As a result, it is sometimes possible to detect virtualization or sandboxing by examining the number of CPUs on the system. …
CPUID Sandbox Evasion
The CPUID instruction is a low-level command that allows you to retrieve information about the CPU that is currently running. This instruction, which is executed at the CPU level (using the bytecode 0FA2), is available on all processors that are based on the Pentium architecture or newer.
You can use the CPUID instruction to retrieve various pieces of information …
VMCPUID Sandbox Evasion
The VMCPUID instruction is a sophisticated mechanism often employed by malware to ascertain if it is operating within a virtual environment.
This instruction is part of the x86 architecture's virtual machine extensions (VMX) and is designed to provide information about the capabilities and status of the virtual machine.
By using VMCPUID, malware can adapt its behavior based on …
