Lua Virtualizer — Obfuscate, Virtualize & Protect Python Code

Lua Virtualizer is a tool to obfuscate, virtualize & protect Lua .lua scripts against reverse engineering with a VM engine (or finite-state automata machine), self-defending integrity checks, polymorphic string encryption, anti-debugging, anti-vm, anti-emulation and 50+ total obfuscation strategies!

Why Lua scripts need obfuscation?

Scripts are typically distributed as plain .lua files or bundled inside packages. That convenience means anyone with file access can read the full logic, hunt for credentials or API keys in strings, and steal your algorithms unless you take extra steps to hide intent.

Lua is one of the most popular general-purpose scripting languages. It is widely used for automation, backend services, data processing, tooling, and licensing/agent code that customers run on their own machines.

Obfuscation strategies

Lua Virtualizer comes with many advanced obfuscation, virtualization & protection strategies. You can easily tune protection versus size and performance.

Powerful obfuscation

Polymorphic string encryption is the core of the string pipeline: each build generates a fresh decryptor so literals never share one static algorithm. Integers, floats, and decoy noise join that layer. The result conceals literals and structure while preserving tested runtime behaviour.

Code virtualization

Code virtualization is the main control-flow defense. Selected statements are lifted into a randomly generated VM engine (or FSA / flattened dispatcher) with shuffled dispatch tables, decoy opcodes, and an obfuscated dispatcher loop. Analysts must interpret the virtual machine instead of reading plain Lua.

Finite-state automata (FSA)

Finite-state automata (FSA) obfuscation rewrites linear Lua statement blocks into dual-state automata with opaque schedulers and shuffled dispatch handlers. Instead of reading code top to bottom, analysts must follow numeric states, transition tables, and decoy paths to reconstruct the original order.

Anti-debugging

Anti-debugging protection inserts polymorphic probes that detect attached debuggers, tracing hooks, and related host signals, together with anti-VM, anti-sandbox and anti-emulator checks. When a check fires, the obfuscated script exits silently instead of revealing protected logic under interactive analysis.

Self-integrity checks

Self-defending integrity checks verify that the obfuscated file has not been patched. A bootstrap probe hashes the on-disk script and sets a tamper key when it no longer matches the obfuscated build. String decryptors consume that key, so edited scripts return garbage instead of plaintext.

Protection linker

The protection linker adds decoy functions and fake calls so a copied fragment still looks like real program code. Hidden traps fire only if someone edits the file or runs a piece of it on its own. When the script starts normally, those extras stay silent and the program runs as usual.

Before and after obfuscation

Look at this example — the same script becomes harder to read at a glance after obfuscation.

Sample Lua script before obfuscation

local function greet(name)
  print("Hello, " .. name)
end
greet("Lua")

After obfuscation

Would you still recognise the original intent if you only had the obfuscated text and no prior copy of the script?

How does Lua Virtualizer work?

The engine parses Lua source into an AST tree, then applies selectable transforms. Code virtualization (VM, FSA, or flattening) rewrites execution so analysts cannot read the script top to bottom. Polymorphic string encryption hides literals; self-defending integrity probes detect patched files. Also available: identifier renaming, numeric encryption, noise and decoy insertion, the protection linker, and anti-debugging checks. Many techniques are specific to this product; some ideas are shared with our other protection tools.

When all passes finish, the engine emits a new .lua file. Edge cases in the Lua grammar and hosting environments mean you should always test the output in your target runtime.

Lua dialect (target)

The client target property defaults to auto. When target is auto or empty, the SDK omits the POST field. Sending target=auto is also valid. Explicit values are 5.1, 5.2, 5.3, 5.4, 5.5, luajit, and luau.

Omitting target or sending auto detects the dialect by trying 5.1, then 5.2, 5.3, 5.4, 5.5, then Luau, and keeping the oldest that parses. LuaJIT is never inferred. A file whose only newer syntax is goto is detected as 5.2 because goto was introduced in Lua 5.2. Pass luajit when the script must be treated as LuaJIT. The JSON response field target is the dialect actually used.

Protect your Lua scripts & algorithms

Take no chances, use Lua Virtualizer to obfuscate, virtualize and protect your Lua scripts and algorithms.

Our company has a long history in obfuscation technologies and code obfuscators (see our PowerShell, Java, AutoIt, x86 Assembly & obfuscators).

We actively bugfix, research and develop new obfuscation strategies for our tools.

You can count on our expertise and support in this field.

Installation

The preferred way of WebApi interface installation is via pip.

Run:

pip install lua-virtualizer

or

python3 -m pip install lua-virtualizer

Per-function markers

Markers are source syntax, not a library import. There is no separate decorator package. The marker is the first statement of a function. The engine reads it and strips it.

local function f()
  LUAVIRTUALIZER(VM(RND), ENABLE(STRINGS), DISABLE(encrypt_strings))
  return 1
end

VM(...) selects the dispatcher for that function. ENABLE(...) replaces the function's strategy set with the named groups or strategies. DISABLE(...) then removes the named groups or strategies. Clauses apply as VM, then ENABLE, then DISABLE, whatever order they are written in. Names are case-insensitive. ENABLE(ALL) is the same set --all turns on (every strategy except the four probes). DISABLE(ALL) clears every strategy. FSA is accepted as an alias of FSM. self_defending and protection_linker are not decorator names. They stay script-wide.

decoy_functions, every BUCKET strategy, callback_registration_stubs, and the PROTECT probes are inserted once for the whole script. A function ENABLE or DISABLE does not turn those passes on or off. A VM(...) nested inside VM(NONE) stays native Lua.

Category	Name	Description
Virtualization	VM(VM)	A word is a permuted opcode plus A, B, C, and Bx. The encrypted blob is a read-only code image. The Lua 5.1 shell fetches __vll_code[pc] and calls __vll_hs[__vll_map[opcode]]. Four decoy handlers share the table. A jump stores an absolute program counter. Exactly one mode applies to a function.
Virtualization	VM(FSM)	Same compiler, blob, and handler table as VM(VM). The outer loop is shifted, and an opaque gate reads the virtual program counter before the live handler. FSA is an alias of FSM.
Virtualization	VM(WEAVE)	Same compiler and encrypted blob. Registers, constants, and instruction words share one table. Three superoperators cover load-and-arithmetic, compare-and-branch, and the call exit. A back-edge rewrites the words it will fetch again. Host calls are the only exit.
Virtualization	VM(FLAT)	Same compiler and handler table. The loop form is shifted again, and the opaque gate mixes the virtual program counter with the running checksum.
Virtualization	VM(RND)	Each run picks VM(VM), VM(FSM), or VM(WEAVE) for this function. VM(FLAT) is not in the draw. The same seed repeats the choice. Nested functions inherit it unless they set their own VM(...). A VM(RND) nested inside VM(NONE) stays native Lua.
Virtualization	VM(NONE)	Leave this function, and every function nested inside it, as ordinary Lua.
Group	NAMES	rename_variables, rename_parameters, rename_functions, rename_function_calls, resolve_constants.
Group	STRINGS	split_strings, modify_strings, string_char_array_vault, encrypt_strings, array_string_crypt.
Group	NUMBERS	integers_to_arrays, floats_to_arrays, affine_integer_mask, encrypt_integers, integers_to_floating, encrypt_floating, mba_binops, array_int_crypt, array_char_crypt, array_double_crypt.
Group	BOOLEANS	complexify_booleans, insert_ternary_operators.
Group	SHAPE	decoy_functions, lambda_decoys, insert_dead_code, opaque_branches, opaque_mixer_chain, try_finally_noise, literal_padding, fake_import_markers, shuffle_functions. decoy_functions is inserted for the whole script.
Group	BUCKET	insert_random_value_bucket, random_bucket_integers, random_bucket_arrays, random_bucket_functions, random_bucket_characters, random_bucket_anti_regex, random_bucket_autostart. Inserted for the whole script.
Group	CALLS	dynamic_getattr_calls, obfuscate_imports, callback_registration_stubs. callback_registration_stubs is inserted for the whole script.
Group	COMMENTS	remove_comments.
Group	PROTECT	detect_debugger, anti_vm, anti_sandbox, anti_emulator. Inserted for the whole script. A positive detection ends the process with no error message.
Group	ALL	ENABLE(ALL) selects every strategy except the four probes. DISABLE(ALL) clears every strategy, including the probes.
Strategy	rename_variables	NAMES. Local and global variables become random identifiers. Every reference updates together, and scope rules stay intact.
Strategy	rename_parameters	NAMES. Parameter names and in-body bindings are rewritten to opaque tokens.
Strategy	rename_functions	NAMES. Function definitions are renamed and calls are retargeted. Metamethods such as __index and built-in library functions stay untouched.
Strategy	rename_function_calls	NAMES. Direct call sites look up the target through a name table instead of the literal identifier.
Strategy	resolve_constants	NAMES. Module-level constants are inlined at every use, and unused declarations are removed.
Strategy	split_strings	STRINGS. Literals are split into chunks and joined at runtime, so the whole token is no longer in one place.
Strategy	modify_strings	STRINGS. Literals are rewritten as shifted characters and rebuilt by a small runtime transform.
Strategy	string_char_array_vault	STRINGS. Strings are rebuilt from numeric character codes instead of quoted text.
Strategy	encrypt_strings	STRINGS. Each run emits a unique per-string decryptor. Two outputs do not share the same algorithm shape.
Strategy	array_string_crypt	STRINGS. String table elements are encrypted independently and rebuilt on demand.
Strategy	integers_to_arrays	NUMBERS. Integers are stored in tables and read by index, with decoy entries mixed in.
Strategy	floats_to_arrays	NUMBERS. Floats are lifted into table slots, with decoy values mixed in.
Strategy	affine_integer_mask	NUMBERS. Reversible bit masks wrap integers without changing the result. The helper matches the selected dialect.
Strategy	encrypt_integers	NUMBERS. Plain integers become equivalent arithmetic or bitwise expressions.
Strategy	integers_to_floating	NUMBERS. Whole numbers are reconstructed from math expressions and cast back with math.floor.
Strategy	encrypt_floating	NUMBERS. Floating-point literals become equivalent math expressions.
Strategy	mba_binops	NUMBERS. Binary operators are replaced with mixed boolean-arithmetic identities.
Strategy	array_int_crypt	NUMBERS. Integer table contents are stored encrypted and decoded at runtime.
Strategy	array_char_crypt	NUMBERS. Character table literals are stored encrypted and restored by generated decoder code.
Strategy	array_double_crypt	NUMBERS. Float table constants are hidden as encoded bit patterns and reconstructed while the program runs.
Strategy	complexify_booleans	BOOLEANS. Simple true/false tests are rewritten into longer equivalent conditions.
Strategy	insert_ternary_operators	BOOLEANS. Simple branches collapse into and/or conditional expressions.
Strategy	decoy_functions	SHAPE. Plausible functions that are never called. Inserted for the whole script.
Strategy	lambda_decoys	SHAPE. Unused anonymous functions near the top of the script. They are never called.
Strategy	insert_dead_code	SHAPE. Statements under opaque never-true conditions. The result of the script stays the same.
Strategy	opaque_branches	SHAPE. Always-false branches that look like real control flow.
Strategy	opaque_mixer_chain	SHAPE. Mixer functions and guards that never change the returned value.
Strategy	try_finally_noise	SHAPE. Lua has no try/finally, so the pass emits an inert pcall plus cleanup.
Strategy	literal_padding	SHAPE. A bulky string constant that live logic never reads. It shifts line numbers and inflates the file.
Strategy	fake_import_markers	SHAPE. Comments that mimic extra require calls. remove_comments deletes them.
Strategy	shuffle_functions	SHAPE. Permutes top-level function definitions when the execution order stays valid.
Strategy	insert_random_value_bucket	BUCKET. Enables the module-level decoy pools. Inserted for the whole script.
Strategy	random_bucket_integers	BUCKET. Unused integer decoys in the pool. Inserted for the whole script.
Strategy	random_bucket_arrays	BUCKET. Unused table decoys in the pool. Inserted for the whole script.
Strategy	random_bucket_functions	BUCKET. Unused function decoys in the pool. Inserted for the whole script.
Strategy	random_bucket_characters	BUCKET. Unused character decoys in the pool. Inserted for the whole script.
Strategy	random_bucket_anti_regex	BUCKET. Regex-shaped decoy literals. Inserted for the whole script.
Strategy	random_bucket_autostart	BUCKET. Decoy strings that resemble autostart paths and are never used by live code. Inserted for the whole script.
Strategy	dynamic_getattr_calls	CALLS. Call targets are built from fragments and resolved through a table lookup.
Strategy	obfuscate_imports	CALLS. require is rewritten so the module name is built at runtime. Those strings stay available for later string encryption.
Strategy	callback_registration_stubs	CALLS. Snippets that resemble callback registration and never wire an event source. Inserted for the whole script.
Strategy	remove_comments	COMMENTS. Removes -- comments from the emitted script.
Strategy	detect_debugger	PROTECT. Detects a debugger attached to the process (debug.gethook(), and IsDebuggerPresent on Windows). Inserted for the whole script. A positive detection ends the process with no error message.
Strategy	anti_vm	PROTECT. Detects VMware, VirtualBox, Parallels, KVM, and Linux DMI product or vendor strings. Inserted for the whole script.
Strategy	anti_sandbox	PROTECT. Detects a very low CPU count, Sandboxie, Joe Sandbox, and analysis-host tokens. Inserted for the whole script.
Strategy	anti_emulator	PROTECT. Detects WINE, Bochs, QEMU, XEN, and a short timing self-check. Inserted for the whole script.
