Lazarus Strikes npm Again with New Wave of Malicious Packages
The Socket Research Team has discovered six new malicious npm packages linked to North Korea’s Lazarus Group, designed to steal credentials and deploy backdoors.
Set a cookie using the same API on both the client and the server.
The set-cookie
module exports a function, setCookie
. It takes two required arguments
and one optional argument:
setCookie(cookieName, cookieValue, options);
cookieName
The name of the cookie.
cookieValue
The value of the cookie.
options
(optional)Options, such as path
, expires
, domain
. Under the hood, set-cookie
uses the cookie
module
to serialize the cookie metadata into a string. Check out that project for the
full list of options.
There is also one special option, res
, which must be passed in when using
set-cookie
from Node. It is an instance of
http.ServerResponse
,
which can come from a simple http
server or can be a Connect or Express response.
In Node, you must pass res
as an option in the third argument.
var setCookie = require('set-cookie');
// In, for example, an Express middleware.
app.use(function(req, res, next) {
setCookie('myCookie', 'the value of the cookie', {
domain: '.example.org',
res: res
});
next();
});
This would set the following HTTP header:
Set-Cookie: myCookie=the%20value%20of%20the%20cookie; Domain=.example.org
You can use a tool like Browserify to package up set-cookie
,
which uses the CommonJS module format, for use by a browser.
var setCookie = require('set-cookie');
setCookie('myCookie', 'the value of the cookie', {
domain: '.example.org'
});
This would mutate document.cookie
behind the scenes:
document.cookie = 'myCookie=the%20value%20of%20the%20cookie; Domain=.example.org'
