Data Theft Repackaged: A Case Study in Malicious Wrapper Packages on npm
The Socket Research Team breaks down a malicious wrapper package that uses obfuscation to harvest credentials and exfiltrate sensitive data.
music-metadata
Advanced tools
The music-metadata npm package is a powerful tool for parsing and extracting metadata from audio files. It supports a wide range of audio formats and provides detailed information about the audio file, including tags, format, and technical properties.
Extract Basic Metadata
This feature allows you to extract basic metadata from an audio file, such as title, artist, album, and genre. The code sample demonstrates how to use the `parseFile` method to read and log metadata from an MP3 file.
const mm = require('music-metadata');
const fs = require('fs');
async function getMetadata(filePath) {
try {
const metadata = await mm.parseFile(filePath);
console.log(metadata);
} catch (error) {
console.error(error.message);
}
}
getMetadata('path/to/audio/file.mp3');
Extract Format Information
This feature allows you to extract format information from an audio file, such as the container type, codec, sample rate, and bit rate. The code sample demonstrates how to use the `parseFile` method to read and log format information from an MP3 file.
const mm = require('music-metadata');
const fs = require('fs');
async function getFormatInfo(filePath) {
try {
const metadata = await mm.parseFile(filePath);
console.log(metadata.format);
} catch (error) {
console.error(error.message);
}
}
getFormatInfo('path/to/audio/file.mp3');
Extract Technical Properties
This feature allows you to extract technical properties from an audio file, such as duration, number of channels, and bit depth. The code sample demonstrates how to use the `parseFile` method to read and log technical properties from an MP3 file.
const mm = require('music-metadata');
const fs = require('fs');
async function getTechnicalProperties(filePath) {
try {
const metadata = await mm.parseFile(filePath);
console.log(metadata.common);
} catch (error) {
console.error(error.message);
}
}
getTechnicalProperties('path/to/audio/file.mp3');
The node-id3 package is focused on reading and writing ID3 tags in MP3 files. It provides a simpler interface for handling ID3 tags compared to music-metadata, but it is limited to MP3 files and does not support other audio formats.
The musicmetadata package is another tool for extracting metadata from audio files. It supports a variety of audio formats and provides similar functionality to music-metadata. However, it is less actively maintained and may not support the latest audio formats and tags.
The id3js package is a JavaScript library for reading ID3 tags from MP3 files. It is designed to work in both Node.js and browser environments. While it offers similar functionality to music-metadata for MP3 files, it does not support other audio formats.

duration
: default: false
, if set to true
, it will parse the whole media file if required to determine the duration.native
: default: false
, if set to true
, it will return native tags in addition to the common
tags.skipCovers
: default: false
, if set to true
, it will not return embedded cover-art (images).var mm = require('music-metadata');
const util = require('util')
mm.parseFile('../test/samples/Mu' +
'sicBrainz-multiartist [id3v2.4].V2.mp3', {native: true})
.then(function (metadata) {
console.log(util.inspect(metadata, { showHidden: false, depth: null }));
})
.catch(function (err) {
console.error(err.message);
});
import * as mm from 'music-metadata';
import * as util from 'util';
mm.parseFile('../test/samples/MusicBrainz-multiartist [id3v2.4].V2.mp3')
.then((metadata) => {
console.log(util.inspect(metadata, {showHidden: false, depth: null}));
})
.catch((err) => {
console.error(err.message);
});
Although in most cases duration is included, in some cases it requires music-metadata
parsing the entire file.
To enforce parsing the entire file if needed you should set duration
to true
.
mm.parseFile('sample.mp3', {duration: true})
.then(function (metadata) {
console.log(util.inspect(metadata, { showHidden: false, depth: null }));
})
For a live example see parse MP3 (ID3v2.4 tags) stream with music-metadata, hosted on RunKit.
In order to read the duration of a stream (with the exception of file streams), in some cases you should pass the size of the file in bytes.
mm.parseStream(someReadStream, 'audio/mpeg', { duration: true, fileSize: 26838 })
.then( function (metadata) {
console.log(util.inspect(metadata, { showHidden: false, depth: null }));
someReadStream.close();
});
