vm-and-bytecode-reverse

To reverse engineer custom VM bytecode, you need to analyze the bytecode interpreter to identify dispatchers, map opcodes to operations, and reconstruct the instruction set architecture to generate a readable disassembly.

A bytecode dispatcher routes execution to opcode handlers and can be a switch statement, a dispatch table, or an indirect call. Identifying the dispatcher type is necessary to map opcodes and reconstruct the ISA accurately.

You build a disassembler for a custom ISA by providing a bytecode sample and any accompanying data to map opcodes to their underlying operations, generating a readable disassembly and opcode map.

Yes, bytecode reverse engineering applies to malware analysis and security research by documenting custom virtual machine interpreters to reveal underlying logic and reconstruct hidden operations.

You need to provide a VM bytecode sample and any accompanying data required to map opcodes, reconstruct the instruction set architecture, and generate a functional disassembler.
