An interactive lab for understanding VM-based binary obfuscation, one step at a time.
Check it out live here: https://0x90sh.github.io/vm-workbench/
Step through a virtual machine's internals, watch a program get interpreted opcode by opcode, and see where the anti-reverse-engineering strength actually comes from: complexity.
VM-based obfuscation (virtualization) is one of the strongest software-protection techniques in the wild. Instead of shipping native machine code, a protector compiles the original routine into bytecode for a custom, secret instruction set, then bundles a tiny interpreter to run it. To reverse the program, an analyst first has to reverse the machine.
That sounds impenetrable, but it isn't magic. The protection is complexity, not secrecy. Every design choice a protector makes adds modeled recovery work for the analyst, and every choice also carries a performance cost. VM Workbench makes that trade-off visible, tunable, and comparable.
Check it out on github!
