: Addition, Subtraction, XOR (often used for obfuscation).
📌 : 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.
: Reverse the bytecode runner to understand how it processes data. Epic_VM.anom
: Use strings or a hex editor to look for magic bytes or custom opcodes.
: Most .anom challenges use a loop to XOR your input with a key stored in the bytecode. : Addition, Subtraction, XOR (often used for obfuscation)
Custom VMs usually implement basic operations. You must map the hex values in the .anom file to their logic:
: Look for a specific point where your input is compared against a hardcoded (but encrypted) string. 💡 Key Insights for Solving : Use strings or a hex editor to
The "Epic_VM" series involves a custom-built virtual machine architecture. Instead of standard x86 or ARM assembly, you are given a proprietary instruction set.
