An obfuscator transforms readable code into a complex, mangled version that still runs perfectly but is nearly impossible for a human to follow. A deobfuscator reverses this by: Beautifying the layout (fixing indentation and spacing).

To build a "solid" feature for a portable JavaScript deobfuscator and unpacker, you should focus on a multi-layered architectural approach that balances deep static analysis with safe execution. High-performance tools like js-deobfuscator on Rust and established projects like de4js provide a blueprint for these features. Core Feature Set for a Solid Deobfuscator

A JavaScript deobfuscator is a tool that takes obfuscated JavaScript code and converts it back into a more readable and understandable format. Deobfuscation can help developers:

2. Background & Related Work

2.1 Obfuscation Taxonomies

Xu et al. (2020) classify JS obfuscation into lexical (renaming, encoding), data (string splitting, array rotation), and control-flow categories. Packers like UglifyJS and javascript-obfuscator are widely used, while malware often employs custom packers with nested eval and Function constructors. Implementation JSDeob-Port is written in 2,800 LOC of

String and Array Unpacking: Recovers literals hidden within complex array structures or encoded strings (e.g., Base64 or Unicode) and replaces the obfuscated references with their original values.
