US senator Ron Wyden has written a letter to the FTC requesting that the organisation investigate Microsoft for what he calls "gross cybersecurity negligence." His complaint is primarily related to a form of encryption still supported by the company's Windows operating system, which the senator's office believes is vulnerable to ransomware attacks.
In the letter [PDF warning], Senator Wyden reveals that an investigation his office conducted into a ransomware breach of healthcare provide Ascension last year found that support of the RC4 encryption cipher was a direct contributor to the attack (via Ars Technica).
