Represents a literal constant value.

Opaque expression stored as raw AST source (for complex exprs like listcomps).

Custom exception for API errors with structured information.

Unconditional jump to a block

target = value

Represents a literal constant value.

target = left op right

target = slice(lower, upper, step)

Removes module-level function definitions that are never called. A function is dead if its name never appears as a Load Name in the module,

target = obj[key]

Represents a named variable or register.

Substitute zero-arg function calls with their known constant return values.

target = value

target = v1 op v2 op ... (and/or)

Conditional jump

Base HTTP client for de4py backend API. Features: - Automatic User-Agent header with version - Configurable timeout

Remove module-level class definitions that are never referenced.

Converts eval(b'identifier') or X.eval(b'identifier') → Name('identifier'). Pattern used in test_obf.py to dynamically access builtins:

target = obj.attr

obj[key] = value

obj.attr = value

Represents a named variable or register.

Extracted opcode table from a VM class.

Propagates module-level constant variable assignments. Pattern: x = 'some_constant' ← assignment from a Constant func(x

target = (elts...)

Resolves builtins-dict subscript pattern used in style-2 obfuscation. Detects the variable holding globals()['__builtins__'] (or __dict__)

Resolves builtins-dict subscript pattern used in style-2 obfuscation. Pattern: x = __builtins__ (or via isinstance+__dict__ guard)

Control Flow Graph representing a function or code block.

target = func(*args, **kwargs)

target = func(*args)

Console handler that colorizes log output by severity level.

target = left op right (comparison)

Combines all AST-based string transformations into a single pass.

Bottom-up constant folder. Folds any expression whose value is statically determinable using the safe environment (b64/b85 decode, chr/or

Evaluates for-loops where all referenced data is constant and the body calls exec() with a computed payload. Universal pattern: for

Advanced environment and integrity tester for de4py.

Removes unused constant-value assignments in function/method bodies. Pattern: def f(x): _unused = 746 ← assigned but n

Handles the pattern: eval(b'exec')(payload) → exec(payload) and: eval('exec')(payload) → exec(payload) Common in test_ob
