VMProfiler CLI - VMProtect 2 Virtual Machine Information Displayer

vmprofiler-cli is a CLI program which displays all details of a specified VMProtect 2 virtual machine. This information includes virtual instruction pointer advancment direction, all vm handlers, virtual instruction rva decrypt instructions, vm handler table entry decrypt instruction, and much more.

usage

Usage: vmprofiler-cli [options...]
Options:
    --bin, --vmpbin        unpacked binary protected with VMProtect 2 (Required)
    --vmentry, --entry     rva to push prior to a vm_entry (Required)
    --showhandlers         show all vm handlers...
    -h, --help             Shows this page
