VMware is patching a set of severe “sandbox escape” bugs. out of 10, and even VMware’s flagship ESXi hypervisor is affected. A new Bifrost remote access trojan (RAT) for Linux employs a number of techniques to remain hidden, including using a “VMware-esque” domain name for command and control servers.
