Hackers take advantage of Microsoft security flaw, global businesses and agencies at risk

Hackers took advantage of a security flaw in a popular Microsoft server software, with analysts warning of widespread cybersecurity breaches in the US and beyond. The zero-day exploit (meaning, the developer has only learned of the flaw, earlier unknown, and has zero days to fix it) has placed thousands of on-premises servers used by global businesses and agencies at risk. (On-premise server is a physical, on-site server that a company or agency needs to manage and maintain.)
