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.
Simple IPC library
This requires a bridge to connect all nodes. The bridge can reside in any process.
Client:Node Server:Bridge
IPC Transports: Unix Socket TCP
Server should be able to connect on a stateless manner, we have a Unix socket path, and if the file is there, we move on. Else we make new connection.

I suggest you clean up on start. When you get EADDRINUSE, try to connect to the socket. If the socket connection succeeds, another server is running and so this instance should exit. If the connection fails then it is safe to unlink the socket file and create a new one.
var fs = require('fs');
var net = require('net');
var server = net.createServer(function(c) { //'connection' listener
console.log('server connected');
c.on('end', function() {
console.log('server disconnected');
});
c.write('hello\r\n');
c.pipe(c);
});
server.on('error', function (e) {
if (e.code == 'EADDRINUSE') {
var clientSocket = new net.Socket();
clientSocket.on('error', function(e) { // handle error trying to talk to server
if (e.code == 'ECONNREFUSED') { // No other server listening
fs.unlinkSync('/tmp/app-monitor.sock');
server.listen('/tmp/app-monitor.sock', function() { //'listening' listener
console.log('server recovered');
});
}
});
clientSocket.connect({path: '/tmp/app-monitor.sock'}, function() {
console.log('Server running, giving up...');
process.exit();
});
}
});
server.listen('/tmp/app-monitor.sock', function() { //'listening' listener
console.log('server bound');
});

busybody.awesome(); // "awesome"
