Google said today it worked with industry partners to dismantle a botnet made up of more than 1.3 million Android TV set-top boxes that ship with malicious software which secretly rents the user's Internet connection out to strangers and conducts advertising fraud. Experts involved in the takedown say the action is likely to sever the botnet's access to more than 10 million additional compromised systems, including other Internet of Things (IoT) products such as Android-based healthcare devices and karaoke machines.

Two attacks made public this week allow a malicious host to read data inside AMD SEV-SNP-protected virtual machines (VMs), which are built to keep the server's operator out. One of them, Mior, can also modify a VM's memory and fake the signed report confirming which software it runs. Both need control of the server's hypervisor, and Mior also needs control of the server's BIOS. Researchers

That kind of scenario raises a response question: what does “stop the agent” actually mean? A
