Recursive vs Linear JSVM Disassembly
a day ago
- Linear disassembly works by decoding every opcode in bytecode sequentially, suitable for simple VMs without runtime changes.
- Recursive disassembly follows jumps and conditionals, necessary for VMs that modify opcode IDs or encryption at runtime.
- Google/Botguard uses runtime opcode changes and anti-debug features, requiring recursive disassembly and making linear approaches ineffective.
