Microsoft will patch Windows 10 after the NSA quietly told it about a major vulnerability

▤ Summary

The National Security Agency alerted Microsoft in recent weeks to a significant issue affecting its Windows 10 operating system, ubiquitous within corporations and among consumers, two senior federal cybersecurity officials told CNBC. The flaw affected encryption of digital signatures used to authenticate content, including software or files. If exploited, the flaw could allow criminals to send malicious content with fake signatures that make it appear safe. In the past, the top security agency has kept some major vulnerabilities secret in order to use them as part of the U.S. tech arsenal. According to the Post, the NSA said in a Tuesday morning call with cybersecurity experts that Microsoft will report that it had not seen any exploitation of the flaw.
