{"success":true,"data":{"ext":"arf","name":"Webex Advanced Recording Format files","description":"Webex Advanced Recording Format (ARF) is a proprietary recording file format developed and maintained by Cisco Webex for capturing online meeting sessions. It stores audio, video, chat, and screen-sharing data from meetings, webinars, and training sessions, and is opened with Webex tools. The format is generally considered safe, but older recordings may need Cisco-supported software, and access can be limited if Webex is no longer available.","mime":[],"risk_level":"Safe","signatures":[{"hex":"01 00 02 00","offset":0,"sources":[{"name":"Gary Kessler","url":"https://www.garykessler.net/library/file_sigs_GCK_latest.html"}]}],"related":[],"usage":{"python":"def is_arf(file_path: str) -> bool:\n    \"\"\"Check if file is a valid ARF by magic bytes.\"\"\"\n    signature = bytes([0x01, 0x00, 0x02, 0x00])\n    with open(file_path, \"rb\") as f:\n        return f.read(4) == signature","node":"function isARF(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x01, 0x00, 0x02, 0x00]);\n  return buffer.subarray(0, 4).equals(signature);\n}","go":"func IsARF(data []byte) bool {\n    signature := []byte{0x01, 0x00, 0x02, 0x00}\n    if len(data) < 4 {\n        return false\n    }\n    return bytes.Equal(data[:4], signature)\n}"}}}
