It is used to store logical acquisitions, case data, and related forensic evidence for review, analysis, and long-term investigation workflows. The format is primarily historical and remains relevant in legacy forensic archives; files should be handled carefully to preserve chain of custody and verify integrity.","mime":[],"risk_level":"Safe","signatures":[{"hex":"4C 45 46 32 0D 0A 82 00","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":[],"usage":{"python":"def is_lxnn(file_path: str) -> bool:\n    \"\"\"Check if file is a valid LXNN by magic bytes.\"\"\"\n    signature = bytes([0x4C, 0x45, 0x46, 0x32, 0x0D, 0x0A, 0x82, 0x00])\n    with open(file_path, \"rb\") as f:\n        return f.read(8) == signature","node":"function isLXNN(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x4C, 0x45, 0x46, 0x32, 0x0D, 0x0A, 0x82, 0x00]);\n  return buffer.subarray(0, 8).equals(signature);\n}","go":"func IsLXNN(data []byte) bool {\n    signature := []byte{0x4C, 0x45, 0x46, 0x32, 0x0D, 0x0A, 0x82, 0x00}\n    if len(data) < 8 {\n        return false\n    }\n    return bytes.Equal(data[:8], signature)\n}"}}}
