Vm Detection Bypass -

VBoxManage setextradata "VM_Name" "VBoxInternal/Devices/pcbios/0/Config/DmiSystemProduct" "MyProduct"
VBoxManage setextradata "VM_Name" "VBoxInternal/Devices/pcbios/0/Config/DmiSystemVendor" "Dell Inc."
VBoxManage setextradata "VM_Name" "VBoxInternal/Devices/pcbios/0/Config/DmiSystemVersion" "OptiPlex 7020"

Customize DMI/SMBIOS strings to mimic a real OEM (Dell, Lenovo, HP). Also change the VirtualBox device IDs in VBoxManage.

Use a hypervisor-level hook. With KVM or Hyper-V: vm detection bypass

# Example using KVM CPUID masking
echo 1 > /sys/module/kvm/parameters/ignore_msrs
# Mask hypervisor bit in CPUID
qemu-system-x86_64 -cpu host,-hypervisor

For Windows sandboxes, Hyper-V with -vmx flag hides the hypervisor bit from cpuid. Customize DMI/SMBIOS strings to mimic a real OEM

PCI passthrough – Assign physical GPU, NIC, or USB controller directly to the VM. This removes most device-based fingerprints. For Windows sandboxes, Hyper-V with -vmx flag hides

Nested virtualization – Run your VM inside another VM (e.g., VMware inside Hyper-V) – malware often checks only one layer.

Custom firmware – Replace UEFI/BIOS with OVMF patched to remove BOCHS or QEMU strings.

Get-WmiObject -Class Win32_ComputerSystem | Select-Object Manufacturer, Model

Output like "VMware Virtual Platform" triggers detection.
