File uploading is a commonly needed functionality in web applications. Because of this, many web frameworks provide ways to allow server-side applications to accept files and work with them. This is the same with Fastify, which is a Node.js web framework that is often regarded as a successor to Express. It’s fast and highly focused on providing the best developer experience with a powerful plugin architecture and the least overhead possible.
‘Tis the season for a busy weekend of software supply chain attacks. Over the past three days, the Mend research team identified two separate attacks that published malicious packages to npm. Mend Supply Chain Defender quickly identified the malicious code; the owners were notified, and the packages were removed. That does not fully remove the risk, however. The first package has 9.5 million downloads, while account CI keys were compromised in the second, which can cause significant damage.
NPM security has been a trending topic in the media in recent years, mostly in reference to npm packages available on the ecosystem rather than the npm registry itself. The increasing security risk, that applies to developers and software we build, makes it even more important to understand how to prevent supply chain attacks and other security vulnerabilities related to software development life cycle.
Node.js provides a single-threaded JavaScript run-time surface that prevents code from running multiple operations in parallel. If your application typically employs synchronous execution, you may encounter blocks during long-running operations. However, Node.js itself is a multi-threaded application. This is evident when you use one of the standard library’s asynchronous methods to perform I/O operations, such as reading a file or making a network request.
Another week, another supply chain incident. It’s been only nine days since the Mend research team detected the dYdX incident, and today we have detected another supply chain malicious campaign. On October 02, 2022 at 12:12 UTC, a new npm account was registered, and a package called nuiversalify was immediately uploaded. The same threat actor then proceeded to publish more typo/spellcheck squattings of popular packages until 14:03:29 UTC, with small but irregular time gaps between uploads.
Choosing a Node.js Docker image may seem like a small thing, but image sizes and potential vulnerabilities can have dramatic effects on your CI/CD pipeline and security posture. So, how do you choose the best Node.js Docker image? It can be easy to miss the potential risks of using FROM node:latest, or just FROM node(which is an alias for the former). This is even more true if you’re unaware of the overall security risks and sheer file size they introduce to a CI/CD pipeline.
On September 11th, 2022, Snyk published a vulnerability report for the popular CSRF token management csurf npm package. The vulnerability impacts all known versions, which are currently yielding more than 400,000 downloads per week. The vulnerability report is based on the public disclosure by security consultant Adrian Tiron and their write-up on the Fortbridge blog.
