Wallet-Draining npm Package Impersonates Nodemailer to Hijack Crypto Transactions
Malicious npm package impersonates Nodemailer and drains wallets by hijacking crypto transactions across multiple blockchains.

Advanced tools
You use node.js for speed? You process XML streams? Then you want the fastest XML parser: libexpat!
A stupid speed test is supplied in bench.js
. We measure how many
25-byte elements a SAX parser can process:
These numbers were recorded on a Core 2 2400 MHz.
Install node-expat:
npm i node-expat
Important events emitted by a parser:
(function () {
"use strict";
var expat = require('node-expat')
, parser
;
parser = new expat.Parser("UTF-8");
parser.on('startElement', function (name, attrs) {
console.log(name, attrs);
});
parser.on('endElement', function (name) {
console.log(name);
});
parser.on('text', function (text) {
console.log(text);
});
parser.on('error', function (err) {
console.error(err);
});
parser.write("<html><head><title>Hello World</title></head><body><p>Foobar</p></body></html>");
}());
Use test.js
for reference.
#on('startElement' function (name, attrs) {})
#on('endElement' function (name) {})
#on('text' function (text) {})
#on('processingInstruction', function (target, data) {})
#on('comment', function (s) {})
#on('xmlDecl', function (version, encoding, standalone) {})
#on('startCdata', function () {})
#on('startCdata', function () {})
#on('endCdata', function () {})
#on('entityDecl', function (entityName, isParameterEntity, value, base, systemId, publicId, notationName) {})
#on('error', function (e) {})
#stop()
pauses#resume()
resumesWe don't emit an error event because libexpat doesn't use a callback
either. Instead, check that parse()
returns true
. A descriptive
string can be obtained via getError()
to provide user feedback.
Alternatively, use the Parser like a node Stream. write()
will emit
error events.
A word about special parsing of xmlns: this is not neccessary in a bare SAX parser like this, given that the DOM replacement you are using (if any) is not relevant to the parser.
