The Shadow Brokers are selling what appears to be a zero-day Windows exploit kit for $600,000 online. The exploit may target the Server Message Block (SMB) function on Windows machines and permit the compromise of sensitive information. The U.S. Computer Emergency Readiness Team (US-CERT) has issued a warning for users to update their Windows install. So far, theres no confirmation of any SMB vulnerability in Windows, and Microsoft has no reports of unpatched vulnerabilities in the wild.”]
