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.
npm install node-ssdp
There is another package called ssdp
which is the original unmaintained version. Make sure to install node-ssdp
instead.
var Client = require('node-ssdp').Client
, client = new Client();
client.on('response', function (headers, statusCode, rinfo) {
console.log('Got a response to an m-search.');
});
// search for a service type
client.search('urn:schemas-upnp-org:service:ContentDirectory:1');
// Or get a list of all services on the network
client.search('ssdp:all');
var Server = require('node-ssdp').Server
, server = new Server()
;
server.addUSN('upnp:rootdevice');
server.addUSN('urn:schemas-upnp-org:device:MediaServer:1');
server.addUSN('urn:schemas-upnp-org:service:ContentDirectory:1');
server.addUSN('urn:schemas-upnp-org:service:ConnectionManager:1');
server.on('advertise-alive', function (headers) {
// Expire old devices from your cache.
// Register advertising device somewhere (as designated in http headers heads)
});
server.on('advertise-bye', function (headers) {
// Remove specified device from cache.
});
// start the server
server.start();
process.on('exit', function(){
server.stop() // advertise shutting down and stop listening
})
Take a look at example
directory as well to see examples or client and server.
const Client = require('node-ssdp').Client
const client = new Client({...})
interfaces
String[] List of interfaces to explicitly bind. By default, bind to all available interfaces.explicitSocketBind
Boolean Bind sockets to each discovered interface explicitly instead of relying on the system. Might help with issues with multiple NICs.customLogger
Function A logger function to use instead of the default. The first argument to the function can contain a format string.reuseAddr
Boolean When true socket.bind()
will reuse the address, even if another process has already bound a socket on it. Default: true
const Server = require('node-ssdp').Server
const server = new Server({...})
location
String URL pointing to description of your service, or a function which returns that URLlocation
Object For cases where there are multiple network interfaces or IP of the host isn't known in advance, it's possible to specify location as an object. Host will be set to the IP of the responding interface.
location.protocol
String Location protocol, defaults to http://
location.port
Number Location port. No default.location.path
String Location path. No default.udn
String Unique Device Name. Default: uuid:f40c2981-7329-40b7-8b04-27f187aecfb5
.allowWildcards
Boolean Accept wildcards (*
) in serviceTypes
of M-SEARCH
packets, e.g. usn:Belkin:device:**
. Default: false
interfaces
String[] List of interfaces to explicitly bind. By default, bind to all available interfaces.explicitSocketBind
Boolean Bind sockets to each discovered interface explicitly instead of relying on the system. Might help with issues with multiple NICs.customLogger
Function A logger function to use instead of the default. The first argument to the function can contain a format string.suppressRootDeviceAdvertisements
Boolean When true the SSDP server will not advertise the root device (i.e. the bare UDN). In some scenarios this advertisement is not needed. Default: false
reuseAddr
Boolean When true socket.bind()
will reuse the address, even if another process has already bound a socket on it. Default: true
adInterval
Number advertise
event frequency (ms). Default: 10 sec.ttl
Number Packet TTL. Default: 1800
.ssdpSig
String SSDP signature. Default: node.js/NODE_VERSION UPnP/1.1 node-ssdp/PACKAGE_VERSION
ssdpIp
String SSDP multicast group. Default: 239.255.255.250
.ssdpPort
Number SSDP port. Default: 1900
ssdpTtl
Number Multicast TTL. Default: 4
You can enable logging via an environment variable DEBUG
. Set DEBUG=node-ssdp:*
to enable all logs. To enable only client or server logs, use
DEBUG=node-ssdp:client
or DEBUG=node-ssdp:server
respectively.
Alternatively, you can provide your own customLogger
function, in which case the DEBUG
environment variable will be ignored.
