With the API information and his controlled execution flow, Alex started to reverse-engineer the VM logic. He applied his understanding of the VMProtect IR and translated the VM instructions back into a higher-level representation.

The VM is custom-built, and I assure you that it's unbreakable. You'll need to dig deep and think outside the box. Good luck!

Alex began by running the executable in a sandbox environment, observing its behavior, and collecting basic information. The VMProtect wrapper was evident, wrapping the original code in a virtual machine. He identified the VMProtect version and noted its configuration.

I've heard about your exceptional skills in reverse engineering. I'm willing to put your expertise to the test. Attached is a VMProtect-encrypted executable. Your task is to crack the protection and reveal the secrets within.

Alex crafted a custom fuzzer to feed malformed input to the VM, attempting to trigger the OOPS. After several iterations, he succeeded in redirecting the dispatcher to a controlled location.

Alex's curiosity was piqued. He had worked with VMProtect before, but never encountered a case that seemed "unbreakable." He downloaded the attachment, a 2MB executable file named mystery.vmexe . The file was encrypted with VMProtect, a popular virtual machine-based protector that made analysis notoriously difficult.
