Esxcli Allow Unverified Binaries Execution

Swachchhanda Shrawan Poudel (Nextron Systems)

Detects modification of the execInstalledOnly setting on ESXi hosts to allow execution of non-VIB (unverified) binaries. This technique is often used by attackers to run custom tools or other implants directly on ESXi hypervisors without the need for VIB signing, which can facilitate further compromise or persistence on the host.
