investigate Microsoft for what he describes as "gross cybersecurity negligence" that he says facilitated ransomware attacks on U.S. critical infrastructure, including healthcare. Wyden's four-page letter to FTC Chair Andrew Ferguson cites the 2024 Ascension breach attributed to Black Basta and details an attack chain that began when a contractor clicked a malicious link after using Microsoft's Bing search. The senator highlights exploitation of insecure default Kerberos settings and legacy RC4 support enabling Kerberoasting, and criticizes Microsoft for not enforcing stronger defaults and minimum password requirements while noting the company's published mitigations and planned deprecations.
