Custom VMs usually implement basic operations. You must map the hex values in the .anom file to their logic:
: Jumps (JZ, JNZ) that decide if your input is correct. Memory : Loading from a "stack" or specific registers. 3. Trace the Execution Once the opcodes are understood, trace the bytecode: Epic_VM.anom
: Epic_VM.anom is the binary or bytecode file executed by the custom VM engine. 🛠️ Investigation Steps 1. Identify the Architecture Custom VMs usually implement basic operations
📌 : If this is from a specific platform like HackTheBox or a recent CTF, look for the "dispatcher" function—it is the heart of the VM where all logic is processed. Identify the Architecture 📌 : If this is
First, determine if you have the VM runner (the "emulator") or just the bytecode.
: Look for a specific point where your input is compared against a hardcoded (but encrypted) string. 💡 Key Insights for Solving
: Write a small Python script to "disassemble" the .anom file into human-readable assembly.
