1. Italy warns massive ransomware attack targeting servers in Europe, U.S.

Italy's National Cybersecurity Agency (ACN) warned Sunday that a large-scale ransomware attack had targeted thousands of computer servers across Europe, the United States, and Canada. The attack targets known vulnerabilities in VMware ESXi technology that had not been fully patched. "These types of servers had been targeted by hackers in the past due to their vulnerability," according to ACN. "However, this vulnerability of the server was not completely fixed, leaving an open door to hackers for new attacks." Experts estimate that thousands of computer servers have been breached, and more are expected to be compromised as the attack continues.
