The company is further recommending users to upgrade to the latest available supported releases of vSphere components to mitigate known issues and  disable the OpenSLP service  in ESXi. "In 2021, ESXi 7.0 U2c and ESXi 8.0 GA began shipping with the service disabled by default," VMware added. The announcement comes as unpatched and unsecured VMware ESXi servers around the world have been targeted in a  large-scale   ransomware campaign  dubbed ESXiArgs by likely exploiting a two-ye...
