Deon.land – Deno.land?

After yesterday's release of Deno with package.json support[0] some discussions about how Deno handles dependencies have been coming up again. Since Deno's inception, I've mostly been watching it from the sidelines, dabbling a bit with it, and mostly been considering it a fad that will die out sooner or later. Ultimately, with the new package.json support nothing really changed regarding the dependency management story of Deno. It's still as awful as ever. Prompted by some discussions, I decided I would try to test how easy it would be to mount a typo-domain supply chain attack. And as…

In plain words

Deon.land is a demonstration of a typo-domain supply chain attack vulnerability in Deno. The project shows how easily an attacker can register a misspelled domain and use a Cloudflare Worker to intercept and manipulate code imports in Deno projects. It highlights security concerns with Deno's dependency management system, particularly how developers copying and pasting import statements could accidentally use compromised URLs. The project is designed to illustrate existing vulnerabilities rather than provide a tool for malicious use.

    Hey all, Andy from the Deno team here. We're excited to share with you Deno Subhosting, an easy way to extend your platforms functionality by securely running untrusted JavaScript written by your users. When we first launched Deno Deploy in 2021, we were surprised at the volume of requests from companies about getting access to the APIs needed to run Deno Deploy. Many companies wanted to give their users the ability to write custom logic in their app, but setting this up in the cloud presents security concerns and a ton of infra work/maintenance. We realized that there was an…

Compression & Decompression: Compress and decompress your data. Validation: Built-in data validation using Ajv ensures your data adheres to the schema.
