This past quarter has been awash with sophisticated npm supply chain attacks like [Shai-Hulud](https://www.cisa.gov/news-events/alerts/2025/09/23/widesprea...() and the [Chalk/debug Compromise](https://www.wiz.io/blog/widespread-npm-supply-chain-attack-b...). This CLI helps protect users from recently compromised packages by only downloading packages that have been public for a while (default is 90 days or older). Install: npm install -g @dendronhq/safe-npm Usage: safe-npm install react@^18 lodash How it works: - Queries…

In light of the ongoing npm supply chain compromises, I built safe-install: https://www.npmjs.com/package/@gkiely/safe-install It brings a couple of protections I wanted from npm but are not built in. Similar to Bun’s trusted dependencies, it lets you disable install scripts by default and define a list of dependencies that are allowed to run build/install scripts: https://bun.com/docs/guides/install/trusted It also supports blocking exotic sub-dependencies, similar to pnpm’s `blockExoticSubdeps` setting:…

Hi everyone, given the recent increase of attacks on the NPM supply chain, I've put together a list of tips and tricks to help developers stay secure on this specific topic: https://github.com/bodadotsh/npm-security-best-practices I'd love for you to check it out, and contribute your own insights and best practices to make this a comprehensive resource for the community. Cheers!

I kept seeing every npm/pnpm/yarn/bun/uv supply chain post end with the same advice (set a minimum release age, turn off install scripts), and while I know cooldowns are "controversial", they do work. But even if you convince people that they should set cooldowns, it seems many don't end up following through, not sure why, maybe because it means hand-editing five config files in five formats with five different time units, or perhaps the "it won't happen to me" syndrome (or "I'll do it later, it seems complicated" where it's actually very simple). So I created a tool that…

Excited to share the project I've been working on for the past 7 months! We've seen nearly weekly attacks against the open source software supply chain. I saw the seeds of this trend start in the mid 2015s as an open source maintainer and I've watched it only get worse over the years. I finally decided to try to solve this problem. Socket is taking an entirely new approach to one of the hardest problems in security in a stagnant part of the industry that has historically been obsessed with just reporting on known vulnerabilities. Unlike other scanning tools, Socket actually analyzes the…

The pattern of downloading and executing installation scripts without verifying them has bothered me for a while. I started messing around with a way to verify the checksum of scripts before I execute them. I've found it a really useful tool for installing things like Rust or Deno. It's written entirely as a shell script, and it's easy to read and understand what's happening. I hope it may be useful to someone else!

Pipask is a drop-in replacement for pip that addresses a serious security flaw: standard pip executes arbitrary code from source distributions during dependency resolution, without warning or consent. Pipask retrieves metadata through PyPI's JSON API first, then checks repository popularity, download counts, package age, and known vulnerabilities before allowing installation. It presents you with a pretty report and asks for you consent with installation, giving you control over what code runs on your system. More details in the intro blog post:…

I wanted a safer alternative to RegExp for TypeScript that uses a linear-time engine, so I built Regolith. Why: Many CVEs happen because TypeScript libraries are vulnerable to Regular Expression Denial of Service attacks. I learned about this problem while doing undergraduate research and found that languages like Rust have built-in protection but languages like JavaScript, TypeScript, and Python do not. This library attempts to mitigate these vulnerabilities for TypeScript and JavaScript. How: Regolith uses Rust's Regex library under the hood to prevent ReDoS attacks. The Rust Regex library…

Trusty - Search for an open source package to understand its trustworthiness based on activity, provenance, and more. Brought to you by the founders of projects such as Kubernetes and Sigstore. Hey, Luke here the CTO of stacklok. This is an early experimental preview of Trusty. We use statistical analysis to observe millions of packages and found that Malware typically follows certain patterns. We found this tool really useful to help understand the packages we our pulling into our software and wanted to share it with others. It's still early in and we have a lot more features that will be…

I built a GitHub app that detects it in pull requests, notifies or blocks them. Alongside it, I published a Semgrep ruleset for any stage of the CI/CD. I started this after getting frustrated by all the FUD around malicious code - lots of noise, little effort to solve it. Having said that, it's still a major attack vector - a stored RCE, with the codebase itself as the sink. Feedback is appreciated. The app, PRevent - https://github.com/apiiro/PRevent The ruleset: https://github.com/apiiro/malicious-code-ruleset The research:…

deptrust is a CLI that checks package versions for known vulnerabilities across npm, PyPI, crates.io, Go modules, RubyGems, NuGet, Maven, Packagist, pub.dev, CocoaPods, Hex.pm, Hackage, GitHub Actions, and more. It runs locally as a CLI and as an MCP server. It calls public package registry and OSV APIs directly; there is no hosted deptrust service. I built this because AI coding agents kept suggesting outdated or vulnerable package versions. I kept having to manually tell tools like Claude and Codex to use newer, safer versions. deptrust gives the agent a quick way to verify whether a…
