Quasar RAT Disguised as an npm Package for Detecting Vulnerabilities in Ethereum Smart Contracts
Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
eiows is a replacement module for ws which allows, but doesn't guarantee, significant performance and memory-usage improvements. This module is specifically only compatible with Node.js. This package is mainly meant for projects which depend on the performance of the “original uws package”. This package requires engine.io(3.4.2 or higher) and it should work on Node 16, 18, 20, 22. Git should be installed on the system to build and compile the module. This module only runs on Linux/FreeBSD/MacOS.
Installation:
npm install eiows
or
yarn add eiows
Examples:
// ESM
import * as http from 'http';
import { Server } from "socket.io";
import eiows from 'eiows';
let server = http.createServer();
let io = new Server(server, {
wsEngine: eiows.Server,
perMessageDeflate: {
threshold: 32768
}
});
io.on("connection", () => {
console.log('Yes, you did it!');
});
server.listen(8080);
// CJS
var http = require('http');
var server = http.createServer();
var io = require("socket.io")(server, {
wsEngine: require("eiows").Server,
perMessageDeflate: {
threshold: 32768
}
});
io.on("connection", function(socket) {
console.log('Yes, you did it!');
});
server.listen(8080);
Have fun!
