{"success":true,"data":{"ext":"mui","name":"MUI","description":"Multilingual User Interface (MUI) files are Windows language resource modules developed and maintained by Microsoft. They provide localized strings, images, and other interface resources for system components and applications, enabling the same program to display different languages without changing the core executable. Because MUI files are executable-format containers, they should be obtained from trusted sources, although the format itself is generally used for safe localization rather than active code.","mime":[],"risk_level":"Safe","signatures":[{"hex":"4D 5A","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]}],"related":[],"usage":{"python":"def is_mui(file_path: str) -> bool:\n    \"\"\"Check if file is a valid MUI by magic bytes.\"\"\"\n    signature = bytes([0x4D, 0x5A])\n    with open(file_path, \"rb\") as f:\n        return f.read(2) == signature","node":"function isMUI(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x4D, 0x5A]);\n  return buffer.subarray(0, 2).equals(signature);\n}","go":"func IsMUI(data []byte) bool {\n    signature := []byte{0x4D, 0x5A}\n    if len(data) < 2 {\n        return false\n    }\n    return bytes.Equal(data[:2], signature)\n}"}}}
