The target was Seraphim, a proprietary corporate espionage tool used by a shadowy private military contractor. It was protected by VMProtect, a name that struck fear into the hearts of casual crackers. VMProtect wasn’t just a packer; it was a virtualization engine. It took the native x86 code of the application, digested it, and regurgitated it as a custom, fictional bytecode that ran on a virtual CPU embedded within the binary itself.
