"Confidential VMs Hacked via New Ahoi Attacks"
A team of researchers from ETH Zurich detailed a new type of attack that can compromise Confidential Virtual Machines (CVMs). They presented two variations of what they refer to as "Ahoi attacks." One of them, called "Heckler," involves a malicious hypervisor injecting interrupts to change data and control flow, which compromises CVMs' integrity and confidentiality.
